Book review: Nanostructured Gas Sensors Ankur Gupta and Gulshan Verma (eds.) | Review by Axel Mainzer Koenig The authors have produced a comprehensive perspective on nanostructured gas sensors that could be of interest to undergraduate and graduate students as well as researchers in materials science, physical chemistry and nano-engineering. The readers are introduced to gas sensing through various principles of catalytic, thermal conductivity and electrochemical sensors. Metal oxide nanostructures are particularly covered in detail for improving the performance of gas sensors through nanoparticles of noble gases, metal doping or mixing with other nanomaterials. The author has also provided supporting chapters on the basics of nanomaterials and nanostructures. This is extended by coverage of imaging modalities (SEM/TEM, atomic force microscopy) and additional analytical methods like UV visible and Fourier IR spectroscopy and X-ray diffraction methods. Readers interested in fabrica...
