Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun's light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering and Applied Science has shown that the force of light indeed can be harnessed to drive machines - when the process is scaled to nano-proportions.
Scientists from leading European research institutions in the field of solar-to-fuel energy conversion call for unified action and substantial support for novel clean fuel technologies as well as a paradigm change in Europe?s current energy policy.
A process for producing photo-catalytic, self-cleaning coatings has been developed by scientists at Singapore's A*STAR (Agency for Science, Technology and Research), and licensed to Haruna (S) Pte Ltd.
In addition to its iridescent beauty, mother of pearl, or nacre, the inner lining of the shells of abalone, mussels and certain other mollusks, is also renowned for an amazing strength and toughness that has been a long-standing mystery. Now, scientists have brought to light a new aspect of nacre?s nanostructural architecture using the polarized x-ray beams and nanoscale imaging capabilities of the Advanced Light Source (ALS), a national synchrotron facility at the Lawrence Berkeley National Laboratory.
A new 'barcode chip' developed by researchers at the California Institute of Technology (Caltech) promises to revolutionize diagnostic medical testing. In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.
Researchers working at the National Institute of Standards and Technology (NIST) have demonstrated for the first time the existence of a key magnetic - as opposed to electronic - property of specially built semiconductor devices.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated their ability to measure relatively low levels of stress or strain in regions of a semiconductor device as small as 10 nanometers across.
You never know where basic research may lead. For decades materials scientists have been experimenting with a corkscrew-like polymer structure called a gyroid. Now an international team of researchers has shown that the gyroid structure can be used to self-assemble a low-cost photovoltaic cell.
Rice University nanophotonics pioneer Naomi Halas has been named a National Security Science and Engineering Faculty Fellow (NSSEFF) by the Department of Defense. Halas is one of just six fellows chosen from more than 650 nominees this year for the prestigious program.
The Society for the Study of Nanoscience and Emerging Technologies (S-NET) is poised to become an international organization to promote open intellectual exchange towards the advancement of knowledge and understanding of nanotechnologies in society.
