  • Publication number: 20240096631
    Abstract: The present disclosure relates to a bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursors, and ultra high purity versions thereof, methods of making, and methods of using these bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursors in a vapor deposition process. One aspect of the disclosure relates to an ultrahigh purity bridging asymmetric haloalkynyl dicobalt hexacarbonyl precursor of the formula Co2(CO)6(R3C?CR4), where R3 and R4 are different organic moieties and R4 is more electronegative or more electron withdrawing compared to R3.

  • Patent number: 7456183
    Abstract: Compounds having the general structure I are provided. X and Y are independently selected from the group consisting of CH2, N, NR9, C?O, C?S, S?O, SO2, S, O, (CR6R7)n, C(?O)—(CR6R7)n, and C(?S)—(CR6R7)n, where n is 1, 2, or 3. W is selected from the group consisting of (formula I) and L is selected from the group consisting of N, O, S?O, SO2, C(O), NC(O), NC(S), OC(O), OC(S), C(NR10), C(NOR10), and a covalent bond. Z1, Z2, and Z3 are independently selected from the group consisting of substituted carbon and nitrogen. Compounds of formula I are agonists of the melanocortin-4 receptor (“MC-4r2) and therefore may have useful properties for controlling diseases related to MC-4r action in humans, such as obesity and type II diabetes.

  • Patent number: 6245148
    Abstract: The present invention relates to a SOG (Spin-On-Glass) dispensing system and its controlling sequences and, more particularly, to a SOG dispensing system allowing for continuous production and its controlling sequences According to the present invention, a buffer tank, whose wall is set a plurality of level sensors at different level heights, is connected between a source tank with a SOG bottle inside and a coating unit of prior art and then SOG is supplied for a time interval from the source tank into the buffer tank by control signals from these level sensors. Besides, the buffer tank is surrounded with a cooling unit to provide a low temperature enviroment allowing for prolonging life time of SOG and preventing organic solvent inside SOG from evaporating and then crystallizing to form contamination particles at wall of the SOG dispensing system.
