  • Patent number: 11799093
    Abstract: Disclosed are a catalyst electrode for a fuel cell, a method for fabricating the catalyst electrode, and a fuel cell including the catalyst electrode. The presence of an ionomer-ionomer support composite in the catalyst electrode prevents the porous structure of the catalyst electrode from collapsing due to oxidation of a carbon support to avoid an increase in resistance to gas diffusion and can stably secure proton channels. The presence of carbon materials with high conductivity is effective in preventing the electrical conductivity of the electrode from deterioration resulting from the use of a metal oxide in the ionomer-ionomer support composite and is also effective in suppressing collapse of the porous structure of the electrode to prevent an increase in resistance to gas diffusion in the electrode. Based on these effects, the fuel cell exhibits excellent performance characteristics and prevents its performance from deteriorating during continuous operation.

  • Patent number: 9751758
    Abstract: A method for lattice design via multivalent linkers (LDML) is disclosed that introduces a rationally designed symmetry of connections between particles in order to achieve control over the morphology of their assembly. The method affords the inclusion of different programmable interactions within one linker that allow an assembly of different types of particles. The designed symmetry of connections is preferably provided utilizing DNA encoding. The linkers may include fabricated “patchy” particles, DNA scaffold constructs and Y-shaped DNA linkers, anisotropic particles, which are preferably functionalized with DNA, multimeric protein-DNA complexes, and particles with finite numbers of DNA linkers.

  • Patent number: 9650556
    Abstract: The present disclosure relates to a method of encapsulating microcapsules containing relatively high temperature phase change materials and the microcapsules so produced. The microcapsules are coated with an inorganic binder, film former and an inorganic filler. The microcapsules may include a sacrificial layer that is disposed between the particle and the coating. The microcapsules may also include an inner coating layer, sacrificial layer and outer coating layer. The microcapsules are particularly useful for thermal energy storage in connection with, e.g., heat collected from concentrating solar collectors.

  • Patent number: 9486732
    Abstract: Adsorbent compositions useful in adsorption and separation processes are made using silicone-derived binding agents. The adsorbent compositions are made from crystallite aluminosilicate particles bound with silicone-derived binding agents, and optionally small amounts of a clay binder, to form agglomerated crystallite particles and are calcined to volatilize the organic components associated with the silicone-derived binding agents. The agglomerated crystallite particles have superior pore structures and superior crush strengths at low binder concentrations and exhibit enhanced N2 adsorption rates and capacities when used in air separation processes.
