Mechanistic Insight into H2S‐Induced Fluorescence Quenching in a Robust Metal–Organic Framework

open access: yesSmall, EarlyView.
An ultramicroporous Zn‐based metal‐organic framework, MFM‐520, enables reversible hydrogen sulfide adsorption and selective fluorescence sensing. Confinement of H2S within the pores perturbs ligand‐centered excited states through weak host‐guest interactions, enhancing non‐radiative decay pathways.

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Synthesis of Samarium‐incorporated X‐ray‐sensitive nanoparticles and hydrogels: Diverse applications in radiation monitoring and dynamic information display

open access: yesSmart Molecules, EarlyView.
Sm3+‐doped α‐NaLuF4 and β‐NaLuF4 were synthesized. The X‐ray‐activated persistent luminescence abilities and afterglow properties can be well controlled. Sm3+‐doped β‐NaLuF4 exhibits remarkable afterglow ability. The hexagonal β‐NaLuF4:3%Sm3+‐incorporated hydrogel can be further programmed with other types of hydrogels to enable tunable emission ...

Y4Ni0.71Ag1.29: Expanding the Boundaries of the Gd4RhIn Structure Type

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
A first representative of the Gd4RhIn type with three transition metals. The new ternary compound Y4Ni0.71Ag1.29 has been prepared by arc melting the elements under inert atmosphere. Subsequent annealing at 800°C for 2 weeks yielded crystals of sufficient quality for structure determination by single‐crystal X‐ray diffraction.

Organotitanyl “TiCp” Fragment Capping the Bowl‐Shaped Unit in the Ternary Anion [(Cp)Ti(Sn3Bi3)]2−

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
A novel ternary anion, [(η5‐Cp)Ti(Sn3Bi3‐κ3)]2− composed of a cyclopentadienyl titanium fragment coordinated by a Sn3Bi3 bowl‐shaped cluster unit, is reproted. Unlike homoatomic nine‐atom clusters of heavier tetrel elements, which retain their identity upon dissolution, intermetalloid clusters are not formed directly from ternary alkali‐metal alloys in

Gepta‐EX: a multi‐channel germanium detector for X‐ray absorption fine structure

open access: yesJournal of Synchrotron Radiation, EarlyView.
Gepta‐EX is a compact seven‐channel high‐purity germanium detector designed to deliver high‐resolution fluorescence X‐ray absorption fine‐structure measurements at photon energies where silicon detectors become effectively transparent. It provides excellent energy resolution across a broad energy range, avoids silicon escape‐peak artifacts, and offers ...

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

open access: yesJournal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Morphological Control of Aurophilic Chains of Gold(I) Dithiolate Dimers With Alkali and Alkali Earth Cations

open access: yesChemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Luminescent coordination polymers of Group 1 (Li, K, Cs) and 2 (Mg─Ba) cations with gold(I) iso‐maleonitriledithiolate ({Au2[S2C = C(CN)2]}2−) units were prepared; 1‐D aurophilic chains are present in all cases. The structures strongly depend on cation charge and size, with N‐cyano coordination observed in the Gp 1 and larger Gp 2 cations. Increasingly
