Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies () in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipa...

Influence of Extraction Conditions on Yield, PhysicochemicalCharacteristics, and Degree of Deacetylation of Chitosan Derived fromBlack Soldier Fly Cocoons

Abstract Black soldier fly (BSF) cocoons are a chitin-rich byproduct and a sustainable chitosan source. This study evaluated eight extraction protocols varying alkali type (sodium hydroxide (NaOH) or potassium hydroxide (KOH)), concentration, temperature, and duration, followed b...

Economic Incentives for Agrivoltaics Systems with Commodity Crops in the Midwestern United States

Abstract Declining costs of photovoltaic (PV) technology and rising market and policy incentives are leading to the growing deployment of PV on cropland in the US Midwest, leading to concerns about the displacement of food and feed crop production. Agrivoltaic (AV) technology ena...

Nickel(I) in an All-FerricNiFeS Cluster

Abstract Anaerobic carbon monoxide dehydrogenase (CODH) enzymes interconvert CO2 and CO under mild conditions and with near perfect selectivity. The CODH active site, termed the C-cluster, is a [NiFe3S4]-Feu cluster that can reside in several different oxidation states. Despite d...
