Summary: Cu and Y co-doped TiO2 nanoparticles were prepared using an acid-catalytic sol-gel process, resulting in a single anatase phase with reduced crystallite size. SEM observations showed uniform nanospheres being synthesized under the proposed conditions. XPS results demonstrated the presence of Cu+ and Y3+ ions. The photoactivity of the co-doped TiO2 was improved due to effective separation of electron-hole pairs, increased formation of active radicals, and increased surface area.

Summary: In this study, gadolinium-doped nickel ferrite thin films were synthesized using a sol-gel method, and the effects of Gd doping on the structural, optical, and magnetic properties were investigated. The results showed that with increasing Gd concentration, the lattice parameter increased, crystalline size decreased, optical band gap value increased, and better magnetic properties were observed at an appropriate Gd-doping concentration. Additionally, saturation magnetization was found to increase significantly and then sharply decrease with increasing Gd content, attributed to Gd-doping, exchange interaction, and redistribution of cations.

Summary: In this research, pristine nickel oxide (NiO) and Mn-doped NiO nanoparticles (NPs) were synthesized using the chemical precipitation method. Characterization techniques such as X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-Visible diffuse reflectance spectroscopy, scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX), transmission electron microscopy/selected area electron diffraction (TEM/SAED), vibrating sample magnetometer, and cyclic voltammetry were used to analyze the properties of the NPs. The results showed that the NPs exhibited face-centered cubic structures with decreasing crystallite sizes. The presence of Mn ions led to a transition from weak ferromagnetism to superparamagnetism. Pristine NiO samples exhibited the highest capacitance of 555 F/g at a scan rate of 10 mV/s. These NiO and Mn-doped NiO NPs have potential applications in data storage and supercapacitors.

Summary: In this study, BaYxFe12-xO19 was synthesized using citrate precursor technology with x values of 0.0, 0.1, and 0.2. Fourier Transform Infrared and UV spectroscopy, as well as Powder X-ray Diffraction, were used to determine the structure and confirm the phase formation. The magnetization versus magnetic field data showed an increase in magnetization value from 8.77 emu/g to 26.22 emu/g with the increase in doping concentration from x = 0.0-0.20. The antimicrobial activity of Y-doped BaFe12O19 against Staphylococcus aureus and Escherichia coli was observed at all concentrations, with MIC values ranging from 0.55 to 0.80 mg/ml.

Summary: Bismuth ferrite-based oxide nanostructures were chemically synthesized and employed as photoelectrodes for water splitting reactions and remediation of organic pollutants. The incorporation of gold (Au) nanoparticles induced plasmonic effects, impacting the physicochemical properties and application performance of the materials. XRD, absorbance, and TEM analyses confirmed the interaction between Au and BFO nanoparticles. Plasmonic effects were observed in the absorbance spectra, indicating significant changes in the optical properties upon Au decoration. Photoluminescence spectra revealed the influence of BFO and Au nanoparticles on defect states and charge transfer. Comparative analysis demonstrated enhanced photo-catalytic and photoelectrochemical performance of Au-decorated BFO nanostructures. Time-dependent photocurrent density studies proved the stability and improved charge transfer efficiency of Au-decorated photoelectrodes. The nanocomposite exhibited efficient degradation of organic pollutants and enhanced hydrogen production from water splitting under sunlight illumination.

Summary: This article reports the enhancement of specific capacitance in Mg-doped tin oxide nanoparticles synthesized through a simple and low-cost solvothermal method. The specific capacitance of undoped samples was found to be 523 and 55 F g(-1) through cyclic voltammetry and galvanostatic charge/discharge studies, respectively. However, with Mg doping, the specific capacitance increased to 981 and 134 F g(-1). The enhancement in capacitive performance of Mg-doped nanoparticles was attributed to the increased ion diffusion, as observed through electrochemical impedance spectroscopy analysis.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.
