Mountain of electrical waste reaches new peak
A record amount of electrical and electronic waste hit the rubbish tips in 2014, with the biggest per-capita tallies in countries that pride themselves on environmental consciousness, a report said Sunday.
Scientists move closer to 'two for one deal' on solar cell efficiency
The underlying mechanism behind an enigmatic process called "singlet exciton fission", which could enable the development of significantly more powerful solar cells, has been identified by scientists in a new study.
How secretaries of state handle classified information
Former Secretary of State Hillary Rodham Clinton says she never sent classified information through her private email account while she served as America's top diplomat, a claim that has been met with skepticism.
New imaging technique finds formation of aluminum alloys to blame for next-gen battery failures
Researchers working at the National Institute of Standards and Technology (NIST), the University of Maryland, and Sandia National Laboratories, have for the first time imaged the inner workings of experimental ...
Losing 1 electron switches magnetism on in dichromium
The scientists used the unique Nanocluster Trap experimental station at the BESSY II synchrotron radiation source at Helmholtz-Zentrum Berlin and published their results in the Journal Angewandte Chemie.
Red light goes green: Metal-free organic sensitizers portend significant advance in artificial photosynthesis
Sony steps up in wearable space with SmartEyeglass
Sony on Tuesday began taking orders for SmartEyeglass Internet-linked eyewear, moving ahead in the market as Google steps back to revise its Glass strategy.
Probing electron behaviour at the tips of nanocones
One of the ways of improving electrons manipulation is though better control over one of their inner characteristics, called spin. This approach is the object of an entire field of study, known as spintronics. Now, Richard ...
Topological protection in mechanical metamaterials
Researchers at Leiden University, the Netherlands, showed that certain crystal defects in mechanical metamaterials can harbour topologically protected motions. These mechanical states are analogues of protected ...
First direct evidence that a mysterious phase of matter competes with high-temperature superconductivity
(Phys.org)—Scientists have found the first direct evidence that a mysterious phase of matter known as the "pseudogap" competes with high-temperature superconductivity, robbing it of electrons that otherwise ...
Electronic switches on the molecular scale
A molecular electronic switch is a junction created from individual molecules that can alternate between two or more stable states, making the switch act as a conductor or an insulator. These switches show ...
Magnetic fields and lasers elicit graphene secret
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have studied the dynamics of electrons from the "wonder material" graphene in a magnetic field for the first time. This led to the discovery of ...
Judge approves $450 mn deal in Apple ebook suit
A US judge signed off on Apple's $450 million legal deal to compensate consumers harmed by an illegal price-fixing conspiracy for electronic books.
UO-industry collaboration points to improved nanomaterials
A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of University of Oregon and industry researchers.
