Some Novelties in Laser Driven Nonlinear Plasmonics

Plenary

Norbert KrooHungarian Academy of Sciences, Hungary

AbstractSet of unique results of nonlinear surface Plasmon (SPP) phenomena are presented. The SPPs have been excit-ed in a gold film by fem to second Ti:Sa lasers in the Kretschman geometry. Response signals to these excitations of a near field scanning tunneling microscope (STM) and spectra of SPPs assisted electron emission by the time-of-flight (TOF) technique have been studied. Abroad spectrum of room temperature experimental obser-vations is described here. Laser intensity dependent electron pairing and associated Meissner type magnetic anomalies have been found in a wide laser intensity range around 80 GW/cm2,The dynamical screening effect of electrons by the high plasmonic field is also described. Smooth and Nano structured gold films have been studied. The plasmonic field enhancement effect in the structured sample is significantly higher. The SPP assisted electro emission and acceleration effect is also described. Narrow resonances have been found in the time-of-flight spectra of electrons with anomalies in the laser intensity range of electron pairing. The temporal and quantum feature of these resonances is also discussed. Some further quantum properties of SPPs are also presented, found both in the STM and TOF electron emission data. Some of the theoretical interpretations of our findings is also discussed. Some of these findings may serve as the basis for several new applications.

Possible Implications for Discovery of Strong Radial Magnetic Field at the Galactic Center

Plenary

Qiuhe PengNanjing University, China, Nanjing

Abstract

Anomaly strong radial magnetic field near the galactic center (GC) is detected. The lower limit of the radial magnetic field at r = 0.12 pc from the GC is B≥bmG. Its possible scientific significances are following: The black hole model at the GC is incorrect. The reason is very simple as follows; the radiations observed from the region neighbor of the GC are hardly emitted by the gas of accretion disk which is prevented from approaching to the GC by the abnormally strong radial magnetic field. This is an anticipated signal for existence of magnetic mono-poles (MM). The lower limit of the detected radial magnetic field is quantitatively in agreement with the predic-tion of the paper “An AGN model with MM”. Magnetic monopoles may play a key role in some very important astrophysical problems: Nucleons may decay catalyzed by MM (RC effect according to the particle physics). Taking the RC effect as an energy source, we have proposed a unified model for various supernova explosions. And we may explain the physical reason of the Hot Big Bang of the Universe with the similar mechanism of super-nova explosion by using the RC effect as an energy source.

Optical coherence tomography-from micron to nanometer resolution

Keynote

Sheng-Lung HuangNational Taiwan University, Taiwan

Abstract

Optical coherence tomography (OCT) has been demonstrated as a powerful tool for characterizing biomedi-cal tissues as well as microstructures in semiconductors, liquid crystal display panels, photonic integrated wave-guides. Using broadband crystalline fiber based light sources from visible to near-infrared wavelength range, sub-micron resolution was achieved for non-invasive and label-free applications. The crystalline fibers were fabricated by the laser-heated pedestal growth method. Recent advancement on the co-drawing laser-heat-ed pedestal growth technique will be introduced in the talk. Since the axial resolution of OCT depends also on the center wavelength, nanometer resolution could be realized with the use of extreme ultraviolet (EUV) light source. A diode-laser seeded multi-stage fiber master oscillator power amplifier (MOPA) has been developed with millijoule pulse energy at a 6-nanosecond pulse width. To generate the 13.5-nm EUV, laser-produced plasma was excited using the MJ-MOPA system. In this talk, a novel EUV-based OCT with common-path configu-ration will be presented. As an example, the complex transfer function of a Si/Mo multilayer beam splitter is obtained. The measured thickness of the Si/Mo multilayer beam splitter agrees well with the one calculated from the fabrication parameters. The result strongly suggests the method s applicability as a new nondestructive tomographic tool for nanometer-scale actinic patterned EUV mask inspection.

