Summary: Silicon has garnered attention for its high specific capacity and abundant reserves, but its volumetric changes during charging and discharging processes have hindered industrial utilization. This study introduces a novel hybrid anode material, Si@void/CNF, designed with a nodes-connected structure that provides both a conductive reticulation for silicon nanoparticles and addresses volume variation. By adjusting the mass ratio of silicon to PMMA, an optimal structure was achieved, demonstrating excellent electrochemical performance with high specific capacity and cycling stability. The electrospun structure of nodes-connected Si@void/CNF offers a promising method for fabricating advanced silicon-based anode materials.

Summary: In this study, three types of flexible 3D-interconnected carbon nanofibers were prepared and used as substrates for vertically grown ultrathin MoSe2 nanosheets. The resulting composites were employed as freestanding anodes for lithium-ion batteries, with the hollow multi-nanochannel structure of NHMCFs delivering the highest capacity after 400 cycles at 1 A g-1. The multi-nanochannel structure in NMCFs and NHMCFs helps alleviate volume changes during charge-discharge processes, while the uniform coating of MoSe2 nanosheets on NHMCFs increases mass loading and capacity.

Summary: This study analyzes the effect of adding water to the fuel stream during flame synthesis of carbon nanotubes (CNTs). The results show that water addition reduces flame height and axial extent of the growth region. However, the average growth region temperature and CNT morphology remain relatively unchanged. Additionally, water addition leads to a decrease in the thickness of the amorphous carbon layer in the growth region.

Summary: This study investigated the effect of neodymium oxide modification on the elastic, structural, and physical properties of magnesium borotellurite glasses. Increasing the concentration of Nd2O3 resulted in an increase in the density of the bulk samples from 3.97 g/cm3 to 4.10 g/cm3, while the molar volume showed the opposite trend. X-ray diffraction analysis confirmed the amorphous state of the glasses, and the elastic moduli exhibited a linear increase with the increment of Nd2O3. The elastic moduli calculated using the Makishima-Mackenzie and Rocherulle's models followed the same trend as the experimental values. The results indicated that the MBTNd-3 glass sample had the optimum properties for high-strength glass applications.

Summary: This study proposes a simple process for the room temperature fabrication of pseudocapacitor electrodes with an enhanced surface area and excellent faradaic redox reaction layer. A carbon layer containing fine Ni nanoparticles dispersed on a metallic electrode was successfully prepared through ion irradiation and local graphitization. The fabricated electrode showed a significantly increased stored charge ability compared to the bulk Ni foil. The results suggest that the carbon layer with Ni nanoparticles fabricated by ion irradiation has great potential for the development of supercapacitors.

Summary: The effects of variation of sputtering pressure on the structure and electrical properties of AlN HiPIMS deposited on Si substrate were investigated. The results showed that increasing the sputtering pressure led to a decrease in the thickness of the AlN thin film, while the lowest surface roughness was observed at a sputtering pressure of 5 mTorr. The electrical conductivity of AlN was directly proportional to the sputtering pressure and remained stable at different temperatures.
