An efficient CuO/rGO/TiO2 photocatalyst for the synthesis of benzopyranopyrimidine compounds under visible light irradiation

Maryam Mirza-Aghayan, Mandana Saeedi, Rabah Boukherroub

This study reports the synthesis of CuO/rGO/TiO 2 in coupling reaction under visible light irradiation. Its photocatalytic performance was explored in a pseudo 4-component and a domino reaction for the synthesis of benzopyranopyrimidine compounds. It can be recovered and recycled for 5 runs.

On overtravel and skate in cantilever-based probes for on-wafer measurements

Steve Arscott

Due to the deformability of a microcantilever-based probe, there is an interesting and subtle interplay between the probe overtravel, the tip skate on the surface, and the ultimate tangency of the tip of the probe with the wafer surface. The relationship between these parameters is described here.…
