Oxygen: Highlights from the Papers Published in the Journal up to February 2024

open access: yesOxygen
Oxygen (O2) was discovered approximately 250 years ago (Contribution 1), a breakthrough accredited to at least three people: Antoine-Laurent de Lavoisier in France (Antoine Lavoisier), Carl Wilhelm Scheele in Sweden, and Joseph Priestley in England [...]

Jean-Antoine Chaptal (1756–1832) : premier chimiste disciple de Lavoisier

open access: yesComptes Rendus. Chimie
This article traces Antoine Chaptal’s career as a chemist and teacher from 1780 to 1798 and shows how in many ways, although distant from Antoine-Laurent de Lavoisier in Paris, he proved to be one of the first chemists to turn to the new chemistry ...

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

A 3D Lead Iodide Hybrid Based on a 2D Perovskite Subnetwork

open access: yesCrystals, 2021
Lead halide perovskites have emerged as promising materials for various optoelectronic applications. For photovoltaics, the reference compound is the 3D perovskite (MA)PbI3 (MA+ = methylammonium). However, this material suffers from instabilities towards

Cation‐Directed Host–Guest Assembly and Reversible Wheel to Cluster Interconversion in a 20‐Molybdate System

open access: yesChemistry – A European Journal, EarlyView.
The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

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 ...
