Estimation of 1 km Dawn-Dusk All-Sky Land Surface Temperature Using a Random Forest-Based Reanalysis and Thermal Infrared Remote Sensing Data Merging (RFRTM) Method.

All-sky 1 km land surface temperature (LST) data are urgently needed. Two widely applied approaches to derive such LST data are merging thermal infrared remote sensing (TIR)-passive microwave remote sensing (PMW) observations and merging TIR reanalysis data. However, as only the Moderate Resolution Imaging Spectroradiometer (MODIS) is adopted as the TIR source for merging, current 1 km all-sky LST products are limited to the MODIS observation time.

Application of therapeutical nanoparticles with neutrophil membrane camouflaging for inflammatory plaques targeting against atherosclerosis.

Atherosclerosis is the leading cause of cardiovascular disease and myocardial infarction. Precise and effective plaque targeting is a major objective for therapeutic outcomes throughout various stages of atherosclerosis. Inspired by the natural recruitment of neutrophils in atherosclerotic plaques, we fabricated a simvastatin (ST)-loaded and neutrophil membrane-cloaked nanoplatform (NNP) for enhancing localized payload delivery and atherosclerosis management.

Insight into Robust Anion Coordination Behavior of Organic Cathode with Dual Elongated π-Conjugated Motifs.

Organic electrode materials offer multi-electron reactivity, flexible structures, and redox reversibility, but encounter poor conductivity and durability in electrolytes. To overcome above barriers, we propose a dual elongation strategy of π-conjugated motifs with active sites, involving the extended carbazole and electropolymerized polymer, which enhances electronic conductivity by the electronic delocalization of electron-withdrawing conjugated groups, boosts theoretical capacity by increasing redox-active site density, and endows robust electrochemical stability attributed to the nanonetwork feature of polymer structures. As a proof-of-concept, 5,11-dihydridoindolo[3,2-b]carbazole (DHIC) is selected as the model cathode material for a dual-ion battery, with elongated carbazole groups functioning both as redox-active centers and polymerization anchors.

An injectable carboxymethyl chitosan-based hydrogel with controlled release of BMP-2 for efficient treatment of bone defects.

Although biological scaffolds containing bone morphogenetic protein-2 (BMP-2) have been widely used for osteogenic therapy, achieving stable and controlled release of BMP-2 remains a challenge. Herein, a novel BMP-2 sustained-release system composed of carboxymethyl chitosan (CMCS)/polyethylene glycol (PEG)/heparin sulfate (HS) (CMCS/PEG/HS) was constructed with a Schiff base reaction, yielding an injectable hydrogel for the release of BMP-2 in a controlled manner. For the CMCS/PEG/HS/BMP-2 hydrogel, the HS component had a negatively charged structure, which can bind to positively charged growth factors and prevent early hydrolytic metabolism of growth factors, thus achieving sustainable release of BMP-2.

Variant-Localized High-Concentration Electrolyte without Phase Separation for Low-Temperature Batteries.

Dual-ion batteries (DIBs) present great application potential in low-temperature energy storage scenarios due to their unique dual-ion working mechanism. However, at low temperatures, the insufficient electrochemical oxidation stability of electrolytes and depressed interfacial compatibility impair the DIB performance. Here, we design a variant-localized high-concentration solvation structure for universal low-temperature electrolytes (ν-LHCE) without the phase separation via introducing an extremely weak-solvating solvent with low energy levels.

A Freestanding, Dissolution- and Diffusion-Limiting, Flexible Sulfur Electrode Enables High Specific Capacity at High Mass Loading.

The acquisition of stable and high-areal-capacity S cathodes over 10 mA h cm is a critical and indispensable step to realize the high energy density configuration. However, increasing the areal capacity of S cathodes often deteriorates the specific capacity and stability due to the aggravated dissolution of S and diffusion of solvable polysulfides in the thick electrode. Herein, the design of a freestanding composite cathode that leverages 3D covalent binding sites and chemical adsorption environment to offer dissolution-limiting and diffusion-blocking functions of S species is reported.

SARS-CoV-2 spike protein plays a key role in mediating viral entry and inducing host immune responses. It can adopt either an open or closed conformation based on the position of its receptor-binding domain (RBD). It is yet unclear what causes these conformational changes or how they influence the spike's functions.

Nonreducing Ambient Atmosphere: Pulsed Electric Current Treatment of Co/Ni Doped Perovskite Oxides to Achieve Exsolution Enhanced Electrochemical Performance.

Exsolution of metal nanoparticles (NPs) on the surface of perovskite oxides is a promising approach for developing advanced catalytic materials through a "bottom-up" design strategy. Under a nonreducing ambient atmosphere utilizing pulsed electric current (PEC) treatment to promote the exsolution of perovskite oxides effectively overcomes the limitations inherent in conventional high-temperature vapor phase reduction (HTVPR) exsolution methods.

Current collectors are indispensable parts that provide electron transport and mechanical support of electrode materials in a battery. Nowadays, thin metal foils made of Cu and Al are used as current collectors of lithium batteries, but they do not contribute to the storage capacity. Therefore, decreasing the weight of current collectors can directly enhance the energy density of a battery.
