Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...

SYSTEM DIVES WITH GAS MIXTURES BASED ON HELIUM
Annals: Series on engineering sciences (Academy of Romanian Scientists)Helium, being very inert from a biochemical point of view and having a density seven times lower than that of nitrogen, allows for superior performance by eliminating the effects of narcosis and breathing difficulties. By developing decompression tables

New opportunities for bioscaffold‐enabled spinal cord injury repair
BMEMat, EarlyView.Schematic illustration of bioscaffolds for spinal cord injury repair. We summarize the effects of bioscaffold properties on SCI repair, highlight different types of bioscaffolds, various fabrication strategies, and in vivo transformations for the clinical development of SCI‐repairing bioscaffolds.

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, EarlyView.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
