Multimodal Fluorescent MOF@BODIPY Platform: Bridging Sensing and Mechanistic Insight

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Hybrid metal–organic frameworks (MOFs) that integrate organic chromophores constitute powerful platforms for optical sensing by combining structural order with tunable photophysics. Incorporating photoresponsive chromophores into MOFs enables sensitive probing of guest–framework interactions through well‐defined luminescent signatures. Herein,

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

open access: yesChemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.

Targeting Cancer Cells With Self‐Assembled Ru‐Polysaccharide Photocatalyst for Visible‐Light‐Induced Activation of Prodrugs

open access: yesChemistry – A European Journal, EarlyView.
Self‐assembled photocatalyst Ru(Ada‐bpy)(bpy)2⊂HACD targets cancer cells and catalyzes the prodrug to drug upon exposure to visible light, providing spatially and temporally control in cancer cells. This strategy achieves efficient, controllable, and targeted activation of prodrugs within cancer cells, laying the foundation of effectively reducing the ...

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.

Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

High‐Strength, Fluorescent, Triboelectric Cellulose Hydrogel‐Derived Plastics Through Molecular Network Engineering for Energy Harvesting and Motion Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Multifunctional cellulose hydrogel‐derived plastics (FCBPs) are fabricated via a novel molecular network engineering strategy involving epoxy cross‐linking, solvent exchange, and hot‐pressing techniques. The resulting materials exhibit high mechanical strength, excellent thermal/solvent resistance, stable fluorescence, complete biodegradability, and ...

Sulphur-induced offsets in MC-ICP-MS silicon-isotope measurements

open access: yes, 2009
Sample preparation methods for MC-ICP-MS silicon-isotope measurements often involve a cation-exchange purification step. A previous study has argued that this would suffice for geological materials, as the occasional enrichment of anionic species would ...

Stable, Reusable Copper‐Bispidine Catalysts on Agarose With Diffusion‐Limited Turnover: When Immobilization is not Covalent

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Epoxy‐activated agarose beads as support for copper(II)‐bispidine complexes provide reusable heterogeneous catalysts for styrene aziridination with negligible copper leaching. Immobilization occurs largely through noncovalent interactions. Catalyst loading strongly governs performance by balancing active‐site density, accessibility, and mass transport.
