Many eukaryotes acquired chloroplasts by endosymbiotic acquisition of photosynthetic bacteria or already-domesticated chloroplasts from other eukaryotes. However, the ciliate Mesodinium rubrum acquires the nucleus of a photosynthetic eukaryote, as well as its chloroplast, resulting in dramatic metabolic remodelling in the ciliate.

Atomically precise gold nanoclusters have shown great promise as model electrocatalysts in pivotal electrocatalytic processes such as the hydrogen evolution reaction (HER) and carbon dioxide reduction reaction (CORR). Although the influence of ligands on the electronic properties of these nanoclusters is well acknowledged, the ligand effects on their electrocatalytic performances have been rarely explored. Herein, using [Au(SR)] nanoclusters as a prototype model, we demonstrated the importance of ligand hydrophilicity hydrophobicity in modulating the interface dynamics and electrocatalytic performance.

Bismuth-layered ferroelectric nanomaterials exhibit great potential for piezo-photocatalysis. However, a major challenge lies in the difficulty of recovering the catalytic powders, raising concerns regarding secondary pollution of water. In this work, a novel hierarchical porous ferroelectric ceramic containing {110} surface-exposed BiNdTiO (BIT-Nd) nanosheet arrays is grown on a porous ceramic matrix for efficient and recyclable piezo-photocatalysis.

This work investigates the solid-state reaction between iridium and zirconium carbide, resulting in the formation of carbon and ZrIr-an intermetallic compound of great interest for modern high-temperature materials science. We have found a transition of kinetic regimes in this reaction: from linear kinetics (when the chemical reaction is a limiting stage) at 1500 and 1550 °C to 'non-parabolic kinetics' at 1600 °C. Non-parabolic kinetics is characterized by the thickness of the product layer being proportional to a power of time less than 1/2.

Electrochemical oxidation of small molecules shows great promise to substitute oxygen evolution reaction (OER) or hydrogen oxidation reaction (HOR) to enhance reaction kinetics and reduce energy consumption, as well as produce high-valued chemicals or serve as fuels. For these oxidation reactions, high-valence metal sites generated at oxidative potentials are typically considered as active sites to trigger the oxidation process of small molecules. Isolated atom site catalysts (IASCs) have been developed as an ideal system to precisely regulate the oxidation state and coordination environment of single-metal centers, and thus optimize their catalytic property.

To enable highly efficient in situ hydrogen release from methanol/water reforming at lower temperature, the integration of solar-energy offers a promising approach to activate methanol/water and substantially lower the activation energy of this reaction. Herein, we present a novel dual-vacancy defective hollow heterostructure derived from Metal-Organic Frameworks, featuring abundant surface hydroxyl groups and S/O vacancies, for photothermal-promoted methanol solution reforming into hydrogen. The [In2S3-x/In2O3-x](OH)y exhibits exceptional photothermal H2 evolution activity, achieving a production rate of 215.
