High-Pressure Structures

High-pressure structural foam products have generally been found to require little or no postfinishing. Although high-pressure foam products may exhibit visual splay, their surface smoothness is maintained and no sanding or filling is required.

High-pressure structures are capable of withstanding pressures of more than 1.5 psig (0.1 bar gauge). The vent design is based on the definition of a deflagration index for gases or dusts ...

What are the specific characteristics of the high-pressure structure studies of organic conductors Compared to simple minerals, the pressure range is lower, but molecular materials are more sensitive to nonhydrostatic stress, diffract an order of magnitude less, the cell dimensions are larger, and thus more reflections must be collected. In practice, three types of pressure vessels are often used in the diffraction experiments.

In this review, we first briefly summarize pressure effects in molecular biology and applications in biotechnology. We then discuss some experimental techniques and finally we discuss in more detail results of studies on the high pressure structure and phase behavior of biomolecular systems, such as nucleic acids, lyotropic lipid mesophases, model biomembrane systems and proteins.
