Thioborates are of interest as nonlinear optical materials, birefringent materials, and solid-state electrolytes. Under the dilemma that all known thioborate-thiosilates are disordered structures with co-occupied atomic sites, the first structurally ordered thioborate-thiosilicate, BaLa(SiS)(BS), has been successfully obtained by adjusting the cationic size. It features a novel 3D tunnel network assembled by La-B-S chains and La-Si-S bilayers. In addition, BaLa(SiS)(BS) exhibits good chemical and thermal stability (up to 880 °C), wide light transmission range (0.4-11 μm), wide band gap (3.25 eV), moderate birefringence (0.076 @ 546 nm), and high laser-induced damage threshold (6 × AgGaS). Theoretical calculations showed that the [BS] functional group is the main contributor to birefringence. This work enriches the structure types of thioborate-thiosilicate and expands insights into mixed anionic thioborates.

Acute abdomen can represent a serious clinical condition with a variety of different and potentially life-threatening underlying causes. Rapid identification of the underlying etiology through a structured approach and the prompt initiation of adequate diagnostic and treatment measures is highly relevant in order to reduce the patient's mortality risk. This article provides an overview of important differential diagnoses of an acute abdomen and describes recommended diagnostic and therapeutic measures that are relevant in acute and emergency clinical care.

Abnormal expression of HLA class Ib, MICA and MICB molecules is associated with the evolution of pathological conditions and clinical settings. Here, we use RNA-sequencing data from two publicly-available projects, from different human organs and tissues and at single-cell level, to present their transcriptional expression throughout the human body, in comparison to that of HLA class Ia, HLA class II, their costimulatory molecules, and the main HLA transcription factors. Our analyses for 21 target genes reveal that median gene expression differs by orders of magnitude and that the classical/non-classical HLA distinction is not absolute for overall expression.

Defects significantly influence charge transport in CHNHPbI (MAPbI) perovskite solar cells, particularly at interfaces. Using quantum dynamics simulation, we reveal a distinct interstitial iodine (I) defect behavior at different positions in the TiO/MAPbI system. In the perovskite bulk-like region, I exhibits high mobility and dissociates detrimental iodine trimers, facilitating small-to-large polaron transition and promoting shallow trap formation.

Isovalent anion substitution has been shown to have a tremendous effect on the transport properties in lithium halide solid ionic conductors. Although sodium-ion solid state batteries based on chloride ionic conductors have recently gathered significant attention, investigations of anion substitution in sodium containing chlorides remain scarce. Here, we investigate the role of Br isoelectronic anion substitution in a perovskite-related compound with nominal composition of NaTaCl.

Sarcosine (Sar), a critical potential biomarker for prostate cancer (PCa), is primarily detected via enzyme cascade reactions involving sarcosine oxidase (SOx) and peroxidase. Nevertheless, the intermediate product hydrogen peroxide (HO) tends to diffuse to the bulk solution phase without entering subsequent reaction, leading to suboptimal detection sensitivity and compromised analytical performance. To tackle this challenge, a multilayered sandwich nanozyme cascade sensor (designated as Cu-MOF/Rf@BDC) is proposed through a confinement-mediated HO enrichment strategy.
