Summary: High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method and used as a catalyst for degrading harmful textile pollutant Rose Bengal dye under sunlight with a high efficiency of 96% degradation rate after 3 hours. The enhancement in degradation efficiency was mainly attributed to the decrease in band gap and charge carrier recombination rate, with a possible degradation mechanism proposed based on the generation of oxygen vacancies due to the decoration of Ag on the CeO2 surface.

Summary: This paper reports on a new optical tactile sensor based on multiple scattering in a porous material with a viscoelastic phase-separated structure fabricated by a sol-gel method. The sensor shows an opposite light intensity change compared to conventional polymer foams due to Mie multiple scattering. A simple tactile sensor using a macroporous monolith and a photo reflector was fabricated based on this finding. Sensors using sol-gel derived macroporous materials have the potential to be thinner and provide improved surface tactile sensation compared to foam materials.
