Decreasing the time response of calibration-free pH sensors based on tungsten bronze nanocrystals
(Elsevier, 2017)
A considerable improvement of time constants of tungsten bronze pH sensors was achieved by decreasing the crystal size of the tungsten bronze previously reported by the authors. Experiments have been performed on the basis ...
Behaviour of tungsten in fusion environment: Damages by hydrogen
(International Journal of Science and Research, 2020-02)
The analysis of the interaction of hydrogen and their isotopes with tungsten is important, since this material is a strong candidate to form the first wall of fusion reactors for both magnetic and inertial confinement, and ...
Influence of Tungsten Dopant on Sintering and Curie Temperatures of Ba(Zr0.10Ti0.90)O-3 Ceramics
(Taylor & Francis Ltd, 2008-01-01)
Ba(Zr0.10Ti0.90)O3 (BZT10) and W+ 6 substituted BZT ceramics (BZT10:W) were prepared by mixed oxide method. The effect of W+ 6 addition in the BZT was evaluated by X-ray diffraction (XRD), dilatometer analysis, microstructural ...

Tungsten oxide nanowire on copper surfaces: A DFT model
(Royal Society of Chemistry, 2016-09)
We studied a model of a one dimensional tungsten oxide nanowire on a reconstructed Cu(110) surface by density functional theory calculations. The effect of oxygen vacancies on the electronic structure was analyzed (DOS). ...
Effects of tungsten carbide thermal spray coating by HP/HVOF and hard chromium electroplating on AISI 4340 high strength steel
(2001-04-16)
In cases of decorative and functional applications, chromium results in protection against wear and corrosion combined with chemical resistance and good lubricity. However, pressure to identify alternatives or to improve ...
