New mass spectrometry technique studies kinetics of fast reactions
Aerogel catalyst shows promise for fuel cells
(Phys.org)—Graphene nanoribbons formed into a three-dimensional aerogel and enhanced with boron and nitrogen are excellent catalysts for fuel cells, even in comparison to platinum, according to Rice University ...
Scientists get first glimpse of a chemical bond being born
Scientists have used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to get the first glimpse of the transition state where two atoms begin to form a weak bond on the way ...
Scientists have taken a big step toward the rational design of catalysts
Most of our food, medicine, fuel, plastics and synthetic fibers wouldn't exist without catalysts, materials that open favorable pathways for chemical reactions to run forth. And yet chemists don't fully understand ...
Cheap and abundant chemical outperforms precious metals as a catalyst
A team of Caltech chemists has discovered a method for producing a group of silicon-containing organic chemicals without relying on expensive precious metal catalysts. Instead, the new technique uses as a ...
Proteins stepping on 'landmines': How they survive the immense heat they create
How do some proteins survive the extreme heat generated when they catalyze reactions that can happen as many as a million times per second? Work by researchers from Indiana University-Purdue University Indianapolis ...
Scientists re-create what may be life's first spark
Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth.
World's first artificial enzymes created using synthetic biology
(Phys.org)—Medical Research Council (MRC) scientists have created the world's first enzymes made from artificial genetic material. Their synthetic enzymes, which are made from molecules that do not occur ...
Cheap hybrid outperforms rare metal as fuel-cell catalyst
(Phys.org) —Graphene quantum dots created at Rice University grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, ...
Water in the solar system predates the Sun
Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth's water is key to understanding how life-fostering ...
Gold's unexpected oxidation activity: Decoding the role of water in gold nanocatalysis
Researchers from the University of Houston and Trinity University have for the first time provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide.
