PdMoW trimetallene facilitates the electrooxidation of ethanol in alkaline electrolyte with high efficiency and C2 selectivity.

Against the backdrop of global carbon neutrality target driving the transformation of energy structure, alcohol fuel cells (AFCs) show great application potential; However, the sluggish kinetics of their anodic alcohol oxidation reaction hinders the commercialization of AFCs. Metallene is a novel 2D material with potential application prospect in the field of electrocatalysis. In this paper, PdMoW trimetallene has been successfully produced by a one-pot wet-chemical method, which displays a unique two-dimensional curved ultrathin graphene structure.

Molecular Motor Matrix-Based Augment Heat Dissipation Strategy Affording Ultrahigh-PCE J-Aggregates for Potentiate Cancer Photothermal Immunotherapy.

The photothermal conversion efficiency (PCE) stands as a pivotal determinant in the therapeutic efficacy of photothermal nanoagents (PTNAs) within the context of photothermal therapy (PTT). The dearth of universal strategies to greatly enhance PCE has markedly curtailed the practical deployment of PTNAs. Now this problem is addressed by proposing a universal approach founded on molecular rotors and J-aggregates, "highly efficient molecular motor matrix", to greatly elevate the PCE of traditional PTNAs.

Investigation on Reactivity and Selectivity of Electrocatalytic CO Reduction in Photochemically Synthesized Ag and Alloyed AgCu and AgCu Nanoclusters.

Atomically precise nanoclusters are desirable for understanding the structure-property relationships in the electrocatalytic CO reduction reaction (eCORR), but suitable related models are lacking, especially those of low- or zerovalent noble metal nanoclusters and their alloyed analogues. We first developed a photochemical method toward silver nanocluster Ag(4- BuPhC≡C)(Dpppe)(SbF) ( -) and then related copper-doped alloyed nanocluster AgCu(4- BuPhC≡C)(Dpppe)Cl(SbF) ( -). Herein, we present a larger alloyed nanocluster, AgCu(4- BuPhC≡C)(Dpppe)(SbF) ( -) and investigate the relationship between the structures and the eCORR performance of those related nanoclusters.

Bio-Transport Regulation Inspired 5-Fluorouracil Keto to Enol Tautomerism Achieving High Proton Conductivity.

The strategic modulation of proton transport kinetics and precise control of migration energy barriers in metal-organic frameworks (MOFs) are essential for developing next-generation proton conductors. Inspired by biological proton channels, this study introduces a dynamic regulation strategy by keto-enol tautomerism to reconcile the intrinsic trade-off between low activation energy (E) and sustained proton mobility. We successfully construct a hierarchical proton conductive system (denoted as FU@MOF-808-SOH) by integrating 5-fluorouracil (5-FU) molecules into sulfonic-functionalized MOF-808 through a two-step post-synthetic modification.

Bandgap modulation and mitochondria-targeted AIE luminogens for combinational phototherapies of tumor through synergistic cell apoptosis and pyroptosis.

And their luminescence properties can be modulated by adjusting the strength of the D-A structure.

Haloxylon ammodendron plantations: enhancing multi-trophic arthropod diversity and soil multifunctionality in arid deserts.

The conversion of natural desert vegetation to artificial sand-fixing vegetation significantly impacts the diversity of ground arthropods across various trophic levels. Consequently, this change modifies the structure and function of arthropod-dominated soil food webs, thereby influencing soil multifunctionality. In this study, we set up a vegetation gradient in the desert-oasis ecotone of Zhangye Oasis, Hexi Corridor, spanning from natural desert vegetation (mobile and fixed sandy dunes) to artificial fixed sandy vegetation (5-, 10-, 20- and 30- year-old Haloxylon ammodendron plantations).

Influence of hydrogen bonding on twisted intramolecular charge transfer in coumarin dyes: an integrated experimental and theoretical investigation.

Twisted intramolecular charge transfer (TICT) is a critical mechanism influencing the emission efficiency and stability of fluorescent materials, thereby playing a pivotal role in the design of highly fluorescent and stable dyes. Although substantial research has concentrated on the role of intermolecular hydrogen bonding in excited-state dynamics, the impact of intramolecular hydrogen bonding has not been thoroughly investigated. To elucidate the solvent polarity dependence of C7 and C30, we employed the Kamlet-Taft and Catalán 4P models in conjunction with steady-state and transient absorption spectroscopy, complemented by time-dependent density functional theory (TDDFT) calculations.

Electrolyte-mediated Cu/Cu ratio control in Cu/graphene catalysts for divergent CO electroreduction pathways.

The electrochemical CO reduction reaction (CORR) to multi‑carbon products offers a promising route for sustainable fuel production, yet achieving high selectivity remains challenging due to the complex interplay between catalyst structure and reaction pathways. Here, we report a rational design of Cu-CuO/graphene (Cu/G) composites with tunable Cu/Cu ratios via electrolyte-mediated electrochemical synthesis. By varying tetraalkylammonium/phosphonium electrolytes (TBABF, TBAPF, TBACFSO, TBPBF), we precisely control Cu oxidation states, as validated by the results of X-ray absorption fine structure (XAFS), X-ray diffraction (XRD), and high-resolution transmission electron microscope (HRTEM).
