Docket Number: 21-001. Applicant: Rice University, 6100 Main Street, Houston, TX 77005. Instrument: LightCrafter 4500 EVM. Manufacturer: Digi-Key Electronics, China. Intended Use: The LightCrafter 4500 will be used in an ongoing research study to develop a compact optical mapping scope that uses Digital Light Processing (DLP) technology to capture white light and auto-fluorescence images and actively project onto the oral mucosa a map highlighting areas at high risk for oral dysplasia and cancer, based on: Loss of collagen fluorescence (a signal of invasion & metastasis) and alterations in epithelial NAD(P)H and FAD fluorescence (a signal of de-regulated cellular energetics). With this device, we will design and assemble an optical system that allows for wide field imaging of the oral cavity, where the LightCrafter 4500 is aligned with the camera such that any area that can be imaged can also be projected upon. We will develop tracking algorithms to adjust the projected map as needed to ensure accurate positioning despite patient movement. The objective is to develop an optical imaging system that will detect high-risk areas of the oral mucosa and project high-risk maps onto the oral mucosa to guide clinicians on where to take a biopsy.

Docket Number: 21-004. Applicant: William Marsh Rice University, 6100 Main Street, Houston, TX 77005. Instrument: Angle-Resolved Photoemission Spectroscopy System. Manufacturer: Fermion Instruments, China. Intended Use: The technique of angle-resolved photoemission spectroscopy is a very specialized technique used to directly image the electronic structure of synthesized single crystalline materials or thin film materials. This technique is mainly used to study fundamental physical and electrical properties of materials, how electrons interact with each other leading to the insulating, metallic, or superconducting properties of materials for fundamental research. The measurement of electronic structure will provide important information on the fundamental physical origin of why a material is a good conductor or insulator or a superconductor. This will be beneficial towards new physics theories about solid state materials for academic purposes.

Docket Number: 21-009. Applicant: Yale University, BCT326, 15 Prospect Street, New Haven, CT 06511. Instrument: 1.25W@4K G-M Cryocooler. Manufacturer: CSIC PRIDE (NANJING) CRYOGENIC TECHNOLOGY CO., China. Intended Use: The instrument will be used to research on superconducting films synthesized in our lab. These phenomena can only be brought to life when cooled to cryogenic temperatures created with liquid helium. The transition temperature (Tc) and magnetic susceptibility of our superconductor samples from the resistive normal state to the zero-resistance superconducting states will be measured. The instrument would slowly cool the sample to low temperature (4 K = −269° C) and measure its resistance and magnetic susceptibility at the same time to find the transition temperature Tc. This cryocooler will help to cool our sample from room temperature to 4 K, which is 269 °C below the freezing point in a controlled way. The cooling power required here is essential to ensure that we can reach and maintain at 4 K temperature. The small formfactor and vacuum-compatible design is also required for compatibility reasons.
