Impact of TiO2-II phase stabilized in anatase matrix by high-pressure torsion on electrocatalytic hydrogen production

Electrocatalysis using renewable energy sources provides a clean technology to produce hydrogen from water. Titanium oxide is considered as a potential electrocatalyst not only for hydrogen production but also for CO2 conversion. In this study, to enhance the cathodic electrocatalytic activity of TiO2, the phase composition on TiO2 surface is modified by inclusion of high-pressure TiO2-II phase using high-pressure torsion (HPT) straining. Detailed spectroscopic studies revealed that the energy band gap is reduced and the valence band energy increased with increasing the TiO2-II fraction. The highest electrocatalytic activity for hydrogen production was achieved on an anatase-rich nanocomposite containing TiO2-II nanograins

Assessment of Multi-Plenoptic 2.0 Camera Depth Maps for DIBR

International audienceWe aim to evaluate the depth map quality by the plenoptic 2.0 cameras for DIBR applications, by simulating a multi-plenoptic camera array, and synthesizing virtual images based on the obtained color and depth maps. The real-time generated depth maps by plenoptic cameras are compared with the offline and high-quality depth maps estimated by the MPEG-I Depth Estimation Reference Software (DERS). Results show that synthesized virtual image quality obtained by RGBD plenoptic cameras has acceptable quality for real-time DIBR applications, but lower than using the depth estimated by DERS, due to a loss of inter-view depth consistency
