Well! we are moving with high pressure. May God bless AIRAPT

Researchers have discovered a metal alloy that can conduct electricity with zero resistance, or superconduct, from ambient pressure up to pressures similar to those that exist near the center of the Earth. The material, which is likely the first to show this kind of robust superconductivity, is desc...

The pressure inside a neutron star is immense. Imagine the mass of a sun-sized star packed inside an object with the width of a city. How would matter be impact...ed by these superdense conditions? LIGO’s recent discovery of a neutron star collision, along with other recent breakthroughs, has researchers hopeful an answer is in sight.

The core of a neutron star is such an extreme environment that physicists can’t agree on what happens inside. But a new space-based experiment — and a few more

Amendments to AIRAPT Constitution: the online voting is in progress. If you participated to a recent AIRAPT Conference but have not received the token to vote by email, please contact the AIRAPT Webmaster before the deadline (December 22nd, 2017, 23:59 CET) http://www.airapt.org/?q=node/12

The Constitution of the AIRAPT is available as a PDF file, linked below. This includes the modifications to the by-laws subsequently approved by the AIRAPT General Assembly in Mumbai (2011), by the AIRAPT Executive Committee in Seattle (2013), in Madrid (2015), and in Beijing (2017).

Although liquid metals are effective fluids for heat transfer, pumping them at high temperatures is limited by their corrosiveness to solid metals. A clever pump design described in Nature addresses this challenge using only ceramics. This News & Views article discusses the findings.

Hydrogen is the most abundant element in the Universe, and it experiences extreme pressures in stars and in gas giant planets. Now researchers at the Carnegie I...nstitution for Science have managed to accurately measure hydrogen's melting point at pressures up to 300 GPa (3 million times atmospheric pressure) finding results that contradict theoretical predictions, explain physicists Peter Celliers and Jon Eggert of Lawrence Livermore National Laboratory.

Measurements of the melting curve of hydrogen at unprecedentedly high pressures call for a refinement of the theories describing the material.

Congratulations to Professor Changqing Jin (Institute of Physics, Chinese Academy of Sciences), elected Chairman of the Commission for Crystallography of Materials, a permanent commission of the International Union of Crystallography. Professor Changqing Jin was Chairman of the 2017 AIRAPT Conference, which has just finished in Beijing, China.

Water and methane do mix, but at high pressure

At low pressures, the solubility of gases in liquids is governed by Henry’s law, which states that the saturated solubility of a gas in a liquid is proportional to the partial pressure of the gas. As the pressure increases, most gases depart from this ideal behavior in a sublinear fashion, leveling…

Researchers demonstrate 'diamond showers' forming in the ice giants of our solar system. Using an ultra-strong X-ray laser to simulate conditions inside the cos...mic giants, they observed the fission of hydrocarbon and the conversion of carbon into diamonds in real time. The results are published in Nature Astronomy.
