Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

Chemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Sustainable Synthesis of 4,7‐Dihydro‐4,7‐ethano‐2H‐isoindoles—Key Building Blocks to Benzoporphyrins

Chemistry – A European Journal, EarlyView.
A facile and sustainable route to isoindole derivatives—key benzoporphyrin precursors—brings high‐ and low‐symmetry benzoporphyrins closer to practical application. ABSTRACT Benzoporphyrins, π extended porphyrin analogues, exhibit remarkable potential for optoelectronic and theragnostic applications, yet have remained largely confined to fundamental ...

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Universal and Normalized Regeneration of Heterogeneous Spent LiFePO4 via Mechanochemical Delithiation and Flash Relithiation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We propose a universal “x → 0 → 1” regeneration route: mechanochemical delithiation converts spent LixFePO4 of any degradation level to FePO4, erasing batch variance; 35‐s flash relithiation yields uniform LiFePO4 with near‐identical capacity, suppressing grain growth and cutting energy andtime by >90% versus furnace sintering, overcoming unpredictable

Redistributing Cobalt and Tungsten From WC–Co Soft Scrap Toward Sustainable Cathode and Coating Materials for Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...
