Article: Dark side of nanotechnology |
|
Malaysia aspires to be in the top 10 of nanotechnology nations that will create new sources of economic growth for future generations. But there are dangers that could have serious repercussions in how we work and live.
ON SEPT 23, I was invited to attend a workshop on the National Nanotechnology Strategy in Kuala Lumpur. The title piqued my interest because it was relevant to my PhD research areas on the Development and Characterisation of Nanocomposites under Polymer Engineering as well as on Islamic World Views on Science and Technology under Islamic Philosophy.
I hope I would be able to contribute some ideas for the development of nanotechnology in Malaysia.
The paper “Nanotechnology Made In Malaysia: From One Small Part to One Big Success” entails the national strategic policy and support to be given to the various sectors as market players...

Nanoparticles and their size may not be big issues |
|
If you've ever eaten from silverware or worn copper jewelry, you've been in a perfect storm in which nanoparticles were dropped into the environment, say scientists at the University of Oregon. Since the emergence of nanotechnology, researchers, regulators and the public have been concerned that the potential toxicity of nano-sized products might threaten human health by way of environmental exposure.
Now, with the help of high-powered transmission electron microscopes, chemists captured never-before-seen views of miniscule metal nanoparticles naturally being created by silver articles such as wire, jewelry and eating utensils in contact with other surfaces. It turns out, researchers say, nanoparticles have been in contact with humans for a long, long time.
The research -- detailed in a paper placed online in advance of regular publication in the American Chemistry Society's journal ACS Nano – focused on understanding the dynamic behavior of silver nanoparticles on surfaces when exposed to a variety of environmental conditions.

Using nanocellulose to create novel composite materials |
|
|
 |
For some time now nanocellulose has been at the focus of a good deal of industrial and scientific interest as a novel biomaterial. Potential applications range from the creation of new kinds of commercially useful materials and uses in medical technology all the way to the food and pharmaceutical industries. Empa researchers have now developed a manufacturing process for nanocellulose powder, the raw material for creating polymer composites which can be used, for example, in lightweight structures for the car industry or as membrane and filter material for biomedicinal applications.

European Strategy for nanometrology published by the Co-Nanomet project |
|
The European Commission's FP7 NMP CSA Co-Nanomet project has recently completed its tasks and published an important European Strategy into the requirements for nanometrology up to the year 2020. The consortium of world leading National Measurement Institutes (NMI’s), Universities and key networks around Europe have worked for over 2 years and consulted many different organisations and held several workshops. The outputs from these activities are published for viewing by the community.
