Seismic detection of post-perovskite inside the Earth [PDF]
, 2015 Since 2004, we have known that perovskite, the most abundant mineral in the lower mantle, has the capacity to transform to a denser structure, postperovskite, if subjected to sufficiently high temperature and pressure.

Advanced Physics Research, EarlyView.The defect diamond‐like material Hg3P2S8 (HPS) is systematically investigated using first‐principles methods to reveal the interplay between highly distorted HgS4 and rigid PS4 units. The HPS material exhibits a strong anisotropic second‐harmonic generation (SHG) response, favorable optical properties, and low thermal conductivity, highlighting its ...

Extraterrestrial seismology [PDF]
, 2015 Seismology is a highly effective tool for investigating the internal structure of the Earth. Similar techniques have also successfully been used to study other planetary bodies (planetary seismology), the Sun (helioseismology), and other stars ...

A high-precision borehole gravimeter
Geodesy and Geodynamics, 2011 The paper describes the working principle and structure of a newly designed high-precision (micro-gal) gravimeter, which is basically a vertically suspending spring-weight system, using a highly sensitive capacitance sensor of movement in a controlled ...
