The process of making a stack of parallel sheets of graphene starts with a chemical vapor deposition process (I) to make a graphene sheet with a polymer coating; these layers are then stacked (II), folded and cut (III) and stacked again and pressed, multiplying the number of layers. The team used a related method the team to produce scroll-shaped fibers.

Borrowing from pastry chefs, engineers create nanolayered composites

Method to stack hundreds of nanoscale layers could open new vistas in materials science.

This diagram depicts the way a new surface treatment can improve the efficiency and longevity of perovskite materials for use in applications such as fuel-cell electrodes. Within the bulk of the material (bottom left) oxygen vacancies shown as “holes” are distributed throughout the material, and cause intense chemical reactivity. But on the surface, many of those vacancies get filled by oxygen...
