Biomass-generated energy is booming. In most cases, it involves energy conversion in the form of thermochemical conversion, meaning that wood pellets or wood chips are converted at high temperatures into gas which is then burned in motors to generate current and heat. In the process, however, the equipment operators must deal with the formation of tars which are deposited in pipes, catalytic converters, or at the end in the gas engines. In the worst case, this can lead to an equipment breakdown and expensive repairs. Now an innovative measurement system developed by Andreas Gredinger as part of his Doctoral Degree work at the University of Stuttgart's Institute of Combustion and Power Plant Technology (IFK) may offer a solution: the unit, called “DeMiTar“, performs fast, uncomplicated, quasi-continuous measurement of tar concentrations and pinpoints the optimum working point of the system. The KIC InnoEnergy Company assisted during development, and the unit is to appear on the market shortly.

Medical studies gather a wide range of information about patients and their therapies - the more data, the more concrete is the knowledge gained. More complicated and subject to error, however, is their evaluation. The Stuttgart visualization expert Corinna Vehlow has developed a software for linking genetic information with any treatment success which may be achieved. Working at the University Clinic in Denver, she showed that her visual computer-aided method greatly simplifies the evaluation of large amounts of data. This has enabled American medical experts to derive important details concerning the successful therapy of cardiovascular diseases.

BUILD IT LIKE THE WATER SPIDER A water spider spends nearly all its life under water and needs a stable air bubble for breathing. To preserve the air bubble, the spider builds a horizontal net and places the bubble under it. In another step it reinforces the bubble on the inside with fibers. The result is a stable construction which can withstand mechanical forces like flows of water. This lightweight construction method served as the inspiration for the University of Stuttgart's Research Pavilion 2014/15 of the Institutes for Computational Design (ICD) and for Building Structures and Structural Design (ITKE). But instead of a spider, a robot first created here a soft, air-pressurized film hull and then gave it rigidity by glueing carbon fibers to it step by step on the inside. The resulting extremely light-weight composite fiber shell structure demonstrates very high efficiency in its use of materials and simultaneously opens up new design horizons for architecture.
