  • Patent number: 9811097
    Abstract: A system and computer program product are provided for controlling liquid-cooled electronics, which includes measuring a first set point temperature, Ta, wherein the Ta is based on a dew point temperature, Tdp of a computer room. A second set point temperature, Tb, is measured, wherein the Tb is based on a facility chilled liquid inlet temperature, Tci, and a rack power, Prack, of an electronics rack. A Modular Cooling Unit (MCU) set point temperature, Tsp, is selected. The Tsp is the higher value of said Ta and said Tb. Responsive to the selected Tsp, a control valve is regulated. The control valve controls a flow of liquid that passes through a heat exchanger.

  • Patent number: 8709892
    Abstract: A method for fabricating a flash memory device where the flash memory device includes a substantially uniform size and spatial distribution of nanoparticles on a tunnel oxide layer to form a floating gate. The flash memory device may be fabricated by defining active areas in a substrate and forming an oxide layer on the substrate. A self-assembled protein lattice may be formed on top of the oxide layer where the self-assembled protein lattice includes a plurality of molecular chaperones. The cavities of the chaperones may provide confined spaces where nanocrystals can be trapped thereby forming an ordered nanocrystal lattice. A substantially uniform distribution of nanocrystals may be formed on the oxide layer upon removal of the self-assembled protein lattice such as through high temperature annealing.

  • Patent number: 7427497
    Abstract: Disclosed herein is a microfluidics device that can be used to prepare natural products and their analogs. The device comprises the enzymes of a biosynthetic pathway immobilized thereon and a means for sequentially directing a starting material and each ensuing reaction product to the enzymes of the biosynthetic pathway in the order corresponding to the steps of the biosynthetic pathway. The device can thus be used to prepare the natural product using the natural starting material of the biosynthetic pathway or analogs of the natural product using an unnatural starting material. Alternatively, artificial pathways can be created by immobilizing an appropriate selection of enzymes on the device in an order whereby each subsequent enzyme can catalyze a reaction with the product of the prior enzyme. Novel chemical entities can be prepared from these artificial pathways.
