  • Publication number: 20180342002
    Abstract: A ring design machine receives one or more selections of gemstones and one or more selections of settings and allows a user to “mix and match” gemstones and settings and view a selected gemstone in a compatible setting for that gemstone. To present the gemstone in the setting, the ring design machine presents a combination image that depicts the gemstone in the setting. The ring design machine, which may be implemented using a computer programmed by software, may present the combination image to the user in response to receiving a selection of the gemstone and a selection of the setting from the user via a network.

  • Publication number: 20180244992
    Abstract: This invention provides a groundbreaking approach to PLNPs and their preparation. In particular, the synthetic methodology disclosed herein fundamentally differs from the traditional solid-state annealing reactions that require extreme and harsh reaction conditions. In one unique aspect of the invention, a simple, one-step mesoporous template method utilizing mesoporous silica nanoparticles (MSNs) is disclosed that affords in vivo rechargeable NIR-emitting mesoporous PLNPs with uniform size and morphology. In another unique aspect of the invention, the novel synthetic approach is based on aqueous-phase chemical reactions conducted in mild conditions, resulting in uniform and homogeneous PLNPs with desired size control (e.g., sub-10 nm).
