    Article Snippet: The three-dimensional (3D) semiconductor/noble metal composite substrates for surface-enhanced Raman scattering (SERS) have garnered increasing interest due to their excellent optical and chemical properties, as well as the capacity to trigger both electromagnetic mechanism (EM) and chemical mechanism (CM) simultaneously.. In this work, a facile 3D urchin-like K2Ti8O17/Ag nanoparticles (Ag NPs) composite substrate is designed for multi-purpose SERS sensing.. K2Ti8O17, as a dielectric medium, improves the electric field environment around Ag NPs, which is consistent with finite-different time domain (FDTD) results, and enhances the SERS performance of the K2Ti8O17/Ag composite substrate.

The exchange membranes, which are the core components of RED systems, especially in the investigation of composite membrane systems, remain a challenge by balancing the key requirements of better compatibility and sufficient stability, ease of fabrication, etc.. In view of the excellent compatibility and stability of forest biomass membrane materials, this work reports a two-dimensional (2D) lamellar regenerated cellulose (RC) composite with a threedimensional (3D) network of bacterial cellulose membrane doped with alkali lignin (BC-AL) heterogeneous membrane.

    Article Title: Metal-Support Interaction and Tip-Enhanced Electric Field Effect Co-Enhancing Oxygen Species Adsorption/Enrichment for Efficient Electrooxidation of Plastic Waste Derived Alcohol into Glycolic Acid
    Article Snippet: The limited catalytic activity and weaker stability caused by the restricted adsorption capacity of reactive oxygen species (*OH) have hindered the further development of electrocatalytic upgrading polyethylene terephthalate (PET) waste into valuable C2 chemicals, which is crucial in addressing the plastic pollution issue.. Herein, Pd@Ni (OH)2-NiO catalyst was synthesized based on the concepts of metal-support interaction and tip-enhanced electric field effect, demonstrating remarkable activity (0.60 V vs. RHE, 300 mA cm 2) and stability (250 h) for electrocatalytic upgrading PET plastic waste into glycolic acid.. A significant charge transfer occurs between metal Pd and supports Ni(OH)2-NiO due to the metal-support interaction, generating the electron-deficient Pdδ+ sites.

    Article Snippet: Bulk metallic glasses (BMGs) have been widely used in precise manufacturing industry, and their surface quality is one of the key properties for practical applications.. Electropolishing (EP) is an effective technique to improve surface roughness for metal materials with good precision and no tool wear.. In this work, the feasibility of electropolishing nonplanar surfaces with planar electrode is verified by multi-physics simulation.
