Graphical Abstract
Figure 1 shows the flow of the preparation of samples. For wet milling method, distilled water is added about 40 ml then undergo
milling process, while for dry milling method the mixture of the raw materials undergo milling process without distilled water. The
dry milling method is a proper method to obtain fine and homogeneous glass powder (Sarrigani and Amiri, 2019).

Abstract
Ceramic sintered pellets with a chemical composition of 96 mol% ZnO-2 mol% CoO-2 mol% SLS glass were prepared using solid
state method at different milling method i.e wet and dry milling. Milling is one of the processes in the preparation of powder
mixture. The purpose of this study was to find the effect of milling methods which produce the best homogeneity mixture and relate
to the electrical properties of the samples prepared. A comparison in the microstructural and electrical properties of the samples
obtained by both milling methods was made. The best results on these characteristics were achieved through the dry milling
methods at 2 mol% SLS glass concentration, obtaining a nonlinear coefficient of 6.973 and a breakdown voltage 261.139 V/cm.
The samples synthesized by this technique show not only high density value, 96.11% of the theoretical density, but also a
homogeneous microstructure, which compete with those obtained by the wet milling methods.

Effect of Eu3+ Concentration on Luminescence Properties of ZnO/Zn2SiO4 Composite

Graphical Abstract
Figure shows the prominent emission peak is found at 615 nm with the electronic transitions 5D0→7F2. At 615 nm, the strong
emission peak of Eu3+ ZnO/Zn2SiO4 which is characteristically red emission was attributed to magnetic dipole (MD) transitions.
This peak shows that the Eu3+ ions had occupied the non-centrosymmetric site in the Zn2SiO4 crystal lattice. Rare earth elements
share many similar properties and these elements can be identified by 4f orbital that is partially filled with electrons which is, f–f
transitions of electrons can bring to the light absorption so that the spectral characteristics will changed. In addition, the electronic
energy levels of rare earth element are extremely different contrast to other elements. This is due to their ability to absorb or emit
the electromagnetic wave of various wavelengths. As example, Eu2+ ions show an emission accompanied by a transition of electrons
from the 4f6 5d1 excited-state to the 4f7 ground-state. In this work, for the Zn2SiO4 host crystal, Eu3+ ions emit red (> 610 nm)
regardless of the type of host crystals, since the emission derives from a transition of the 4f6 electrons in the 4f inner shell. Using
Eu3+ as a doping candidate will exhibit red-emission of 610-615 nm in Zn2SiO4 host crystals. The increasing of Eu3+ concentration causes an increase in emission intensity until the doping concentration reaches x = 10 mol.%. Besides, the increase in Eu3+ doping
concentration also causes the dominant peak of the emission spectra to shift from higher wavelength to lower wavelength (605 nm
to 615 nm) which can be well explained by the Zn-O-Si expansion lattice phenomenon.

Abstract
New Eu3+ doped Zn2SiO4/ZnO phosphor-based composites were successfully prepared using a simple thermal treatment method.
The influence of Eu3+ content on the morphological and photoluminescence performance of the obtained sample was examined
using XRD, FTIR, FESEM, UV-Vis, and PL measurement. The existence of two crystal phases by the XRD measurement
confirmed the formation of zincite (ZnO) and zinc silicate (Zn2SiO4) crystal phases. The progress of Eu3+ content in the structure
has affected the crystal peaks to become sharper. Besides, the FTIR spectra and FESEM micrograph support the XRD result by
verifying ZnO and Zn2SiO4 phases formation through the existence of their characteristic Zn–O–Si and Zn–O vibration modes with
the decrement of SiO4 broad absorption band as the Eu3+ concentration increased. Also, UV-vis absorption spectra presented by
the composite samples displayed a broad absorbance that confirmed the addition of Eu3+ ions in the ZnO/Zn2SiO4 has caused the
absorption edge of the curve having red-shift. Furthermore, the composites showed broadening emissions in a visible range as a
result of PL from both ZnO and Zn2SiO4 crystal phases. The photoluminescence spectrum showed red shift light emissions at 485
and 615 nm, associating with the Zn2SiO4 crystal phase, in addition to the ZnO crystal phase. From the interesting results achieved,
this ZnO/Zn2SiO4 phosphor-based composites material can be a potent candidate in optoelectronic applications.

