Clean up water blocking damage in coalbed methane reservoirs by microwave heating: laboratory studies
TL;DR: In this article, contact angle tests and permeability tests were performed to investigate the effects of microwave heating on water blocking damage in coalbed methane (CBM) reservoirs, and the results indicated that microwave heating can lead to hydrophobization of coal.

Reaction mechanisms involving peroxy radical in the low-temperature oxidation of coal
Zhilin Xi,BangXin Jin,Ze Shan +2 more
TL;DR: In this paper, the authors investigated the mechanisms whereby peroxy radicals participate in the low temperature oxidation of coal and proved the existence of active sites through charge distribution analysis, structural parameters, and frontier orbital analysis.
Journal ArticleDOI
Spectroscopic (FTIR, 1H NMR) and SEM investigation of physicochemical structure changes of coal subjected to microwave-assisted oxidant stimulation
TL;DR: In this article , the authors introduced the concept of using microwave-assisted oxidation for coalbed methane (CBM) reservoir, which can break the self-associating hydrogen bonds in carboxyl, alcohol, and phenol, converting them into ether groups.

Manganese Enzymes with Binuclear Active Sites
TL;DR: The purpose of this article is to summarize and illustrate the general principles of catalysis which distinguish binuclear metalloenzymes from monometallic centers and a summary of the major structurally characterized dimanganese enzymes is given.

Polyethylene glycol-superoxide dismutase, a conjugate in search of exploitation.
TL;DR: PEG-SOD has been shown to provide a greater resistance to oxidant stress, to improve endothelium relaxation and inhibit lipid oxidation and the effect of PEG conjugation was studied in vitro and in vivo models.

TL;DR: The new thermochemistry of HO2, together with other arguments given in the present work, suggests that the previous equilibrium constant for NO + HO2 --> OH - NO2 was underestimated by a factor of approximately 2, implicating that the OH + NO2 rate was overestimated by the same factor.
