Summary: This article reports the effect of Cobalt dopant on the thermoelectric properties of nanostructured Cadmium Oxide at high temperatures. The synthesized samples showed a highly crystalline structure and successful substitution of Cd2+ ions by Co2+ ions. The presence of Cobalt increased the charge carrier concentration and Hall mobility, while decreasing the electrical resistivity. The highest thermoelectric power factor was obtained for 6% Co-doped CdO at 950 K.

Summary: Highly crystallized PbS films synthesized via chemical bath are important for civilian applications. TEA solvent is more suitable for synthesizing highly crystallized PbS films compared to NH3 center dot H2O and TSC solvents. Increasing TEA concentration leads to larger crystallite size and a shift in optical absorption edge from red to blue.

Summary: In this study, LaS2 ultrafine nanostructures were successfully synthesized using anisotropic nanostructures of La(OH)(3), which have applications in display devices, optoelectronics, field emission, and thermoelectric devices due to their low work function and excellent chemical and physical properties. Anisotropic La(OH)(3) was synthesized by the micellar-assisted hydrothermal route and then reacted with elemental sulfur at ambient pressure to obtain stable LaS2 nanoparticles with a size of about 25 nm. The obtained lanthanum disulfide was used to make LaS2 ink and spin-coated onto a silicon substrate to fabricate a LaS2 film. The field emission study of the LaS2 film showed the lowest turn-on field (<3.9 V/mu m), a high field enhancement factor (beta = 14,594), and a high current density of 7.15 mu A/cm(2), which is about 10 times higher than previous reports.

Summary: 2M-WS2 is a metastable form of WS2, a superconducting transition metal dichalcogenide (TMD), consisting of layers of distorted WS6 octahedra. It is predicted to exhibit non-Abelian quantum states, making it attractive for topological computing. However, 2M-WS2 cannot be synthesized by traditional solid-state methods and requires a top-down approach involving deintercalation of K+ from K( x )WS(2). In this study, we discovered that the deintercalation of K from K x WS2 is spontaneous and an acid-based reaction environment is sufficient to convert it to 2M-WS2. By using less aggressive methods, we were able to produce high-quality 2M-WS2 crystals with higher superconducting volume fractions.

Summary: Pure and Co-doped CuS nanoparticles were prepared by precipitation method, with increasing Co content leading to decreased crystallite size. EDS spectra confirmed the inclusion of Co in the doped samples. The PL intensities of the doped samples were increased due to enhanced radiative recombination rate. Co doping improved electrochemical, NLO, magnetic, and antimicrobial characteristics. Chitosan-loaded 10 wt% Co-doped CuS NPs exhibited improved electrochemical behavior and enhanced antibacterial property.

Summary: Lanthanum doped cadmium oxide (CdO:La) nanoparticles with different La contents (0, 3, 5 and 7 wt%) were synthesized using the sol-gel method. The crystalline degree of CdO depended on the amount of La dopant, resulting in the formation of cauliflower shaped grains. EDS spectra confirmed the presence of La in the doped materials. Increasing La doping improved transparency, and the 5 wt% La-doped sample showed a high transparency of 90% with a maximum band gap of 2.51 eV. La doping also reduced resistivity, with the 5 wt% La-doped CdO sample exhibiting a minimum sheet resistance of 11.8 & OHM;/ and resistivity of 4.26 x 10-4 & OHM;-cm, along with a high figure of merit of 7.56 x 10-4 & OHM;-1. Additionally, the 5 wt% La-doped sample showed a high specific capacitance of 110 F/g, and improved third order nonlinear optical characteristics.

Summary: This study examines the third order nonlinear optical (NLO) and electrochemical properties of spray deposited lanthanum doped lead sulfide (PbS:La) thin films. It was found that La doping improves the crystallization, surface morphology, and band gap of the films, resulting in enhanced nonlinear optical absorption and a higher nonlinear refractive index. Additionally, the La-doped films exhibit increased specific capacitance and decreased charge transfer resistance in electrochemical studies.