The Use of Velocity Mapped Ion Imaging to Study Inelastic Scattering of Excited State Molecules

Keynote

David W. ChandlerSandia National Laboratory, United States

Abstract

Stereodynamics is the study of the impact of orientation and alignment of atoms and molecules on reactivity and the production of alignment and orientation of atoms and molecules from reactivity. One tool that has been instrumental in the observation of alignment and orientation has been the ion imaging technique with all of its variations. The use of polarized laser beams to resonantly produce ions that whose positions are measured allows one to measure, with little effort, the alignment or orientation of scattered products for a particular scat-tering velocity. Crossed molecular beam studies utilizing velocity mapped ion imaging have provided the first three and four vector-correlated studies of collisional dynamics. The crossed beams provide a definition of the incoming velocity vector and the ion imaging measures the alignment or orientation of the product for each product scattering velocity. When the reactants are produced in a manner that provides an alignment or orien-tation then four vectors are correlated and the dynamics of the collision is investigated with extreme precision. This provides a very stringent test for the theories of scattering and reactivity. Recent studies involving laser preparation of oriented species will be highlighted as well as previous studies that highlight the utility of this tech-nique for the study of stereodynamics. In particular the scattering of laser prepared and oriented NO (A N=2) with Ne will be discussed.

Strain-induced Flexoelectric Related Effects in Bi2Te3 Films

Keynote

Ning DaiChinese Academy of Sciences, China

Abstract

As a typical 3D topological insulator, Bismuth Telluride (Bi2Te3) and its alloys have recently attracted significant interests due to their unique layered structures. In fact, they are also well-known thermoelectric materials with high thermoelectric coefficient near room temperature (RT) for applications in waste-heat recovery, refrigera-tion or portable power generation, since they possess notable properties such as a prominent Seebeck effect, low thermal conductivity and high value of the carrier concentration in RT. In addition, Bi2Te3 is a narrow band-gap semiconductor (0.15 eV at RT) and has been used to fabricate infrared detectors. Herein, notable flexoelectric effect has been observed in strained Bi2Te3 films owing to the stress gradient. Utilizing this effect, the bulk photovoltaic effect (BPVE) has been extended to the infrared wavelengths in these films, which was only found in wide band-gap ferroelectric materials before. Furthermore, an anomalous thermoelectricity in strained Bi2Te3 films, i.e., the value of Seebeck coefficient S that changes after reversing the direction of temperature gradient, has also been demonstrated. This effect provides a new avenue to adjust the S of Bi2Te3-based thermo-electric materials through flexoelectric polarization.

Two-Dimensional Excitonics for Giant Optical Nonlinearity in the Near-IR

Keynote

Wei JiNational University of Singapore

Abstract

As emerged recently, Excitonics is related to the understanding, control and harnessing of optically-excited, electron-hole pairs (or Excitons) in nanoscale environments. Here, for the first time, we present our two-dimen-sional excitonic models to quantitatively predict the giant optical nonlinearity in terms of Two-Photon Absorption (2PA) and Three-Photon Absorption (3PA), for monolayer transition-metal di-chalcogenides or layered organ-ic-inorganic hybrid perovskites. Based on quantum mechanical perturbation theories, our theoretical models predict that the 2PA or 3PA coefficients should be as large as ~ 30 cm/MW, or ~ 3 cm3/GW2, respectively, at room temperature. By decreasing the operating temperature to 77 K, an enhancement of three-orders-of-magnitude should be anticipated by the models. To verify our models and to demonstrate such giant multi-photon absorp-tion for photoconduction or light frequency up-conversion, we fabricate an exfoliated monolayer MoS2 sub-band photo-detector, or layered organic-inorganic hybrid perovskites for light frequency up-converters. From photocurrent or photoluminescence measurements with femtosecond-laser-pulse excitation in the near-IR spectrum, we experimentally determine the 2PA and 3PA spectra of monolayer MoS2, or, the 3PA spectra of layered organic-inorganic hybrid perovskites, respectively. We find that our models are in agreement with the measurements, within one order of magnitude.

