The well-known expansion of water on cooling below 277 K is one of several peculiar properties that could signal a second critical point near 220 K and 0.1 GPa in pressure, deep in the supercooled ...

Recently, a research group led by Prof. WANG Xianlong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, successfully synthesized high-energy-density materials cubic ...

Gas density is frequently estimated indirectly by gas pressure sensors. Because the pressure in a tightly sealed compartment fluctuates greatly with temperature, such systems require temperature ...

Using the large synchrotron radiation facility SPring-8 in Japan, a collaboration of researchers from Kumamoto University, the University of Tokyo, and others from Japan and France have precisely ...

The petroleum industry uses solids-free brines for completion and work over fluids. Operators must use brine densities sufficient to produce the required overbalance for well control, usually 200 psi ...
