Researchers produce ultra-light aerogel

A research team headed by Professor Gao Chao have developed ultra-light aerogel – it breaks the record of the world's lightest material with surprising flexibility and oil-absorption. This progress is published in the "Research ...

Low density of Earth's core due to oxygen and silicon impurities

During accretion and differentiation of the Earth, chemical interactions in a silicate magma ocean and liquid iron drove silicon and oxygen impurities into what went on to become the liquid outer core. Contrasting with previous ...

Researchers demonstrate laser cooling of a semiconductor

(Phys.org)—A team of physicists working in Singapore has, for the first time, demonstrated the cooling of a semiconductor using a laser. To achieve this feat, the team, as they describe in their paper published in the journal ...

Miniaturized sensors hold up under pressure

Applications as diverse as oil-well drilling and robot-driven surgery are driving demand for improved micro-electromechanical system (MEMS) pressure sensors. As they are made smaller, however, simultaneously achieving high ...
