Abstract: A parameter calculation assistance method and system include: S1, receiving three-dimensional test data-set; S2, when a device model of an integrated circuit device is fitted, drawing a fitted curve regarding voltage-current-capacitance in a form of data point bit in a visualization interface according to a test data group; and S3, in response to a user-defined selection rule editor being configured in the visualization interface, inputting a selection operation algorithm required for parameter selection on the fitted curve within visualization interface; and based on selection operation algorithm being configured in the user-defined selection rule editor, when a selection operation of the fitted curve in the visualization interface is performed, selecting the data point bit adapted to a selection operation rule in a selection region for calculating a parameter of the device model.

Abstract: An electrode deionizer and method remove polarized molecules of an ionic cluster in a fluid. In another aspect, electrophoresis and dielectrophoresis forces are used between electrodes to move a polarized molecular cluster in an electric field, which are then trapped in an activated-carbon on an anode. A further aspect uses dielectrophoresis to reduce the size of polarized molecules of an ionic cluster in a fluid. Yet another aspect of the present apparatus and method employ RF power in addition to DC power.

Abstract: A plasma activated biochar filter is provided. In another aspect, Fluorine-based reactive gas is used in a plasma reactor to activate biochar. A further aspect employs a substrate flocked with plasma activated biochar. Yet another aspect employs plasma activated and fluorinated biochar on a porous substrate to act as an oil-fluid separating filter.

Abstract: An electrode apparatus and method remove a polarized molecule in a fluid. In another aspect, a non-uniform electric field is created between an anode and a cathode, the fluid flows within a gap between the cathode and the anode, and the polarized molecule is driven by an electrostatic force to and adsorbed on the anode without experiencing a chemical reaction.
