DOI: 10.1002/adfm.202503692

Abstract: Metal oxyhydroxides (MOOHs) as the active phase of transition metal‐oxide (TMOs) electrodes in the oxygen evolution reaction (OER) are limited by unsatisfactory electrochemical activity and stability during high‐current conditions. Herein, the heterostructure of high‐valent IrOx… read more here.

DOI: 10.1002/aenm.202403004

Abstract: Ni‐based electrocatalysts are considered to be significantly promising candidates for electrocatalytic urea oxidation reaction (UOR). However, their UOR activity and stability are severely enslaved by the inevitable Ni group self‐oxidation phenomenon. In this study, the… read more here.

DOI: 10.1016/j.cej.2017.10.131

Abstract: Abstract Over the past two decades, groundwater contaminated with chlorinated organic compounds has been successfully remediated via reductive dehalogenation by zero-valent iron. While reductive defluorination of the environmentally persistent perfluorooctanoic acid (PFOA) by Fe 0… read more here.

DOI: 10.1016/j.cej.2019.122688

Abstract: Abstract Acidic functionalized polymer-MIL-101 composite membrane were considered as a promising material for the electrodialytic separation of targeted bi-valent metal ion from industrial waste water. Architectural strategy for these specific selective membrane was based on… read more here.

DOI: 10.1021/acs.inorgchem.2c00685

Abstract: Iron complexes with nitrido ligands are of interest as molecular analogues of key intermediates during N2-to-NH3 conversion in industrial or enzymatic processes. Dinuclear iron complexes with a bridging nitrido unit are mostly known in relatively… read more here.

DOI: 10.1021/acssensors.2c01340

Abstract: We present the development of electrochemical impedance spectroscopy (EIS)-based biosensors for sensitive detection of SARS-CoV-2 RNA using multi-valent binding. By increasing the number of probe–target binding events per target molecule, multi-valent binding is a viable… read more here.

DOI: 10.1038/s41467-025-57568-1

Abstract: Although complexes with monatomic zero-valent main group centers have been reported, diatomic zero-valent complexes are extremely rare and all previously reported examples were stabilized by either carbene or silylene ligands. Here, we present the isolation… read more here.

DOI: 10.1093/jpids/piac117

Abstract: Abstract Background Pneumococcal conjugate vaccines (PCVs) effectively reduce infection and asymptomatic carriage of Streptococcus pneumoniae vaccine serotypes. In 2016, Belgium replaced its infant PCV13 program by a 4-year period of PCV10. Concomitantly, S. pneumoniae serotype… read more here.
