Ammonia leaching can achieve selective recovery of nickel and molybdenum without aluminum extraction from spent hydrodesulfurization catalyst. In this study, a method for selective nickel extraction by LIX84 from ammoniacal leach liquor is proposed. After a two-stage countercurrent extraction, 99.977% Ni was extracted, while 0.096% Mo, 0.431% Al an...

Recent efforts have shown that acid mine drainage precipitates (AMDp) may be a promising source of rare earth elements and critical materials (REE/CM). To better understand this resource, several particle characterization studies were conducted on AMDp samples from three AMD treatment sites in Northern and Central Appalachia. This work included the...

The development of novel and operationally simple synthetic routes to carbene-metal-amido (CMA) complexes of copper, silver and gold relevant for photonic applications are reported. A mild base and sustainable solvents allow all reactions to be conducted in air and at room temperature, leading to high yields of the targeted compounds even on multig...
Despite efforts in producing nanoparticles with tightly controlled designs and specific physicochemical properties, these can undergo massive nano-bio interactions and bioprocessing upon internalization into cells. These transformations can generate adverse biological outcomes and premature loss of functional efficacy. Hence, understanding the intr...
In gold smelting industry, coexisting of arsenic (As) and antimony (Sb) in gold-bearing sludge is a serious issue for the smelting process. This study employed a two-stage leaching methods to selective extract arsenic and antimony from gold-bearing sludge. Arsenic was firstly removed through NaOH leaching, following by Na2S-NaOH leaching to remove ...

Atomic layer deposition (ALD) combined with self-assembled monolayer (SAM) passivation allows selective deposition on patterned substrates at the nanoscale, enabling bottom-up material fabrication for various applications. Selective chemisorption of 1-octadecanethiol (ODT) on Cu over SiO2 is exploited to achieve area selective deposition (ASD). Alt...
A series of boron doped magnetic zirconium catalysts were developed for the selective transfer hydrogenation of biomass-derived furfural (FFR) into furfuryl alcohol (FA) using 2-propanol as hydrogen source and solvent. Full characterizations with XRD, SEM, TG, Py-IR, NH3-TPD, and CO2-TPD techniques were undertaken to uncover structural properties o...
