Summary: Hf1-x(In0.5Nb0.5)(x)O-2 (x = 0, 0.005, 0.05, and 0.1) ceramics doped with (In+Nb) were prepared by a solid-state reaction method. Dielectric measurements showed that environmental moisture significantly influenced the dielectric properties, with the best humidity response observed in the sample with x = 0.005. Nanosized particles of Hf-0.995(In0.5Nb0.5)(0.005)O-2 were fabricated by a hydrothermal method and their humidity sensing properties were studied. The material exhibited a large impedance change of nearly four orders of magnitude over a relative humidity range of 11-94%, which was attributed to the defects created by doping and improved adsorption capacity for water molecules.

Summary: In this study, lanthanum ferrite samples doped with different concentrations of strontium were prepared using electrospinning. The sample with a surface atomic ratio of approximately 0.2 showed a 6 x 104 times change in resistance at 90% relative humidity, and a response of 6.76 at 4% relative humidity. Suitable strontium doping decreased the adsorption energy and increased the charge transfer during water molecule adsorption on the surface of lanthanum ferrite. This study offers a new perspective for enhancing humidity sensor sensitivity through surface regulation.

Summary: In this study, vanadium carbide (V(2C)Tx) MXene was successfully synthesized and treated with an ammonia solution under different pressures using a hydrothermal process. The results show that the morphology of V(2)CTx MXene changed from uneven multilayered micrometre-size sheets to uniform few-layered nanometer-size sheets as the pressure increased. The optical and electronic properties were influenced by nitrogen-related defects, quantum confinement, and induced lattice strain due to the post-ammonia treatment.

Summary: Two Schiff base complexes, [CuL2] (Cu-Sal) and [CoL3] (Co-Sal), were synthesized and characterized. Crystal structure analysis showed a square planar geometry around Cu(ii) and various intermolecular non-covalent interactions in Cu-Sal. Both complexes were used as sensitizers in TiO2 based dye sensitized solar cells (DSSCs), and Co-Sal exhibited better photovoltaic performance than Cu-Sal due to improved light absorption and dye loading.
