Solar-Driven Cr(VI) Detoxification via a Holmium-Modulated In2S3 Strategy A Rare-Earth Approach to Sustainable Photocatalysis 来源：ACS PublicationsThe photocatalytic reduction of hexavalent chromium Cr(VI) under visible light has gained considerable attention due to its relevance to environmental remediation. In this study, Ho-doped In2S3 photocatalysts were synthesized via a photodeposition method to improve the Cr(VI) reduction performance. The characterizations of the synthesized catalysts were performed using various techniques, including X-ray diffraction, scanning electron microscopy, tran...

来源：ACS PublicationsRare-earth metal and actinide based thin films are promising materials for applications ranging from optoelectronics to energy storage and conversion. While chemical vapor deposition (CVD) exhibits substantial advantages over physical vapor deposition, CVD processes rely on precursor design to achieve a high volatility, appropriate stability, and controllable reactivity. This is particularly challenging for rare-earth metals and actinides since they primarily form ionic bonds. Despite the challenges, the number of rare-earth metal and actinide CVD precursors has greatly incr...

来源：ACS PublicationsOpen-shell nanographenes have attracted significant attention due to their structurally tunable spin ground state. While most characterization has been conducted on weakly interacting substrates such as noble metals, the influence of magnetic surfaces remains largely unexplored. In this study, we investigate how TbAu2, a rare-earth-element-based surface alloy, affects the magnetic properties of phenalenyl (or [2]triangulene (2T)), the smallest spin-1/2 nanographene. Scanning tunneling spectroscopy (STS) measurements reveal a striking contrast: while 2T on Au(111) exhibits a ...

来源：ACS PublicationsThe rising demand for Rare Earth Elements (REEs) highlights the need for sustainable cost-effective extraction methods, particularly from secondary sources, such as coal-related materials. Recovering REEs from these resources supports domestic supply security while reducing waste. This study evaluates the techno-economic feasibility of producing RE-hydroxide from coal-related materials using a chemical recycling process that recovers 90% of reagents, including 2.5 tons of soda ash and 9.5 tons of water. The process requires $35 million in initial capital investment and yield...
