these Newsletters as he is the Technical Consultant to ITIA and has contributed no less than 11 articles, beginning in 2003. This time, together with his colleague Matthias Weil of the Vienna University of Technology, he has been prompted by the spectacular colours of tungsten oxides to delve deeper into the science behind the phenomena. Tungsten trioxide (WO3) as a fine yellow powder (right) and grown to millimetre size (left) Newsletter – June 2013 
Preparation of nano-crystalline tungsten powders from gaseous WO2(OH)2
The industrial production of tungsten powder is carried out by the reduction of tungsten oxide powder via hydrogen. In this process, the size of the W particles is limited to particle sizes larger
Influence of Deposition Parameters on Optical Properties of Sputtered Tungsten Oxide Films
Thin films of tungsten oxide were deposited on glass substrates at different temperatures and O2/Ar ratios using DC Magnetron sputtering system. The samples were characterized using x-ray
Synthesis of Visible-Light Active Monoclinic WO3 by Thermal Oxidation of Tungsten Powder for Photoreduction of Cr(VI)
In this paper, visible-light-active monoclinic WO3 powders were synthesized by thermal oxidation of W powders at 200 – 1000 °C in air atmosphere. Morphology and crystal structure of annealed W
Synthesis of sulfated zirconia catalyst using sol–gel technique for alkane isomerization
In the present study, highly acidic sulfated zirconia catalysts were prepared using a facile sol–gel method. A superior catalytic activity of sulfated zirconia nanomaterial for isomerization of
Modification of optical and structural properties of DC magnetron sputtered tungsten oxide thin films for electrochromic application
The optical properties of tungsten oxide thin films prepared by a reactive DC magnetron sputtering technique were investigated. The influences of O 2 flow rates (15 and 18 sccm) and DC sputtering
Understanding the Potential of WO3 Based Sensors for Breath Analysis
TLDR
WO3 is reported to show high sensor responses to several biomarkers found in breath, e.g., acetone, ammonia, carbon monoxide, hydrogen sulfide, toluene, and nitric oxide, and modern material science allows WO3 samples to be tailored to address certain sensing needs.
