Textilbewehrter Beton – Grundlagen für die Entwicklung einer neuartigen Technologie / SFB 532
Zementgebundener Beton, mengenmäßig der bedeutendste Werkstoff des Bauwesens, bietet hinsichtlich konstruktiver Gestaltung und Herstellungstechnik ein breites Feld von Möglichkeiten und ist zur Übertragung von Druckkräften der bei weitem preiswerteste Baustoff. Wegen der geringen Zugfestigkeit wird für die bei der Rissbildung freigesetzten Zugkräfte in der Regel eine Stahlbewehrung angeordnet. Im Sonderforschungsbereich 532 werden die Grundlagen des Verbundwerkstoffes „Textilbewehrter Beton“ erforscht, in d
Mathematische Modellierung, Simulation und Verifikation inmaterialorientierten Prozessen und intelligenten Systemen / SFB 438
Die Entwicklung neuer Materialien und materialabhängiger Systemkomponenten mit spezifischen, anwendungsangepassten Eigenschaften hat in den vergangenen Jahren viele technologische Einsatzmöglichkeiten eröffnet. Dabei kommen so verschiedenartige Materialien wie Formgedächtnis-Legierungen, polymere Fluide und Materialien mit spezifischen elektrischen und magnetischen Eigenschaften in Anwendungsbereichen zum Einsatz, die sich von der Automobilindustrie über Mikroelektronik, Robotik und Verfahrenstechnik bis hi
Distant Star Bursts provide key to the origin of Galaxies
Revealing images produced by one of the world’s most sophisticated telescopes are enabling a team of Edinburgh astronomers to see clearly for the first time how distant galaxies were formed 12 billion years ago. Scientists from the UK Astronomy Technology Centre (UK ATC) and the University of Edinburgh have been targeting the biggest and most distant galaxies in the Universe with the world’s most sensitive submillimetre camera, SCUBA. The camera, built in Edinburgh, is operated on the James Clerk Ma
Ancient Relatives of Algae Yield New Insights into Role of CO<sub>2</sub> in Earth’s Early Atmosphere
Awareness of the global warming effects of carbon dioxide (CO2) is relatively recent, but the greenhouse gas has been playing a critical role in warming our planet for billions of years, according to University of Maryland geologist Jay Kaufman and Virginia Polytechnic Institute geologist Shuhai Xiao.
Their results, which provide the best evidence to date of the age of the Calvin cycle—the photosynthetic cycle by which plants convert light energy and CO2 into cellular tissue—will be publishe
Contaminated water from abandoned mines threatens colorado ski areas, say Colorado U. researchers
The ability of several of Colorado’s prime ski areas to respond to winter drought is threatened by acidic runoff from abandoned mines, according to researchers at the University of Colorado at Boulder and the Northwest Colorado Council of Governments.
Contamination known as acid-rock drainage enters waterways, such as Summit County’s Snake River, that are used for making artificial snow. When the snow melts, the water can run into streams not previously polluted, further spreading
Countries find common ground to protect world’s rarest gorilla
The Ministers of the environment from Nigeria and Cameroon have established an agreement to protect the Cross River gorilla, the world’s rarest subspecies of gorilla that totals a mere 280 individuals throughout its entire range, according to the Wildlife Conservation Society (WCS). The Cross River gorilla is only found in Cross River State, Nigeria and western Cameroon and is highly threatened from poaching and habitat fragmentation and loss.
