suggested frameworks
Lloyd L. Tran President International
Association of Nanotechnology
2

Why do we need a roadmap?
  • To find the best route
  • To identify avoid obstacles and detours
  • To optimize resources
  • To collaborate with partners
  • To maximize return of investment
  • To communicate stakeholders

3
Important factors in developing a roadmap
  • What is the industry we are in?
  • i.e. semiconductor, chemical, biotechnology,
    aerospace
  • What is the use of it?
  • i.e. A better computer chip, method to treat
    diseases, stronger material for aerospace
    applications
  • What are the obstacles?
  • i.e. Quantum effects at nanoscale, unknown
    toxicity, public acceptance
  • What is the key strategy?
  • i.e. focusing on the beneficial applications
    of nanotechnology
  • What are the resources?
  • i.e. government funding, private investment
  • What is the time frame?
  • i.e. a 5- 10 year plan

    Consideration

Scientific Development Factors
  • Multi-disciplinary nature of nanoscience and
    nanotechnology
  • More funding are needed to realize the full
    potential of nanoscience
  • Limited resources are available for
    nano-manufacturing production
  • Need to focus on a certain list of priority of
    research topics, rather than
  • scattered resources every where.
  • Need to develop internationally accepted
    nomenclature
  • Need to develop internationally accepted
    standards for research methodology
  • and quality control and quality assurance.
  • Need to collaborate internationally, while
    strengthen expertise locally

Economic Factors
  • Small technology-based entrepreneurial
    companies as a source of
  • innovation and generator of jobs.
  • Investors shy away from applications with
    lengthy time periods
  • between R D and market penetration.
  • Small companies at risk through the valley
    of death in funding and
  • the period nexus between public policy and
    industry realities.
  • Public/Private funding i.e. Incubator facility
    and seed capital needed to
  • nurture start-up companies with promising
    technology
  • Building an accessible labor pool of
    nanotechnologists and workforce in
  • nanotechnology to create jobs and foster
    economic growth.

Public Relations Factors
  • Limited public awareness of nature and
    potential of nanotechnology
  • Public funding to date focused on R D- Ratio
    of R D to successful
  • product development is low
  • Limited resources focusing on
    nano-manufacturing Commercialization's
  • Government has not yet fully recognized
    barriers that could be assisted
  • through increased public support
  • Government support for nanotechnology
    innovation, i.e. FDA stamp of
  • approval that a discrete nanomaterial is
    approved for market.
  • Product liability guidelines for
    nanotechnology to clarify ambiguity
  • surrounding market opportunities for
    nanotechnology products

  • Societal
  • Environmental
  • Health Safety

Public Engagement ?
  • Nomenclature

9
Challenges in developing international
nomenclature/ standards
  • Communication across multi-disciplines
  • National and international geo-political
    differences
  • Intellectual Property protection
  • Confidential business information
  • Lack of funding for this long term endeavor
  • Concern about potential government regulations
    and public policy

International Association of Nanotechnology by
Lloyd L. Tran
10
Why International Standards are needed ?
  • The Standard Project will develop
    interoperability specifications for
    nanomaterials, devices and nanoscale structures
    and systems.
  • To set international standards for testing
    methods and processes so data is reported
    uniformly and results can be compared and
    verified
  • This will help researchers, designers,
    manufacturers and suppliers as well as customers
    to communicate effectively and harmonize best
    practices worldwide.
  • To optimize the manufacturing processes while
    ensure the trust and confidence of customers and
    public at large
  • Without standards the emerging field cannot
    grow to become an major industry.

International nomenclature and standards in
Nanotechnology are urgently needed for
  • Research laboratory
  • Publication
  • Patent Protection
  • Communication
  • Clinical study
  • Manufacturing
  • Commercialization

  • Top-down
  • Wet/wet, wet/dry, dry/dry
  • Nano-scale hybrid materials
  • Taxonomy of carbon nanostructured
  • carbon black, diesel exhaust, filtration carbon,
    C60, fullerene, single-wall carbon nanotubes,
    multiwall carbon nanotubes

    characteristics of carbon nanotubes
  • IUPAC and CAS have had some nomenclature
    frameworks for fullerene

    initiated a Nanotech panel
  • ASTM and ASME has recently begun metrology
    effort
  • ISO has begun development of international
    standards in nanotechnology

Toxic Substances Control Act 15 U.S.C. s/s 2601
et seq. (1976)
  • The Toxic Substances Control Act (TSCA) of
    1976 was enacted by Congress to give EPA the
    ability to track the 75,000 industrial chemicals
    currently produced or imported into the United
    States.
  • EPA repeatedly screens these chemicals and can
    require reporting or testing of those that may
    pose an environmental or human-health hazard.
  • EPA can ban the manufacture and import of
    those chemicals that pose an unreasonable risk.
