Four-color theorem linked to crystal's magnetic properties
An electronic bucket brigade could boost solar cell voltages
If solar cells could generate higher voltages when sunlight falls on them, they'd produce more electrical power more efficiently. For over half a century scientists have known that ferroelectrics, materials ...
New Path To Solar Energy Via Solid-State Photovoltaics
(PhysOrg.com) -- Berkeley Lab researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new path to energy production brightens the future for ...
Scientists discover rigid structure in centre of turbulence
Pioneering mathematical engineers have discovered for the first time a rigid structure which exists within the centre of turbulence, leading to hope that its chaotic movement could be controlled in the future.
Researchers take first pictures of baby nanotubes
Single-walled carbon nanotubes are loaded with desirable properties. In particular, the ability to conduct electricity at high rates of speed makes them attractive for use as nanoscale transistors. But this ...
Thin film produces new chemistry in 'nanoreactor'
Physicists of the University of Groningen and the FOM Foundation, led by professor Beatriz Noheda, have discovered a new manganese compound that is produced by tension in the crystal structure of terbium manganese oxide. ...
Less is more: Novel cellulose structure requires fewer enzymes to process biomass to fuel
(Phys.org) —Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory (LANL) and the Great ...
Changing cellulose-forming process may tap plants' biofuel potential
(Phys.org) —Changing the way a plant forms cellulose may lead to more efficient, less expensive biofuel production, according to Penn State engineers.
Plant protein shape puzzle solved by molecular 3-D model
(Phys.org) —Researchers from North Carolina State University believe they have solved a puzzle that has vexed science since plants first appeared on Earth.
Cork the key to unlocking the potential of graphene
Scientists have taken inspiration from one of the oldest natural materials to exploit the extraordinary qualities of graphene, a material set to revolutionise fields from computers and batteries to composite ...
Imaging with neutrons: Magnetic domains shown for the first time in 3-D
Although they exist in almost every magnetic material, you cannot see them: magnetic domains are microscopically small regions of uniform magnetization. Dr. Ingo Manke and his group at the Institute of Applied ...
Scientists crack code of critical bacterial defense mechanism
Scientists have combined chemistry and biology research techniques to explain how certain bacteria grow structures on their surfaces that allow them to simultaneously cause illness and protect themselves from the body's defenses.
A full-sized California-style home made of bamboo
A new type of eco-friendly residential house made of bamboo now stands in Changsha, Hunan Province, China.
Biomass analysis tool is faster, more precise
A screening tool from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) eases and greatly quickens one of the thorniest tasks in the biofuels industry: determining cell wall chemistry to find plants ...
