Summary: The study focused on the preparation of Ag-modified VO2 nanorods using a two-step method to improve NO2 sensing performance at room temperature. The results showed that nanorods annealed at 450 degrees Celsius had the highest sensitivity, reaching a response value of up to 2.54-5 ppm NO2, while the response value decreased as humidity increased. The good sensing performance was attributed to the catalytic effect of Ag nanoparticles and the changing of the energy band gap.

Summary: This report focuses on the deposition of nanocrystalline aluminium doped ZnO (Al doped ZnO: AZO) samples on seeded glass substrates using a cost-effective reflux method. The doping concentration of 'Al' ions ranged from 1 to 3 vol%. The study found that the deposited AZO samples exhibited a wurtzite hexagonal crystal structure and the formation of nanorods for undoped ZnO, with a reduction in diameter and the formation of fine tips for AZO samples. The photoluminescence study confirmed the presence of oxygen vacancies and defects in the AZO samples. Furthermore, the AZO samples demonstrated excellent gas sensing performance towards NO2 gas at a temperature of 175 degrees C, with a gas sensitivity of 85% for 5 ppm NO2 gas. This work shows promise for practical applications in the gas sensor technology field, particularly for low detection limits at low operating temperatures.

Summary: It is a great challenge to assemble a heterojunction-based composite nanomaterial to achieve higher response and superior selectivity towards NO2 under room temperature conditions. In this work, the MXene@Polypyrrole heterojunction was synthesized using a facile in-suit chemical polymerization approach. The response value of the 0.5MXP sensor towards 50 ppm NO2 was significantly higher than that of the pristine MXene based sensor, showing a greater response (6.5-fold). The Schottky barriers formed between MXene and PPy contact surface led to the ideal selectivity and a lower limit of detection.

Summary: Porous TiO2 nanoparticle-embedded In2O3 nanofibers were synthesized for fabricating room temperature nitrogen dioxide gas sensors. The TiO2/In2O3 nanofibers exhibited higher response, shorter response and recovery times, better reproducibility, and improved selectivity to NO2 compared to pure In2O3 nanofibers. The enhanced NO2 sensing performance of the composite can be attributed to the formation of the TiO2/In2O3 n-n heterojunction, porous structure of the nanofibers, enhanced light absorption, and large number of O vacancies.

Summary: This study investigates the defects, defect clusters, and band tailing characteristics in Cu2ZnSn(S,Se)(4) thin films and their impact on device performance. The concentration of Zn-Cu and Sn-Cu defects, as well as B-type and C-type defect clusters, plays a critical role in determining the device parameters. The trend in short circuit current densities is independent of defects and defect cluster concentrations. The existence of minor secondary phases on the kesterite surface can affect the band tailing characteristics.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
