Innovative automobile batteries are getting ready to leave the research labs to become components of modern vehicles. During the worldwide introduction of lithium-ion batteries in hybrid cars, the European automotive industry is preparing to take over global leadership.
New mild-hybrid concepts facilitate significant CO2 savings at a perspectively very favorable cost/benefit ratio. Even the well-established lead acid starter battery is undergoing massive innovation to meet the challenges of growing electrical facilitation, energy management, and stop/start functionality as a low-cost commodity.
In Europe, plug-in hybrids and battery-driven vehicles are increasingly viewed as interesting options to substitute crude oil as a primary energy source and at the same time, reduce CO2 emission.
Electro-mobility brings about challenges for electric power grid regulation, and also offers the opportunity of utilizing millions of traction batteries as a buffer for the stabilization of the grid, especially for the increasing share of renewable and fluctuating power generators as well.
Current developments, trends and perspectives will be presented during a 2-Day Technical Conference taking place on January 20th to 21st 2009, in the Haus der Technik in Essen. For the first time in the German-speaking region, this conference offers a forum to the developers of batteries, battery material, energy management and storage system solutions. An additional emphasis is also placed on networking these activities with the electric utilities.This symposium will present and document the state-of-the-art in all fields found in the value-added chain, and at the same time, facilitate communication between industries and economic areas not interacting at this time. Renowned international scientists and engineers will be attending the conference in Essen, to discuss the technical innovation and visionary possibilities of utilizating this novel battery concept in vehicles and other applications.
Expert meeting “Health Business Connect” will connect international medical technology companies

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...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
