Enhanced Biocatalysis in Nanofluidic Membrane Reactors With Goldilocks Nanopores for Enzymes

Small, EarlyView.
We show that enzyme confinement within the three‐dimensionally interconnected nanochannels of a polyurea molecular network membrane, featuring pore‐size tunability to match the enzyme size, enables a highly active nanofluidic reactor platform. Stable continuous‐flow operation for >200 h and a 30 000‐fold increase in specific space‐time yield over ...

Étude de réactions d'estérification et de transestérification de fibres, fils et tissus de coton à l'aide de réactifs gras, en vue de leur conférer un caractère hydrophobe [PDF]

, 2000
Le coton est la fibre textile végétale la plus utilisée mais elle est souvent remplacée par des fibres synthétiques pour des utilisations extérieures du fait de son caractère hydrophile.

Biodiesel Production from Hevea brasiliensis Seeds: A Systematic Review

Vietnam Journal of Chemistry, EarlyView.
ABSTRACT The Hevea brasiliensis (HB) species, also called the rubber tree, is currently cultivated worldwide for the extraction of latex, an input for rubber production. In addition, its seeds currently have few productive applications, despite their high oil content.

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Catalytic behavior of Carica papaya latex in transesterification reactions [PDF]

, 1997
La réaction de transestérification biocatalysée par le latex de Carica papaya est étudiée entre la tricapryline et différents donneurs d'acyles. Avec le latex brut, les triacylglycérols transestérifiés sont obtenus avec de bons rendements avec le laurate

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐
