Materials Engineering Strategies to Control Metal Oxides Nanowires Sensing Properties
Advanced Materials Interfaces, Volume 9, Issue 12, April 22, 2022., 2022 Since last two decades, nanostructured metal oxides (MOXs) are extensively explored for gas sensing applications. In particular, MOXs nanowire‐based conductometric gas sensors show superior performance due to their unique physical/chemical properties.

Nanostructuring Germanium Nanowires by In Situ TEM Ion Irradiation
Particle &Particle Systems Characterization, Volume 38, Issue 12, December 2021., 2021 Germanium nanowires were irradiated with a 300 keV xenon ion beam in situ within a transmission electron microscope inducing the formation of nanopores. The features of the nanostructures are revealed by using data acquired in situ at various temperatures and 3D reconstruction of the nanostructured nanowire.

Novel Christmas Branched Like NiO/NiWO4/WO3 (p–p–n) Nanowire Heterostructures for Chemical Sensing
Advanced Functional Materials, Volume 31, Issue 38, September 16, 2021., 2021 A simple, high yield two‐step vapor‐phase growth method is implemented for the fabrication of novel heterostructures of (p/p/n) NiO/NiWO4/WO3. These heterostructures exhibit excellent sensing performance toward different oxidizing and reducing gases by modulating their optimal working temperature and charge carrier transport and hence show a high ...

Spatio‐Spectral‐Temporal Imaging of Fast Transient Phenomena Using a Random Array of Pinholes
Advanced Photonics Research, Volume 2, Issue 2, February 2021., 2021 An optical chaotic wave generator is used to map 4D spatio‐spectral locations of a point to unique 2D random monochrome intensity distributions. A 5D high‐speed imaging technology is developed based on the map to convert a monochrome high‐speed camera into a 3D color high‐speed camera.
