The atmospheric methane trend is not fully understood. Here we investigate the role of the main sink, the main natural source, and anthropogenic emissions on the methane growth rate over the last three decades using numerical models and emission ...

Radical Chemistry in a Femtosecond Laser Plasma: Photochemical Reduction of Ag+ in Liquid Ammonia Solution [PDF]
Plasmas with dense concentrations of reactive species such as hydrated electrons and hydroxyl radicals are generated from focusing intense femtosecond laser pulses into aqueous media. These radical species can reduce metal ions such as Au3+ to form metal

Design of a two-dimensional interplanar heterojunction for catalytic cancer therapy
Chemodynamic therapy relies on Fenton or Fenton-like reactions to produce hydroxyl radical in the tumor region. Here the authors design a two-dimensional interplanar heterojunction with in situ hydroxyl radical generation under ultrasound irradiation ...

Study on Hydroxyl Radical Scavenging Ability of Fermented Kelp Waste
In order to develop a new pathway to scavenge hydroxyl radical and to utilize kelp waste, edible-medicinal fungi was fermented in medium mainly composed of kelp waste, and the products from fermentation were investigated with hydroxyl radical scavenging ...

Glutathione--hydroxyl radical interaction: a theoretical study on radical recognition process. [PDF]
Non-reactive, comparative (2 × 1.2 μs) molecular dynamics simulations were carried out to characterize the interactions between glutathione (GSH, host molecule) and hydroxyl radical (OH(•), guest molecule).

Atmospheric chemistry of gas-phase polycyclic aromatic hydrocarbons: formation of atmospheric mutagens. [PDF]
The atmospheric chemistry of the 2- to 4-ring polycyclic aromatic hydrocarbons (PAH), which exist mainly in the gas phase in the atmosphere, is discussed. The dominant loss process for the gas-phase PAH is by reaction with the hydroxyl radical, resulting

DNA binding hydroxyl radical probes [PDF]
The hydroxyl radical is the primary mediator of DNA damage by the indirect effect of ionizing radiation. It is a powerful oxidizing agent produced by the radiolysis of water and is responsible for a significant fraction of the DNA damage associated with ionizing radiation.

Antioxidant activity of mandarin (Citrus reticulata) peel [PDF]
Mandarin peel, a waste product coming from juice production, was extracted by conventional extraction with 70% acetone. Content of flavonoids in mandarin peel extract (MPE) was determined by HPLC. Hesperidin was the most dominant flavonoid.
