20130217801 | SYNTHESIS OF DIOXYHETEROCYCLE-BASED POLYMERS - A method of polymerization for the preparation of conjugated polymers and copolymers comprising dioxypyrrole and/or dioxyfuran repeating units involves the halogen, N-haloimide, or N-haloamine promoted polymerization of monomers and/or oligomers comprising one or more dioxypyrrole and/or dioxyfuran units. The polymerization can be carried out over a wide range of temperatures and can be carried out with or without a solvent. The monomers allow the preparation of polymers having an oligomeric repeating unit comprising a conjugated unit other than a dioxypyrrole or dioxyfuran that is bound to two dioxypyrrole or dioxyfuran units. | 08-22-2013 |

20160122476 | Method for Preparing Dioxyheterocycle-Based Electrochromic Polymers - A method for preparing a conjugated polymer involves a DHAP polymerization of a 3,4-dioxythiophene, 3,4-dioxyfuran, or 3,4-dioxypyrrole and, optionally, at least one second conjugated monomer in the presence of a Pd or Ni comprising catalyst, an aprotic solvent, a carboxylic acid at a temperature in excess of 120° C. At least one of the monomers is substituted with hydrogen reactive functionalities and at least one of the monomers is substituted with a Cl, Br, and/or I. The polymerization can be carried out at temperature of 140° C. or more, and the DHAP polymerization can be carried out without a phosphine ligand or a phase transfer agent. The resulting polymer can display dispersity less than 2 and have a degree of polymerization in excess of 10. | 05-05-2016 |

20140318731 | EXTRACTION FROM LARGE THERMAL STORAGE SYSTEMS USING PHASE CHANGE MATERIALS AND LATENT HEAT EXCHANGERS - An energy storage method and apparatus for extraction from large thermal storage systems using phase change materials and latent heat exchangers. This includes thermal heat extraction from, and charging of a large thermal storage tank containing thousands of megawatt hours of thermal energy, using the phase change of heat collection fluid and the phase change of molten phase change material for thermal storage use in generating electricity, steam, or for other industrial processes as implemented in the field of solar energy collection, thermal storage and extraction. The method and apparatus continuously removes thermal resistance that comes from the phase change material allowing operation at a high rate of efficiency. A heat exchanger is provided inside the storage tank thereby reducing heat losses, capital costs and space requirements compared to existing thermal storage systems. | 10-30-2014 |
