Spatiotemporally controlled drug release via a click-release system utilizing mono-alkyl-hydroxylamine and cyclooctyne chemistry [PDF]

Nature Communications
The advancement of bioorthogonal bond-breaking chemistry requires precise spatiotemporal control over chemical reactions. In this study, we introduce a click-release strategy based on the reaction between mono-alkyl-hydroxylamine and cyclooctyne (COT ...

Nitrous Oxide from Abiotic Processes of Hydroxylamine and Nitrite in Estuarine and Coastal Ecosystems: A Review

Journal of Marine Science and Engineering, 2022
Abiotic processes of nitrogen (N) are suggested to contribute to nitrous oxide (N2O) production; however, the important role of these processes in N2O emissions is invariably ignored.

Hydroxylamine enhanced activation of peroxymonosulfate by Fe(III)/Cu(II) bimetallic for high-efficiency degradation of AO7

Water Science and Technology, 2022
In this study, a new type of iron/copper bimetallic combined with hydroxylamine (HA) activated peroxymonosulfate (PMS) was constructed to treat organic pollutants. Selecting the azo dye acid orange 7 (AO7) as the representative of organic pollutants, the

Efficient transformation of hydroxylamine from wastewater after supplementation with sodium carbonate or calcium bicarbonate

Ecotoxicology and Environmental Safety, 2023
Hydroxylamine is a highly reactive inorganic nitrogen compound that not only has a toxic effect on microorganisms, but also makes wastewater treatment more difficult, which in turn damages the environment and even endangers human health.
