Industry analyst firm NanoMarkets has just issued its latest report on the thin-film battery market, projecting that the value of products containing thin-film batteries will reach approximately $14 billion by 2016.
MIT researchers have found a new way to predict which materials will perform best as catalysts for oxygen reduction, a core process in metal air batteries and fuel cells, opening up the possibility of faster and more effective development of new high-efficiency, low-cost energy-storage technologies.
It doesn’t look like a leaf, but the photosynthesis imitator being developed by teams at MIT would do much the same thing. Right now, it consists of a glass container full of water, with a catalyst-equipped solar cell inside on a divider between two sections. When exposed to the sun, the electrified catalysts produce two streams of bubbles — hydrogen on one side, oxygen on the other. When recombined these two elements create electricity; MIT is still working on the hydrogen side.
Researchers now understand more about why platinum is so efficient at producing power in hydrogen fuel cells.
This economics of electric vehicles was highlighted this morning’s R&D Daily , and the major finding was that EV batteries need to get significantly cheaper (and better) before consumers will buy them in large numbers. That future might be up to researchers like the EV team at Berkeley Lab, which is trying to improve the lithium-ion battery.
A new "organocatalyst" developed at Oregon State Univ. is now available for commercial use. Produced by an Albany, Ore., pharmaceutical company, it should make new drug development around the world less costly, more efficient, and more environmentally friendly.
A team of scientists in Italy and South Korea have built a new type of lithium-ion based spinel cathode material that, when used in a battery with a tin-carbon anode, have been shown to supply high rate charge and discharge cycles and energy density on the order of 170 Wh/kg -1 . This performance indicates a suitable use in electric vehicles
Researchers in Denmark and at Stanford’s National Accelerator Lab have created a device to harvest the energy from part of the solar spectrum and have it to power the conversion of single hydrogen ions into hydrogen gas. They were able to do so without the use of expensive platinum catalysts, instead finding a way to use molybdenum sulfide in conjunction with a chemical solar cell.
Associate Professor Sergiu M. Gorun is leading a research team to develop a biologically-inspired catalyst, an active yet inert material. The work is based on organic catalytic framework made sturdy by the replacement of carbon-hydrogen bonds with a combination of aromatic and aliphatic carbon-fluorine bonds.
A research team from the UCLA Henry Samueli School of Engineering and Applied Science has proposed and demonstrated a new approach to producing nanocrystals with predictable shapes by utilizing surfactants, biomolecules that can bind selectively to certain facets of the crystals' exposed surfaces.
Scientists anticipate a move away from centuries of caustic, hazardous aqueous-based battery cells, and the future could include the latest invention from scientists at NRL. Their new battery operates on hydrogen sulphate, an ionic liquid that acts as an electrolyte and can mimic alkaline batteries with discharge voltages up to 1.8 V.
Scientists have discovered a method to control the gas-phase selective catalytic combustion of methane, so finely that if done at room temperature the reaction produces ethylene, while at lower temperatures it yields formaldehyde. The process involves using gold dimer cations as catalysts.
Nanocrystal and nano-catalyst design have become increasingly important as conventional metal catalysts have shown themselves to have too many limitations for next generation energy storage and conversion devices. Berkeley Lab’s latest crystal design multiply catalytic reaction sites significantly.
A new catalytic chemical method for the synthesis of a large and important class of carbon-carbon double bonds has been developed by scientists from Boston College and MIT, the team reports in the journal Nature . The findings expand the versatility of a set of metal-based catalysts discovered only three years ago by the researchers.
L. Keith Woo of Iowa State Univ. and the Ames Laboratory is looking for cleaner, greener, and cheaper catalysts. Woo and his research group are turning to biology for some ideas. And they're developing high-throughput approaches to quickly test a reaction using up to a hundred trillion different catalysts.
Researchers at Northwestern Univ.'s Institute for Catalysis in Energy Processing have discovered a new strategy for fabricating metal nanoparticles in catalysts that promises to enhance the selectivity and yield for a wide range of structure-sensitive catalytic reactions.
A new combination of nanoparticles and graphene results in a more durable catalytic material for fuel cells. The catalytic material is not only hardier but more chemically active as well. The researchers are confident the results will help improve fuel cell design.
A little disorder goes a long way, especially when it comes to harnessing the sun’s energy. Scientists from the Lawrence Berkeley National Laboratory jumbled the atomic structure of the surface layer of titanium dioxide nanocrystals, creating a catalyst that is both long lasting and more efficient than most materials in using the sun’s energy to extract hydrogen from water.
Researchers from the Cardiff Univ. School of Chemistry are opening up a new way of using hydrocarbon feedstocks to make a range of valuable products.
Michael Kessler, an Iowa State Univ. associate professor of materials science and engineering and an associate of the U.S. Department of Energy's Ames Laboratory, has worked with polymers that repair themselves when they crack. And he's worked with polymers made from vegetable oils. Now he's working to combine the two technologies. Kessler is researching and developing biorenewable polymers capable of healing themselves as they degrade and crack.
