摘要:
Water- and ion-conducting membranes composed of sulfonated statistical arylvinyl polymers, the arylvinyl polymer comprising at least one arylvinyl monomer and at least one olefin monomer and wherein aromatic moieties derived from the arylvinyl monomer are at least partially sulfonated, are used as proton-conducting membranes for production of electricity, as water-conducting membranes for humidification of fuel gases in fuel cells and heat and moisture exchange in heating/ventilation/air conditioning systems. Water-conducting membranes composed of sulfonated arylvinyl polymers, the arylvinyl polymer comprising at least one arylvinyl monomer and wherein aromatic moieties derived from the arylvinyl monomer are at least partially sulfonated are used for desalination of seawater.

Energy storage devices that include a solid multilayer electrolyte are provided. In certain embodiments, the energy storage devices disclosed herein can exhibit behavior analogous to an electrochemical battery at lower voltages, but can transition to electrostatic capacitor behavior as voltages rise. The energy storage devices, methods, and systems disclosed herein can preferably be advantageous by providing a large total energy storage capacity.
摘要:
Particular embodiments disclosed herein relate to methods, compositions, and systems relating generally to heating, ventilation, and air conditioning (HVAC) systems, and more specifically, to HVAC systems that transfer sensible and/or latent energy between air streams, humidify and/or dehumidify air streams. In certain embodiments, a polymeric membrane is utilized for fluid exchange, with or without an additional support. Certain embodiments allow for individual regulation of air temperature and humidity.

The present invention is a novel block copolymer containing a controlled distribution copolymer block of a conjugated diene and a mono alkenyl arene, where the controlled distribution copolymer block has terminal regions that are rich in conjugated diene units and a center region that is rich in mono alkenyl arene units. Also disclosed is a method for manufacture of the block copolymer.
摘要:
A multi-layer circuit panel assembly is formed by laminating circuit panels with interposers incorporating flowable conductive material at interconnect locations and a flowable dielectric materials at locations other than the interconnect locations. Excess materials are captured in reservoirs such as within vias in the circuit panels and apertures in interior elements within the interposers. The flowable materials of the interposers, together with the reservoirs, allow the interposers to compress and take up tolerances in the components. The flowable dielectric material encapsulates conductors on the surfaces of the circuit panels.

Systems and methods for cooling and/or separating a component from a fluid are disclosed herein. Such systems and methods can include one or more of a separator (e.g., a dehumidifier), a chiller, and/or an expirator, each of which can include a selective transfer membrane. Such systems and methods can be used for a wide variety of applications including, for example, cooling and/or dehumidifying air.
摘要:
The present invention pertains to products and processes relating to sulfonating molecules, including nucleic acids, amino acids, peptides, polypeptides, oligomers, polymers, and copolymers. The disclosed process allows for a uniform and controlled level of sulfonating molecules. The sulfonated molecules produced by the disclosed process exhibit a high degree of uniform sulfonation as well as improved properties.
摘要:
A method of assembling a multilayer laminate interconnection board, particularly boards in which each layer preferably includes copper conductors on polyimide film layers, involves adhesively joining individual layers of wired film initially onto an auxiliary pin carrier substrate and then onto a previously laminated layer. After each layer is aligned and adhesively joined to the immediately preceeding layer, holes are formed through the layer. Metal is deposited into the holes for electrically connecting conductors on the top surface of the last layer to a via located on the immediately preceeding layer. The process is repeated for each layer of the multilayer laminate interconnection board until the entire board is completely assembled. Alternatively, layers containing preformed and metalized holes at the location of a respective via in a particular layer are aligned and adhesively laminated.
