l-Glutamate is one of the most important neurotransmitters in the mammalian central nervous system, playing a vital role in many physiological processes and implicated in several neurological disorders, for which monitoring of dynamic levels of extracellular glutamate in the living brain tissues may contribute to medical understanding and treatments. Electrochemical sensing of glutamate has bee...

3D Shape-Morphing Display In article 2214766, Jae-Woong Jeong, Jiheong Kang, and co-workers, report a novel shape-morphing display capable of transforming its shape to create intricate structures from 2D planar form, providing realistic visual information enhanced user experience. By using low melting point alloy-graphene nanoplatelet-elastomer composite, the SMD can electrothermally achieve di...

Abstract Nanoparticles such as graphene have been added to various polymer matrices enhance the mechanical, thermal, and electrical properties of materials that require complex designs on a microscopic scale. Micro-machining is used process these nanocomposite achieve high surface quality dimensional accuracy while maintaining productivity. In this study, systematic micro-milling experiment was...

Abstract The traditional freeze-casting route for processing graphene-based aerogels is generally restricted to aqueously dispersed flakes of graphene oxide (GO) and post-processing reduction treatments, which brings restrictions the electrical properties. In this work, we report a versatile aqueous that uses ability GO todisperse nanoplatelets (GNP) produce rGO-GNP lamellar via unidirectional ...

This study aims to investigate the influence of graphene nanoplatelet (GNP) concentration on electrochemical and tribological properties GNP-poly(methyl methacrylate) (PMMA) composite coatings. GNP-PMMA coatings were prepared with varying GNP concentrations (0.5, 1.0, 3.0, 5.0 wt %) using drop-casting method onto AA6061 aluminum alloy substrates. Results showed that addition 1.0 % increased ten...

In this paper, we broaden our previous work, which investigated the influence of graphene nanoplatelets (GNPs) size on microstructure and hardness composite coatings, to determine effect GNP wear-resistance anti-corrosion property GNP-reinforced nickel coating (Ni/GNPs). The experimental results indicated that small material could enhance wear resistance for with rate 13.2 × 10–4 mm3/Nm, depth ...
