Cold atmospheric plasma can effectively disinfect SARS-CoV-2 in the wastewater

Cold atmospheric plasma can produce peroxynitrite (ONOO−), ozone (O3), superoxide anion radicals (O2−), and hydrogen peroxide (H2O2) as the major reactive species to inactivate coronaviruses by disrupting the viral Spike protein and genomic RNA, thus hindering viral entry and replication. This study highlights the potential of cold atmospheric plasma as a promising approach to combat …

Cerebrospinal fluid efflux through dynamic paracellular pores on venules as a missing piece of the brain drainage system

A novel drainage pathway through which cerebrospinal fluid (CSF)/interstitial fluid (ISF) molecules enter the bloodstream directly via dynamically assembled trumpet-shaped pores on the walls of brain venules was discovered. An updated model for glymphatic clearance of brain metabolites and potential roles in the Alzheimer disease and some neurological disorders are discussed. Abstract: The glymphatic system …

The dissolution, reassembly and further clearance of amyloid-β fibrils by tailor-designed dissociable nanosystem for Alzheimer’s disease therapy

A tailor-designed dissociable nanosystem can decompose into small nanostructures in brain microenvironment of Alzheimer’s disease, and then recognize and bind amyloid-β for the dissolution, reassembly and further clearance of amyloid-β fibrils. This nanosystem rescues cognitive and memory impairments in mice for Alzheimer’s disease therapy. Abstract: The fibrillation of amyloid-β (Aβ) is the critical causal factor …

Ion cocktail therapy for myocardial infarction by synergistic regulation of both structural and electrical remodeling

The ion cocktail, consisting of silicate, strontium and copper could attenuate both electrical and structural remodeling after myocardial infarction in rat and Bama minipigs. The therapeutic effect of ion cocktail on myocardial infarction may account for that different ions in the cocktail have different functions to regulate cellular behaviors. Abstract: Myocardial infarction (MI) is a …

Tumour-microenvironment-responsive Na2S2O8 nanocrystals encapsulated in hollow organosilica–metal–phenolic networks for cycling persistent tumour-dynamic therapy

Traditional tumour-dynamic therapy still inevitably faces the critical challenge of limited reative oxygen species (ROS)-generating efficiency due to tumour hypoxia, strict Fenton reaction conditions, and un-sustainable mono-catalytic reaction. To fight against these issues, a tumour–microenvironment-responsive yolk–shell nanoreactor is developed to realize the high-efficiency, selective, and sustainable dynamic therapy via cascade-responsive dual cycling amplification of •SO4−/•OH …

Unveiling of a puzzling dual ionic migration in lead- and iodide-deficient halide perovskites (d-HPs) and its impact on solar cell J–V curve hysteresis

In the present paper, a phenomenon of ionic migration of large organic cations in the lead- and iodide-deficient perovskite films is unveiled. This phenomenon is intrinsic to the structure and at the origin of a large hysteresis in the measured J–V curves. Contrary to iodide, it cannot be fully blocked through defect passivation by potassium …

Dichroic switching of core–shell plasmonic nanoparticles on reflective surfaces

Spray coating of the obtained core/shell nanostructures (a metal core and a dielectric shell) on reflective substrates produces dichroic films that can display colour switching at different viewing angles. The unique dichroic effect and high-contrast colour-switching are achieved by leveraging the resonant scattering and absorption of light by plasmonic nanostructures and the specular reflection of …
