Yolk-shell nanocrystals with movable gold yolk: Next generation of photocatalysts

Owing to their unique permeable, hollow shell structures with inner, movable cores, yolk-shell nanocrystals are suitable for a wide variety of applications. Yolk-shell nanocrystals consisting of a gold core with various semiconductor shells have been developed using a novel sequential ion-exchange process. These metal-semiconductor yolk-shell nanocrystals can serve as highly effective photocatalysts for many applications.

Robotic touch sensors are not just skin deep

Researchers argue that the problem that has been lurking in the margins of many papers about touch sensors lies in the robotic skin itself.
