Advanced Science, EarlyView.Tools for controlled selenol delivery are crucial for exploring Se‐related biology and medicine, but compound platforms for triggerable release of CH3SeH remain lacking. Herein, we report the first general triggered platform (TD‐MSe) for efficient cyclization release of CH3SeH in live cells.

Biological Monitoring for Isocyanates [PDF]
The Annals of Occupational Hygiene, 2007 Isocyanates are reactive chemicals and thousands of workers may be exposed to them during their manufacture and use in a wide range of products. They are classed as sensitizers and are a major cause of occupational asthma in the UK. Workplace exposure limits are low and control of exposure often depends on personal respiratory protection.

Critical reviews in environmental science and technology, 2019 Commercially available polyurethanes are synthesized by the polyaddition of diisocyanates with polyols and low molecular weight chain extenders. A new approach to polyurethanes synthesis is realized via non-isocyanate routes.

Water-based Non-Isocyanate Polyurethanes-Polyureas (NIPUUs)
, 2020 Non-isocyanate polyurethane-ureas (NIPUUs) are a greener alternative to the traditional isocyanate-based polyurethane-ureas. These materials are synthesized by transurethanization and aminolysis of cyclic carbonate, commonly performed in solvents and in ...

Advanced Science, EarlyView.A bio‑based thermoresponsive controlled‑release fertilizer (TRBF) is fabricated by introducing F127 into a castor‑oil‑derived polyurethane coating. Distinct from conventional bio‑based coated fertilizer (BCF), TRBF achieves temperature‑regulated nitrogen release via F127 reversible phase transition, suppressing nutrient leakage at low temperature and ...

Polymers, 2020 Crude jatropha oil (JO) was modified to form jatropha oil-based polyol (JOL) via two steps in a chemical reaction known as epoxidation and hydroxylation. JOL was then reacted with isocyanates to produce JO-based polyurethane resin.
