Summary: In this study, graphene supported FeNi bimetallic nanoparticles (FeNi@GR) were prepared by alloying and carrier supported dispersion for efficient removal of azo dyes from water. The FeNi@GR not only effectively solves the problem of excessive agglomeration and oxidation of nZVI, but also enhances reactivity due to the synergistic effect of bimetallic coordination formation and the excellent electron transfer ability of graphene. The optimal FeNi@GR with 10% GR content showed a high removal rate of Congo red (CR) within 150 minutes at pH 7.0, and had excellent magnetic response performance with a saturation magnetization of 68.15 emu g(-1). This work provides a promising approach for water pollution remediation by stabilizing nZVI using FeNi@GR.

Summary: In this study, multishelled hollow structures (HoMSs) with different shell numbers, thicknesses, pore sizes, surface areas, and void sizes were successfully synthesized using carbon microspheres as a hard template and two different strategies: two-step strategy (TsS) and one-step strategy (OsS). The ZnO@TiO2 HoMSSs synthesized by OsS (triple shelled) exhibited excellent potassium storage capacity, rate capability, reversibility, and cyclic life in aqueous alkaline batteries, thanks to the thinner shell, larger pore size, high surface area, and bigger voids that provided a distinctive buffering zone for charge-discharge and improved the structural stability and cycling stability during the OH- intercalation/de-intercalation process.

Summary: Designing high-performance catalysts for electrocatalytic hydrogen production remains a significant challenge. Small-size bimetallic alloy nanoparticles have garnered considerable attention in the field of electrocatalysis due to their large exposure of effective active sites and optimal geometric/electronic effects. In this study, ultra-small bimetallic PtM (M=Ni, Co) alloy nanoparticles (approximately 1.7 nm) were synthesized on carbon supports through laser irradiation in liquids. This unique method leverages the effective absorption of pulse laser energy by carbon supports to generate high temperatures, enabling the reduction of metallic ions precursors by ethanol molecules and the subsequent formation of alloy nanoparticles. The resulting bimetallic PtNi alloy nanoparticles exhibited significantly improved catalytic performance in the hydrogen evolution reaction (HER).

Summary: In this study, Janus membranes were used for the continuous synthesis of calcium carbonate through reactive crystallization. The Janus membrane facilitated rapid and directional transfer of CO32- ions through nanoscale hydrophilic channels, while generating confined ion adsorption and gating effect at the hydrophobic side. The method enabled the efficient production of hollow CaCO3 microcomposites in aqueous solution without the need for organic solvents or polymer additives, showing great potential for material engineering applications.

Summary: In this study, a suitable adsorbent of biodegradable hydroxyethylcellulose (HEC) with graphene oxide (GO) and Fe/Zn bimetallic nanoparticles was prepared. The factors affecting the adsorption process were evaluated, and the adsorbents showed high adsorption capacity with removal percentages of 85% and 95% for HEC-GO and HEC-GO/Fe-Zn, respectively. The adsorption data fitted well with the Langmuir model, and the kinetic data followed the pseudo-second-order model. The thermodynamic parameters indicated that the adsorption process was spontaneous and exothermic. Therefore, the nano-biocomposite can be used as an effective adsorbent for water pollutant removal.

Summary: Colloidal nanoalloys consisting of gold and silver have been studied for their combined advantageous properties. This research focuses on the electrical properties of these nanoalloys and demonstrates that the conductivity and relative permittivity increase linearly with an increase in gold molar fraction. This suggests that the electrical properties of colloidal nanoalloys can be easily tuned by adjusting their composition.

Summary: This study investigates the effect of adding nitrate on the laser-based photochemical synthesis of gold nanoparticles. The results show that nitrate enhances both the nucleation and growth rates, improving the size distribution of the gold nanoparticles. It is also found that the addition of an appropriate amount of nitrate can tune the average size of the nanoparticles, while excessive nitrate leads to particle connection.

Summary: We successfully demonstrate the growth of gallium phosphide (GaP) segments within indium phosphide (InP) nanowires, forming GaP/InP heterostructure nanowires. The GaP segments show visible wavelength photoluminescence (PL) during growth, while the InP nanowires emit infrared light. PL mapping and polarization analysis reveal that the emission mainly comes from the GaP segments. The experimentally obtained band gap values are verified with band structure calculations. This study contributes to the tuning of emission and optical properties of GaP/InP nanowires for future applications in information and communication technology.