Graphical Abstract
Referring to Figure 1, the XRD measurement at 27˚C showed that the atomic structure in the glass sample was amorphous in
nature, where the arrangement of atoms in the precursor glass sample was unstructured and randomly organized. However, the
amorphous structure of the precursor glass changed when it was subjected to the heat-treatment process. Figure 1 displays the
XRD pattern of the glass and glass-ceramic sample against heat-treatment temperature. When the glass sample was treated at
600˚C, the arrangement of atoms in the glass structure remained unorganized. The structure change started to take place when the
heat-treatment temperature was increased to 700˚C. At 700˚C, several diffraction peaks started to appear, indicating the formation
of zinc silicate crystals.

Abstract
A new transparent zinc silicate glass-ceramic was derived from the 55ZnO–5B2O3–40SLS glass system via a controlled heat-
treatment method. The precursor glass sample was placed through the heat-treatment process at different temperatures to study
the progress in phase transformation, optical performance and emission intensity of the zinc silicate glass-ceramics. For this
project, material characterization was measured through several tests using densimeter and linear shrinkage measurement, X-ray
diffraction (XRD), Fourier transform infrared reflection (FTIR), ultraviolet–visible (UV–Vis) and photoluminescence (PL)
spectroscopy. The density and linear shrinkage measurements show that the density of the particular glass-ceramic samples
increases with the progression of heating temperature. The XRD analysis display the result in which the zinc silicate crystal starts
to grow after the sample was treated at 700˚C. In addition, the FTIR spectra indicated that the crystallization of the zinc silicate
phase occurred with the appearance of SiO4, ZnO4 and Si-O-Zn bands. UV–visible exhibited the small changes when the value
for the optical band gap decreased from 3.867 to 3.423 eV, influenced by the temperature applied to the sample. Furthermore, the
PL spectroscopy showed an enhancement of broad green emission at 534 nm upon the increased heat-treatment temperature. Thus,
it can be concluded there is the progression of crystal growth as the heat-treatment temperature increased; three emission peaks
appeared at 529, 570 and 682 nm for the green, yellow and red emissions, respectively.

Graphical Abstract
It can be observed that the pore’s size, the thickness of the pore’s walls, and pore’s distribution varied in different sintering
temperatures. The highest total porosity can be observed at 800°C, where the pore’s diameter is the bigger with thinner pore’s walls
and well distributed. While the smaller pore’s diameter with a lack of porous distribution which leads to very low total porosity
can be seen at the image of 700°C.

Abstract
Foam glass-ceramics derived from waste materials can be a low cost alternative and sustainable solution for construction industry.
Therefore, foam glass-ceramics produced from soda lime silica (SLS) glass bottles and clamshell (CS) were produced to investigate
its physical, structural and mechanical properties. This study used 3wt% of CS contents where the prepared powder was compacted
into pellet form prior to sinter at 700-900°C for 1 hour. The minimum density (2.43g/cm3) with maximum expansion (83.98%) was
obtained at 800℃ sintering temperature. The XRD measurement show the wollastonite (CaSiO3) crystalline phase has formed at
800℃ and its crystallinity were increase at a higher sintering temperature. The highest value of mechanical strength (1.21 MPa)
with acceptable high total porosity value (58.27%) was obtained at 900℃ sintering temperature indicates that the fabricated foam
glass-ceramics have potential for building materials. FESEM micrograph has visualize the porous structure of foam glass-ceramics
samples at 800℃ sintering temperature has the largest porous structure with closed pore characteristic. Keywords: Foam glass-ceramics, compressive strength, clamshell, glass, porosity, waste

