Herein, we report the novel nanostructural interfaces of self-assembled hierarchical ZnO nanotubes/graphene (ZNT/G) with three different growing times ZNTs on graphene substrates (namely, SH1, SH2, and SH3). Each sample was fabricated interdigitated electrodes to form hydrogen sensors, their sensing properties were comprehensively studied. The systematic investigation revealed that SH1 sensor exhibits an ultrahigh response even at a low detection level 10 ppm (14.3%) 100 (28.1%) compared...
Granular activated carbon (GAC) materials were prepared via simple gas activation of silkworm cocoons and coated on ZnO nanorods (ZNRs) by the facile hydrothermal method. The present combination GAC ZNRs shows a core-shell structure (where is surface ZNRs) exposed systematic material analysis. as-prepared samples then fabricated as dual-functional sensors and, most fascinatingly, as-fabricated exhibits better UV H2 sensing properties than those GAC. Thus, structure-based sensor fast...
Molybdenum diselenide (MoSe2) is a promising gas sensing material due to its large surface-to-volume ratio, narrow band gap, and excellent absorptions. However, MoSe2-based sensors possess inferior response recovery at room temperature. In this context, assembly of hybrid structures can be an effective technique stimulate the intrinsic structural electronic properties MoSe2 nanosheets (NSs). Herein, we report interfacial science engineering design unique p–n hetero nanostructure for first...
Due to environmental problems such as global warming and ozone depletion, it is essential detect harmful UV rays from sunlight commercialize a clean energy source (H<sub>2</sub>), both issues require reliable sensor.
Herein, the novel strategy of copper oxide (CuO) deposited oxygen-doped nitrogen incorporated nanodiamond (NOND)/Si pyramids (Pyr-Si) heterostructure is studied for high-performance nonenzymatic glucose sensor. The combined properties surface-modified NOND/Pyr-Si induced by different growth durations (5 to 20 min) CuO envisioned improve sensitivity and stability. For comparison, same methods parameters were on plane silicon wafers. systematic analysis reveals best sensing 15 min grown...
Future innovation of optoelectronic industrial applications for energy saving devices such as self-powered sensors and photodetectors have gained much research attention.
A discontinuous lanthanum (La<sup>3+</sup>)-coated ZnO nanorod-based multisensor was fabricated for the first time. The H<sub>2</sub> gas and UV sensing properties were studied simultaneously.
Herein, multiwalled carbon nanotubes (MWCNTs) were synthesized through a two-step chemical vapor deposition process via an ultra-nanocrystalline diamond (ND) as source for the first time, and no gaseous molecules used during CNT growth. A unique core–shell-like morphology was revealed from high-resolution transmission electron microscopy (HRTEM) microstructure in which is covered by nanodiamond grain boundaries. The NDCNT then fabricated with metal interdigitated electrode to form hydrogen...
Monitoring the hydrogen gas (H2) level is highly important in a wide range of applications. Oxide-carbon hybrids have emerged as promising material for fabrication sensors this purpose. Here, first time, graphitic carbon nitride (g-C3N4)-doped zinc oxide nanorods (ZNRs) been grown on silicon (Si) pyramid-shaped surfaces by facile hydrothermal reaction method. The systematic analyses revealed that g-C3N4 nanostructures (NS) consistently incorporated into ZNRs pyramidal (Py-Si) surface...

Herein, for the first time, a combination of detonation nanodiamond (DND)–tungsten disulfide (WS2) was devised and studied its selective H2-sensing properties at room temperature. DND–WS2 samples were prepared by sonication-assisted (van der Waals interaction) liquid-phase exfoliation process in low-boiling solvents with DND as surfactant. The further hydrothermally treated an autoclave under high pressure as-prepared separated two parts named BH (before hydrothermal) AH (after...
High performance UV/Visible photodetectors are successfully fabricated from ZnO/fibroin protein-carbon nanotube (ZFPCNT ) composites using a simple hydrothermal method. The as-fabricated ZnO nanorods (ZnO NRs) and ZFPCNT nanostructures were measured under different light illuminations. measurements showed the UV-light photoresponse of (55,555) to be approximately 26454 % higher than that as-prepared NRs (210). This photodetector can sense photons with energies considerably smaller (2.75 eV)...
A novel self-assembled hierarchical heterostructure is derived from cocoon-derived sericin biopolymer (CSP) biowaste with ZnO deposited on ultra-nanocrystalline diamond (UNCD) substrates using a scalable chemical deposition technique. Then, high-performance long-life UV photodetectors are fabricated this hybrid sericin, diamond, and (SDZ) nanostructure.

In this study, we report nitrogen-doped nanodiamond (ND)-integrated crushed graphene (Gr) nanoflakes on nickel hydroxide (Ni(OH)2, named NH) nanostructures for highly stable nonenzymatic glucose sensors.
