  • Publication number: 20190301437
    Abstract: A gravity oscillating system which comprises a looped and suitably substantially circular track around which a heavy mass such as a ball travels in use, the track being supported from above or below to oscillate up and down as the ball travels around the track, and there being a power transfer mechanism linked to the track to be moved by the track as the track oscillates, the power transfer mechanism being linked to an electrical generator/dynamo whereby the movement is used to generate electrical energy and wherein the system has an oscillating electromagnetic drive comprising a plurality of electromagnets in an array around the track and which are successively momentarily energized to urge each successive part of the track around the track in a direction, upwards or downwards, to cause the track to dip down ahead of the rolling mass, without the drive contacting the track.

  • Patent number: 10304636
    Abstract: An oxadiazole dye for use as an organic photosensitizer. The oxadiazole dye comprising donor-?-spacer-acceptor type portions in which at least one of an oxadiazole isomer acts as a ?-conjugated bridge (spacer), a biphenyl unit acts as an electron-donating unit, a carboxyl group act as an electron acceptor group, and a cyano group acts as an anchor group. An optional thiophene group acts as part of the ?-conjugated bridge (spacer). The dye for use as organic photosensitizers in a dye-sensitized solar cell and in photodynamic therapies. Computational DFT and time dependent DFT (TD-DFT) modeling techniques showing Light Harvesting Efficiency (LHE), Free Energy for Electron Injection (?Ginject), Excitation Energies, and Frontier Molecular Orbitals (FMOs) indicate that the series of dye comprise a more negative ?Ginject and a higher LHE value; resulting in a higher incident photon to current efficiency (IPCE).

  • Patent number: 9845271
    Abstract: A catalyst system and a process for methanol to light olefin conversion with enhanced selectivity towards propylene. The catalyst system comprises a honeycomb monolith catalyst support coated with aluminosilicate nanozeolite catalysts on the edges and inside the channels of the support structure. The aluminosilicate nanozeolite catalysts have not been pre-modified with a promoter metal. The catalyst system gives higher hydrothermal stability to the catalyst compared to randomly packed pellet catalysts and allows methanol to be converted to predominantly propylene at a low temperature, with decreased selectivity towards C2, higher olefins and paraffinic hydrocarbons.