Multiferroic Properties in Spin-frustrated Materials

Keynote

Hung-Duen YangNational Sun Yat-Sen University, Taiwan

Abstract

Multiferroic behaviors in Spin-Frustrated systems Spine Cu2OSeO3, Kagome Cu3Bi(SeO3)2O2Cl and pyrochore Cu2OCl2 are presented. For Cu2OSeO3, it exhibits ferrimagnetic Tc and ferroelectric ordering transitions TE at T~58 K. Moreover, it show an unique so-called “Skyrmion” phase within 53 K ≤T≤ 57 K and 150 G ≤H≤ 400 G in H-T phase diagram. Splitting of skyrmion phase was observed in Zn-doped Cu2OSeO3. For Cu3Bi(SeO3)2O2Cl, without mag-netic field, an antiferromagnetic (AFM) transition is clearly established at TN ~ 25 K. Above the critical field HC ~ 0.8 T, a metamagnetic spin-flip transition from AFM to ferrimagnetic (FI) order at T ~ TN is induced anisotropically only for H // c. Simultaneously, a ferroelectric behavior is observed below T ~ TN, then a corresponding type-II multiferroics emerges above HC. The key mechanism of magnetic field induced anisotropic spin-flip and then multiferroicity in Cu3Bi(SeO3)2O2Cl can be ascribed to the breaking of magnetic two-fold symmetry in the b-c plane above HC. For Cu2OCl2, a new type of multiferroic behavior of the coexistence the collinear AFM below TN,~70 K and a long-range antiferroelectric (AFE) ordering near TN ~75 K were was observed. It also shows a new kind of mechanism of charge transfer driven antiferroelectricity in contrast to most known DM interactions observed in multiferroics. These findings provide insight into the various origins of high-TC multiferroics.

Application of Plasma in Developing Renewable Energy

Keynote

Mohamad Reza RahimpourDepartment of Chemical Engineering, Shiraz University, Shiraz, Iran

Abstract

There are different methods for the CO2 neutral fuel production. Fast pyrolysis of lignin is one of the attractive methods for this process. Due to the high oxygen content (10-45 wt.%) of the derived bio-oil, i.e. lignin, from this process, the deoxygenation of product is required. There are disadvantages of the high oxygen content of the derived bio-oil. The high oxygen content, decrease the heating value of the fuel as well as increasing the corro-sive properties of the fuel. High oxygen content also decrease the stability, increase the viscosity and caused the immiscibility of the bio-oil with other fuels. Hence bio-oil upgrading is necessary for removal of the oxygen content of the bio-oil to decrease the disadvantages of this type of fuel. In this research the bio-oil upgrading process, in a plasma reactor, was investigated experimentally for the guaiacol. Hydrodeoxygenation of guaiacol was performed in a combination of dielectric barrier discharge plasma reactor and different commer-cial catalysts. Catalysts contain the Ni, Co-Mo, Ni-Mo, Pt-Re and Pt-Cl active sites supported on alumina struc-ture. The required hydrogen in hydrodeoxydeation reaction, was provide by cracking of the methyl groups of the guaiacol structure. The effect of operating parameters, including the applied plasma voltage, guaiacol flow and argon flow rate was investigated in the conversion efficiency of guaiacol. Results indicated that the maximum conversion of guaiacol was 92%, while the maximum deoxygenation degree was 65% in the presence of Pt. type catalysts. The conversion of guaiacol was increased by increasing the applied voltage and increas-ing the argon flow rate up to 150 ml.min-1. However decreasing in the guaiacol flow rate, increase the conver-sion of guaiacol.

Mid-IR Fluoride Fibers for UV-VIS-Mid-IR-fiber lasers

ORAL TALK

Mohammed SaadThorlabs Inc, United States

Abstract

Fiber lasers have attracted a lot of attentions, because of their multiple advantages compared the other lasers technologies, such as semiconductor, gas and solid state lasers. Fiber lasers are compact and have high efficiency, excellent beam quality and exhibit good heat dissipation. They are currently used in many industrial (drilling, cutting and welding…) and high tech applications, such as defense and aerospace, medicine, spec-troscopy and sensing. Since the first demonstration of the first fiber laser in 1964, by Snitzer et al., two research directions have been investigated; scaling the output power and investigating new laser lines. High power output fiber lasers have been already demonstrated using silica doped fibers. Fiber lasers with kilo watts output power have been achieved and used in industrial applications. As far as new wavelengths fiber lasers are concerned, other glass hosts have been intensively investigated, such as fluoride, phosphate, chalcogenide and tellurite glasses. No one of these glasses can fulfil the need of all applications. Scientist and engineers have to consider the right glass host for the right application. However, the right candidate has to combine the ability to be drawn into high quality single mode optical fiber, have a high solubility of rare-earth ions and the ability to be cleaved and spliced. A wide transmission window is also advantageous along with the ability to write Bragg Gratings in the fiber to tailor the emission characteristics. The presentation will report the latest development in fluoride glass fiber technology and their applications

