Summary: This study successfully synthesized high-quality single-walled carbon nanotubes (SWNTs) on layered double hydroxides (LDHs) containing Fe and FeCo using CO chemical vapor deposition (CVD). The effects of temperature and catalyst composition on the diameter and chirality distributions of SWNTs were investigated. It was found that subnanometer SWNTs were produced by both catalysts at low temperatures. The (6, 5) SWNTs were synthesized from LDHs containing bimetallic FeCo at 600 degrees C, and the chirality distribution was further narrowed by a two-phase extraction method.

Summary: Novel glass-ceramic composites with tunable optical bandgap were synthesized by mixing zinc silicate powder with multi-walled carbon nanotubes at different mass fractions and sintering under argon atmosphere. The addition of MWCNTs enhanced the crystallinity of ZS and resulted in a shift in the emission wavelength of Zn2SiO4. No chemical interaction between ZS and MWCNTs was observed, indicating that MWCNTs mainly influenced the performance of the composites by enhancing crystallization.

Summary: Nanomaterials, especially carbon-based nanomaterials, have been widely used in various biomedical applications. In this study, a process intensification approach for attaching immunoglobulin G (IgG) to multi-walled carbon nanotubes (MWCNTs) was proposed and evaluated. The effect of different parameters on the IgG attachment yield was investigated, and it was found that dilution of rabbit serum increased the IgG yield while decreasing other protein attachment. The orientation of IgG on the MWCNTs surface was determined to be end-on, which suggests that this attachment strategy could be effective for antigen recognition and biomedical applications.

Summary: Poly(triarylamine) (PTAA)-wrapped single-walled carbon nanotubes (SWCNTs) served as both an efficient hole-transporting layer and electrode in perovskite solar cells (PSCs). The dopant-free PTAA used in this dual-role SWCNTs electrode resulted in a well-matched energy level, increased hole-transporting mobility, and hydrophobicity, leading to improved efficiency and stability compared to reference standards using LiTFSI-doped Spiro-OMeTAD. This dopant-free PTAA-applied SWCNTs electrode not only enables efficient utilization of SWCNTs electrodes in PSCs, but also reveals the mechanism of interaction between the hole-transporting layer and SWCNTs.

Summary: The electrochemical behavior of gallic acid on a single-walled carbon nanotubes-modified electrode was investigated using cyclic voltammetry and chronoamperometry. Diffusion phenomena were found to be responsible for the overall current signal, and these phenomena were divided into four processes occurring in thin-layer or solution. The effects of scan rate, gallic acid concentration, and layer thickness on the voltammetric signal were discussed based on the diffusion processes in the thin-layer.

Summary: Bacterial cells have various glycopolymers on their surface, and targeting the assembly of peptidoglycan (PG) has proven effective in antibiotic development. Biosynthesis of other surface glycopolymers is also considered potential targets for controlling bacterial infections. The common lipid carrier used for PG assembly is closely related to the biosynthesis of most surface glycopolymers. This review provides an overview of PG assembly, antibiotics targeting this pathway, and the implications of using a common lipid carrier in antibiotic development.

Summary: Magnetic Nd2Fe14B nanoparticles were synthesized via a calciothermic reduction process, achieving nanoscale products. Selective removal of residual calcium by-products was necessary to obtain high-purity, high-performance magnetic nanoparticles. A novel rinsing solution, NH4NO3/methanol, was proposed to remove calcium by-products without deteriorating the magnetic properties. The magnetic properties were enhanced, with maintained intrinsic coercivity and increased saturation magnetization, after rinsing with NH4NO3 solution.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
