Summary: Six samples of nano X-type hexagonal ferrites were synthesized by sol-gel technique, with X-ray diffraction patterns revealing pure phase at lower doping concentrations and a second phase at higher concentrations. The incorporation of Dy-Co ions enhanced the magnetic properties, suggesting potential applications in permanent magnets and perpendicular recording media. The study on dielectric parameters indicated that Dy-Co doping increased the dielectric constant and ac conductivity.

Summary: Crystalline and single-phase Y1-xScxFeO3 (x = 0, 0.5 & 1) nanoparticles were synthesized by sol-gel method. The nanocrystals had sizes ranging from 30 to 39 nm as determined by X-Ray Diffractometry (XRD). The morphology and surface characteristics of the samples were analyzed using Field Emission Scanning Electron Microscopy (FE-SEM) and energy dispersive spectroscopy (EDS). The magnetic properties of the samples exhibited antiferromagnetic and paramagnetic behaviors, while the electrical properties showed polarization-electric loops, dielectric constant changes, and dielectric loss through frequency and temperature. The band gap energy of YFeO3 and ScFeO3 was calculated to be 2.97 and 3.07 eV, respectively, using diffuse reflectance spectroscopy analysis.

Summary: Ba-doped TiO2 thin films were fabricated using the sol-gel dip-coated method. X-ray diffraction confirmed the formation of the anatase phase. With the increase of Ba doping, the size of the crystallite decreased. The bandgap of pure TiO2 and Ba-doped TiO2 thin films was in the range of 3.15-2.94 eV, which is beneficial for enhancing solar cell efficiency and water treatment. Ba-doped TiO2 thin films exhibited low dielectric constant suitable for high-frequency devices and showed ferromagnetism. The antibacterial activity of Ba-doped TiO2 was higher than that of pure TiO2, making it suitable for application in nanomedicine.

Summary: This study reports on the influence of terbium-doped nickel ferrite particles on the dielectric and magnetic properties of polymeric nanocomposites. The findings show that adding a certain filler content (x = 0.3) significantly improves the permittivity of the polyvinylidene fluoride matrix. High filler loading decreases the blocking temperature and promotes hard ferrimagnetic characteristics. The low-temperature regions exhibit higher saturation magnetization, retentivity, coercivity, and wider hysteresis loop area. The lightweight Tb-NFO-PVDF nanocomposite film offers superior advantages for electromagnetic shielding applications.

Summary: Gadolinium-doped manganese nano ferrites were synthesized using a sol-gel method for microwave absorbers and storage devices. XRD analysis showed a well crystalline cubic phase with smaller crystallite size in Gd-doped nanoferrites. The morphology was spherical with less agglomeration, and the bandgap was influenced by the dopant-driven synergistic effect. The magnetic hysteresis curves demonstrated a soft ferromagnetic nature with increasing coercivity and decreasing saturation. Gd co-doping altered the resistance of grain and grain boundaries, and better dielectric characteristics were observed with increasing Gd3+ concentration at higher AC frequencies (voltages). The lowest dielectric loss of 1.8542 and the highest dielectric constant of about 1574426.14 were observed for manganese nano ferrites influenced by Gd3+ ion.

Photoluminance measurements showed violet emissions for all samples, with the 3% doped sample exhibiting the lowest intensity, indicating its potential for applications in photocatalysis and lithium-ion batteries. Additionally, 3% aluminium doping was found to be the optimum concentration for tin oxide samples in photocatalytic applications.

Summary: The photodegradation of DOX can be effectively achieved by the synergy of adsorption and photocatalysis using graphene oxide-cerium oxide (GO-CeO2) nanocomposites. The synthesized GO-CeO2 nanocomposites showed high crystallinity, lower bandgap energy, and narrow particle size distribution. The removal of DOX was influenced by the pH of the solution, with neutral and alkaline conditions supporting the degradation process. The GO-CeO2 nanocomposites exhibited enhanced photocatalytic activity due to their lower bandgap energy and interfacial charge transfer. Moreover, the presence of co-existing ions and organic dyes also affected the removal efficiency of DOX.

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.
