  • Publication number: 20260167750
    Abstract: Novel bio-based polymers are described that may be chemically recycled to monomer at end of life. The polymers may be manufactured as fiber, molded parts, film, coatings, etc. that are more efficiently recycled than commodity plastics. Specific embodiments exhibit performance advantages arising from the biofunctionalization of monomers over related designs where such functionality is absent.

  • Publication number: 20220175988
    Abstract: A UV-C decontamination apparatus is used to decontaminate PPEs, such as respiratory masks. The apparatus is formed from a 3D printing process which makes the manufacture and use widespread. The apparatus includes a 3D printed chamber and a lid for enclosing the chamber. At least one UV-C lamp is supported in the chamber. Activation of the lamp is designed to decontaminate the mask supported in the chamber from the lid. An electronic switch assembly permits activation of the lamp only upon locking closure of a lid to the chamber. In a further embodiment, the hook is rotatable on the lid so as to rotate the mask in the chamber upon lamp activation.

  • Patent number: 8296358
    Abstract: An exemplary embodiment of the present invention provides a method of processing a file system transaction in a distributed file system. The method includes receiving a transaction request from a computer, wherein the transaction request includes file data to be stored and a first segment identifier that determines a destination of the file data. The method also includes generating a first distributed journal record corresponding to the file data. The method also includes generating a first file operation request based, at least in part, on the transaction request. The method also includes sending the first file operation request to a first segment server corresponding to the first segment identifier, wherein the first segment server generates a second distributed journal record corresponding to the file data on a memory device associated with the first segment server.

  • Publication number: 20110209987
    Abstract: A nanocluster source constituted of: a cooled aggregation chamber; a magnetron arranged to sputter a target, the magnetron in communication with the cooled aggregation chamber such that sputtered atoms of the target are received within the cooled aggregation chamber; a vacuum source in communication with the cooled aggregation chamber; a source of at least one noble aggregation gas in communication with the cooled aggregation chamber; and a source of hydrogen gas in communication with the cooled aggregation chamber. Advantageously, the hydrogen gas prevents oxidation of the target and silicon film covering a cooled inner surface of the aggregation chamber, and reduces the surface tension of the formed nanoclusters.

  • Patent number: 7391024
    Abstract: An apparatus is disclosed for the conversion of radiation. The apparatus includes a mesoscopic sized region, an interface surrounding the mesoscopic sized region and contacting the mesoscopic region to form an energetic barrier sufficient to spatially confine free carriers in the mesoscopic sized region, and a matrix material surrounding the interface. At least one of the interface and the matrix material provides radiative recombination of the free carriers.

  • Patent number: 7193210
    Abstract: Methods and specialized media adapted to the formation of a steady-state, non-equilibrium distribution of free carriers using mesoscopic classical confinement. Specialized media is silicon-based (e.g., crystalline silicon, amorphous silicon, silicon dioxide) and formed from mesoscopic sized particles embedded with a matrix of wide-bandgap material, such as silicon dioxide. An IR to visible light imaging system is implemented around the foregoing.

  • Publication number: 20060120353
    Abstract: The systems and methods for deploying VoIP telecommunication services. The systems include at least one service package that has a set of instructions for carrying out, hosting and/or deploying a VoIP telecommunications service. The system also includes a runtime environment, or process, that is capable of processing instructions stored in the one or more service packages for the purpose of carrying out the VoIP service deployment. The system further includes one or more adapters, each of which is capable of interfacing the system to the external network environment through which the communication service will be deployed. Optionally and preferably the system may also include an integrated development environment for allowing a user to develop a service package which can be executed within the runtime environment for directing the external network, through the adapters, to implement the user developed service.
