Gas sensors have been fabricated using the single-crystalline SnO2 nanobelts. Electrical characterization showed that contacts were ohmic and nanobelts sensitive to environmental polluting species like CO NO2, as well ethanol for breath analyzers food control applications. The sensor response, defined relative variation in conductance due introduction of gas, is 4160% 250 ppm −1550% 0.5 NO2 at 400 °C. results demonstrate potential fabricating nanosized integrity a single nanobelt with...
In the past few years, progress has been achieved in synthesis, structural characterization and physical properties investigation of nanostructures. Due to their peculiar characteristics size effects, these materials often show some novel that are different from those bulk, great interest both for fundamental study potential nanodevice applications. this paper, topics covered worldwide most recent research field quasi one-dimensional inorganic structures gas sensing promising results at...
Three-dimensional (3D) tungsten oxide nanowire networks have been demonstrated as a high-surface area material for building ultrasensitive and highly selective gas sensors. Utilizing the 3D hierarchical structure of networks, high sensitivity has obtained towards NO2, revealing capability to detect concentration low 50ppb (parts per billion). The distinctive selectivity at different working temperatures is observed various gases. results highlight that nanobelts (nanowires) technology can be...
Today, the self-assembled monolayer (SAM) approach for surface functionalization is regarded as highly versatile and compelling, especially in immobilization of biomolecules fabrication novel supramolecular architectures.
Abstract The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities advance the sustainability quality our lives—e.g. via smart homes, cities, healthcare, logistics, Industry 4.0, precision agriculture. realization full potential these applications critically depends on availability easy-to-make, low-cost sensor technologies. Sensors based printable electronic materials offer ideal...
SnO2 nanocrystals were prepared by injecting a hydrolyzed methanol solution of SnCl4 into tetradecene dodecylamine. The resulting materials annealed at 500 °C, providing 6−8 nm nanocrystals. latter used for fabricating NO2 gas sensing devices, which displayed remarkable electrical responses to as low 100 ppb concentration. characterized conductometric measurements, X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), and cathodoluminescence (CL) spectroscopy....
It is almost a decade since the first presentation of metal oxide nanowires as chemical sensors. Significant advances have been made both in terms preparation procedures and their integration into functional sensing devices, whilst progress fundamental understanding properties has slow. In fact, full still remains challenge that wisely approached different ways. this article we review most recent developments bottom up top down approaches for applications
ZnO−TiO2 nanocomposites were synthesized by an innovative chemical vapor deposition (CVD) strategy, based on the initial growth of ZnO nanoplatelets (host) and subsequent dispersion TiO2 nanoparticles (guest).
