- Biological fermentation process converts CO and CO2 into bioethanol and platform chemicals
- Process uses energy contained in steel plant off-gases
- Ten-year co-operation to develop and market integrated environmental solutions for the steel industry worldwide
Siemens Metals Technologies and LanzaTech have signed a ten-year co-operation agreement to develop and market integrated environmental solutions for the steel industry worldwide. The collaboration will utilize the ground-breaking fermentation technology developed by LanzaTech transforming carbon-rich off-gases generated by the steel industry into low carbon bioethanol and other platform chemicals. ...
In the focus: Printing Tiny Batteries
Novel application of 3D printing could enable the development of miniaturized medical implants, compact electronics, tiny robots, and more
3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the ...

... two engines aircraft project “Elektro E6”.
The countdown has been started for opening the gates again for the worldwide leading aviation and space event in Le Bourget, Paris from June 17th - 23rd, 2013.
EADCO & PC-Aero will present at the Paris Air Show in Hall H4 booth F-7 their new future aircraft and innovative project: ...
In the focus: Ceramic Transformer Integrates Power Supply Unit
Siemens scientists have developed new kinds of ceramics in which they can embed transformers.
The new development allows power supply transformers to be reduced to one fifth of their current size so that the normally separate switched-mode power supply units of light-emitting diodes can be integrated into the module's heat sink.
The new technology was developed in cooperation with industrial and research partners who ...
In the focus: Nanoparticle Opens the Door to Clean-Energy Alternatives
Cheaper clean-energy technologies could be made possible thanks to a new discovery.
Led by Raymond Schaak, a professor of chemistry at Penn State University, research team members have found that an important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. ...
