Abstract: A method for in-situ treatment of sediment simultaneous with microbial electricity generation is provided, comprising steps of constructing a microbial fuel cell, placing the microbial fuel cell in the sediment, forming a cell circuit, and cultivating microorganisms to generate electrical power. The method overcomes shortcomings found in the prior art and uses organics in the sediment as fuels to in-situ treat the sediment with simultaneous electricity generation. A device for implementing the method is also provided, which can be expanded in different directions as needed and is easy to maintain during long-term operation. The device has many advantages including compact structure, easy operation, low cost, high output power density, significant reduction in sediment COD, no influence on water flow, and environment-friendly.

Abstract: The present invention discloses a preparation method of carbon nanotube by decomposing the polymer with hydrotalcite as a catalyst, which belongs to the field of preparation technology of carbon nanotube (CNT). The technical solution of the present invention are as below: firstly, the hydrotalcite with the particle size at nanometer or sub-micron level is prepared, and then is added into the polymer. After the calcination process at high temperature and a treatment with acid, the nano-scale CNT can be obtained. The CNTs prepared by the method supplied in this invention not only have the advantages including high yield, uniform diameter, few structural defects, low impurity content, low cost and simple preparation process, which is suitable for large-scale industrial production, but also can solve the problem of recirculation of waste plastics and utilization of the resource.

Abstract: The invention provides an antenna for wireless devices which improves matching of the main antenna element and parasitic antenna element in the antenna. The antenna of the invention comprises a main antenna element and a parasitic antenna element, the main antenna element and the parasitic antenna element being separated from each other, a matching element is connected between the main antenna element and the parasitic antenna element, with an end of the matching element being electrically connected to a conductor strip of the main antenna element, and the other end being electrically connected to a conductor strip of the parasitic antenna element. Optimized antenna performance can be achieved by adjusting position and value of the matching element.
