Nanolaminated materials are important because of their exceptional properties and wide range applications. Here, we demonstrate a general approach to synthesize series Zn-based MAX phases Cl-terminated MXenes originating from the replacement reaction between phase late transition metal halides. The is top-down route that enables transitional element atom (Zn in present case) occupy A site pre-existing structure. Using this Zn molten ZnCl2 Al precursors (Ti3AlC2, Ti2AlC, Ti2AlN, V2AlC), novel...
With the potential wide uses of nanoparticles such as carbon nanotubes in biomedical applications, and growing concerns nanotoxicity these engineered nanoparticles, importance nanoparticle-protein interactions cannot be stressed enough. In this study, we use both experimental theoretical approaches, including atomic force microscope images, fluorescence spectroscopy, CD, SDS-PAGE, molecular dynamics simulations, to investigate single-wall (SWCNTs) with human serum proteins, find a...
Photocross-linkable Au nanoparticles are prepared through surface decoration of photolabile diazirine moieties. Both in vitro and vivo studies indicate that the light-triggered cross-linking can dramatically shift plasmon resonance to near-infrared regions, which consequence remarkably enhances their efficacy for photothermal therapy photoacoustic imaging tumors vivo.
Noble metal-based nanomaterials have shown promise as potential enzyme mimetics, but the facet effect and underlying molecular mechanisms are largely unknown. Herein, with a combined experimental theoretical approach, we unveil that palladium (Pd) nanocrystals exhibit facet-dependent oxidase peroxidase-like activities endow them excellent antibacterial properties via generation of reactive oxygen species. The efficiency Pd against Gram-positive bacteria is consistent extent their enzyme-like...
We demonstrate fabrication of a two-dimensional Hf-containing MXene, Hf3C2Tz, by selective etching layered parent Hf3[Al(Si)]4C6 compound. A substitutional solution Si on Al sites effectively weakened the interfacial adhesion between Hf-C and Al(Si)-C sublayers within unit cell compound, facilitating subsequent etching. The underlying mechanism Si-alloying-facilitated process is thoroughly studied first-principles density functional calculations. result showed that more valence electrons...
Effective and selective removal of 99TcO4– from aqueous solution is highly desirable for both waste partitioning contamination remediation purposes in the modern nuclear fuel cycle, but significant challenge. We report here a hydrolytically stable radiation-resistant cationic metal–organic framework (MOF), SCU-101, exhibiting extremely fast kinetics, exceptional distribution coefficient, high sorption capacity toward TcO4–. More importantly, this material can selectively remove TcO4–...
Amine grafting on MOFs greatly enhances the adsorbability of Cr-MIL-101 towards U(<sc>vi</sc>) from an aqueous solution, and enhancement depends coverage flexibility grafted amino group.
Metal-organic frameworks (MOFs) based on zirconium phosphonates exhibit superior chemical stability suitable for applications under harsh conditions. These compounds mostly exist as poorly crystallized precipitates, and precise structural information has therefore remained elusive. Furthermore, a zero-dimensional phosphonate cluster acting secondary building unit been lacking, leading to poor designability in this system. Herein, we overcome these challenges obtain single crystals of three...
Searching for new chemically durable and radiation-resistant absorbent materials actinides their fission products generated in the nuclear fuel cycle remain highly desirable, both waste management contamination remediation.

This unique structural...
Uranium is not only a strategic resource for the nuclear industry but also global contaminant with high toxicity. Although several strategies have been established detecting uranyl ions in water, searching new uranium sensor material great sensitivity, selectivity, and stability remains challenge. We introduce here hydrolytically stable mesoporous terbium(III)-based MOF compound 1, whose channels are as large 27 Å × 23 equipped abundant exposed Lewis basic sites, luminescence intensity of...
99Tc is one of the most problematic radioisotopes in used nuclear fuel owing to its combined features high fission yield, long half-life, and environmental mobility. There are only a handful functional materials that can remove TcO4- anion from aqueous solution identifying for new, stable with anion-exchange capacities, fast kinetics, good selectivity remains challenge. We report here an 8-fold interpenetrated three-dimensional cationic metal-organic framework material, SCU-100, which...
Many environmental pollutants inherently exist in their anionic forms and are therefore highly mobile natural water systems. Cationic framework materials that can capture those desirable but scarcely reported. Here we present a mesoporous cationic thorium-based MOF (SCU-8) containing channels with large inner diameter of 2.2 nm possessing high surface area 1360 m2 g-1. The anion-exchange properties SCU-8 were explored many anions including small oxo like ReO4- Cr2O72- as well organic dyes...
