Structure- and Morphology-Controlled Synthesis of Hexagonal Ni Zn P Nanocrystals and Their Composition-Dependent Electrocatalytic Activity for Hydrogen Evolution Reaction.

Nickel phosphides are an emerging class of earth-abundant catalysts for hydrogen generation through water electrolysis. However, the hydrogen evolution reaction (HER) activity of NiP is lower than that of benchmark Pt group catalysts. To address this limitation, an integrated theoretical and experimental study was performed to enhance the HER activity and stability of hexagonal NiP through doping with synergistic transition metals.

Legislative and regulatory barriers to pharmacies dispensing buprenorphine for OUD.

Introduction: Buprenorphine (BUP) is increasingly recognized and utilized as a valuable medication for the treatment of opioid use disorder. This article focuses on the problem of regulatory restrictions on access to buprenorphine products without naloxone (mono-product), involving patients in one geographic area, but which may represent a more general access problem in the United States.

Design: In response to an audit by the Tennessee Board of Pharmacy, a pharmacy in northeast Tennessee designed a questionnaire to survey patient motivation for traveling long distances to fill their prescriptions for BUP, rather than buprenorphine/naloxone (BNx, combo-product), and to document their satisfaction with treatment with the mono-product.

Desorption trends of small alcohols and the disruption of intermolecular interactions at defect sites on Au(111).

Gold-based catalysts have received tremendous attention as supports and nanoparticles for heterogeneous catalysis, in part due to the ability of nanoscale Au to catalyze reactions at low temperatures in oxidative environments. Surface defects are known active sites for low temperature Au chemistry, so a full understanding of the interplay between intermolecular interactions and surface morphology is essential to an advanced understanding of catalytic behavior and efficiency. In a systematic study to better understand the adsorption and intermolecular behavior of small alcohols (C-C) on Au(111) defect sites, coverage studies of methanol, ethanol, 1-propanol, 1-butanol, 2-butanol, and isobutanol have been conducted on Au(111) using ultrahigh vacuum temperature programmed desorption (UHV-TPD).
