Study on the Movement and Deposition of Particles in Supercritical Water Natural Circulation Based on Grey Correlation Theory

open access: yesEnergies, 2019
The movement and deposition of particles that occur during their natural circulation in supercritical water exercise an important impact on the safe and stable operation of a supercritical water reactor (SCWR). When supercritical water flows in pipelines,

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Numerical simulation of supercritical-fluid flows over arbitrary geometry

open access: yesJournal of Fluid Science and Technology, 2014
In this study, numerical simulations of supercritical-water flows over an arbitrary geometry are presented. In the present method, the supercritical-fluids simulator (SFS) developed by the authors is coupled with the building-cube method (BCM).

Development of a prototype experiment for treating CELSS and PCELSS wastes to produce nutrients for plant growth [PDF]

open access: yes
Future long term spaceflights require extensive recycling of wastes to minimize the need for resupplying the vessel. The recycling occurs in a fully or partially closed environment life support system (CELSS or PCELSS). The National Aeronautics and Space

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.
