Dynamic Structure of Microbial Membrane under High Hydrostatic Pressure

Structure and stability of ZrSiO 4 under hydrostatic pressure

High hydrostatic pressure

The use of high pressure processing (HPP) in the food industry was developed as an alternative to common thermal processes, such as pasteurization and sterilization, to produce a microbiologically safe food while avoiding and reducing undesirable changes in sensory, physiochemical and nutritional properties of foods. The use of high pressure at high temperatures as a tool for sterilization (hig...

DYNAMIC SIMULATION OF A HIGH PRESSURE REGULATOR

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

Conformation of p-terphenyl under hydrostatic pressure.

The conformation of p-terphenyl (C18H14) and deuterated p-terphenyl (C18D14) has been investigated, using high-pressure infrared spectroscopy at liquid-helium temperatures. First-principles calculations, together with the experimental results, were performed to determine the structure of p-terphenyl in the twisted conformation. At low temperatures and pressures, p-terphenyl belongs to the C2 po...

Infrared spectroscopy of biphenyl under hydrostatic pressure

Changes in the conformations of conjugated molecules affect the optical and electronic properties significantly. Hydrostatic pressure has been used to probe the conformations of biphenyl (C12H10) and deuterated biphenyl (C12D10) at liquid-helium temperatures. Infrared ~IR! spectra of these materials have been taken up to a pressure of 2 GPa. A disappearance of certain IR absorption peaks has be...
