Small Structures, Volume 5, Issue 8, August 2024.The inner diameter of the lumen is enlarged by etching the halloysite nanotubes with an acidic solvent to increase the loading capacity of the iron–platinum nanoparticles and anticancer drugs. By adjusting the direction of the magnetic field with 3D stress and pressure, the increased saturation magnetization of the material can effectively achieve ...

Bulk Nanostructured Silicide Thermoelectric Materials by Reversible Hydrogen Absorption–Desorption
Small, Volume 20, Issue 21, May 23, 2024.For the first time, the production of bulk nanostructured silicide thermoelectric materials by a reversible hydrogen absorption–desorption process is demonstrated. The advanced synthesis process enables microstructure refinement of more than two orders of magnitude, from around 50 µm in the initial ingot to 100–200 nm.

Novel Fe‐Based Amorphous Brazing Foils in the Quinary System Fe–Ni–Cr–Si–B
Advanced Engineering Materials, Volume 26, Issue 4, February 2024.Flexible Fe‐based brazing foils are designed by means of thermodynamic databases in the quinary system Fe–Ni–Cr–Si–B and the atomic mismatch factor λ. Thermal and microstructure characterization indicate a nanocrystalline or amorphous structure of some Fe‐based foils produced in the melt‐spin process.

Direct Recycling of Hot‐Deformed Nd–Fe–B Magnet Scrap by Field‐Assisted Sintering Technology
Advanced Energy and Sustainability Research, Volume 5, Issue 1, January 2024.Electric current‐assisted sintering (ECAS) techniques have the potential to directly densify scrap Nd–Fe–B magnet powder into new magnets. A systematic experimental study is performed to generate new magnets from scrap material, and the samples' magnetic properties are measured.
