Publication number: 20240124827Abstract: The present invention provides a device for enrichment culture and gravity-type isolation of marine microorganisms in a high-pressure environment. The device includes an enrichment and multistage purification unit and a gravity-type isolation and culture unit. Under a high-pressure and low-temperature environment constructed to be consistent with a marine environment, the enrichment and multistage purification unit is used for realizing a process of enrichment and multistage purification of the marine microorganisms, obtaining a marine microorganism enrichment bacteria liquid and injecting the marine microorganism enrichment bacteria liquid into the gravity-type isolation and culture unit. The gravity-type isolation and culture unit is used for carrying out automatic streaking by means of gravity in the high-pressure environment to achieve solid isolation and culture of the marine microorganisms, such that culturability of the marine microorganisms is effectively improved.Type: ApplicationFiled: March 30, 2022Publication date: April 18, 2024Applicants: GUANGDONG LABORATORY OF SOUTHERN OCEAN SCIENCE AND ENGINEERING (GUANGZHOU), GUANGDONG UNIVERSITY OF TECHNOLOGYInventors: Jingchun FENG, Si ZHANG, Zhifeng YANG, Yi WANG, Yanpeng CAI, Song ZHONG

Publication number: 20240088629Abstract: A laser assembly, such as a flood illuminator, has laser (e.g., VCSEL) emitters on a substrate configured to emit optical signals. An optic structure of optically transparent material, such as a polymer, is formed directly on the substrate, and micro-optic elements are nano-imprinted on the optic structure. The micro-optic elements are arranged in optical communication with the optical signals emitted from the laser emitters to perform field mapping or other optical functions. The laser emitters are on the same surface of the substrate as the optic structure along with electrical contacts so forming the optic structure involves covering the electrical contacts with a protective layer, dispensing a polymer for the optic structure, cutting away portions of the optic structure, removing the remaining protective layer, and exposing the electrical contacts.Type: ApplicationFiled: September 13, 2022Publication date: March 14, 2024Inventors: Jason O'DANIEL, Pei-Song CAI, Hong-Zhi Liu, Francesco Schiattone

Publication number: 20230420917Abstract: VCSEL-based flood illuminators are fabricated to be compact and surface-mounted devices. A substrate is constructed as a panel array having top and bottom electrodes. Individual ones of the VCSEL dies are mounted in electrical communication with pairs of the top electrodes. The VCSEL dies are encased in an encasement disposed on the top surface of the substrate, and a diffuser structure is nano-imprinted adjacent each of the VCSEL dies. The encasement can use a potting resin and a polymer layer. The potting resin encases the VCSEL dies. The polymer layer is softer and is disposed on the potting resin. Nanoimprint lithography forms the diffuser structures in the polymer layer. The panel array is then singulated to form the individual VCSEL-based flood illuminators.Type: ApplicationFiled: June 24, 2022Publication date: December 28, 2023Inventors: Jason O'Daniel, Pei-Song Cai, Hong-Zhi Liu, Francesco Schiattone

Patent number: 11111571Abstract: A group of substantially nickel-free beta-titanium alloys have shape memory and super-elastic properties suitable for, e.g., medical device applications. In particular, the present disclosure provides a titanium-based group of alloys including 16-20 at. % of hafnium, zirconium or a mixture thereof, 8-17 at. % niobium, and 0.25-6 at. % tin. This alloy group exhibits recoverable strains of at least 3.5% after axial, bending or torsional deformation. In some instances, the alloys have a capability to recover of more than 5% deformation strain. Niobium and tin are provided in the alloy to control beta phase stability, which enhances the ability of the materials to exhibit shape memory or super-elastic properties at a desired application temperature (e.g., body temperature). Hafnium and/or zirconium may be interchangeably added to increase the radiopacity of the material, and also contribute to the superelasticity of the material.Type: GrantFiled: November 14, 2016Date of Patent: September 7, 2021Assignee: Fort Wayne Metals Research ProductsInventors: Song Cai, Jeremy E.
