This study synthesized four asymmetric diglycolamides and demonstrated through experimental and DFT analyses that ligands with shorter and α-positioned alkyl branches, particularly L1, exhibit superior extraction efficiency for U(VI) in nitric acid systems by forming 1:1 or 2:1 complexes via electrostatic and partial covalent interactions.
This paper presents the development and validation of a harmonized single-column GC–FID method that enables efficient, routine quality control of five residual solvents across diverse diagnostic and therapeutic radiopharmaceutical products, thereby reducing analytical complexity in GMP radiopharmacies.
This study demonstrates that the high low-temperature CO oxidation activity of CuO/CeO₂ is maximized at 0.5 wt% Cu loading due to the formation of highly dispersed CuO nanoparticles where the Cu-O-Ce interface at the particle periphery serves as the active species.
This study elucidates how the chemistry of sodium- and potassium-based activators governs the reaction kinetics, microstructural evolution, and mechanical performance of alkali-activated electric arc furnace slag, revealing that while sodium systems offer higher early reactivity and strength, potassium systems provide sustained development, with both pore connectivity and gel organization playing critical roles beyond simple porosity.
This study demonstrates that an acid-resistant nanofiltration membrane effectively separates valuable Ni²⁺ and Co²⁺ ions from sulfuric acid waste generated during MWCNT purification, enabling the enrichment of metals for recovery and the direct reuse of regenerated acid in a closed-loop process that eliminates the need for neutralizing reagents.
This study presents a mechanically robust and highly selective fluorescent hydrogel, fabricated by integrating carboxyl/amino-rich carbon dots into a poly(vinyl alcohol)/chitosan dual-network matrix, which enables the sensitive visual detection of Fe³⁺ ions in aqueous environments through a static quenching mechanism.
By engineering copper substrates with a predominant (220) crystallographic facet to create a localized anion-rich microenvironment that drives the formation of a robust, inorganic-rich solid-electrolyte interphase, this study achieves stable, micromole-level lithium-mediated ammonia synthesis at an industrially relevant current density of 500 mA cm⁻².
This study employs a diffusion-based generative foundation model conditioned on thermodynamic stability to inverse-design solid-state fluoride-ion electrolytes in data-sparse chemical space, successfully identifying five stable Ni-based candidates through a hierarchical screening process that outperforms traditional prototype-based searches.
This study utilizes in situ electrochemical liquid-cell TEM and complementary techniques to reveal that shape-controlled zigzag Pt₃Fe nanowires undergo coupled morphological evolution and selective Fe depletion during the hydrogen evolution reaction, driven by electrostatic heterogeneity at high-curvature regions, thereby establishing catalyst morphology as a dynamic parameter in multicomponent electrocatalysis.
This study introduces a novel 2,4-dihydroxyacetophenone-based bis Schiff's base (BS) as a highly selective, AIEE-active "turn-off" fluorescent chemosensor for the rapid and reliable detection of toxic copper(II) ions in water samples, supported by experimental validation and DFT theoretical insights.
