Development of sensor materials based on metal oxide semiconductors (MOS) for selective
gas sensors is challenging for the tasks of air quality monitoring, early fire detection, gas …

Here we report a hierarchical flower-like SnO/SnO 2 gas sensing material for detecting
formaldehyde vapor at a low temperature. It was rationally designed and successfully …

Repetitive start-up and shut-down events in polymer electrolyte membrane fuel cells for
automotive applications lead to serious corrosion of the cathode due to an instantaneous …

Nanoscale inorganic materials such as quantum dots (0-dimensional) and one-dimensional
(1D) structures, such as nanowires, nanobelts and nanotubes, have gained tremendous …

A novel hierarchical heterostructure of α-Fe2O3 nanorods/TiO2 nanofibers with branch-like
nanostructures was fabricated using a simple two-step process called the electrospinning …

Gold nanoparticles (AuNPs) have been widely applied as highly efficient luminescence
quenchers in combination with a large variety of donor fluorophores. While the application of …

In this work the gas sensing properties of nanosensors fabricated by a “bottom-up” approach
in a FIB/SEM system based on a single Pd modified ZnO nanowire is investigated in detail …

Microelectromechanical-system (MEMS)-based semiconductor gas sensors are considered
one of the fastest-growing, interdisciplinary high technologies during the post-Moore era …

A composed morphology of iron oxide microstructures covered with very thin nanowires
(NWs) with diameter of 15–50 nm has been presented. By oxidizing metallic Fe …