Laser Induced Damages in Multilayer Oxide Thin Films

ORAL TALK

Ajay ShankarGuru Jambheshwar University of Science and Technology, India

Abstract

High power laser beam generation and manipulation depends on laser induced damages threshold (LIDT) of optical components used in the system. LIDT for such components having multilayers thin film coatings used to improve performance of coatings has been subject of intensive investigations. We studied conventional elec-tron beam deposited multilayer coatings made with lower index oxide essentially SiO2 and examining perfor-mance variations with its combination with a set of high index materials layer TiO2 ,Ta2O5 ,and HfO2 on Quartz-/BK-7 substrate all quarter wave optical thickness (QWOT) and with few outer non-QWOT layers. One of our primary aims is to study effect of multilayer boundary and related effect for their combination as all quarter wave high and low index material films layers when number of layers increases as well allowing upper two non-quarter wave thickness layers. One of critical parameter observed to effect the LIDT were found to be loca-tion of electric field peaks proximity with the boundaries of low and high index layers in any multilayer laser optics particularly at few front boundaries where field strengths are invariably high. Reflection spectra of these samples shows a relatively small decrease in reflection in non-quarter wave layer design and GIXRD showed that deposit-ed films are amorphous, sufficient high refractive index and very low extinction coefficient or low absorption as factors favorable for high laser induced damage threshold. LIDT studies were needed to be performed starting with S single layer of oxides to all quarter wave and combination of QWOT and non-QWOT to adjust field positions increasing LIDT of coated multilayer stack.

Electron acceleration by radially-polarized laser pulses in plasma micro-channels and from solid wires

ORAL TALK

Meng WenMax-Planck-Institut für Kernphysik, Germany

Abstract

Encouraged by recent advances in radially-polarized laser technology, three-dimensional Particle-In-Cell simu-lations have been performed of electron acceleration by an ultra-short pulse in a parabolic plasma micro-chan-nel and along a solid-wire. In the micro-channel, milli-joule laser pulses, generated at kHz repetition rates, are shown to produce electron bunches of MeV energy, pC charge, low emittance and low divergence. The pivot-al role played by the channel length in controlling the process is demonstrated, and the roles of direct and Wakefield acceleration are distinguished. With a solid target, electrons may be generated and subsequently accelerated to energies of the order-of-magnitude of the ponderomotive limit, with the underlying process dominated by direct laser acceleration. Breaking this limit, realized here by a radially-polarized laser pulse incident upon a wire target, can be associated with several novel effects. Simulations show a relativistic intense laser pulse can extract electrons from the wire and inject them into the accelerating field. Anti-dephasing, resulting from collective plasma effects, are shown to enhance the accelerated electron energy by two orders of magnitude compared to the ponderomotive limit. It is demonstrated that ultra-short radially polarized pulses produce super-ponderomotive electrons more efficiently than pulses of the linear and circular polarization varieties.

Effect of Particle Size on Optical Properties of Vanadium Oxide Nanoparticles

ORAL TALK

Devendra MohanGuru Jambheshwar University of Science and Technology, India

Abstract

Linear and nonlinear optical properties of electro-deposited Vanadium Oxide mesoporous structure on ITO sheet have been studied. The characterization is done using UV-VIS-NIR spectrometer, SEM, FTIR and XRD. A good transmission has been observed in IR range and there is increase in band gap due to decrease in grain size resulting blue shift of light emission band. Nonlinear behavior measurement has been studied using a single beam Z-scan method with He-Ne Laser of λ~632 nm. The nonlinear refractive index and the nonlinear absorption coefficient of samples have been determined for nano-particle sizes ranging from 10 to 40 nm. However, the nonlinear absorption coefficient rapidly decreases with increase in particle size. The third order nonlinear susceptibility of all the samples is also calculated and discussed. It is observed that the response of the V2O5 nanostructures to the incident laser beam varies depending on the particle size. The increase in optical suscepti-bility due to decrease in particle size make the Vanadium Oxide as a potential material for optoelectronic devices.

