Improved low-temperature dehydrogenation kinetics and cyclic stability of Mg(NH2)2-2LiH catalyzed by K2TiF6 additive

Li-Mg-N-H materials are promising for on-board hydrogen storage but limited by sluggish low-temperature kinetics and poor cycling. In this work, three dual-cation fluorides (K 2 TiF 6 , K 2 TaF 7 , K 2 NbF 7 ) were selected as catalysts for Mg(NH 2 ) 2 -2LiH, further K 2 TiF 6 do...

Investigation on Ti0.94Zr0.08Cr1.0Mn0.6−xFe0.4+x (x = 0, 0.1, 0.2, 0.3, 0.4) Alloys for 25 MPa Hydrogen Compression Materials

For hydrogen refueling stations, metal hydride compressors offer a safe and efficient alternative to mechanical systems. This work systematically investigates Ti0.94Zr0.08Cr1.0Mn0.6−xFe0.4+x (x = 0, 0.1, 0.2, 0.3, 0.4) alloys for primary hydrogen compression targeting 25 MPa. All...

A Scalable Low-Cost Epoxy-Based Porous Coating for High-Performance Radiative Cooling Prepared via a Pickering High-Internal-Phase-Emulsion Approach

Passive daytime radiative cooling (PDRC) technology with high solar reflectance and high infrared emissivity has been increasingly applied in green buildings. However, current PDRC designs are either high-cost or require additional multi-step fabrication processes, and both facto...

Study on Mechanochemical Activation-Enhanced Hydrochloric Acid Leaching of Rare Earth Elements from Roasted NdFeB Waste

NdFeB waste is an important rare earth secondary resource, and the current industrial practice primarily employs a hydrochloric acid preferential dissolution method to recover rare earth elements (REEs). However, approximately 1% of REEs (e.g., cerium oxide, neodymium oxide, pras...