Figure 1: The compressive strength of GIC on different ageing times and sintering temperatures.
Abstract
In this research, GIC had been fabricated from Alumino-silicate-fluoride (ASF) based glass ceramics derived from waste material
of CS and SLS glass. The ASF based glass ceramics were synthesized by using conventional melt quenching technique and
controlled sintering process of 600 and 800 °C. The GIC sample were analyzed at 7, 14, 21 and 28 days of ageing time. The
properties of ASF glass ceramics and GIC had been determined by using x-ray diffraction (XRD), fourier transform infrared
spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive x-ray (EDX) and compressive
strength (Cs). The XRD analysis revealed Ca5(PO4)3F (fluorapatite) as a major phase in the GIC sample. Next, FTIR revealed a
presence of CO3 group, Si−O−Si, P−O, crystalline phosphate, CH3 and O−H band which indicates structure of glass matrix and
crystallization of GIC sample. The uniform spherical microstructure was observed in FESEM as a result of glass crystallization.
The EDX analysis revealed Ca/P ratio obtained around 2.14-3.36 is suitable for body implantation. The compressive strength
obtained in the range of 17.3-82.03 MPa. Basically, the minimum compressive strength value for glass ionomer (luting cements)
following to International Organization for Standardization (ISO 9917) is 70 MPa. The GIC becomes a potential candidate for
clinical application in dentistry due to excellent adhesion and good biocompatibility towards biological system.

Abstract
In single-band model, the transitions of the charge carriers are observed between the lowest unoccupied molecular orbital (LUMO)
of the conduction band and the highest occupied molecular orbital (HOMO) of the valence band. In this paper, a mathematical
approach in estimating the transition energy of type-II core-shell quantum dots (CSQDs) is analysed in both strong and weak
confinement cases. It is shown that the transition energy in strong confinement would increase by 50% compared to 20% in the
weak confinement case, for which the charge carriers under weak confinement can be inferred as pseudo type-II CSQDs.

Graphene/germanene superlattice is made by stacking together graphene monolayer and germanene monolayer vertically.

Abstract
We study the structural and electronic properties of graphene/germanene superlattice using density functional theory. Here, we find
that the graphene and germanene are bound together mainly by weak van der Waal forces in the superlattice. This is supported by
small interlayer binding energy of graphene/germanene superlattice. The most stable superlattice stacking is the top stacking
configuration followed by bridge and hollow. In the superlattice, the Dirac cone characteristics of both graphene and germanene
layers is well preserved. The band gap opening at K-point is found due to the unsaturated pz-orbital of germanene layer.

Abstract
Yttrium-substituted bismuth ferrites (BiFe1-xYxO3 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5)) ceramics were successfully synthesized via
modified thermal treatment method. The effects of Y-substituted BFO on the structural, morphological, magnetic and microwave
absorption properties were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM),
vibrating sample magnetometer (VSM) and professional network analyzer (PNA). The XRD analysis showed the BFO sample was
matched to hexagonal structure which belongs to the R3c space group. The Y-substituted BFO showed phase transformation from
hexagonal to orthorhombic. Pure BFO gives the highest value of grain size of 354 nm. From FESEM analysis, the grain size of Y-
substituted BFO samples decreased as the amount of Y-substitution increased. The grain size ranges from 90 nm to 354 nm. From
VSM measurements, the BFYO sample at x=0.2 gives the highest saturation magnetization (Ms = 3.9494 emu/g) and remnant
magnetization (Mr = 1.2115 emu/g) value. The microwave absorption properties of all samples with 1 mm thickness and at the
frequency range of 8-12 GHz (X-band) are influenced by the amount of Y-substitution in BFO. Pure BFO gives the minimum value
of reflection loss (RLmin) less than -5 dB whilst the Y-substituted BFO caused the RLmin of all samples more than -3 dB compared
to the pure sample. The dielectric properties of Y-substituted BFO caused the dielectric constant (ε′) and loss factor (ε″) to decrease
with frequency for all the samples.

