Core electron topologies in chemical bonding

YNU researchers have solved the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides reveals a qualitative difference in the ...

Extreme pressure causes osmium to change state of matter

Using metallic osmium (Os) in experimentation, an international group of researchers have demonstrated that ultra-high pressures cause core electrons to interplay, which results in experimentally observed anomalies in the ...

Record high pressure squeezes secrets out of osmium

An international team of scientists led by the University of Bayreuth and with participation of DESY has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated ...

New technique for exploring structural dynamics of nanoworld

A new technique for visualizing the rapidly changing electronic structures of atomic-scale materials as they twist, tumble and traipse across the nanoworld is taking shape at the California Institute of Technology. There, ...

Long-sought magnetic mechanism observed in exotic hybrid materials

Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological insulators—hybrid ...

Missing link in metal physics explains Earth's magnetic field

Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means ...
