Nanotechnology: The term

Norio Norio Tanaguchi Tanaguchi (1974)(1974)::

‘Nano-technology’ mainly consists of theprocessing of separation, consolidation, anddeformation of materials by one atom or onemolecule.

N. Taniguchi, On the Basic Concept of 'Nano-Technology', Proc. Intl. Conf. Prod. Eng. Tokyo, Part II, JapanSociety of Precision Engineering, 1974.

Nanotechnology: The termUS Patents and Trademarks OfficeUS Patents and Trademarks Office(2006)(2006)::“Nanotechnology is related to research and technologydevelopment at the atomic, molecular or macromolecularlevels, in the length of scale of approximately 1-100nanometer range in at least one dimension; that provide afundamental understanding of phenomena and materials atthe nanoscale; and to create and use structures, devices andsystems that have novel properties and functions because oftheir small and/or intermediate size.”

Nanotechnology: The term

Royal Society (2004)Royal Society (2004):: 0.2-100 nm

“Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don't know we don't know.” - Donald Rumsfeld (12 Feb 2002)

Health ImpactsNanoparticles may be more toxic than larger particles

• High surface area• Enhanced chemical reactivity• Easier penetration of cells

Manufactured amounts are small, but will increase overtime.

Human Health Impacts

Risk to workers and consumers

• Inhalation (Workers and consumers)

• Penetration of skin (Workers and consumers)

• Combustible nanoparticles may causeexplosions (Workers)

Human Health Impacts

Life-cycle auditing of nanomaterials is essential.

• Crucial Element No. 1Not all information be supplied to students

Students will• search school books• search extracurricular books• search the web• interview practitioners• undertake site visits

• Crucial Element No. 2Introspection and reflection by students

Students will• keep a journal of activities and ideas• prepare a statement of personal growth

• Crucial Element No. 3Socioethical contextualization

Students will reflect on relevance of projects to• their political unit and culture• the world• ecology, sustainability & diversity

• Crucial Element No. 4Dispersal of acquired knowledge

Students will• create project websites• write for newspapers and magazines• participate in local, provincial and national conferences

Teaching staffs’ responsibilities:1. Form interdisciplinary teams to guide

JITE experiences2. Mathematics and sciences staffs must

learn about humanities and social sciences

3. Humanities & social sciences staffs mustlearn about mathematics and sciences

4. Become lifelong learners
