An electrokinetic method for groundwater protection, soil remediation and engineering which comprises applying an electric field across an area of soil, sediment or slurry so as to generate a pH and Eh gradient and thereby promote the in situ precipitation of a stable iron-rich band. The method may be performed for the purpose of stabilisation and / or strategic dewatering / rewatering of soils, sediment and / or slurries, the improvement of the physical properties of soils and sediments for engineering purposes, the forced and directed migration of contaminated leachates, and / or electro-osmotic purging of non-polar contaminants.

The invention discloses a method for preparing a nanometer vanadium dioxide / reticular graphite-based composite electrode material. The method comprises the following steps: a. expansion and activation of graphite; b. compounding of expanded graphite and nanometer vanadium dioxide: combining the steps a. The treated graphite is evenly mixed with anhydrous ethanol and nano-vanadium dioxide; ultrasonically treated at an ultrasonic frequency of 15-35khz, then filtered, washed with anhydrous ethanol, dried, and ground into powder to obtain composite graphite; c, foamed nickel and composite graphite The graphite is mixed evenly, then polymer materials are added to mix evenly, then extruded and granulated, pressed into a desired shape, soaked in sulfuric acid with a concentration of 15-30%, washed and dried. The invention uses graphite with good electrical conductivity but low price as the matrix material, and the porous electrode material is prepared by expanding it, introducing active groups and combining with nanometer vanadium dioxide, and then compounding with the polymer material. The method of the invention is not only novel, but also short, low in cost and easy to control.

An electrode material obtained using a polyol process and a synthesis method is provided. The synthesis method includes steps of preparing a mixed solution by mixing a transition metal compound, a polyacid anionic compound and a lithium compound with a polyol solvent; and obtaining a resultant product by reacting the mixed solution in a heating apparatus. There is an advantage in that the electrode material, which has crystallinity due to a structure such as an olivine structure or a nasicon structure, can be synthesized using a polyol process at a low temperature without performing a heat treatment proces. The nanoelectrode material synthesized by the method has a high crystallinity, uniform particles, and a structure having a diameter ranging from several nanometers to several micrometers. Further, the electrode material has a high electrochemical stability.

The present invention provides a handy remote physiological signal detection system, comprising a sensing unit, a stimulation unit and a control unit. The sensing unit includes a detecting electrode, a first surface detection electrode, a second surface detection electrode and a sensing module. The sensing modules is used to detect the signals between the detection electrode and the first surface detection electrode to get an epicardial detection signal, and is also used to detect the signals between the second surface detection electrode and the first detection electrode to get a surface-ECG signal. The stimulus unit includes a stimulating electrode and a stimulus module used to provide a stimulus signal to the stimulating electrode. The control unit includes a user interface and a processing module used to convert the epicardial detection signal and the surface-ECG signal to digital signals and display the digital signals in the user interface. All systems were controlled through the remote system and are small and handy.

The invention relates to a physical therapeutic electrode slice which clamps a self-adhesive drug-loaded membrane and a preparation method thereof. The physical therapeutic electrode slice which clamps the self-adhesive drug-loaded membrane consists of an existing conductive electrode and the self-adhesive drug-loaded membrane clamped by a stripping layer, wherein, the self-adhesive drug-loaded membrane consists of a cushioning layer and a drug-release layer. The preparation method of the physical therapeutic electrode slice comprises three processes which are the preparation of gel material for the cushioning layer, the preparation of gel material for the drug-release layer and the preparation of the physical therapeutic electrode slice which clamps the self-adhesive drug-loaded membrane; besides, the gel material for the cushioning layer is essentially made from chitosan and polyvinyl alcohol, etc. and the gel material for the drug-release layer is essentially made from carbomer andalginic acid, etc. The physical therapeutic electrode slice can guarantee the stability of the environment of the drug carried by the slice and effectively reduces the competitive transfer of ion during the electric treatment process and improves the penetrating property through skin of the drug at the same time so as to improve curative effect. Besides, the physical therapeutic electrode slice which clamps the self-adhesive drug-loaded membrane has simple preparation method and great amount of drug loading, thereby being especially suitable for Western medicine and traditional Chinese medicine which are sensitive to pH value.
