  • Publication number: 20190229387
    Abstract: Solar rechargeable battery combines the advantages of photoelectrochemical devices and batteries and has emerged as an attractive alternative to artificial photosynthesis for large-scale solar energy harvesting and storage. Due to the low photovoltages by the photoelectrodes, however, most previous demonstrations of unassisted photocharge have been realized on systems with low open circuit potentials (<0.8 V). In response to this critical challenge, here the present disclosure shows that the combined photovoltages exceeding 1.4 V can be obtained using a Ta3N5 nanotube photoanode and a GaN nanowire/Si photocathode with high photocurrents (>5 mA/cm2). The photoelectrode system makes it possible to operate a 1.2 V alkaline anthraquinone/ferrocyanide redox battery with a high ideal solar-to-chemical conversion efficiency of 3.0% without externally applied potentials.

  • Patent number: 10336781
    Abstract: Highly active, recoverable and recyclable transition metal-based metathesis catalysts and their organometallic complexes including dendrimeric complexes are disclosed, including a Ru complex bearing a 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and styrenyl ether ligand. The heterocyclic ligand significantly enhances the catalytic activity, and the styrenyl ether allows for the easy recovery of the Ru complex. Derivatized catalysts capable of being immobilized on substrate surfaces are also disclosed. The present catalysts can be used to catalyze ring-closing metathesis (RCM), ring-opening (ROM) and cross metatheses (CM) reactions, and promote the efficient formation of various trisubstituted olefins at ambient temperature in high yield.

  • Patent number: 9370881
    Abstract: The invention features a method for producing replicas of a desired structure, a master and a mold obtained from it for use in such a method. The master includes a desired structure (200) to be reproduced and an additional structure (206, 208) that assists in removal of the master from a mold, e.g. by permitting portions of the mold on opposite sides of the additional structure to flex away from one another when the master is removed from the mold. The method includes immersing the master comprising the desired structure (200) and the additional structure (206, 208) in a molding material (142), solidifying the molding material (142) to make a mold, removing the master from the mold and using the mold to produce replicas of the desired structure (200).
