ITU-UNICEF initiative establishes new base for bringing every school online and promoting digital development

New research has underlined the surprising extent to which pervasive surveillance of people and their habits is powered by computer vision research – and shone a spotlight on how vulnerable individuals and communities are at risk. Analyses of over 40,000 documents, computer vision (CV) papers and downstream patents spanning four decades has shown a five-fold increase in the number of computer vision papers linked to downstream surveillance patents. The work also highlights the rise of obfuscating language that is used to normalise and even hide the existence of surveillance. 

The metal-supported reversible protonic ceramic cell (MS-rPCC) combines the dual advantages of metal support and proton conduction, enabling efficient low-temperature operation, high mechanical strength, and exceptional thermal cycling stability. However, a critical challenge in MS-rPCC fabrication lies in element diffusion from the metal support and the thermal expansion mismatch between the metallic and ceramic phases. To address this issue, a pure nickel metal support and a newly developed transition layer (80 wt.% NiO–20 wt.% BaZr0.1Ce0.7Y0.2O3-δ, BZCY) were employed to mitigate thermal expansion mismatch, thereby enhancing the performance and stability of the MS-rPCC. This work presents a novel approach to facilitate the commercialization and widespread application of MS-rPCC technology.