Atom-field enhanced coupling in structured plasmonics: Periodic nanowire array on material substrate

ORAL TALK

Ali Al-Kamli Jazan University, Jazan, Saudi Arabia

Abstract

We explore atom-field enhanced coupling in a novel structure consisting of nanowire (NW) array periodically deposited on the planar interface separating two media: vacuum and material substrate. The surface modes (SM) can be surface plasmons, surface phonons, surface excitons or any other type of surface modes that the material substrate supports. The NW system provides SM confinement in the direction normal to the NW array in addition to the inherent confinement transverse to the interface between the vacuum and the substrate. Such 2-D confinement with rich and controllable parameters can be utilised to generate strong coupling for the inter-action of these surface modes with atomic systems localised near the structured interface. In order to quantify such effects, standard methods are developed and used to determine the dispersion relations and the corre-sponding field functions which lead to the evaluation of the coupling ( e.g. de-excitation rate) for an emitter localized in the structure. The rate/coupling depends critically on various parameters, including the position of the emitter, the nature of the wires and their dimensions, their separation as well as the type of substrate on which the wires are deposited. Orders of magnitude coupling enhancement are attainable with conservative choice of structure parameters. Emitters in the vicinity of structured surfaces are envisaged to be the basis of quantum architectures leading to the realisation of scalable quantum information processing. Possible future applications are also discussed.

Double and Triple Autoionization of Atomic Ions Atoms

ORAL TALK

Shahin Ahmed Abdel Naby American University of Sharjah, United Arab Emirates

Abstract

A time-dependent close-coupling (TDCC) method was successfully used to study ionizations arising from inter-actions of electrons, photons, and ions with small atoms and molecules. Currently, this method is developed to handle a four-electron system initially in an excited state such as C2+ (2s22p2). The C2+ (2s22p2) excited state can be obtained by relaxation of Schrodinger’s equation in imaginary time. Double, triple, and total autoionization rates for C2+ are obtained by propagation in real time using projections onto products of bound and continuum single particle states. This work was motivated by recent experimental measurements of single, double, and triple autoionization of C+ ion by single photons. Future developments for the TDCC approach are underway to handle a five-electron system with interior subshells such as C+ (1s2s22p2).

Implantation-induced Lattice Strains and Defects in InAs0.93Sb0.07 films

ORAL TALK

Huiyong DengChinese Academy of Sciences, China

Abstract

The ternary alloy InAs1-xSbx is a promising material for infrared optoelectronic device applications such as infra-red laser, LED and photodetector, due to its better stability than popularly-used HgCdTe. Owing to light atom mass and low damage introducing rate, Be ion is a good choice for p-type doping in InAs1-xSbx through ion implantation. Unfortunately, ion implantation is a non-equilibrium technique, which often causes lattice damag-es. Herein, InAs0.93Sb0.07 epitaxial layer grown by liquid epitaxy growth (LPE) was implanted with Be ions. The char-acteristics of damage buildup and its removal by rapid thermal annealing at temperature 500 °C were investi-gated by high resolution X-ray diffraction and TEM. The implantation-induced nonlinear maximum perpendicu-lar strain εm as a function of the Be fluence was obtained. The nonlinear strain was analyzed in terms of point defects. In addition, we found that the caused damages can be recovered by rapid thermal annealing at 500 °C for samples with the fluence below 1.0×1015 cm2. Nano-sized residual damages after annealing at 500 °C, however, were still observed when the fluence reaches 4.0×1015 cm2. Those residual damages might originate from poor recrystallization of the small disorder region.

