  • Patent number: 11440975
    Abstract: The invention relates a process for preparing a cross-linked starch-based polymer comprising the following steps: 1) dissolving a starchy material in a suitable solvent to form a starchy material solution; and 2) adding a episulfide of formula (I), wherein R1, R2, R3 and R4 are independently selected from hydrogen and (C1-C3)alkyl in the starchy material solution in order to obtain the disulfide crosslinked starch-based polymer. In another aspect the invention concerns a disulfide-cross-linked starch-based polymer obtainable by the process of the invention, that is characterized by only disulfide bridges.

  • Patent number: 9987614
    Abstract: The invention relates a process for preparing a microporous carbon material comprising the following steps: i) providing a cross-linked polymer obtainable by reacting either A1) a maltodextrin deriving from starch comprising amylose in the range from 25 to 50% expressed as dry weight relative to the dry weight of the starch or A2) a cyclodextrin with an organic aromatic dianhydride in a mass ratio of either maltodextrin or cyclodextrin with respect to the organic aromatic dianhydride in the range of 1:0.50 to 1:2, ii) pyrolyzing at a range from 700 to 900° C. with a heating ramp in the range from 5° C./min to 30° C./min in a inert gas flux; and iii) cooling the obtained residue. The microporous carbon material obtainable by the process of the invention consists of micropores having pore size distribution in the range from about 6 to about 16 ? and is used as absorber for liquids and gases.

  • Patent number: 8643536
    Abstract: A positioning system for radio frequency devices includes a two-way radio antenna, for vehicles, having a transmitting and a receiving element. Reference antennas have retro-directive arrays which can shape the signal beams in elevation; polarize transmission and reception signals according to a circular or a linear polarization, the polarized transmission retro-directively reflecting signals having the same polarization as the incident ones in the case of circular polarization, or retro-directively reflecting signals having orthogonal polarization in the case of linear polarization. An encoder is included for transmitting an identification code of the reference antenna. A controller processes the spatial and temporal data resulting from communication through the radio waves transmitted and received by the vehicle antennas and reflected by the reference antennas. The controller calculates the distance of the vehicle from the reference antennas that have reflected the signal transmitted by the antennas.
