Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Effects of mixed microbial fermentation on the quality and metabolite profile of cassava leaf feed based on untargeted metabolomics

JSFA reports, EarlyView.
Abstract Background Cassava leaves are a major byproduct of cassava processing and have a low utilization rate. In this study, Lactiplantibacillus plantarum, Saccharomyces cerevisiae, and Bacillus subtilis were used for solid‐state fermentation of cassava leaves to improve their feed quality. Results After 48 h of fermentation, the feed pH decreased to

Atmospheric Corrosion Protection of LPBF Manufactured AlSi10Mg by Combining SiOx‐CVD and PDMS Grafting

Materials and Corrosion, EarlyView.
Hybrid SiOₓ‐CVD/PDMS ultrathin films mitigate atmospheric corrosion of additively manufactured AlSi10Mg. Electrochemical analyses show reduced corrosion currents, increased charge‐transfer resistance, and suppressed pitting due to diminished cathodic activity and limited oxygen and ion transport under NaCl exposure.

In Situ Atomic‐Scale Observation of Preferential Premelting at Oxide Crystal Defects

Small, EarlyView.
Under an external stimulus (e.g., an electron beam irradiation), premelting preferentially initiates at the planar defects in crystalline materials, thereby altering the local atomic and electronic structures. [Correction added on July 21, 2026, after first online publication: The graphical abstract figure has been updated.] ABSTRACT Under certain ...
