Consumer demand for lighter, more powerful handheld devices such as laptop computers and mobile phones is growing year on year. The EUREKA project 3D STRUCTURES has addressed one of the key requirements – cheaper and lighter batteries that last longer.
French lead partner SCPS (Societé de Conseil et de Prospective Scientifique S.A.) has developed a new kind of conductive metallic foam capable of replacing heavy metallic parts. A cylindrical block of foam is immersed in an aqueous solution thereby coating all the pores with conductive material. The cylinder can be peeled forming a strip of foam which can then be electroplated. Next, the plastic foam is burnt out, leaving the metallic shape, i.e. the 3D structure that can be used as electrodes, the charge-collecting part in batteries for applications in computers and cars.
For example, a copper foam will be used in heat exchangers, where it can replace heavy and cumbersome fins, making a more efficient and compact unit. It will also be utilised in the next generation of hybrid cars with 36V batteries, where more power will be needed for acceleration and deceleration.

Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
