Sapphire Psyche

Sapphire Psyche is not a standardized term in biochemistry; it appears to combine sapphire, a crystalline form of aluminum oxide, with Psyche, a proper name used in astronomy and other fields. In biochemical research, sapphire may describe an inert, optically transparent substrate, whereas Psyche does not identify a recognized molecule, pathway, assay, or molecular mechanism. Consequently, the phrase alone cannot define a reproducible biochemical process, material, or application. Accurate interpretation requires additional context, such as a source, organism, compound name, instrument, or experimental method associated with the term.

High-pressure Sapphire Cell for Phase Equilibria Measurements of CO2/Organic/Water Systems

0 Views •

2014

The high pressure sapphire cell apparatus is a unique tool to study, without sampling, phase behavior under a wide range of pressures. Using a cathetometer, very precise volume measurements can be recorded to measure liquid expansion and phase composition. Thus, this synthetic method enables the study of (1) phase equilibria of multi-component mixtures and (2) the partition behavior of catalyst or model compounds as a function of pressure.

2017

We developed a novel technique in electron microscopy, "flash-and-freeze," that enables the visualization of membrane dynamics with ms temporal resolution. This technique combines the optogenetic stimulation of neurons with high-pressure freezing. Here, we demonstrate the procedures and describe the protocols in detail.
