Summary: Potentiostatic anodization was used to synthesize nanostructured copper oxide/copper (CuxO/Cu, x=1,2) electrodes for sensitive non-enzymatic glucose detection. The CuO/Cu electrode exhibited a high sensitivity of 2954.38 mu A mM(-1) cm(-2) to glucose and a linear range of 0.1 mM to 1.3 mM at a catalytic potential of 0.55 V. The electrode showed a fast response time of less than 3 s with the addition of 0.1 mM glucose. The nanostructure of the electrode, achieved through anodization in 1M KOH solution at -100 mV, contributed to the efficient glucose catalytic oxidation process and could be controlled by adjusting the potential and electrolyte concentration during anodization.

Summary: Photoresists play a crucial role in industrial fields like micro-electro mechanical systems, micromachining, and chip packaging. Traditional single-component photoresists require additional steps to render them conductive, making the process complex and limiting their applications. By doping graphene and silver nanowires into SU-8 photoresist, a conductive composite photoresist was successfully developed for micro-patterning and nonenzymatic sensing coatings.

Summary: Nanostructured graphene has been widely studied in recent years due to its tunable electronic properties for various fields. However, exposure of (3,1)-chiral graphene nanoribbons to oxidizing environments significantly oxidizes the ribbons and disrupts their electronic properties. Experiments show that even under gentle conditions, the ribbons are oxidized, providing insights into the reaction sites and defects caused by oxygen.

Summary: In this study, the electrocatalytic behavior of different substituted MnII salophen complexes for water oxidation was evaluated. The results showed that all three complexes were highly effective and stable catalysts for water oxidation. The nature of the substituent on the salophen ligand did not affect the stability of the complexes. Mn oxide nanostructures obtained by thermal decomposition also exhibited catalytic activity, albeit lower than the MnL1 complex.

Summary: In this study, an efficient room-temperature gas sensor was synthesized using a microwave-assisted hydrothermal method, with a hybrid nanostructure composed of biomass-derived graphene nanosheets and Ag2S. The hybrid nanostructure showed higher hydrogen sensing efficiency than pure Ag2S nanoparticles, with a maximum response of 45.5% for 150 ppm exposure of hydrogen gas at room temperature. The fast response time and high gas sensitivity of the hybrid sensor were attributed to the diverse attributes and synergetic effect between Ag2S and GNS hybrids.

Summary: In this study, expanded vertical graphene/diamond films with regular and ordered 0.7-nm layered channels were designed and synthesized to serve as an ideal model for understanding confined electrical double-layers (EDLs). Through various techniques such as in situ electrochemical Raman spectroscopy, electrochemical quartz crystal microbalance, and density functional theory calculations combined with three-dimensional reference interaction site method, a clear overall picture of confined EDLs at an atomic resolution was provided. The results show that the induced charges in electrode hosts have a high localization density, which is essential for the high energy storage efficiency of confined EDL capacitance. This research not only refines the mechanism of confined EDLs but also contributes to the understanding of nanoporous or layered materials in electrochemical energy storage.

Summary: This study investigates the effects of electronic effects at the interface between Co4N nanoparticles and nitrogen-doped carbon nanowalls/diamond on the activity of the reversible oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The study finds that the vacancy defect-induced Co-pyridinic N-C bond can optimize the electronic structure of Co 3d orbitals and balance the adsorption energies of intermediates along the reaction pathways. Accordingly, the synthesized Co4N@d-NCNWs/D composites exhibit excellent bifunctional oxygen catalytic activity.

Summary: This study introduces a polyanionic strategy by developing a hydrogel electrolyte with carboxyl groups, to improve the reversibility and performance of aqueous Zn-ion energy storage systems. The carboxyl groups in the hydrogel structure promote the transport of Zn2+ ions and expedite their desolvation, leading to enhanced deposition kinetics. These functional groups also suppress dendritic growth and side reactions, resulting in a smooth surface texture of the Zn anode. The electrolyte exhibits high Coulombic efficiency and exceptional cyclability, making it suitable for energy storage in flexible, intelligent electronics.
