Patent number: 11499248Abstract: An electric field drives nanocrystals dispersed in solvents to assemble into ordered three-dimensional superlattices. A first electrode and a second electrode 214 are in the vessel. The electrodes face each other. A fluid containing charged nanocrystals fills the vessel between the electrodes. The electrodes are connected to a voltage supply which produces an electrical field between the electrodes. The nanocrystals will migrate toward one of the electrodes and accumulate on the electrode producing ordered nanocrystal accumulation that will provide a superlattice thin film, isolated superlattice islands, or coalesced superlattice islands.Type: GrantFiled: February 9, 2018Date of Patent: November 15, 2022Assignee: Lawrence Livermore National Security, LLCInventors: Yixuan Yu, Joshua D.

Patent number: 11305252Abstract: An ultra low density film and an ultra low density solid material are produced by the steps of providing a vessel, introducing two immiscible fluids into the vessel, adding nanocrystals to at least one of the two immiscible fluids, applying a shear force to the two immiscible fluids and the nanocrystals in a manner that causes the nanocrystals to self-assemble and form colloidosomes. The colloidosomes amass and evaporation of the two fluids produces dried colloidosomes. The ultra low density self-assembled colloidosomes are hollow self-assembled colloidosomes, which are formed into the ultra-low density film and the ultra-low density solid.Type: GrantFiled: October 24, 2018Date of Patent: April 19, 2022Assignees: Lawrence Livermore National Security, LLC, Carnegie Mellon UniversityInventors: Christine A Orme, Sarah Baker, Yixuan Yu, Shelley L Anna, Charles Sharkey
