Insight into copper coordination in O reduction by water-soluble cytochrome oxidase models.

Iron-copper complexes have been extensively studied in the search for efficient cytochrome oxidase models. Whereas most dinuclear materials usually focus on fine-tuning the coordination of heme-Fe, this work shows that the coordination of copper in cytochrome oxidase models should be carefully taken into consideration. A β-cyclodextrin dimer was built around a bipyridine linker and combined with Fe-tetraphenylsulfonatoporphyrinate (FeTPPS) to generate a self-assembled hydrosoluble cytochrome oxidase model.

Atomically Dispersed Ni-N-C Catalysts for Electrochemical CO Reduction.

The atomic dispersion of nickel in Ni-N-C catalysts is key for the selective generation of carbon monoxide through the electrochemical carbon dioxide reduction reaction (CORR). Herein, the study reports a highly selective, atomically dispersed Ni-N-C catalyst with reduced Ni loading compared to previous reports. Extensive materials characterization fails to detect Ni crystalline phases, reveals the highest concentration of atomically dispersed Ni metal, and confirms the presence of the proposed Ni-N active site at this reduced loading.

Lifetime risk and projected burden of dementia.

Understanding the lifetime risk of dementia can inform public health planning and improve patient engagement in prevention. Using data from a community-based, prospective cohort study (n = 15,043; 26.9% Black race, 55.

Evaluation of a Program Designed to Support Implementation of Prescribing Medication for Treatment of Opioid Use Disorder in Primary Care Practices.

Purpose: Offering medication for opioid use disorder (MOUD) in primary care can increase access to effective opioid use disorder treatment and help address the US opioid crisis. We describe a primary care office-based opioid treatment program and addiction consultation service model designed to support small, rural clinics to increase their capacity for MOUD.

Methods: This is an evaluation of an intervention to increase clinic capacity to offer MOUD.
