The superimposed schematic illustrates e-beam direct writing of nanoscale vertical staircases (SEM inset) on a substrate with microscale grayscale topography. The initial grayscale patterns were ...

said the project leader, Associate Prof Qi Ge from SUSTech, "In our approach, the computationally designed grayscale patterns are employed to realize microlens profiles upon one single UV exposure ...

A grayscale pattern used to create a self-folding flower is projected into a glass container. Light from the pattern forms a solid polymer which is differentially crosslinked, creating stress in ...