Study of the Structural, Microstructural and Thermal Characterization of 5% Fe-doped ZnO Powder Nanostructures Prepared by Mechanical Alloying

ORAL TALK

Abstract

ZnO powder nanoparticles mechanically alloyed were doped with iron to investigate their structural and microstructural properties using X-ray diffraction (XRD) and differential scanning calorimetry ( DSC ) for exam-ined 5% Fe doped ZnO. The ZnO starting pure powder exhibited a hexagonal crystal structure with space group p63mc of ZnO, however with the introduction of 5% Fe in the ZnO milled powder, the hexagonal ZnO phase remained unchanged, whereas the microstructural parameters were subject to significant variations due to the introduction of Fe atoms into the ZnO hexagonal matrix to replace oxygen ones. The size of crystallites and microstrains are found milling time dependent.

Nature of Physical Reality: A Critical Assessment of Material Realism

ORAL TALK

Behnam M. ZadeganRetired University Professor, USA

Abstract

After Renaissance, European natural scientists and philosophers agreed on a scientific view of the nature of physical reality based entirely on Newtonian physics. The agreed view on the nature of reality has been known as material realism. This paper presents a critical assessment of the set of scientific facts which proponents of material realism had agreed up on in support of their post-Renaissance view on the nature of reality. First, for the sake of clarity, this set of scientific facts, is specifically described. Next, these scientific facts are critically assessed in light of specific scientific discoveries which took place after the late 1870’s. This paper argues that scientific discoveries after the late 1870’s, do not support the principle assumptions of the material realism view on the nature of reality. Specifically, the relevance of a number of well-known scientific discoveries, including Maxwell’s electromagnetic theory, quantification of photon energy and the photon-electricity phenomenon, Planck’s blackbody radiation, Einstein’s general relativity theory, Hubble’s observations on the universe’s expansion, Einstein’s field equations and quantum theory arepresented in more details.

Nanometric study of transport phenomena in InN / InP semiconductor electronic devices.

ORAL TALK

Hadjadj BrahimUniversity Djillali liabes of Sidi Bel Abbes, Algeria

Abstract

The III-V compound semiconductors based on nitrogen (InN, GaN), are today very promising in the field of microelectronics and optoelectronics. Element III nitrides are particularly attractive substrates for short wave-length optoelectronic applications. The major advantage of this family of materials lies in their very wide band gap and their electronic properties of saturation speed and high breakdown field. In the field of microelectron-ics, nitrides are the best candidates for all high temperature, high power or high frequency applications. III / V semiconductor substrates such as InP are valuable materials for the growth of InN potentially. However, the characteristics of the resulting heterojunctions are closely related to the surface and the interface state. This work deals with the nanometric study of the transport phenomena in the electronic devices of III-V and III-N semiconductors, in particular InP and InN.

Investigations of plasma into the magnetically uniform Confined plasma

ORAL TALK

Samir Suliman YassinIslamic University of Gaza, Gaza

Abstract

One of the most important purposes of magnetic confinement is to keep the hot plasma away from the wall of the vacuum vessel. The temperature required to sustain fusion reaction is the order of 10 Kev. The interaction between charged particles and magnetic field , are used to keep hot plasma from coming contact with the wall the vacuum vessel . Some of the ions escape from the hot plasma reaches a layer , and interact with the impurity atoms of high atomic mass into the vacuum area . The machine is been modified to provide high densi-ty of plasma. The plasma is produced externally from source , and confined in a cylindrical geometry at low magnetic 1kG. The calculation has been made and suggested that the ion beam in the solenoid will have a maximum radius of twice the Larmor radius , while the density is a complex function of the ratio B (Z.)/Bm. The low density obtained , suggesting that losses due to mirroring may be occurring that is the plasma source should be closer to solenoid to provide good plasma injection.

