Fluorescence detection of hydroxyl radicals in water produced by atmospheric pulsed discharges [PDF]

open access: yes, 2015
It has been proven that hydroxyl (OH) radicals can be generated by streamer discharges across water surfaces under ambient atmospheric conditions. Hydroxyl radicals have the highest oxidation capability amongst all oxygen-based reactive species, thus OH ...

Aromatic Diester Anolytes for Nonaqueous Redox Flow Batteries

open access: yesBatteries &Supercaps, EarlyView.
Owing to their extended π‐conjugation 2,2′‐bipyridyl aromatic diesters are stable in singly‐ and doubly‐reduced states. In a redox flow battery a high battery voltage of 2.82 V can be realized and a capacity a capacity retention of 99.5% per cycle for 260 cycles.

Synthesis of terephthalic acid via Diels-Alder reactions with ethylene and oxidized variants of 5-hydroxymethylfurfural [PDF]

open access: yes, 2014
Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA.

Enhanced Electrooxidation of Glycerol to Lactate Over FeOx‐Modified Au Catalysts

open access: yesCarbon and Hydrogen, EarlyView.
A FeOₓ‐modified Au catalyst on nickel foam, fabricated via facile electrodeposition, achieves high‐current‐density (310 mA cm−2) and selective (78.1%) electrooxidation of glycerol to lactate at room temperature, offering a sustainable route for biodiesel by‐product valorization.
