More than half of the world population lives in urban areas by now - rising continues. As a consequence the challenges in the fields of infrastructure, energy and environment are growing. Against this background two research projects of the University of Stuttgart seek to develop solutions for these problems.
In the first project scientists identify and evaluate instruments for achieving a sustainable energy supply and climate protection in the South African ‘City Region of Gauteng’, comprising the cities of Johannesburg, Ekurhuleni and Tshwane (incl. Pretoria). The second project is dedicated to the waste management in Ethiopians capital Addis Abeba. It is conducted in cooperation with the local University and NGOs.
The aim of the project is to reduce the greenhouse gases and to allow additional employments with acceptable working conditions. In both projects, the University of Stuttgart, the city of Stuttgart and the cities of Johannesburg, Ekurhuleni and Tshwane as well as the city of Addis Abeba are closely integrated. The official project start is June, 1st. The German Federal Ministry of Education and Research (BMBF) funds the two projects with an amount of 8.5 million euros in five years.The EnerKey project - Energy as a key element (www.enerkey.info)
Together with the Chair of Waste Management and Emissions (ISWA), the Institut for Future Energy Systems (IZES), the Federal Institute for Occupational Safety and Health (FIOSH), the Environmental Development Action in the Third World (ENDA), the Addis Ababa University (Civil Engineering Department and Regional and Local Development Studies Department) and the Addis Ababa Environmental Protection Agency (EPA) form an interdisciplinary consortium, which will be responsible for the project execution. The Association for the Promotion of Socially and Environmentally Appropriate Technology (AT-Verband) is in charge of the project’s coordination. The project partners will provide for the inclusion of local stakeholders, the implementation of pilot projects, assessment of the environmental, occupational health, social and economic impacts of the waste management measures, as well as for the training of local stakeholders and for public awareness campaigns.
The IGNIS project involves in its first stage the collection of geographic, waste and emission related data in order to establish a coherent and reliable information basis for Addis Ababa. In a following stage, decentralized plants will be setup and operated at pilot scale in Ethiopia’s capital, including plants for biowaste composting, biogasification, recycling, and improved waste collection. The Chair of Waste Management and Emissions will carry out the scientific accompaniment and evaluation of the pilot projects. One of the main tasks of the Chair of Waste Management and Emissions will be to develop mathematical models of each pilot plant based on Material Flow Analyses (MFAs), and to integrate them in a simulation programme and decision support system. Different waste management scenarios, that describe possible future developments of the waste management structure in Addis Ababa, will be simulated with the help of this programme, and their impacts on resource conservation, emissions, climate change, occupational health, and socioeconomic conditions will be assessed. "Apart from improving the quality of life of the inhabitants of the Ethiopian megacity, important insights will be gained, which will enable developing countries to reorient their waste management systems in a sustainable manner, and thereby contributing to resource conservation and climate protection“ points out Prof. Martin Kranert. It is expected that the simulation and decision support system will be applied in the future in other Megacities worldwide. Dr. Manfred Krieck from the Stuttgart Waste Management Enterprise (AWS), which supports the project, adds “we would like to contribute to the project with our practical experience in the operation of waste management systems, as well as the knowhow we have acquired through qualification of administrative personnel Stuttgart’s partner cities.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
