Selective Electrocatalytic Water Oxidation to Produce HO Using a C,N Codoped TiO Electrode in an Acidic Electrolyte.

Production of hydrogen peroxide (HO) via in situ electrochemical water oxidation possesses great potential applications in the energy and environment fields. In this work, for the first time, we reported a C,N codoped TiO electrode for selective electrocatalytic water oxidation to produce HO in an acidic electrolyte. An electrochemical anodic oxidation method combined with postcalcination in the presence of urea was applied to fabricate such a C,N codoped TiO electrode, which was evidenced by detail structural characterizations.

[Role of acute alcohol poisoning and craniocerebral trauma in the mechanism of death caused by subarachnoid hemorrhage].

Objective: To investigate the relation between the expression of tPA, MMP-2, MMP-9 and AEG-1 in the human brain tissue and the ethanol concentration under the acute alcohol poison, and to analyze the role of alcohol and trauma in the mechanism of death of subarachnoid hemorrhage.

Methods: Fifteen real cases were collected in this study. The brain tissues were researched by histological examination and the concentration of ethanol in heart blood were detected.
