Summary: Defect and facet engineering are two effective approaches to tune the surface reactivity of metal-oxide-based sensing materials. In this study, WO3 nanosheets with exposed (002) crystal facet and oxygen vacancies defective [D-WO3-(002)] were obtained through a simple hydrothermal-hydrogenation process. The D-WO3-(002)-based acetone sensor exhibited excellent gas sensitive performance, including low limit of detection (0.5 ppm), wide range of response (0.5-100 ppm, S = 2.8 & SIM; 45.6), high selectivity, fast response-recovery, and excellent repeatability. The outstanding gas-sensing performance is attributed to the synergistic effects of the dominant (002) facet and the defect of oxygen vacancy structure, which effectively improved the surface reactivity of monoclinic WO3 nanosheets. This work demonstrates tremendous potential application prospect for environmental monitoring of acetone and non-invasive diagnosis of diabetes.

Summary: In this study, the effects of polyethylene glycol (PEG) and L-3,4-dihydroxyphenylalanine (L-dopa) as structure directing agents on the growth of tungsten trioxide crystals by solvothermal method in acetonitrile solution were investigated. The presence of PEG and L-dopa led to a change in crystal growth mechanism, resulting in the transformation of crystal faces from stacked layers to smooth facets. The rate of crystal formation and growth was significantly increased in the presence of 5 w% PEG. The crystals grown in the presence of L-dopa were octahedral WO3·0.5H2O with smooth faces, while those grown in the presence of PEG were octahedral and rectangular microcrystals of WO3·H2O. The transparency and electro-optical properties of the crystal layers were improved in the presence of PEG.

Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

Summary: The WO3 and WO3:Pr3+ particles were synthesized successfully by co-precipitation method and their structures were characterized. The addition of Pr3+ induced structural and optical changes in the WO3 lattice, leading to increased crystallite size, distorted clusters, improved crystallinity, and modified optical gap. The particles showed nanocube morphology, and the photoluminescence was attributed to surface defects. The WO3:4% Pr3+ sample exhibited the highest photocatalytic efficiency for degrading Crystal Violet dye.

Summary: This research investigated the gas sensing performance of two different configurations of the h-WO3 polymorph produced by different processing routes, showing that the (100) textured sample had a higher response to acetone, while the (001) textured sample favored isoprene. The selectivity of the latter to isoprene is explained in terms of the dangling bonds present on the (001) facets.

Summary: In this study, a multilayer stack structure composed of absorption-dominated thin films and reflection-dominated thick film is proposed to achieve high shielding effectiveness and low reflection in high conductivity electromagnetic interference (EMI) material. Experimental results show that a three-ply stack of two thin films and a thick film can achieve high EMI shielding effectiveness and absorption using silver nanowires (AgNWs) as the material. The multilayer structure can regulate the shielding mechanism from reflection-dominated to absorption-dominated. This study provides a promising approach for developing high-efficient and absorption-dominated EMI shielding materials.
