Summary: TiO2/KNbO3 nanocomposite was prepared by a two-step hydrothermal method, and impedance-type sensors based on TiO2/KNbO3, TiO2, and KNbO3 were fabricated. The TiO2/KNbO3-based sensor exhibited a large impedance change over 5 orders of magnitude, which was 1-2 orders of magnitude larger than that of TiO2- and KNbO3-based sensors. The improved humidity sensing performance of the TiO2/KNbO3 nanocomposite was attributed to the heterojunction at the TiO2/KNbO3 interface and the Grotthuss mechanism. This study highlights the significance of the two-step hydrothermal method in fabricating high-purity nanocomposites with excellent humidity sensing performance.

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: This study reports three novel n-type conjugated polymer semiconductors incorporating carborane in the polymer backbone and demonstrates their applicability in optoelectronic devices. The optoelectronic properties of para-, meta-, and ortho-carborane isomers were compared and similar energetic characteristics were found between the different polymers. The carborane unit in the polymer acts as a conjugation breaker, confining electron delocalisation to the conjugated moieties. Fabrication of all-polymer organic photovoltaic (OPV) devices and thin-film transistors (TFTs) showed differences in device performance, with the meta-carborane based polymer exhibiting superior performance in both OPV and TFT devices.

Summary: We report the synthesis and characterization of four novel n-type polymer semiconductors containing a 2-(1,3-dithiol-2-ylidene)malonitrile (DTYM) group as an acceptor and a 2,1,3-benzothiadiazole (BT) unit. The introduction of the DTYM group leads to backbone twisting and blue-shifted absorption, but increases the dipole moment and electron affinity. All polymers exhibit n-type semiconducting character in organic field-effect transistors (OFETs), with the fluorinated bithiophene donor demonstrating the best performance. This work highlights the influence of the DTYM group on polymer semiconductors and its potential as a functional group to enhance electron affinity.

Summary: The synthesis of two novel n-type molecular organic semiconductors based on a fluorinated indacenodithiophene core in combination with an electron withdrawing N-cyanoimine group is reported. The N-cyanoimine is confirmed to be a strongly electron accepting group, which in combination with the core fluorination resulted in high electron affinities for both materials. Significant differences in electron transfer integrals for the two regioisomers were observed, relating to differences in relative molecular displacement along the pi-stacking direction.
