Reclaim even a small amount of that lost heat as electricity, and that would massively boost energy efficiency. Thermoelectric materials allow us to do just that, by coaxing a current from a temperature difference. Wrap a thermoelectric substance around your car's exhaust, and its waste heat could power the electrics. Incorporate thermoelectric elements into a refrigerator, and heat extracted from its interior could power it

Growing Issues In A Miniature World: Nanomaterial Registers In The EU - 0 views
-
"There is currently no uniform approach to nanomaterials at the EU level and no EU register. However, nanomaterials are, to a limited extent, covered by EU sector-specific regulation. For instance the Food Information Regulation, the Cosmetics Regulation, the Medical Devices Regulation and the Biocides Regulation contain specific provisions on nanomaterials. While moreover applying to substances in the nano form, the Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) does not currently contain specific provisions on nanomaterials."

New Method Used to Synthesize Cu-Based Nanocomposite - 0 views

In this research, we added silicon carbide powder of micro and nanoscales to copper by means of friction stir processing in order to reinforce its strength and resistance to surface erosion.
-
"It is possible to increase the strength base and resistance to erosion up to 3 times and 10 times respectively with respect to the material substance. It is also possible to give properties such as semi conduction or other physical properties to the desired material with regard to its application," he added, explaining about the results of the study.
Second-hand (metal) law to help combat stolen copper cable trade - 0 views

The new Act does not allow scrap metal dealers to have in their possession any apparatus which could be used for the recycling of any controlled metal or any article or substance containing any controlled metal, Bezuidenhout said at the Copper Cable Theft conference, in Johannesburg.
Conductive metal-organic frameworks - 1 views
-
Scientists from the National Institute of Standards and Technology (NIST) and Sandia National Laboratories have added something new to a family of engineered, high-tech materials called metal-organic frameworks (MOFs): the ability to conduct electricity. This breakthrough—conductive MOFs—has the potential to make these already remarkable materials even more useful, particularly for detecting gases and toxic substances.

Prof Smil’s answer is that we need to think about “rational futures of moderated energy and material use”. As he admits, though, it is hard to see any political leaders being prepared to offer their citizens less and less in the future; particularly not in emerging economies where billions are hoping to come closer to developed world lifestyles.
