Novel Non‐Cytotoxic Acylphosphinates and Acylphosphine Oxides Photoinitiators

Angewandte Chemie, EarlyView.
Novel acylphosphine oxide (APO) and acylphosphinate photoinitiators based on DPO and DOPO were designed to investigate structure–property relationships including photochemical performance, polymerization efficiency and cytotoxicity. While DPO derivatives showed excellent reactivity, DOPO‐based systems also displayed good efficiency and significantly ...

Clouds, photolysis and regional tropospheric ozone budgets. [PDF]

, 2009
We use a three-dimensional chemical transport model to examine the shortwave radiative effects of clouds on the tropospheric ozone budget. In addition to looking at changes in global concentrations as previous studies have done, we examine changes in ...

Hydrogen (H2) Recovery From Hydrogen Sulfide (H2S): Current Technologies, Challenges, and Future Outlook

Advanced Science, EarlyView.
ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

Light‐Activated Isolation of High‐Quality Mitochondria for Therapeutic Transplantation

Angewandte Chemie, EarlyView.
The Light‐Activated Mitochondrial Isolation (LAMI) platform enables the selective and non‐destructive isolation of high‐purity, metabolically active mitochondria. By integrating modular, ligand‐programmable magnetic probes with photo‐cleavable release, LAMI overcomes long‐standing limitations of conventional isolation methods and provides a robust ...

Reaction of superoxide radicals with glycosaminoglycan chloramides: a kinetic study.

, 2013
Hypochlorous acid and its acid-base counterpart, hypochlorite ions, produced under inflammatory conditions, may produce chloramides of glycosaminoglycans, perhaps through the binding of myeloperoxidase directly to the glycosaminoglycans.
