  • Publication number: 20220221277
    Abstract: According to various embodiments, a method for reducing heading error in a magnetometer that uses Rb-87 atoms is disclosed. The method includes varying a direction and magnitude of a magnetic field at different spin polarization regimes. According to various embodiments, a magnetometer adapted for reduced heading error is disclosed. The magnetometer includes a multipass cell containing Rb-87 vapor, a pump laser operated in a pulse mode that is synchronous with a Larmor frequency, and two orthogonal probe lasers configured to rotate to vary a direction and magnitude of a magnetic field at different spin polarization regimes.

  • Publication number: 20220040905
    Abstract: Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.

  • Patent number: 10662284
    Abstract: A method for preparing blends of at least two polymer components is described herein. The disclosed method generally involves controlling relative molecular weights and ratios of the two or more polymer components by selecting a first initiator, a second initiator, and a monomer, and subjecting the reactants to conditions suitable to polymerize the monomer based at least in part on the first and second initiators in connection with obtaining the polymeric blend. The second initiator is advantageously selected based on one or more characteristics associated therewith, based on a characteristic of the first initiator. A polymeric blend produced according to such a method is also provided herein.

  • Publication number: 20180051156
    Abstract: A method for enhancing/accelerating the depolymerization of polymers (e.g., those containing hydrolyzable linkages) is described herein. The disclosed method generally involves contacting a polymer comprising hydrolyzable linkages with a solvent and an alcohol to give a polymer mixture in which the polymer is substantially dissolved, wherein the contacting is conducted at a temperature at or below the boiling point of the polymer mixture. A resulting depolymerized polymer can be separated therefrom (including, e.g., monomers and/or oligomers). Such methods can be conducted under relatively mild temperature and pressure conditions.