Synthesis and Luminescent Properties of from Pb- doped MgAl

2O

4 prepared by the a sol - gel

combustion method

ORAL TALK

Wael A. TabazaIslamic University of Gaza, Gaza

Abstract

Magnesium aluminate (MgAl2O4) has received special attention as a technologically important material because of its attractive properties, such as mechanical strength, a wideband gap, chemical inertness, relative-ly low density, high thermal shock resistance, high melting point, low thermal expansion coefficient and low dielectric loss. It has also been used as a phosphor host activated by a variety of transition metal and lanthanide ions. As an alternative to such ions, luminescence can often be obtained from the ns2 type ions such as Tl+, Pb2+, Bi3+ and Sb3+. For Bi3+ the luminescence is attributed to the electron transition between the 6s2 ground state and the 6s16p1 excited states. Nanocrystalline Magnesium aluminate (MgAl2O4) doped with Pb was synthesized using the sol-gel technique where by the Pb2+ concentration was varied in the range 0–1.5 mol%. The effect of Pb2+ concentration on the structure, particle morphology and photoluminescence properties of MgAl2O4 were inves-tigated. The samples thus obtained were characterized by X-ray diffraction (XRD), UV–vis spectroscopy, scan-ning electron microscopy and photoluminescence spectroscopy (PL). The XRD data showed that all the sam-ples had the spinel structure and the average particle size of the as-prepared samples was about 27 nm. For an excitation wavelength of 280 nm, the Pb2+doped MgAl2O4 produced a broad blue emission band centred near 400 nm, indicating that Pb2+ ions were successfully incorporated in the lattice. Maximum blue emission was obtained for the sample doped with 0.75 mol% Pb.

Self-assembly of PVPylated Surfactants into Stable Niosomes as Potential Pharmaceutical Carriers

ORAL TALK

Muhanna K. Al-MuhannaKing Abdulaziz City for Science and Technology, Saudi Arabia

Abstract

A range of novel, nonionic polymeric surfactants containing short, hydrophilic polymeric chains polyvinylpyrro-lidone PVP have been investigated for their ability to form vesicles for drug delivery. The designated formula of these surfactants was 2CmglyVPn where m is the length of the hydrophobic chains, n is the length of the hydro-philic head group, and gly that surfactants contained a glycerol backbone. The length of the hydrophilic head groups ranged from 25 to 50 while the length of the two hydrophobic chains present ranged from C12 to C18. The ability of the polymeric surfactants to form vesicles, both in the absence and presence of cholesterol, using the thin film method in combination with probe sonication investigated using a range of analytical techniques, specifically light and neutron scattering, electron microscopy and dye entrapment studies. The change in aggregate size with duration of probe sonication assessed using light scattering, as was vesicle stability over time. Small angle neutron scattering (SANS) studies confirmed the presence or otherwise of vesicles and, in the case of vesicle formation, allowed quantification of the thickness (and where appropriate the repeat distance) of the vesicle bilayers. The effect on vesicle formation of 0.9M sodium chloride was also established by SANS. The dye entrapment and electron microscopy studies confirmed the results of the light scattering and SANS studies. The stability of the aggregates to incubation for 24 hours with human blood plasma at 298 and 310 K was assessed by monitoring the release of any entrapped CF. In order to form stable vesicles, the PVP-based surfac-tants needed to be mixed with at least 50 mol % cholesterol. In contrast, the PAM-containing surfactants did not appear to readily form vesicles even when mixed with cholesterol at 66 mol %.

Open Shell Ions Mobility in Cooled Helium Gas at Low Temperature

ORAL TALK

Lamia AISSAOUILahdj Lakhdar-Batna 1 University, Algeria

Abstract

This project aims to show the effect of the Spin-Orbit (SO) and the quantum-mechanical calculations on the behavior of C+ and N+ and O+ ions mobility in a cooled buffer helium gas at 4.3K. For this reason, we used the interaction potentials corresponding to the ground and metastable-excited ions which are performed with MOLPRO. Then we employ the computed quantum-mechanical transport cross sections of ion atomic and neutral atomic elastic collision in the Viehland gram-char Fortran code as to get the mobility of open shell ions at 4.3K helium gas temperatures. The obtained results are compared with those of the experimental measure-ments of Matoba et al, and Sandreson et al, with a mass-selected-ion-injected drift tube mass spectrometer. The theoretical values of C+ and N+ and O+ ions mobility don’t display the shallow minimum around 10 Td that is showed by the experimental values.

