This invention focuses on the design of a fully interchangeable hub-droplet device apparatus for multiple droplet generation in parallel. The novel central hub combined with interchangeable chip configuration allows the use of different planar droplet generation devices that can be replaced and exchanged as needed. By separating the central housing hub which distributes incoming liquids into…

Livermore researchers have developed a method of fabricating functional polymer-based particles by crosslinking UV-curable polymer drops in mid-air and collecting crosslinked particles in a solid container, a liquid suspension, or an air flow. Particles could contain different phases in the form or layered structures that contain one to multiple cores, or structures that are blended with…

The novel LLNL technique uses electric fields to drive and control assembly. In the literature such methods have heretofore only formed disordered ensembles. This innovative method increases local nanocrystal concentration, initiating nucleation and growth into ordered superlattices. Nanocrystals remain solvated and mobile throughout the process, allowing fast fabrication of ordered…
