Nanotechnology for Researchers

George Smith (Oxford University):

Nano “comes from the verb which means

to seek research funding.”

Literature on Perceptions of Nanotechnology

Five Questions

Q1: What is nanotechnology?

Nanotechnology: The term

Norio Tanaguchi (1974):

‘Nano-technology’ mainly consists of the processing of separation,

consolidation, and deformation of materials by one atom or one molecule.

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

Nanotechnology: The termUS Patents and Trademarks Office (2006):

“Nanotechnology is related to research and technology development at the atomic, molecular or

macromolecular levels, in the length of scale of approximately 1-100 nanometer range in at least one

dimension; that provide a fundamental understanding of phenomena and materials at the nanoscale; and

to create and use structures, devices and systems that have novel properties and functions because of

their small and/or intermediate size.”

Nanotechnology

• pervasive

• ubiquitous

Nanotechnology

A broad and inclusive definition is needed.

Q1: What is nanotechnology?

A1:

At least 1 dimension has a length-scale

between 1 to 100 nm.

Q2: Why will nanotechnologybe pervasive and

ubiquitous?

Q2: Why will nanotechnologybe pervasive and

ubiquitous?

A2:

Because of its gigantic scope.

Q3: What is the common thread in all technoscientific

opportunities offered by nanotechnology?

A3: Nanomaterials.

Q4: What societal issues will emerge from the spread of

nanotechnology?

• Known knowns• Known unknowns• Unknown unknowns

• Known knowns• Known unknowns• Unknown unknowns

“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 Impacts

Nanoparticles may be more toxic than larger particles

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

Manufactured amounts are small, but will increase over time.

Human Health Impacts

Risk to workers and consumers

• Inhalation (Workers and consumers)

• Penetration of skin (Workers and consumers)

• Combustible nanoparticles may cause explosions (Workers)

Human Health Impacts

Life-cycle auditing of nanomaterials is essential.

US Federal funding of Environment Health & Safety Research on Nanomaterials is growing.

Current Educational Practices

Supplementary Approach

Current Educational Practices

• to identify intersecting disciplines

• to acquire necessary knowledge base

• to synthesize an acceptable accomplishment

• to assess needs for further progress

• to contextualize the accomplishment

Students must learn

End-of-semester

End-of-year

End-of-school EXPERIENCES

(JITE)

JITE Experience• Spans > 1 science/math disciplines• Single-member• Team-based• Apportionment of tasks• Deadlines• Oral/written reports

• 4 Crucial elements

• 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. 4

Dispersal 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 must learn about mathematics and sciences4. Become lifelong learners
