Thermal Hydroquinone Oxidation on Co/N-doped Carbon Proceeds by a Band-Mediated Electrochemical Mechanism.

Molecular metal complexes catalyze aerobic oxidation reactions via redox cycling at the metal center to effect sequential activation of O and the substrate. Metal surfaces can catalyze the same transformations by coupling independent half-reactions for oxygen reduction and substrate oxidation mediated via the exchange of band-electrons. Metal- and nitrogen-doped carbons (MNCs) are promising catalysts for aerobic oxidation that consist of molecule-like active sites embedded in conductive carbon hosts.

Redox-Induced Structural Reorganization Dictates Kinetics of Cobalt(III) Hydride Formation via Proton-Coupled Electron Transfer.

Two-electron, one-proton reactions of a family of [CoCp(dxpe)(NCCH)] complexes (Cp = cyclopentadienyl, dxpe = 1,2-bis(di(aryl/alkyl)phosphino)ethane) form the corresponding hydride species [HCoCp(dxpe)] (dxpe = dppe (1,2-bis(diphenylphosphino)ethane), depe (1,2-bis(diethylphosphino)ethane), and dcpe (1,2-bis(dicyclohexylphosphino)ethane)) through a stepwise proton-coupled electron transfer process. For three [CoCp(dxpe)(NCCH)] complexes, peak shift analysis was employed to quantify apparent proton transfer rate constants from cyclic voltammograms recorded with acids ranging 22 p units. The apparent proton transfer rate constants correlate with the strength of the proton source for weak acids, but these apparent proton transfer rate constants curiously plateau () as the reaction becomes increasingly exergonic.

"When Her Visa Expired, the Family Refused to Renew It," Intersections of Human Trafficking and Domestic Violence: Qualitative Document Analysis of Case Examples from a Major Midwest City.

This study aimed to further understand typologies of trafficking that occur in the home, by an individual's intimate partner (IP) or family members and this overlap with extant knowledge on perpetrator manipulation via the Power and Control Wheel. Inductive and deductive techniques were used to analyze secondary data from a federally funded anti-trafficking program in a Midwest metropolitan area recorded between 2008 and 2017. Cases were included if there was indication of sex or labor exploitation initiated by an IP, family member, or other in the domestic setting via elements of abuse; 59 cases of 213 met this criteria.
