Cation‐Framework‐Preserving Oxygen‐Vacancy Engineering for Broadband Infrared Emission in High‐Entropy Spinel Oxides

ABSTRACT High‐temperature radiative ceramics require broadband infrared emission and stable structures, but the defects that enhance emission can also weaken oxide lattices. Here, we regulate oxygen vacancies in (MnCrFeNiCu) 3 O 4 , a high‐entropy spinel oxide (HEO), by vacuum an...

Friction-reducing and wear-resistant cellulose-epoxy composite coating based on fish-scale biomimetic structures

Epoxy resin (EP) coatings are attractive for surface protection because of their strong adhesion and chemical stability; however, their intrinsic brittleness and limited tribological durability, together with filler agglomeration and weak filler–matrix interfaces, restrict their...

Energy-saving hydrogen production coupled with PET-derived ethylene glycol oxidation: Reaction mechanisms, catalyst design, and reactor engineering

Abstract The growing accumulation of poly(ethylene terephthalate) (PET) waste and the increasing demand for clean hydrogen call for integrated electrochemical strategies. Ethylene glycol oxidation reaction (EGOR), derived from PET hydrolysis, offers a thermodynamically favorable...

Zn-Modified MoS2 Catalyst for Efficient CO2 Hydrogenation to CH3OH

Abstract Hydrogenation of carbon dioxide (CO2) to methanol (CH3OH) using hydrogen produced from renewable energy sources is a promising pathway for carbon recycling and energy storage. Molybdenum disulfide (MoS2), with its typical layered structure, holds significant industrial p...