Graphical Abstract
This work reports the physical properties of bulk and nano-sized NSMO. They are excellent with colossal magnetoresistance by
tunable grain size via different preparation methods.
Figure 1: Physical properties and potential applications of NSMO.
Abstract
Colossal magnetoresistive (CMR) manganites have attracted great research interest and studied extensively since its discovery.
However, the work of the neodymium-based system is limited and less attention has been paid to Nd0.7Sr0.3MnO3 (NSMO). This
work reports the NSMO prepared by solid-state reaction and sol-gel method to obtain the manganites with different particle sizes.
NSMO size variation could influence significantly on the magnetic and magneto-transport properties. More interestingly, nano-
sized manganites display unusual physical properties compared to its bulk counterparts. Bulk and nano-sized NSMO crystallised
into the orthorhombic crystal structure and have a strong orientation towards (121) plane. The peak broadening can be observed in
nano-sized NSMO indicates it has the smaller crystallite size. The average grain sizes for bulk and nano-sized NSMO are ~ 607 nm
and ~ 26 nm respectively as revealed from the field emission scanning electron microscope. The AC susceptibility results showed
that Curie temperature (TC) decreases as the grain size decreases. This behaviour can be attributed to the loss of long-range
ferromagnetic ordering in nano-sized grains. The strong suppression of the TMI has been observed as the particle size goes down.
NSMO has recorded the magnetoresistance of 27.7 % near the TMI, which attributed to the increase of disordered magnetic spin
fluctuations in the high-temperature range. This work revealed that the physical properties of NSMO can be modified by the particle
size. Therefore, the tunable grain size behaviour of NSMO by different preparations are highly feasible to be applied in the high-
performance magnetic field sensor. 1-3

Abstract
In this work, magnesium diboride, MgB2 samples were prepared by using magnesium, Mg powder and carbon-encapsulated boron,
B powder (1.35 wt.% carbon) with addition of dysprosium oxide, Dy2O3 and lanthanum oxide, La2O3 as dopants. Different weight
percentages with the ratio of x wt.% Dy2O3: x wt.% La2O3 were used where x = 0.00, 0.25, 0.50, 0.75, 1.00, respectively. X-ray
diffraction (XRD) results indicated MgB2 as the major phase for all the samples. Magnetization measurement showed a slight
decrease of critical temperature, Tc from 38.1 K to 37.6 K with the co-addition of Dy2O3 and La2O3. Self-field critical current
density, Jc at 20 K increased with the increasing of co-addition levels probably due to improved grain coupling. The highest self-
field Jc obtained is 433 kA.cm-2 with 1.00 wt.% co-addition level. Field dependent Jc ( 4 T) at 20 K of the co-added samples is
higher compared to that of the pure one. The present results show that a small amount of Dy2O3 and La2O3 co-addition into MgB2
is effective to enhance flux pinning and Jc.

Abstract
High temperature superconductor (Tl0.85Cr0.15)Sr2CaCu2O7-δ (Tl-1212) with addition of zinc ferrite (ZnFe2O4) nanoparticles were
synthesized using high purity oxide powders through a solid state reaction method. ZnFe2O4 nanoparticles with composition of
0.01 wt.%, 0.02 wt.%, 0.05 wt.%, 0.10 wt.%, and 0.15 wt.% were added to the Tl-1212 superconductor. These Tl-1212 samples
were characterized using scanning electron microscopy (SEM), powder X-ray diffraction method (XRD), energy dispersive X-
Ray analysis (EDX), electrical resistance measurement, and transport critical current density measurement. All samples
indicated Tl-1212 phase of a tetragonal structure with a secondary phase/impurity of CSCO. The transition temperatures (Tc-zero
and Tc-onset) were measured using a four-point probe method. The highest Tc-zero recorded was 97 K, which was exhibited by the
pure Tl-1212 sample. The onset critical temperature (Tc-onset) recorded was between 97 K and 105 K. The transport critical
current, Ic, all samples were found through the 1 µV/cm criterion with temperature ranging from 30 K to 77 K. The introduction

ABSTRACT
Superconductor is an element or compound that conduct current without any resistance below a certain temperature. Yttrium
Barium Copper Oxide (YBa2Cu3O7-∂) was the first high temperature superconductor (HTS) found in 1986, show it would become
superconductive at temperature warmer than liquid. Nowadays, there are many demands for superconductor in their applications.
However, YBa2Cu3O7-∂ superconductor suffers from low grain conductivity and weak links of the grains, thus resulting in disruption
of superconducting performance. This research was focusing on the effect of microstructure and phase formation of YBa2Cu3O7-∂
adding with marine waste, cephalopod bone. Cephalopod bone contains various types of elements which believe has the potential
as an alternative resource for conductor
