European Journal of Organic Chemistry, EarlyView.Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

Energy-harvesting bio-electro-dehalogenation for sustainable wastewater treatment
, 2018 The concept of an “energy-harvesting bio-electro-dehalogenation” process is demonstrated, where exoelectrogenic bacteria in an anodic chamber of a microbial fuel cell (MFC) are used to capture and exploit the electrical energy stored in the biodegradable

Mechanisms of bacterially catalyzed reductive dehalogenation.
, 1992 Nine bacteria were tested for the ability to dehalogenate tetrachloromethane (CT), tetrachloroethene (PCE), and 1,1,1-trichloroethane (TCA) under anaerobic conditions. Three bacteria were able to reductively dehalogenate CT.

Heterogeneous Iodine Chemistry Impacts Reactive Halogen and Oxidant Abundances
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Tropospheric reactive halogens influence the oxidizing capacity of the atmosphere. Although previous studies have shown that iodine exerts the strongest impact on tropospheric ozone concentrations compared to chlorine and bromine, the impact of aerosol iodide recycling back to the gas phase on oxidants has not been estimated prior to this work.
