Building molecular engine: Researchers induce uniform oscillation from random noise of single hydrogen molecule
Stealing nature's photosynthetic secrets
(Phys.org)—The prospect of creating clean, renewable hydrogen fuel is closer than ever after a breakthrough in our understanding of photosynthesis.
Nanocrystals and nickel catalyst substantially improve light-based hydrogen production
Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal ...
A computational approach to predicting the structure of nano-alloy catalysts revealed
Nanoparticles can be potent catalysts. Bimetallic nano-alloys of platinum and palladium, for example, can help to generate hydrogen fuel by promoting the electrochemical breakdown of water. Identifying the ...
Impurity atoms impart remarkable control over water-splitting reactions on insulator surfaces
Ultra-thin inorganic oxide films are set to play vital roles in future catalytic systems, according to findings from Jaehoon Jung and Yousoo Kim at RIKEN's Advanced Science Institute in Wako and two colleagues ...
'Ordered' catalyst boosts fuel cell output at lower cost
(Phys.org)—Fuel cells, which convert fuel directly into electricity without burning it, promise a less polluted future where cars run on pure hydrogen and exhaust nothing but water vapor. But the catalysts ...
Near-atomically flat silicon could help pave the way to new chemical sensors
Silicon is the workhorse of the electronics industry, serving as the base material for the tiny transistors that make it possible for digital clocks to tick and computers to calculate. Now scientists have succeeded in creating ...
By measuring lithium, researchers study star structure
During its nuclear fusion processes, a burning star does not make the element lithium. Rather, over time, stars consume their lithium supply that was originally created during the Big Bang that gave birth to our universe.
Optical tweezers and sub-nanoscale precision: Following the process—and the consequence—of RNA folding
(Phys.org)—In a soundproofed, vibration-stabilized, temperature-controlled room, Stanford biophysicist Steven Block was watching a very small origami project.
Chemists develop new technique for nanostructure assembly
A team of researchers from the University of Florida department of chemistry has developed a new technique for growing new materials from nanorods.
Testing Mars and Moon soil for sheltering astronauts from radiation
(Phys.org)—Humans venturing beyond Earth orbit deeper into space face increased exposure to cosmic radiation, so ESA has teamed with Germany's GSI particle accelerator to test potential shielding for astronauts, ...
Graphene: A patterned template for molecular packing
Graphene's versatile electronic, chemical and mechanical properties have placed it center stage in physical sciences research, with attention currently focused on its potential applications. Computational ...
Synthetic liver enzyme could result in more effective drugs with fewer side effects
(Phys.org)—Medicines could be made to have fewer side effects and work in smaller doses with the help of a new technique that makes drug molecules more resistant to breakdown by the human liver.
Introduction of fluorine atoms into organic molecules could have applications for synthesis of pharmaceuticals
Despite its small size, the fluorine atom has had a vast impact on the pharmaceutical industry. More often than not, introducing fluorine to a drug molecule improves the drug's biological activity, earning ...
