Uniform CdS/ZnO core/shell nanowires are hydrothermally synthesized using a two-step process and assembled into photodetector NO2 optoelectronic sensor for the first time. The corresponding exhibits fast, reversible, stable response with rise time of ∼26 ms, decay ∼2.1 ms stability over 5 months. remarkable photosensitivity fast photoresponse attributed to formation heterojunction structure between CdS ZnO, which greatly inhibits recombination photoinduced electrons holes. also show an...
Low-dimensional all-inorganic metal halide perovskites have been demonstrated as excellent building blocks for high-performance optoelectronic devices. Although many progresses achieved in low-dimensional perovskites, the substitution of toxic Pb is urgent further applications. Here, we present growth lead-free CsSnX3 (X = Cl, Br, and I) perovskite nanowire (NW) arrays on a mica substrate by solid-source chemical vapor deposition method. All NW epitaxially grow to form equilateral triangles....

The resulting nanoflower-based sensor is confirmed to be the most sensitive ppb-level chemiresistor NO2 date. with strong gas-adsorbing and high eletron-donating capability towards molecules decisively determine sensitivity. As service our authors readers, this journal provides supporting information supplied authors. Such materials peer reviewed may re-organized for online...
Optoelectronic sensing of gas phase hazardous chemicals is a newly explored field, which shows great advantages towards low concentration when compared to normal in the dark. Here, based on recent progress nanostructured vapor explosive sensors operated dark conditions, attractiveness developing optoelectronic for detection was highlighted. Furthermore, we try propose some new insights enhance explosives. We suggest employing photocatalysis principles sensitivity and molecular imprinting...
ZnO-CuO mesocrystal was prepared via topotactic transformation using one-step direct annealing of aqueous precursor solution and assembled into a H2S sensor. The mesocrystal-based sensor possesses good linearity high sensitivity in the low-concentration range (10-200 ppb). Compared to pure CuO, as-prepared exhibited superior sensing performance with response ranging from 8.6 152 % towards concentrations 10 ppb ppm when applied at optimized working temperature 125 °C. showed excellent...
The precise regulation of the electron-withdrawing/electron-donating strength in a probe is great significance for design reaction-based fluorescent probes with specific functionalities. Here, family excited-state intramolecular proton transfer (ESIPT)-based fluorescence turn-on sensing properties toward KMnO4 was designed by precisely modulating electron-withdrawing substituents located at para-position recognition group. It found that −F, −CHO, and −H as groups bound can specifically...
Overproduction of superoxide anions in the vascular wall contributes to endothelial dysfunction disease. A superoxide‐generating reduced β ‐nicotinamide adenine dinucleotide phosphate (NADPH) oxidase has recently been identified as a major source oxidative radicals tissues. We studied effects synthetic manganese‐containing dismutase (SOD) mimetic, M40403, on NADPH oxidase‐dependent generation and dysfunction. In rat aortic smooth muscle cells, (100 μ M ) markedly stimulated production...
Understanding the underlying physical chemistry governing nanomaterial-based electrical gas sensing process is pivotal for rational design of high-performance sensors. Herein, using a remarkable ppb-level NO2-gated field-effect nanosensor that based on reduced graphene oxide rGO/TiO2 nanoparticle heterojunction, as an exploratory platform, we have established generic model to quantitatively gain insight into correlation between measured source-drain (S-D) current and sorption thermodynamics...
Abstract A simple method combing Mn 2+ doping with a hierarchical structure was developed for the improvement of thin-film sensors and efficient detection explosives relevant to improvised explosive devices (IEDs). ZnS nanospheres (HNs) were prepared via solution-based route their sensing performances manipulated by doping. The responses based on HNs towards 8 generally increase firstly then decrease doped concentration, reaching climate at 5% . Furthermore, sensory array different levels...
Abstract The detection of ultralow NO 2 for practical applications remains a significant challenge because the two critical characteristics high sensitivity and good robustness are considerably unsatisfactory. Inspired by classification stimuli‐receiving signal‐conveying stimuli‐responsive procedure neuron in organisms, an internal micro‐Schottky junction introduced into chemiresistor is constructed as efficient transduction strategy to boost less concerned transducing stage further...

A photodetector and a room temperature optoelectronic gas sensor with excellent performance are realized by B. Y. Zu, X. C. Dou, co-workers, who hydrothermally synthesize CdS/ZnO core/shell nanowires using two-step process on page 738.

E-Beam inspection (EBI) is widely applied as in-line defect monitoring tool for 14nm semiconductor manufacturing fabs. Failure mechanisms can be identified by cross-sectioning on the specific detected EBI. Dark voltage contrast (DVC) and bright (BVC) are two typical types of e-Beam defects. In real practice, it much easier to validate DVC signal due its obvious detectability. On contrary, BVC verification with failure analysis very difficult various possibilities short path. accurately cross...
