Thermodynamic analysis reveals large overlooked role of oil and other energy sources in the economy
Electric vehicles could stabilize large disturbances in power grid
Innovative light therapy reaches deep tumors
Light long has been used to treat cancer. But phototherapy is only effective where light easily can reach, limiting its use to cancers of the skin and in areas accessible with an endoscope, such as the gastrointestinal ...
Perovskite solar cell reaches record efficiency
Adding leap second this year expected to cause Internet problems
Good vibrations give electrons excitations that rock an insulator to go metallic
For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize-winning ...
Breakthrough allows researchers to watch molecules 'wiggle'
A new crystallographic technique developed at the University of Leeds is set to transform scientists' ability to observe how molecules work.
Improved liquid battery: Longer-lasting materials could enable batteries that make renewables more competitive
Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants.
When an exciton acts like a hole
(Phys.org) —When is an electron hole like a quasiparticle (QP)? More specifically, what happens when a single electron hole is doped into a two-dimensional quantum antiferromagnet? Quasiparticle phenomena ...
Earth-crushing pressure? This electron spin doesn't care
(Phys.org) —To fully understand something, it is often instructive to view it at its extremes. How do materials behave when their bits are forced much closer together than is comfortable? How do electrons ...
Scientists describe protein pumps that allow bacteria to resist drugs
Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structures of two proteins they believe pump antibiotics from bacteria, allowing the bacteria to resist ...
Mixing up a batch of stronger metals
Just as a delicate balance of ingredients determines the tastiness of a cookie or cake, the specific ratio of metals in an alloy determines desirable qualities of the new metal, such as improved strength ...
X-ray ptychography, fluorescence microscopy combo sheds new light on trace elements
Scientists have developed a new approach that combines ptychographic X-ray imaging and fluorescence microscopy to study the important role trace elements play in biological functions on hydrated cells.
