An engineering team has discovered some of graphene oxide's important properties that can improve sodium- and lithium-ion flexible batteries.
Glimpsing pathway of sunlight to electricity
Thu, 18 Dec 2014 15:45:48 EST
Four pulses of laser light on nanoparticle photocells in a spectroscopy experiment has opened a window on how captured sunlight can be converted into electricity. The work, which potentially could inspire devices with improved efficiency in solar energy conversion, was performed on photocells that used lead-sulfide quantum dots as photoactive semiconductor material.
Study fuels hope for natural gas cars: Metal organic framework candidates for methane storage identified
Thu, 18 Dec 2014 13:19:33 EST
Cars that run on natural gas are touted as efficient and environmentally friendly, but getting enough gas onboard to make them practical is a hurdle. A new study promises to help. Researchers have calculated the best candidates among possible metal organic frameworks to store natural gas for cars.
New conversion process turns biomass 'waste' into lucrative chemical products
Wed, 17 Dec 2014 15:40:23 EST
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.
Scientists open new frontier of vast chemical 'space': As proof-of-principle, the team makes dozens of new chemical entities
Wed, 17 Dec 2014 13:15:54 EST
Chemists have invented a powerful method for joining complex organic molecules that is extraordinarily robust and can be used to make pharmaceuticals, fabrics, dyes, plastics and other materials previously inaccessible to chemists.