Dissociation of molecular hydrogen induced by fast electrons

ORAL TALK

Kousik SamantaIndian Institute of Technology, Bhubaneswar, India

Abstract

In the interaction of energetic particles or photons with molecular hydrogen (H2), an important outcome is the generation of protons. In this work, we have studied the generation of protons due to dissociative ionization of H2 as a result of collision with fast electrons of energy 6 keV. The yield of protons and their kinetic energy (KE) have been measured at different angles (θ) with respect to the direction of the incident beam of electrons. The distributions of the KE at different θ show two distinct peaks at 5 and 8 eV of proton energy. The 5-eV protons are relatively more abundant at smaller observation angles (θ ~30º ), while the 8-eV protons dominate at larger angles (θ ~100º ). An estimation based on the Franck-Condon principle reveals that the dissociation of 2pπu and 2pσu states of H2+ are responsible for the generation of 5- and 8-eV protons, respectively. Directional preferenc-es for the production of 5- and 8-eV protons are explained using an analysis of the transition dipole moments.

Photodetachmennt of Atomic Negative Ion in the Presence of Nano-Surface

ORAL TALK

Muhammad HaneefHazara University Mansehra, Pakistan

Abstract

Photo detachment of Atomic negative ion in the vicinity of nano-surface has been investigated. Atomic nega-tive ion, if exposed to light behaves detaches electron. The detached electron tags by a wave packet which is greatly manipulated by the presence of Nano-surfaces. The wave packet is exploited for the derivation of photo detachment cross section. The reflection and tunneling of waves from nano surface is discussed. Size of the surface along the absorption parameter strongly influence the photo detachment spectra. However, a fine control on these parameters can be used to investigate the information of negative ions, curvature, and rough-ness in the surface at Nano scale.

Computational study of the interactions between CO

2 and Zn2+-triazole complexes

Poster

Saida Ben Yaghlane LSAMA, Université de Tunis El Manar, Tunis, Tunisia

Abstract

DFT calculations with inclusion of dispersion correction (M05-2X+D3) have been performed to investigate the complexes of CO2 with the Zinc(II)–Triazole ( [Zn2+-Tz] ) isomers and tautomers. We identified their equilibrium structures and binding energies in the gas phase and solvated in aqueous solution. The most stable structures correspond to strong electron donor-acceptor complexes, in which a covalent bond between CO2 and Zn2+ is established. Besides, the bonding between Tzs and CO2 is due to non-covalent interactions such as σ H-bond and π-stacking. The mechanism of tautomerization between two equilibrium species : CO2@[Zn2+-(1H-1,2,3-tri-azole)] and CO2@[Zn2+-(2H-1,2,3-triazole)], identified during the optimization of CO2@[Zn2+-Tz] complexes in the gas phase and in water, is also studied by employing M05-2X+D3 functional along with the 6-311++G** basis set. The results suggest that the formation of first complex, labeled CO2@[Zn2+-1A]a,S2 , dominates over the second one, labeled CO2@[Zn2+-1B]a,S3 , in the gas phase, whereas the potential barrier is lowered in the presence of water as observed for other tautomeric systems. Our finding are used to predict a nitrogen rich type MOF

Elaboration and spectroscopic, thermal, structural and electrical investigation of the Polystyrene/Polyaniline composites

Poster

Nacira NAAR Université des Sciences et Technologies Houari Boumediene, Algeria

Abstract

However, intrinsic conductive polymers (ICP) have disadvantages such as insolubility and fragility due to their poor mechanical properties. To remedy these problems, these polymers must be combined with thermoplastics polymers (PP, PMMA, PS ...) in order to produce composites combining electrical properties with interesting mechanical properties for applications in several sectors of advanced technology. The present work consists of the development of polyaniline-based composite as reinforcement and polystyrene. The composites were prepared by two different methods: by in situ polymerization and Co-Mixing. Polyaniline (PANI) is synthesized by interfacial oxidative chemical polymerization in the presence of 5-sulfosalicylic acid as a dopant and according to its structure. Polystyrene is prepared by emulsion process, in the presence of SDS as an emulsifying agent and APS as a reaction initiator. The prepared samples were analyzed by different characterization techniques: spec-troscopic (FTIR), thermal (TGA), structural (DRX), morphological (SEM) and electrical (electrical conductivity). The developed composites are intended for dissipation charges and the antistatic domain.
