Microfluidic devices having a reduced number of input and output connections

A system and method for reducing the number of input/output connections required to connect a microfluidic substrate to an external controller for controlling the substrate. In one example, a microfluidic processing device is fabricated on a substrate having a plurality of N independently controllable components, (e.g., a resistive heating elements) each having at least two terminals. The substrate includes a plurality of input/output contacts for connecting the substrate to an external controller, and a plurality of leads for connecting the contacts to the terminals of the components. The leads are arranged to allow the external controller to supply control signals to the terminals of the components via the contacts using substantially fewer contacts than the total number of component terminals. For example, in one embodiment, each lead connects a corresponding contact to a plurality of terminals to allow the controller to supply to signals to the terminals without requiring a separate contact for each terminal. However, to assure that the components can each be controlled independently of the others, the leads are also arranged so that each component's terminals are connected to a unique combination of contacts. Thus, the external controller can activate a selected component by supplying control signals to the combination of contacts uniquely associated with that component.

Method for manufacturing alkylate oil with composite ionic liquid used as catalyst

The present invention pertains to a method for manufacturing alkylate oil using a composite ionic liquid as catalyst. A mixture of isobutane and C4 olefins is used as the raw material, and a composite ionic liquid is used as catalyst to carry out an alkylation reaction. The alkane / olefin ratio in the raw material is higher than 1:1. In the composition of the aforementioned composite ionic liquid catalyst, the cations come from a hydrohalide of an alkyl-containing amine or pyridine, while the anions are composite coordinate anions coming from two or more metal compounds. One of the metal compounds is an aluminum compound, while other metal compounds are compounds of Group IB and Group IIB elements of the Periodic Table and the transition metals. The present invention also provides a design of static mixer reaction apparatus that can realize the aforementioned manufacturing method. The method of the present invention increases the selectivity of the alkylation reaction to give the alkylation product a relatively high octane number and further increase the product yield. Also, the manufacturing operation is simplified, and the cost can be reduced. This method is an environmentally friendly method that will not pollute the environment.
