This excellent performance is believed to be the result of the exotic pine-needle-like nanocluster structure with effective accessibility of dense catalytically active sites, as well as the high specific surface area and the promotion of reversible chemisorption for oxygen species due to the linkers interacting with Co ions. Further SEM, TEM, and XPS analyses of the catalyst after OER stability tests reveal that the formation of Co3O4 on the surface and unconsolidated architecture withinthe electrode materials are responsible for the high catalytic activity. This work extends the applications of MOFs in the field of electrocatalysis.Chemically exfoliated MoS2 (ce-MoS2) nanosheets have been widely used in biomedical and environmental fields. Some in vitro studies demonstrated that ce-MoS2 might induce toxicity. However, the understanding of the mechanism of potential toxicity is lacking. In this study, we found that ce-MoS2 could directly induce breakage of double-stranded DNA with or without an external energy input, making it different from other two-dimensional nanomaterials. In a dark environment, the DNA cleavage exhibited a pH-dependent trend due to reactive oxygen species generation under different pH values. Under photoirradiation, DNA cleavage could be enhanced. This study provides insights into the potential environmental risk and toxicity of ce-MoS2 in the aquatic environment.The progressive accumulation of amyloid-beta (Aβ) in specific areas of the brain is a common prelude to late-onset of Alzheimer's disease (AD). Although activation of liver X receptors (LXR) with agonists decreases Aβ levels and ameliorates contextual memory deficit, concomitant hypercholesterolemia/hypertriglyceridemia limits their clinical application. DMHCA (N,N-dimethyl-3β-hydroxycholenamide) is an LXR partial agonist that, despite inducing the expression of apolipoprotein E (main responsible of Aβ drainage from the brain) w
