As global nuclear energy scales up, the annual output of low-to-medium-level radioactive tributyl phosphate (TBP) and n-dodecane organic solvents from spent fuel processing grows. To address this problem, the serine grafted silica coated nanoscale zero-valent iron (Ser-SiO@nZVI) is synthesized and used as a Fenton-like catalyst. Ser-SiO@nZVI is analyzed through various characterization techniques.

Electrocatalytic acetylene semi-hydrogenation offers a sustainable and energy-efficient alternative to conventional thermocatalytic methods, yet remains challenged by competing side reactions, including hydrogen evolution, over-hydrogenation, and carbon-carbon coupling. Here, the transformation of 2D van der Waals crystalline CuTe nanosheets (c-CuTe NSs) into oxygen-doped amorphous analogues (a-CuTe NSs) via controlled air calcination is reported. The resulting a-CuTe NSs feature a disordered Cu coordination network and deliver an ethylene Faradaic efficiency of 91.

Interfacial water serves as both a proton donor and a competitor for active sites at the copper-catalyst interface in the electrochemical CO reduction reaction (CORR). However, its precise impact on C product selectivity remains debatable. Here, through the utilization of Raman spectroscopy and theoretical calculations, we have discovered that the population of K cation hydrated water (K-HO) rises concurrently with the increase of C yield on atomically flat model Cu() single crystal surfaces.

The contact time of the droplet impacting on solid surfaces can be markedly reduced by 40% to 50% by breaking the symmetric behaviors with the help of the surface structures and motion, which is crucial to diverse applications involving anti-icing, anti-erosion, self-cleaning, etc. Herein, it is interesting to note that the contact time can be further decreased up to 60% on a moving ridge surface because of corresponding synergy, inspired by flying insects or wind-dispersal seeds. In the present work, the synergistic mechanisms of the reduction in contact time have been revealed by analyzing the 3 basic features, called Leaf-type, Ear-type, and Butterfly-type, according to their morphological and dynamical behaviors.

While ionic thermoelectric (i-TE) materials can exhibit high thermopower, most of them rely on the addition of a large amount of ionic liquids (IL). This study demonstrates significant improvements in the thermopower of ionogels composed of poly(vinylidene fluoride--hexafluoropropylene) (PVDF-HFP) and 1-ethyl-3-methylimidazolium chloride (EMIM:Cl) through the asymmetric doping of sodium chloride (NaCl). This improvement results from the coupling of the preintroduced ion concentration difference and temperature difference, which reduces the cation migration barrier in the direction of thermal diffusion, leading to significantly enhanced performance compared to symmetric doping.

While nonaqueous cosolvents alleviate hydrogen evolution reaction and dendritic growth in aqueous zinc (Zn) metal batteries (ZMBs), persistent HO activity at Zn|electrolyte interfaces originating from unregulated ion distribution leads to premature failure. Here, an electric field-guided ion orchestration (EF-IO) strategy is proposed, leveraging cation interfacial modifiers to reconfigure electric double layers (EDLs) and solvation configurations. Interfacial simulations combined with experimental investigations verify that the ion-orchestrated-EDL synergistically diversifies Zn/Na solvation configurations and homogenizes localized electric fields, thereby forming an organic-inorganic gradient solid electrolyte interphase (SEI) that suppresses parasitic reactions.

Electrocatalytic alkyne semi-hydrogenation (EASH) powered by renewable electricity using water as a hydrogen donor provides a sustainable alternative to conventional thermocatalysis. However, the current EASH systems predominantly follow hydrogen atom transfer (HAT) pathways, which are prone to over-hydrogenation and at the same time compete with the hydrogen evolution reaction. In this work, we report a proton-coupled electron transfer (PCET) mechanism enabled on Cu(111) surface for highly efficient and selective EASH.

The free-energy-based lattice Boltzmann method has emerged as a reliable tool for simulating multiphase flows, but its application to small droplet interactions with surrounding flows is hindered by the issue of spontaneous droplet shrinkage. In contrast to previous analyses based on phase-field theory, we investigate spontaneous droplet shrinkage within the framework of the lattice Boltzmann equation for a free-energy-based model and identify that local density continues to evolve even after the system reaches equilibrium. To address this undesired density evolution, we introduce a mass correction formulated as a Laplacian term, ensuring that local mass conservation is improved without sabotaging global mass conservation.

An investigation of the characteristics of the turbulent-nonturbulent interface (TNTI) in spatially developing compressible turbulent boundary layers is performed by using a direct numerical simulation. The mean thicknesses of the TNTI layer δ_{TNTI} is approximately 13η_{ref} (η_{ref} is the Kolmogorov scale taken from a location of 0.3δ_{ref} from the outer edge of the TNTI layer, where δ_{ref} is the nominal thickness of the boundary layer) and the two components of the TNTI layer, viscous superlayer δ_{VSL} and turbulent sublayer δ_{TSL}, are approximately 3.

The heterogeneity (acid sites) and stability (redox sites) of metal loss on metal-acid catalyst surfaces are the fundamental factors for the "trade-off" effect between activity and selectivity in the catalytic process with NH as the activation precursor. However, the molecular-level impact of these surface characteristics on catalytic performance remains unclear and contentious. Herein, we propose a straightforward decomposition temperature control method, which operates below the single-layer dispersion threshold of solid sulfate/nitrate precursors.

Vapor bubbles produced by long-pulsed laser often have complex non-spherical shapes that reflect some characteristics of the laser beam. The transition between two commonly observed shapes - namely, a rounded pear-like shape and an elongated conical shape - is studied using a new computational model that combines compressible multiphase fluid dynamics with laser radiation and phase transition. Two laboratory experiments are simulated, in which Holmium:YAG and Thulium fiber lasers are used respectively to generate bubbles of different shapes.
