Corrosion-resistant and conductive Ti-Nb-O coatings tailored for ultra-low Pt-loaded BPPs and PTLs in PEM electrolyzers
David Kolenatý, JiÅà Äapek, Stanislav Haviar +6
We develop highly corrosion-resistant and conductive Ti-Nb-O coatings for metallic components -- bipolar plates (BPPs) and porous transport layers (PTLs) -- in PEM water electrolyz…
High-performance thermochromic multilayer coatings with W-doped VO2 nanoparticles dispersed in SiO2 matrix prepared on glass at a low temperature
Jaroslav Vlcek, Michal Kaufman, Elnaz M. Nia +5
We report a high-performance thermochromic VO2-based coating prepared by using a three-step process, consisting of magnetron sputter depositions of SiO2 films and V-W films and the…
Ultra-low-resistivity nitrogen-doped p-type Cu2O thin films fabricated by reactive HiPIMS
JiÅà Rezek, Jan Koloros, JiÅà HouÅ¡ka +5
We have successfully fabricated the nitrogen-doped cuprous oxide thin films on the amorphous standard soda-lime glass by reactive high-power impulse magnetron sputtering. The energ…
New polymorph γ-CuWO4 inspired by γ-CuMoO4: experimental identification and theoretical verification
Jiri Houska, Stanislav Haviar, Jiri Capek +4
In the context of our efforts to develop hydrogen gas sensors, two samples of ternary CuWO4 with the same crystalline structure have been prepared by two different non-equilibrium…
A low-temperature synthesis of strongly thermochromic W and Sr co-doped VO2 films with a low transition temperature
Michal Kaufman, Jaroslav Vlcek, Jiri Houska +4
The reversible semiconductor-to-metal transition of vanadium dioxide (VO2) makes VO2-based coatings a promising candidate for thermochromic smart windows, reducing the energy consu…
