Organic-inorganic hybrid Sn(IV)-based metal halides have received wide attention due to their excellent structural stability. However, realizing red-emitting Sn(IV)-based metal halides with high stability and efficient photoluminescence (PL) efficiency remains challenging. Here, a stable organic-inorganic Sn(IV)-based metal halide (CHON)SnCl with a zero-dimensional (0D) structure has been obtained, which, however, displays poor PL properties due to the inert expression of Sn-4d electrons and the intrinsic indirect band gap feature.

Exploring a zero-dimensional (0D) hybrid halide with a large Stokes shift and efficient broad-band emission is highly desirable due to its enormous potential for solid-state lighting (SSL) application. However, it is still challenging to develop a highly emissive 0D hybrid halide with low toxicity and remarkable stability. Herein, we developed a novel indium-based metal halide AInCl·4HO (A = doubly protonated 1,4-diaminobutane) whose inorganic octahedrons are completely isolated by the organic cations to form the 0D structure.

Developing an oral in situ-forming hydrogel that targets the inflamed intestine to suppress bleeding ulcers and alleviate intestinal inflammation is crucial for effectively treating ulcerative colitis (UC). Here, inspired by sandcastle worm adhesives, we proposed a water-immiscible coacervate (EMNs-gel) with a programmed coacervate-to-hydrogel transition at inflammatory sites composed of dopa-rich silk fibroin matrix containing embedded inflammation-responsive core-shell nanoparticles. Driven by intestinal peristalsis, the EMNs-gel can be actuated forward and immediately transform into a hydrogel once contacting with the inflamed intestine to yield strong tissue adhesion, resulting from matrix metalloproteinases (MMPs)-triggered release of Fe from embedded nanoparticles and rearrangement of polymer network of EMNs-gel on inflamed intestine surfaces.

It is of great significance to construct a Z-scheme heterojunction for improving solar light harvesting and achieving efficient separation of photogenerated carriers and then enhancement of the photocatalytic performance of semiconductor photocatalysts. Herein, the direct Z-scheme PI/AgWO heterojunction was designed and prepared according to the band edge potentials of the semiconductor. Due to the fact that the Z-scheme structure not only endowed the PI/AgWO composites with efficient separation of photogenerated electron-hole pairs but also reserved the redox ability of the valence band and conduction band of monophase catalysts, the 50% PI/AgWO heterojunction exhibited excellent photocatalytic activity, which were 2.

Article Synopsis
  • Previous studies on anterior circulation stroke indicate that endovascular treatment (EVT) may not benefit patients with poor collateral circulation, prompting a focus on basilar artery occlusion (BAO) in this study.
  • The BASILAR study analyzed 828 BAO patients, comparing outcomes between those receiving standard medical therapy (SMT) alone and those receiving SMT plus EVT based on their posterior circulation collateral score (PC-CS).
  • Results showed that good collateral circulation significantly improved the likelihood of favorable outcomes with EVT; patients with poor collaterals need early EVT within 6 hours, while those with moderate to good collaterals may have longer time windows for treatment.
