Dissymmetric particles also called Janus particles of micron or submicron size and methods of synthesis of Janus particles by bipolar electrochemistry, based on substrates of isotropic or anisotropic shape. The particles include an electrically conductive substrate having at least a chemically and / or physically modified part by deposit of a layer of electrochemically depositable material, and a non-modified part. The particles are of isotropic shape, and the layer of electrochemically depositable material has a specific shape delimited by a precise contour.

The present invention provides a terminal assembly, and storage batteries comprising a terminal assembly, wherein the terminal assembly comprises a conductive cup-shaped member comprising a terminal wall in electric communication with a terminal of the electrochemical cell when the terminal wall is in contact with the terminal; a sidewall; and a rim separated from the terminal wall by the sidewall; and a bipolar endplate having first and second surfaces coplanar with the terminal wall and joining to the rim at the first surface, the joining enabling bi-directional uniform current flow through the cup-shaped member between the terminal and the endplate when the terminal wall is in contact with the terminal, the endplate having an electrochemically active region comprising a first surface area enclosed by the rim and a remaining second surface area outside an outer periphery of the rim, the first and second surface areas being substantially equal.

The invention discloses a dry type bipolar electrochemiluminescent chip and its application in immunoassay. The chip includes a bottom plate, an electrode sheet, a detection sheet, a bonding sheet and a sample adding sheet; the electrode sheet includes an integrated bipolar Electrodes and driving electrodes, the integrated bipolar electrode is designed with two anodes distributed in a Y shape, one of the bipolar electrode anodes is placed corresponding to the driving electrode, and is called the detection anode; the electrode sheet is placed in the reporting channel folded between the support channel; the detection sheet is designed with Y-shaped hydrophilic channels; the detection sheet is stacked on the electrode sheet, so that the hydrophilic channel overlaps with the anode of the integrated bipolar electrode; The hydrophilic channel overlapping with the detection anode on the electrode sheet is used as the detection area. This patent is the first invention of a dry immune CBP-ECL chip, which overcomes the shortcomings of the existing immune CBP-ECL chip that is cumbersome to operate and requires multi-step addition of solutions by integrating the reaction reagent components on the chip.

Bipolar electrochemistry (BPE) concepts are used to provide a single-step and controllable process for simultaneously exfoliating a graphite source and depositing both graphene oxide and reduced graphene oxide layers on conductive substrates. A bipolar electrochemical cell can be used for a three-in-one deposition and can include two wired pieces of graphite to monitor the amount of current that passes through the bipolar electrode.

The invention discloses a method for rapidly preparing an anodized titanium nanotube array film. The steps are as follows: folding the polished titanium sheet into a "U" shape, inserting the first end of the titanium sheet into the first electrolytic cell, and The second end of the first electrolytic cell is inserted into the second electrolytic cell, the first electrolytic cell is provided with a first graphite plate electrode, the second electrolytic cell is provided with a second graphite plate electrode, and the two graphite plate electrodes are respectively connected to the first end and the second end of the titanium sheet Parallel and equal distance, energized for constant voltage anodizing treatment. In the present invention, under the condition of closed bipolar electrochemical anodic oxidation, the titanium sheet is rapidly, uniformly and stably formed into a regular titanium oxide nanotube array film in a fluorine-containing electrolyte, and the growth rate of the nanotube can reach 2.0 μm min ‑1 Above, this method can control the growth rate of the oxide film by changing the ammonium fluoride concentration of the electrolyte in the two electrolytic cells and the size of the titanium sheet area in the cathodic electrolytic cell, and the oxide film grown under high current density is not easy Breakdown occurs.
