Summary: The development of advanced materials with enhanced and unusual properties has been promoted by the increasing knowledge in nanoscience and materials technology. This study presents the results of investigations on composite semiconducting materials. The composites, prepared from different nitrogen precursors and thin films of TiO2 nanotubes, were characterized to understand the relation between photo-behavior and composition. The studied g-C3N4/TiNT heterojunctions showed enhanced photo-electrochemical properties and could be potentially used in H-2 production, solar-light-driven water splitting, and CO2 reduction applications.

Summary: In this study, Sm3+, Mo6+ dual-doped LiMn2O4 positive materials were fabricated using a solid phase strategy. The electrochemical test results showed that the material exhibited high discharge capacity and capacity retention at high rates, as well as lower manganese dissolution in organic electrolyte. This suggests that the co-doping of Sm3+ and Mo6+ can effectively enhance the structural stability and electrochemical properties of spinel Mn-based positive electrodes.

Summary: Graphitic carbon nitride (GCN)-based nanostructures have shown promising applications in electrochemical detection of hazardous contaminants. However, a comprehensive analysis of recent research developments and the use of GCN-based sensing materials in electrochemical detection has not been fully explored. In this review, the synthesis, properties, and applications of GCN composites for the detection of hazardous contaminants were systematically analyzed and reviewed, providing insights into the immobilization methods, modification strategies, advantages, and disadvantages. The potential of GCN-based sensing materials for on-site electrochemical detection of hazardous contaminants and the advantages of on-site electrochemical sensing strategies and portable devices were emphasized.

Summary: A group of rare-earth metals functionalized mesoporous Ni-M/Al2O3 (M = Tb, Dy, Nd) composite oxides were prepared and applied in the CO2 methanation process. The addition of terbium (Tb) improved the catalytic performance, particularly at low temperatures. The superior catalytic performance of 25Ni-5Tb-Al2O3 could be attributed to the appropriate fabrication method and the promotion effect of terbium.

Summary: Recent years have witnessed the growing prominence of implants in the health field and the revival of damaged organs. Planktonic bacteria on the surface of implants pose risks of infections and biofilm formation, which can lead to severe pain and even death. The risk of infection after orthopedic surgery remains high. Biofilm infections destroy adjacent tissues and hinder antibiotic delivery, making treatment difficult. Topical drug delivery, using antibiotic-loaded implants, metallic and metal oxide nanoparticles, polymers, and antimicrobial peptides, offers promising solutions to reduce these risks.

Summary: Thulium vanadate (TmVO4) nanorods were synthesized using Schiff-base ligands through a sonochemical method, and they exhibited promising photocatalytic activity. The crystal structure and morphology of TmVO4 were optimized by varying the Schiff-base ligands, H2Salen molar ratio, sonication time and power, and calcination time. The specific surface area was determined to be 24.91 m2/g, and the bandgap was found to be 2.3 eV, indicating its potential for visible light photocatalytic applications. The highest efficiency of 97.7% was achieved under visible light when 45 mg TmVO4 nanocatalysts were present in 10 ppm Eriochorome Black T solution at pH = 10.

Summary: In this study, a green chemistry method was used to synthesize ErFeO3/Fe3O4/rGO nanocomposite using sucrose as an active capping and reducing agent. Characterization techniques such as TEM, SEM, XRD, BET-BJH, VSM, and HRTEM were employed to analyze the nanocomposite. The results indicated that the nanocomposite exhibited pure particles with a size range of 37 +/- 2 nm, as validated by TEM examination. Furthermore, the synthesized nanocomposite showed significant anti-proliferative effects on T98 and SH-SY5Y cancer cell lines, suggesting its potential for inducing cancer cell death in vitro. However, further research is required to elucidate the underlying mechanisms.

Summary: This study presents a gel polymer electrolyte (GPE) interlayer to stabilize the Li|LAGP interface and address the challenges caused by side reactions and poor thermal stability. The GPE, composed of a solvate ionic liquid and a hyperbranched polyanionic copolymer, ensures excellent compatibility and protection between LAGP and Li metal anode. Additionally, the introduction of a solvate ionic liquid with non-inflammability effectively avoids thermal runaway between lithium metal and LAGP at high temperatures.

Summary: The morphologies of active materials have an impact on hydrogen storage performance. Changing the synthesis conditions can modify the size and morphology of active materials. Nanostructured Ce2Y2O7 with five different morphologies was synthesized using a sol-gel process assisted by trimessic acid. Charge-discharge chronopotentiometry tests were conducted under the same conditions to compare the effects of Ce2Y2O7 nanostructures on hydrogen storage capacity in KOH electrolyte at a current of 1 mA. The results show that the highest capacity is observed in very thin nanoribbons (643 mAhg(-1)), while the lowest capacity is found in agglomerated ribbons assembled with particles (276 mAhg(-1)).

Summary: In various industries, it is crucial to understand the relationship between transfer properties like viscosity and thermal conductivity coefficients for design and engineering purposes when processing non-Newtonian fluids, especially viscoelastic fluids. However, most studies on nanofluids have been limited to inadequately considering only three components of viscoelastic fluids. In this research, multiwalled carbon nanotubes were chemically modified to obtain nanoparticles, which were then used to prepare viscoelastic-based nanoliquids (VNLs). The stability, thermal conductivity, and viscosity of the VNLs were examined. The findings provided insights into the behavior and properties of these complex fluids.
