X-rays capture electron 'dance'
(Phys.org)—The way electrons move within and between molecules, transferring energy as they go, plays an important role in many chemical and biological processes, such as the conversion of sunlight to energy ...
Pink diamond 'behaviour' solved but colour still a mystery
UWA scientists have explained the photochromic behaviour of the pink diamond in an attempt to uncover why they possess their pink colouration.
Odorant shape and vibration likely lead to olfaction satisfaction
(Phys.org)—A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules.
Mother nature as a wire manufacturer: Scientists see how microbe directs electrons
(Phys.org) -- For the first time, each step an electron takes as it moves along a "wire" from a microbe's interior to the outside world is known, thanks to modeling by University College London and Pacific ...
Shedding light on nature's nanoscale control of solar energy
Nature's process for storing solar energy occurs in light-absorbing protein complexes called photosynthetic reaction centers (RCs). Across billions of years of evolution, Nature has retained a common light-absorbing ...
Genome-scale model of cyanobacterium developed
(Phys.org) -- In an important step toward engineering bacteria to produce biofuel, scientists have developed one of the first global models for the nitrogen-fixing photosynthetic cyanobacterium Cyanothece ...
Sulfur in every pore: Improved batteries with carbon nanoparticles
From smartphones to e-bikes, the number of mobile electronic devices is steadily growing around the world. As a result, there is an increased need for batteries that are small and light, yet powerful. As the ...
Artificially structured metamaterials may boost wireless power transfer
Scientists calculate that a "perfect lens," a slab of artificial material engineered to focus electromagnetic fields in ways that natural materials can't, may increase the efficiency of some wireless power transfer systems.
Fluorescent probes increase understanding of bacterium's electron transfer
(PhysOrg.com) -- When it comes to transporting a cell's valuable electrons, the metal-reducing microbe Shewanella oneidensis only trusts stable, mature proteins, according to scientists at Pacific Northwest ...
Researchers create terahertz invisibility cloak
Researchers at Northwestern University have created a new kind of cloaking material that can render objects invisible in the terahertz range.
Raising the bar for biomolecular modeling
Researchers at the University of Calgary found that amino acid residues form a type of barrier to help in the process of electron transfer between proteins.
More Proof of Outer Membrane Cytochrome Role in Electron Transfer
(PhysOrg.com) -- Another step toward improving understanding of electron exchange between microbes and minerals has been documented in the January 2010 issue of Geobiology. Bacteria such as the metal-reducing Shewan ...
