  • Nanotechnology – what is it? are there hazards?

    This is the first of a series articles on the emerging field of Nanotechnology. What is it? In short – small! Very small! Very, very small! Nanotechnology comes from the prefix Nano which, in English, means 1/billionth, just as micro means 1/millionth. So Nanotechnology involves 2 things: 1) extremely small man-made materials – some even as small as 1 atom thick, ...

  • Nanotechnology as a basis for the vascular treatment of atherosclerosis

    It is now accepted that during the early stages of development of coronary and carotid atherosclerotic plaques, activation of vasa vasorum (VV) at specific sites in the adventitia initiates their proliferation or 'angiogenesis', and migration through the media into the intima of unstable developing lesions. Plaques regions containing these immature vessels tend to exhibit increased inflammation ...

  • Diversity of entrepreneurs and diversity of clusters in nanotechnologies

    The objective of the present contribution is to characterise the nature and role of entrepreneurs in nanotechnologies. The analysis is conducted with regards to specific contexts of emergence of nanotechnologies that we characterise by a two-stage process of development. We show that the risk-taking entrepreneur who transforms externalities into new activities by combining existing resources is ...

  • Dangers of nanotechnology: potential fire concerns and safety frameworks

    The benefits of engineering of functional systems at the nanometre-scale as one of the key technologies of the 21st century almost always imply grave risks. The increasing speed of nanotechnology commercialisation and development has apparently outstripped the study of health and safety data. A potential hazard of nanopowders that appears to have received little attention so far is their ...

  • Applying a precautionary risk management strategy for regulation of nanotechnology

    Nanotechnology promises a multiplicity of benefits to society. At the same time it has become a focus of debate regarding potential health and other associated risks. Rejection of new nanotechnology innovations could result in loss of trust in regulators, a phenomenon observed previously with nuclear and genetically altered food crop technologies. Due to this uncertainty a precautionary approach ...

  • The Adequacy of FIFRA to Regulate Nanotechnology-Based Pesticides

    As applied to pesticides, the new and developing area of nanotechnology has the potential to bring real benefits, but also regulatory challenges. Reportedly, it has already begun changing the nature of some pesticides. There are consumer products on the market today using engineered nanoparticles of active ingredients such as silver to achieve antimicrobial effects, and many more are likely. Even ...

  • RAND Corporation Assesses NIOSH Nanotechnology Research Center

    The National Institute for Occupational Safety and Health (NIOSH) posted a RAND Corporation (RAND) report entitled Nanomaterial Safety in the Workplace: Pilot Project for Assessing the Impact of the NIOSH Nanotechnology Research Center. See http://www.cdc.gov/niosh/topics/nanotech/files/rand_rr1108.pdf In August 2014, NIOSH asked RAND to ...

  • The MacDiarmid Institute for Advanced Materials and Nanotechnology: a New Zealand Centre of Research Excellence

    The MacDiarmid Institute is a New Zealand Centre of Research Excellence, established in 2002 to draw together some of the disparate activities in these fields. It is named after Nobel prize-winner, Alan MacDiarmid, a New Zealander who brought his scientific insights and vision to the Institute during the first five years of its existence. We review the brief history of the Institute here, putting ...

  • Nanotechnology: a successive industrial revolution of Schumpeter's long wave theory

    This paper is concerned with the strategies on research management and technology policies of nanotechnology. Nanotechnology is now a science and technology (S&T) priority area for many Asian countries with governments making efforts to put the results of nanotechnology development to commercialisation. The national policy for nanotechnology is to change the existing technology system and bring ...

  • Active emitters based on nanostructured Si

    The present paper deals with the use of Si nanoclusters as efficient sensitisers for Er and Nd rare earth ions or as active emitters in Si/SiO2 Fabry-Perot microcavities. The films have been fabricated using the reactive magnetron sputtering of a silica target. The energy transfer efficiency from Si-nc towards Er ions has been studied as a function of the fabrication parameters (hydrogen rate, ...
