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.

Titanium migration and bone response in loaded osseointegrated implants: ESEM‐EDX analysis in Macaca fascicularis

Journal of Periodontology, EarlyView.
Abstract Background Titanium nanoparticle (TP) migration into peri‐implant bone may influence osseointegration. It remains unclear how loading protocols may affect TP distribution. This study aimed to detect TP in the bone around implants undergoing different loading protocols in Macaca fascicularis.

Superconductivity induced by Ni doping in BaFe$_2$As$_2$

, 2008
A series of 122 phase BaFe$_{2-x}$Ni$_x$As$_2$ ($x$ = 0, 0.055, 0.096, 0.18, 0.23) single crystals were grown by self flux method and a dome-like Ni doping dependence of superconducting transition temperature is discovered.

Design, Synthesis, Cytotoxicity Assessment, and Molecular Docking of Novel Triazolopyrimidines as Potent Cyclin‐Dependent Kinase 4 Inhibitors

ChemistryOpen, EarlyView.
A novel series of 1,5‐dihydro‐[1,2,4]triazolo[4,3‐a]pyrimidines (5a–g) is synthesized and evaluated as potential CDK4 inhibitors. Compounds 5c and 5d exhibit strong cytotoxicity toward HepG2 and MCF‐7 cells with IC50 ≈ 1–2 µM, comparable to doxorubicin.
