摘要:
Methods and apparatus for facilitating the synthesis of compounds in a nonflow-through device are presented. Application of the nonflow-through methods and microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the introduction of a pressurized gas through a tangential slit into a vortex reactor of the nonflow-through device, while one or more liquids are delivered to the reaction chamber through the same or different inlet ports. The introduction of the pressurized gas produces a cyclonic motion of the mixture within the reactor. Such a mechanism may be used to facilitate the evaporation of various liquids within the reactor at lower temperatures, thus reducing the production of unwanted byproducts that are associated with the use of high temperatures. In addition, thorough mixing of various liquids may be effected rapidly while allowing chemical reactions to take place efficiently within the vortex reactor.

The invention relates to a process for utilizing the heavy liquid fractions resulting from oil refining, by combustion in a fluidized-bed chemical looping process. The process according to the invention is used to produce energy by completely oxidizing the heavy liquid feedstocks, while allowing direct capture of the CO 2 emitted in the combustion flue gases. The process according to the invention also enables a syngas to be produced.
摘要:
A manufacturing method of a support unit for a microfluidic system, comprising: forming a first adhesive layer on a surface of a first support; and laying a hollow filament on a surface of the first adhesive layer by applying a load and ultrasonic vibration or by applying a load and emitting a laser beam.

The present invention provides a supporting unit of microfluid system having a smaller restriction on the number of the steps and capacity of the reaction and analysis that can be produced easily, and a microfluid-system supporting unit allowing mounting of complicated fluid circuits densely. The present invention relates to a microfluid-system supporting unit, comprising a first supporting plate and at least one hollow filament constituting the channel of the microfluid system, wherein the hollow filament is placed on the first supporting plate in any shape and a particular internal region of the hollow filament has a function.
摘要:
An apparatus and method for measuring a range of small volumes of fluids to a high degree of precision, said apparatus including: a) a single reaction chamber (20); b) a piston (30) operable within said chamber to selectively and precisely vary the internal volume of said chamber; c) a first inlet (41) to said chamber in communication with one or more fluid sources of which a portion of a first fluid of said one or more fluids is adapted to be drawn into said chamber; d) at least one further inlet (43) including a second inlet to said chamber in communication with one or more fluid sources of which a portion of a second fluid of said one or more fluids is adapted to be drawn into said chamber; and e) a sealable outlet (45), wherein said piston is adapted to progressive draw said portion of a second fluid into said chamber until either accurare metering of a volume of said first or second portion of fluid is achived or a reaction involving said first and second portions in said chamber (such as a titration reaction) is completed.
