Unconventional solar cell materials that are as abundant but much less costly than silicon and other semiconductors in use today could substantially reduce the cost of solar photovoltaics, according to a new study from the Energy and Resources Group and the Department of Chemistry at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory.
Before you can design the perfect nanoparticle catalyst, you first need to understand the fundamental science that governs their reactivity, say scientists from the US. And they claim to have done just that, using single molecule spectroscopy to reveal that nanocatalyst surface properties respond to changes to the concentration of reactants.
Dr. Paul Corkum, a professor in the Department of Physics at the University of Ottawa and attosecond science researcher at the National Research Council Canada (NRC), is this year's winner of Canada's most prestigious science prize.
A lot of high pressure materials can be made, but once the pressure is reduced they go back to their original form. People cannot make anything useful from those materials. But a new alloy is quenchable, meaning that the alloy persists when the pressure is gone.
Materials containing bimetallic nanoparticles are attractive in vast technological fields because of their unique catalytic, electronic, and magnetic properties. One of the most promising of the bunch is made from palladium and gold, an alloy that could be used in a wide variety of catalytic activities including the water-gas shift reaction and the oxidation of carbon dioxide - both important steps in alternative energy applications like fuel cells.
Continuing to remain at the forefront of using cutting-edge technology to meet societal needs, IIT-Madras is filing a patent on two new applications of nanotechnology for removal of dyes from waste water released from textile mills and for more efficient drug delivery in cancer treatment.
