The use of silicon as anode material promises high theoretical energy density in lithium-ion batteries. However, the volume of a silicon-based anode may increase substantially during lithiation. In order to solve this problem, scientists at the Institute of Photovoltaics (ipv), University of Stuttgart, now succeeded in developing a method for producing micro-stabilized and porous silicon anodes by means of laser irradiation. The battery electrodes related to this invention offer a high potential for lithiation and at the same time improved mechanical stability. Due to a large active surface they provide high energy density. They can be used for the production of mechanically flexible batteries.

The invention presented here relates to a procedure and device for the identification of borderlines of hypersurfaces from data matrices.
Scientists of the University of Duisburg-Essen developed in cooperation with the German Aerospace Center (DLR) a full inorganic insulation material with high performance qualities. The material exhibits extraordinary heat-insulating and load-carrying properties. It combines the benefits of conventional inorganic building material like compressive strength and the ability to be poured into all kind of durable moulds with the advantage of being heat-insulating. The latter makes it perfect with regards to energy saving aspects. The designated properties are dependent on the ratio of matrix-to insulation-material. It’s very low weight in combination with its compression strength and its flame-retardant properties makes it a potential construction material even for applications with high demands.
The superlight and superinsulating material could be used in cars, trains and any other kind of vehicles. Even aerospace applications are imaginable. By its heat resistance, the material enables the passive isolation of load bearing areas in buildings as well as passive insulation in areas where high temperatures occur like exhaust systems or furnaces. In addition, the material isolates not only thermally but also acoustically. High efficient heat pumps, new kinds of filters for clean air inside cars, trains and airplanes are just some examples of applications.
These findings can potentially be used in developing efficient and environmentally-conscious coagulants for water treatment. The findings were presented on May…
