This study fabricates and characterizes ultraviolet (UV) photosensors with ZnO nanorods (NRs). The NR arrays were selectively grown in the gap between interdigitated (IDT) electrodes of devices using hydrothermal solution processes a lithography-based technique. Compared conventional photosensor without NRs, proposed UV have much higher photoresponse region. Additionally, photoconductive gain an increased as illumination time increased; it varied at 34.45-5.32 x 10(2) under by 18.28 mW/cm(2)...
Metal-semiconductor-metal (MSM) ultraviolet (UV) photodetectors with ZnO nanorods (NRs) have been fabricated and characterized in this investigation. The NR arrays were selectively grown on the gap of interdigitated electrodes by chemical solution method through a photolithography process. Compared to traditional MSM photodetector no NRs, UV showed much higher photoresponsity. As result, it can be attributed high surface-to-volume ratio NRs such photoresponse could strongly depend oxygen...
Zr-based Laves phase alloys, especially ZrMn<sub>2</sub>, have been widely studied because of their good hydrogen storage properties.
An ultraviolet-enhanced (UV-enhanced) nitric oxide (NO) sensor based on silver-doped zinc (ZnO) nanoflowers is developed using a low-cost hydrothermal method. The results indicate that silver (Ag) ions were doped into the ZnO nanostructure successfully, thus changing morphology. In high-resolution transmission electron microscopy images, we also found some Ag separated out onto surface of and Ag-doped nanoparticles improved sensing property. NO property increased from 73.91 to 89.04% through...
Magnesium hydride (MgH2) has been considered as a promising hydrogen storage material for buildings that are powered by energy, but its practical application is hampered poor kinetics and unstable thermodynamics.

This study describes the fabrication of ultraviolet photodetectors with laterally aligned ZnO nanobridge arrays. These arrays grow upward in face-to-face direction, thereby forming biaxial compressive stress where nanobridges intersect. Compared conventional thin-film photodetectors, devices markedly enhance photosensitivity and blue shift (30 nm) spectral response. phenomena are caused by surface effects strain-induced polarization effects, leading to band structure change. Nanobridge a...
