Article Synopsis
- Two different isomeric forms of indium bromide crystals, α and β, were created by altering cooling conditions during their synthesis.
- Structural differences reveal varied supramolecular interactions, supported by Hirshfeld surface analysis.
- The α form exhibits a significantly higher photoluminescence quantum yield due to its compact structure and effective electron transfer processes, offering insights for future design of luminescent indium-based materials.*
Recently zero-dimensional (0-D) inorganic-organic metal halides (IOMHs) have become a promising class of optoelectronic materials. Herein, we report a new photoluminescent (PL) 0-D antimony(III)-based IOMH single crystal, namely [HBPZ][SbCl]·HO (BPZ = benzylpiperazine). Photophysical characterizations indicate that [HBPZ][SbCl]·HO exhibits singlet/triplet dual-band emission.

- Zero-dimensional organic-inorganic metal halides (OIMHs), particularly hybrid antimony(III) bromides (HABs), have potential for high photoluminescence quantum yields (PLQYs), but current values are lower compared to their chloride counterparts.* -
- Researchers developed a method to enhance PLQYs by synthesizing two structurally similar HABs with different solvent molecules, resulting in notable differences in their emission properties and PLQYs, specifically a nearly twofold increase in PLQY for one compound.* -
- The improvement in PLQY is linked to structural changes influenced by hydrogen bonding between the inorganic components and solvent molecules, underscoring the importance of structural rigidity in optimizing the phot
Article Synopsis
- The study focuses on the importance of radiocesium remediation for ecological safety, human health, and sustainable nuclear energy development.
- Researchers have developed a robust material, KInSnS (InSnS-1), which effectively captures cesium (Cs) from strongly acidic solutions, overcoming challenges related to material stability and competition from protons.
- The material not only has a high capacity for Cs adsorption but also serves in ion exchange processes; its selective adsorption mechanisms have been analyzed using single-crystal structure techniques.
Background: Glucocorticoid-remediable aldosteronism (GRA) is a form of heritable hypertension caused by a chimeric fusion resulting from unequal crossing over between 11β-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2), which are two genes with similar sequences. Different crossover patterns of the CYP11B1 and CYP11B2 chimeric genes may be associated with a variety of clinical presentations. It is therefore necessary to develop an efficient approach for identifying the differences between the hybrid genes of a patient with GRA.

- The compound [Cmim][Mim][SbCl] features dual cations and is the first to demonstrate deep-red emission in zero-dimensional organic-inorganic hybrid materials.
- The emission is attributed to significant anion distortion caused by imbalanced supramolecular interactions.
- This results in a remarkably large Stokes shift of 335 nm and a full width at half maximum (FWHM) of 210 nm in the emission spectrum.
Article Synopsis
- Zero-dimensional metal halides, particularly [EtPPh][SbCl], are gaining interest for their ability to switch luminescence, making them useful for sensors and anticounterfeiting.
- Research showed that only solvent molecules with a volume less than 22.3 Å can interact with [EtPPh][SbCl], influencing their photoluminescent properties.
- The study further revealed that solvent functional groups affect the hydrogen bonding strength with [SbCl], leading to changes in luminescent behavior and enhancing overall photoluminescence quantum yield to 95%.
Mutated channelopathy could play important roles in the pathogenesis of aldosterone-producing adenoma (APA). In this study, we identified a somatic mutation, 157-159delITE, and reported its immunohistological, pathophysiological and pharmacological characteristics. We conducted patch-clamp experiments on HEK293T cells and experiments on expression of aldosterone synthase (CYP11B2) and aldosterone secretion in HAC15 cells to evaluate electrophysiological and functional properties of this mutated .

Here, we observe that pretreatment with FGF23 protein into ischemia-reperfusion induced AKI mice ameliorates kidney injury by promoting renal tubular regeneration, proliferation, vascular repair, and attenuating tubular damage.

Clavulanate (CA) is a β-lactamase inhibitor that specifically targets class A, C, and D β-lactamases. In view of the presence of class B L1 β-lactamase, it is of interest to elucidate why TIM is valid for treatment.
