Recycle high-tech waste biologically

Innovative biotechnological process extracts gallium from industrial wastewater

18-Mar-2021

Gallium is a rare metal, but it is widely used in the high-tech industry. This extreme contrast makes recycling indispensable. However, current recycling processes are costly and chemically polluted. Biotechnological approaches, therefore, rely on peptides, as they are able to bind metallic ...

A new spin in nano-electronics

Researchers succeed in controlling extremely short-wavelength spin waves

27-Feb-2019

In recent years, electronic data processing has been evolving in one direction only: The industry has downsized its components to the nanometer range. But this process is now reaching its physical limits. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are therefore exploring spin ...

Three magnetic states for each hole

06-Feb-2017

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered ...

Random Access Memory on a Low Energy Diet

Researchers develop basis for a novel memory chip

05-Jan-2017

Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers from Dresden and Basel have now managed to lay the foundation for a new memory chip concept. It has the potential to ...

A highway for spin waves

Researchers in Dresden develop process for controlling innovative information media

04-Feb-2016

The success story of information processing by way of moving electrons is slowly coming to an end. The trend towards more and more compact chips constitutes a major challenge for manufacturers, since the increasing miniaturization creates partly unsolvable physical problems. This is why magnetic ...

The Puzzle of the Origin of Elements in the Universe

18-Dec-2015

The LUNA experiment at the INFN Gran Sasso National Laboratory in Italy has observed a rare nuclear reaction that occurs in giant red stars, a type of star in which our sun will also evolve. This is the first direct observation of sodium production in these stars, one of the nuclear reactions ...

Nanomagnets: Creating order out of chaos

Physicists engrave nanoscale magnets directly into layer of material

25-Nov-2015

Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have proposed the use of ion beams for their fabrication. An ultra-fine beam consisting of around 10 neon ...

Nano-Dunes with the Ion Beam

10-Sep-2015

In their astounding method, the researchers use ion beams, which are fast, electrically charged atoms. They direct a broad beam of noble gas ions onto a gallium arsenide wafer, which, for example, is used in producing high-speed and high-frequency transistors, photocells or light-emitting diodes. ...
