Method for growth of crystals by pressure reduction of supercritical or subcritical solution [PDF]

open access: yes, 1985
Crystals of high morphological quality are grown by dissolution of a substance to be grown into the crystal in a suitable solvent under high pressure, and by subsequent slow, time-controlled reduction of the pressure of the resulting solution. During the

Studies on the use of supercritical ammonia for ceramic nitride synthesis and fabrication [PDF]

open access: yes
The extractability of ammonia halides (including ammonium thiocyanate) formed as byproducts from the synthesis of Si(NH)2 via ammonolysis of the corresponding silicon tetrahalides using supercritical NH3 as the extraction medium was investigated.

Research on the Characteristics and Mechanisms of Supercritical CO2 Displacement of Shale Oil Under Nanoscale Confinement

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Shale reservoirs, characterized by compact pores, poor physical properties, and high organic matter content, exhibit significant differences in microscopic flow behavior compared to conventional oil reservoirs. These distinctions complicate the accurate assessment of shale oil reserves and the selection of optimal exploration and development ...

A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

open access: yesFood Frontiers, EarlyView.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...
