Summary: In this study, oxygen-containing functional groups were grafted onto the surface of carbon nanotubes (CNTs) to improve their dispersibility in an electrolyte. The characterization results showed that the functionalized CNTs had better dispersibility in composites compared to unfunctionalized CNTs.

Summary: This study investigated the influence of EDTA content on the synthesis of nickel oxide nanocatalysts and the growth behavior of carbon nanotubes using these catalysts. It was found that increasing the EDTA content led to a decrease in the proportion of Ni metal in the catalyst particles, resulting in the formation of pure NiO. The smallest crystallite size was observed when the ratio of Ni ions to EDTA was 1:1. The use of EDTA resulted in porous NiO agglomerates, and the fuel ratio affected the particle growth behavior. Increasing the F/O ratio led to excessive growth of catalyst particles, inhibiting further CNT growth. Raman spectroscopy analysis indicated the highest CNT crystallinity near an F/O ratio of 1:1.

Summary: This study investigates the electrodeposition of a three-dimensional nanocone-shaped surface structure on SUS304 stainless steel substrates. Different electrodeposition parameters are used to generate nanocone-shaped Ni coatings. A detailed description of the coating microstructure and composition is proposed for understanding the development of Ni nanocones during electrodeposition. Wetting tests compare the superhydrophobicity of the Ni nanocone coating, while wear tests verify the mechanical stability. The best performance in terms of superhydrophobicity and mechanical properties is achieved after 25 minutes of electrodeposition, where the newly formed Ni nanocones provide an additional air cushion to support surface water droplets and enhance wear resistance. The superhydrophobic Ni coating also exhibits good anti-icing properties. Water droplets freeze starting from the contact points between the water and the sample surface, and surface damage reduces the anti-icing properties of superhydrophobic samples.

Summary: Proton exchange membrane fuel cells (PEMFCs) are an important alternative to fossil fuels and batteries for electric vehicles. The high cost of PEMFCs is a barrier to commercialization, mainly due to the cost of catalyst materials. This study demonstrates a single-step synthesis of Pt-Ni and Pt-Ni-Mo(O) nanoparticles (NPs) using pulse electrodeposition onto a PEMFC's gas diffusion layer. The Pt-Ni and Pt-Ni-Mo(O) catalysts exhibit extremely high mass activities at the oxygen reduction reaction (ORR) with low Pt loadings. The ternary Pt-Ni-Mo(O) NPs show more amorphous characteristics compared to the binary Pt-Ni particles but still exhibit homogeneous behavior on a microscopic scale.

Summary: This research reports the discovery of super-semiconductors, which have resistivity 3-10 orders of magnitude lower than conventional semiconductors at room temperature. The transition from a metal state to a super-semiconducting state is observed, accompanied by an increase in hole carrier density and the mobility increase in electrons. This behavior is attributed to the generation of hot electrons and holes induced by metal plasmon resonance in nanostructured bimetallic arrays.
