Combinations, Not a Solo Signal, Strengthen Immune Response (2 of 3)
A microbullet traveling at supersonic speed is captured in this composite of three timed images as it makes its way toward a suspended sheet of multilayer graphene. Experiments carried out at Rice ...
Graphene Performs Well at the Shooting Range (4 of 4)
Jae-Hwang Lee briefly shows how the micro-ballistic experiment was performed using the advanced laser induced projectile impact test (a-LIPIT) apparatus. This material relates to a paper that appeared...
Surface Structure as the Secret to Super-Repellency (3 of 3)
This is a comparison of liquid repellency on a smooth Teflon® surface and a superomniphobic silica surface. Three liquids of water, methanol and FC-72, are used to illustrate the wetting properties of...
Surface Structure as the Secret to Super-Repellency (2 of 3)
This video shows water, methanol, and FC-72 beading and rolling on a superomniphobic silica surface. In contrast, the droplets spread spontaneously on smooth silicon dioxide (i.e., the outer frames of...
Surface Structure as the Secret to Super-Repellency (1 of 3)
This video shows droplets of water, methanol, and FC-72 (a chlorinated liquid) bouncing on surfaces with doubly re-entrant silica posts. Videos were filmed at 6000 fps and replayed 20 times slower at ...
