Roll over transition metals-triarylamines are redox-catalysts, enabling olefin difunctionalization and C–H functionalization reactions by activating benzoyl peroxide.

background: symmetrical peripheral gangrene is usually associated with underlying medical problems and it is seldom seen in pregnancy. sepsis though common in a setting of delivery by unskilled midwife is rarely accompanied by symmetrical gangrene. case presentation: we report a case of symmetrical peripheral gangrene which occurred in the winter, triggered possibly by sepsis and a single dose ...

Background: Worldwide Intra-Uterine Growth Restriction carries out high rate of fetal and neonatal morbidity and mortality. Perinatal mortality rates are 4-8 times higher for growth-retarded infants. IUGR are subdivided into symmetrical and asymmetrical subtypes. Aim of Study: To focus on the actual incidence of each subtype of IUGR and disparities. Methods: Across-sectional descriptive study a...

The production of hydrogen through water splitting in a photoelectrochemical cell suffers from an overpotential that limits the efficiencies. In addition, hydrogen-peroxide formation is identified as a competing process affecting the oxidative stability of photoelectrodes. We impose spin-selectivity by coating the anode with chiral organic semiconductors from helically aggregated dyes as sensit...
