Effects of nanoselenium on the performance, blood indices, and milk metabolites of dairy cows during the peak lactation period.

To compare the impact of nanoselenium and sodium selenite on the performance, blood indices, and milk metabolites of dairy cows during the peak lactation period, two groups of dairy cows under the same conditions were selected as the control group (CON group) and treatment group (NSe group) for a 38-day (10 days for adaptation and 28 days for sampling) experiment.

Molecular recognition between volatile molecules and odorant binding proteins 7 by homology modeling, molecular docking and molecular dynamics simulation.

Background: Odorant-binding proteins (OBPs) in insects are key to detection and recognition of external chemical signals associated with survival. OBP7 in Spodoptera frugiperda's larval stage (SfruOBP7) may search for host plants by sensing plant volatiles, which are important sources of pest attractants and repellents. However, the atomic-level basis of binding modes remains elusive.

Study on the efficiency and recyclability of Fenton-MnFeO for the degumming of hemp fibers.

Traditional alkali degumming (TAL) has been widely used for hemp degumming; however, the produced degumming waste liquid pollutes the environment. For this phenomenon, an improved Fenton oxidation degumming process was developed in this study, that is, MnFeO (Fenton-MnFeO) was added to the Fenton system. The purpose was to reduce the reaction time and the addition of chemical reagents, and reuse the added MnFeO.

Synergistic defect and doping engineering building strong bonded S-scheme heterojunction for photocatalysis.

Photocatalytic degradation of pollutants is considered a promising approach for wastewater treatment, but is hampered by low efficiency and limited understanding of degradation pathways. A novel oxygen-doped porous g-CN/oxygen vacancies-rich BiOCl (OCN/OVBOC) heterostructure was prepared for photocatalytic degradation of bisphenol A (BPA). The synergistic defect and doping engineering favor the formation of strong bonded interface for S-scheme mechanism.
