Earth's inner core may be oxygen-rich

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it's still unknown whether oxygen is present (and in which form it may exist) in the inner core, which is composed of almost ...

Under pressure: Solid matter takes on new behavior

Investigating how solid matter behaves at enormous pressures, such as those found in the deep interiors of giant planets, is a great experimental challenge. To help address that challenge, Lawrence Livermore National Laboratory ...

Argon found in air of ancient atmosphere

On the massive sheets of ice that stretch across Greenland and Antarctica, the temperature is so low that not even the summer sun can melt the snow deposited onto them. As the snow accumulates without melting and settles ...

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, ...
