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 ...
US West's power grid must be prepared for impacts of climate change
Electricity generation and distribution infrastructure in the Western United States must be "climate-proofed" to diminish the risk of future power shortages, according to research by two Arizona State University ...
Renewable energy vital for Internet lifestyles: Greenpeace
A Greenpeace report released on Tuesday charged utilities with hampering efforts to use renewable energy to power data centers needed for services hosted in the cloud.
Scientists tune X-rays with tiny mirrors
The secret of X-ray science – like so much else – is in the timing.
The random Raman laser—a new light source for the microcosmos
In modern microscope imaging techniques, lasers are used as light sources because they can deliver fast pulsed and extremely high-intensity radiation to a target, allowing for rapid image acquisition. However, ...
Compact synchrotron makes tumors visible
Soft tissue disorders like tumors are very difficult to recognize using normal X-ray machines. There is hardly any distinction between healthy tissue and tumors. Researchers at the Technische Universität ...
