Adding to the Woes: Heterogeneous Effects of Air Pollution on Pandemic Patients.

While the direct health impacts of air pollution are widely discussed, its indirect effects, particularly during pandemics, are less explored. Utilizing detailed individual-level data from all designated hospitals in Wuhan during the initial COVID-19 outbreak, we examine the impact of air pollution exposure on treatment costs and health outcomes for COVID-19 patients. Our findings reveal that patients exposed more intensively to air pollution, identified by their residence in downwind areas of high-polluting enterprises, not only had worsened health outcomes but also consumed more medical resources.

A Novel Protein NLRP12-119aa that Prevents Rhabdovirus Replication by Disrupting the RNP Complex Formation.

The accurate assembly of the ribonucleoprotein (RNP) complex is fundamental for the replication and transcription of rhabdoviruses, which are known for their broad pathogenic impact. A novel 119-amino-acid protein, NLRP12-119aa is identified, encoded by the circular RNA circNLRP12, that effectively disrupts the formation of rhabdovirus RNP complexes through two distinct mechanisms and significantly reduces their replication. NLRP12-119aa exhibits a strong affinity for the conserved 18-nucleotide sequence at the start of the leader RNA of rhabdoviruses VSV, SCRV, and RABV, outcompeting their native N protein interactions, thereby disrupting the assembly of RNP complexes and inhibiting viral replication.

3D Printing Organogels with Bioderived Cyrene for High-Resolution Customized Hydrogel Structures.

3D printing techniques are increasingly being explored to produce hydrogels, versatile materials with a wide range of applications. While photopolymerization-based 3D printing can produce customized hydrogel shapes and intricate structures, its reliance on rigid printing conditions limits material properties compared to those of extrusion printing. To address this limitation, this study employed an alternative approach by printing an organogel precursor using vat polymerization with organic solvents instead of water, followed by solvent exchange after printing to create the final hydrogel material.

A Zero-gap Electrolyzer Enables Supporting Electrolyte-free Seawater Splitting for Energy-saving Hydrogen Production.

Membrane-assisted direct seawater splitting (DSS) technologies are actively studied as a promising route to produce green hydrogen (H2), whereas the indispensable use of supporting electrolytes that help to extract water and provide electrochemically-accelerated reaction media results in a severe energy penalty, consuming up to 12.5% of energy input when using a typical KOH electrolyte. We bypass this issue by designing a zero-gap electrolyzer configuration based on the integration of cation exchange membrane and bipolar membrane assemblies, which protects stable DSS operation against the precipitates and corrosion in the absence of additional supporting electrolytes.

However, the highly conserved binding pockets of CDKs complicate selective targeting.

Evolution of Two-Dimensional Perovskite Films Under Atmospheric Exposure and Its Impact on Photovoltaic Performance.

Two-dimensional (2D) Ruddlesden-Popper perovskites (RPPs) have garnered significant attention due to their enhanced stability compared with their three-dimensional counterparts.

Electrolyte Decoupling Strategy for Metal Oxide-Based Zinc-ion Batteries Free of Crosstalk Effect.

The crosstalk of transition metal ions between the metal oxide cathode and Zn anode restricts the practical applications of aqueous zinc-ion batteries (ZIBs). Herein, we propose a decoupled electrolyte (DCE) consisting of a nonaqueous-phase (N-phase) anolyte and an aqueous-phase (A-phase) catholyte to prevent the crosstalk of Mn2+, thus extending the lifespan of MnO2-based ZIBs. Experimental measurements and theoretical modelling verify that trimethyl phosphate (TMP) not only synergistically works with NH4Cl in the N-phase anolyte to enable fast Zn2+ conduction while block Mn2+ diffusion toward anode, but also modifies the Zn2+ solvation structure to suppress the dendrite formation and corrosion on Zn anode.
