Mesoporous Hollow Carbon Spheres/Nanofibers Anchored With Conductive Bimetallic for Efficient Microwave Absorption

Rare Metals, EarlyView.
ABSTRACT To break electromagnetic wave absorption (EMA) tech's single‐attenuation bottleneck, enhancing multi‐wave absorption synergy in composites is key for microstructure design. This study uses mesoporous hollow carbon spheres to make metal nanospheres with cobalt, iron, and nickel nanoparticles, then encapsulates them via electrospinning into a ...

Enhanced Low‐Frequency Microwave Absorption and Corrosion Resistance of FeSiAl Using Low‐Melting‐Point Glass Phase Coatings

Rare Metals, EarlyView.
ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

From Ministries of Food to National Food System Committees: A Global Mapping and Typology of Multisectoral Food System Governance Institutions

Sustainable Development, EarlyView.
ABSTRACT Transforming the ways food systems are governed is key to achieving better social, environmental, and economic outcomes, all crucial to sustainable development. Strong multisectoral governance is critical to achieving this, but there is little evidence on the structure and function of governance mechanisms in this context.
