Non-Steady State Validation of Kinetic Models for Ethylene Epoxidation over Silver Catalysts [PDF]
Kinetic modelling has been key to developing a mechanistic understanding of the epoxidation of ethylene to ethylene oxide over silver catalysts. However, models of varying active site and mechanistic complexity have all been able to recreate steady state

Uptake, metabolism, and bioremediation of neonicotinoid insecticides in soil–plant systems: A review
New Plant Protection, EarlyView.This review summarizes the uptake and metabolic transformation of neonicotinoid insecticides in plants, showing that some metabolites exhibit higher toxicity. We also critically assess promising bioremediation strategies using microbes and plant–microbe interactions to reduce residue contamination.

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane
Journal of Polymer Science, EarlyView.Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Selective aerobic radical epoxidation of alfa-olefins catalyzed by N-hydroxyphthalimide
, 2008 The combination of N-hydroxyphthalimide (NHPI) and peracids is employed for the free-radical epoxidation of alkenes with high yields. A quite different selectivity is obtained from that of the well-known epoxidation by peracids, which is attributed to a ...
