Biomimetic [MFeS] Cubanes (M = V/Mo) as Catalysts for a Fischer-Tropsch-like Hydrocarbon Synthesis─A Computational Study.

Nitrogenase is the enzyme primarily responsible for reducing atmospheric nitrogen to ammonia. There are three general forms of nitrogenase based on the metal ion present in the cofactor binding site, namely, molybdenum-dependent nitrogenases with the iron-molybdenum cofactor (FeMoco), the vanadium-dependent nitrogenases with FeVco, and the iron-only nitrogenases. It has been shown that the vanadium-dependent nitrogenases tend to have a lesser efficacy in reducing dinitrogen but a higher efficacy in binding and reducing carbon monoxide.

Older Adults' Use of Cannabis and Attitudes Around Disclosing Medical Cannabis Use to Their Healthcare Providers in California: A Mixed Methods Study.

Background: The rapidly changing policy climate related to cannabis legalization has led to drastic changes in cannabis use in the United States (US). Medical cannabis use is increasing overall, but at a faster rate among older adults compared to other age groups.

Objective: The aim was to investigate older adults' cannabis use behaviors and attitudes around disclosing medical cannabis use to their primary healthcare providers (HCPs).
