Chemists report promising advance in fuel-cell technology

Chemists report promising advance in fuel-cell technology: "In a new study, chemists at Brown University report a promising advance. They have created a unique core and shell nanoparticle that uses far less platinum yet performs more efficiently and lasts longer than commercially available pure-platinum catalysts at the cathode end of fuel-cell reactions."

Observations: What happens when coal is gone?

Observations: What happens when coal is gone?: "In two centuries, people will still want to drive cars, fly in airplanes and have lighting in their houses. “Everybody I know thinks there will be big price increases with the end of easy oil and there’ll be a struggle over the resources,” he said Monday. The young scientists in the audience “need to figure out how to keep that struggle from turning into a hot war.”"

Highly Efficient Solar Cells Could Result from Quantum Dot Research | Renewable Energy World

Highly Efficient Solar Cells Could Result from Quantum Dot Research | Renewable Energy World: "Tesax, United States -- Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on semiconductor nanocrystals, or quantum dots, led by chemist Xiaoyang Zhu at The University of Texas at Austin."

Green machine: Cars could run on sunlight and CO2 - tech - 02 June 2010 - New Scientist

Green machine: Cars could run on sunlight and CO2 - tech - 02 June 2010 - New Scientist: "Experimental solar-powered reactors have shown they can create the building blocks for synthetic liquid fuels. They've got a way to go, but these projects could take a big chunk out of net carbon dioxide emissions without the need for major changes to either vehicles or refuelling infrastructure."

Solar panels could produce electricity at the same price as coal- and natural gas-burning power plants by the end of this decade if countries direct resources at this rapidly advancing corner of the energy industry, according to the Paris-based International Energy Agency."

A Fast Soluble Carbon-Free Molecular Water Oxidation Catalyst Based on Abundant Metals -- Yin et al. 328 (5976): 342 -- Science

A Fast Soluble Carbon-Free Molecular Water Oxidation Catalyst Based on Abundant Metals -- Yin et al. 328 (5976): 342 -- Science: "We report that the complex [Co4(H2O)2(PW9O34)2]10–, comprising a Co4O4 core stabilized by oxidatively resistant polytungstate ligands, is a hydrolytically and oxidatively stable homogeneous water oxidation catalyst that self-assembles in water from salts of earth-abundant elements (Co, W, and P). With [Ru(bpy)3]3+ (bpy is 2,2'-bipyridine) as the oxidant."
