Let’s not make big waves

Press Release of 27.03.2019

Due to its potential to make computers faster and smartphones more efficient, spintronics is considered a promising concept for the future of electronics. In a collaboration including the Max Planck Institute for Intelligent Systems (MPI-IS) and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), a team of researchers has now successfully generated so-called spin waves much more easily and efficiently than was previously deemed possible. The researchers are presenting their results in the journal Physical Review Letters (DOI: 10.1103/PhysRevLett.122.117202).

Icy Giant Planets in the Laboratory

Press Release of 25.03.2019

Giant planets like Uranus and Neptune may contain much less free hydrogen than previously assumed. Researchers from the German Helmholtz-Zentrum Dresden-Rossendorf (HZDR) drove shock waves through two different types of plastic to reach the same temperatures and pressures present inside such planets, and observed the behavior using ultra-strong X-ray laser pulses. Unexpectedly, one of these plastics kept its crystalline structure even at the most extreme pressures reached. Since the icy giant interiors are made up of the same components as the plastic, planetary models may need to be partially reconsidered, as reported in the journal Scientific Reports (doi: 10.1038/s41598-019040782-5).

An environmental burden today, a resource for tomorrow

Press Release of 21.03.2019

The Erzgebirge is set to become a model region for the forward-looking treatment of residual materials from the mining industry. Up to €15 million will be made available from the funding program WIR! – Wandel durch Innovationen in der Region (We: Innovation for change in the region) under the auspices of the project rECOmine – Ressourcenorientierte Umwelttechnologien für das 21. Jahrhundert (rECOmine: Resource-oriented environmental technologies for the 21st century) set up by the German Federal Ministry of Education and Research. The aim is to promote new methods within the region and for the world market, by means of which tailings and metal-rich water from the mining industry can be sustainably reclaimed and the valuable residual materials can be economically extracted. The project is coordinated by the Helmholtz Institute Freiberg for Resource Technology (HIF) which is part of HZDR. TU Bergakademie Freiberg and SAXONIA Standortentwicklungs- und verwaltungsgesellschaft, a site development and management company, are involved in the running of the project, and it also enjoys the support of Wirtschaftsförderung Erzgebirge GmbH.

Reducing water consumption in mining

Press Release of 21.03.2019

Water is a vital resource on which many industries rely and which can be used more sparingly. An example is the beneficiation of mineral ores. Taking the raw material fluorite as their example, researchers at Helmholtz Institute Freiberg for Resource Technology (HIF) have now shown how water usage can be optimized. They have developed a new procedure that extends the simulation of the beneficiation process. It indicates the circumstances in which it makes sense for water to be recycled without incurring losses during ore enrichment. The consumption of fresh water can thereby be significantly reduced. This not only benefits the environment but also the mining companies, because it makes the extraction of raw materials more efficient. The researchers have presented their new procedure in the Journal of Environmental Management (DOI: 10.1016/j.jenvman.2018.11.139). HIF is part of HZDR and works in close collaboration with TU Bergakademie Freiberg.

A new spin in nano-electronics

Press Release of 25.02.2019

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 waves or so-called magnons – a promising alternative for transporting information in more compact microchips. Cooperating with international partners, they have successfully generated and controlled extremely short-wavelength spin waves. The physicists achieved this feat by harnessing a natural magnetic phenomenon, as they explain in the journal Nature Nanotechnology (DOI: 10.1038/s41565-019-0383-4).

Winzig, aber wertvoll

Press Release of 29.01.2019

Neue Technologien zur Gewinnung feinster Rohstoff-Partikel und die effiziente Wassernutzung in der Aufbereitungstechnik sind die Themen eines internationalen Expertenforums am Helmholtz-Zentrum Dresden-Rossendorf (HZDR) am 30. und 31. Januar 2019. Zu den Teilnehmern zählen Unternehmen aus der Aufbereitungsindustrie, dem Berg- und Anlagenbau sowie Vertreter europäischer Forschungseinrichtungen.

Wie der Teilchenstrahl seine Struktur bekommt

Press Release of 24.01.2019

Die Behandlung von Tumoren mit Protonen gilt als sehr vielversprechend. Bislang werden dafür allerdings große und kostspielige Anlagen benötigt, die diese geladenen Teilchen auf die nötige Energie bringen. Eine Alternative könnte die Beschleunigung per Laserkraft sein, was kompaktere Geräte ermöglichen würde. Im Profil der lasergetriebenen Protonenstrahlen kommt es jedoch immer wieder zu Unregelmäßigkeiten, was hinderlich für die medizinische Anwendung ist. Bislang ging die Forschung davon aus, dass dies auf komplizierte Plasmaprozesse im Beschleuniger zurückgeht, die schwer zu kontrollieren sind. Physiker des Helmholtz-Zentrums Dresden-Rossendorf (HZDR) haben nun eine alternative Erklärung im Fachmagazin Nature Communications (DOI: 10.1038/s41467-018-07756-z) vorgestellt.

Focused Radiation

Press Release of 21.01.2019

The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has recently begun coordinating the EU project RADIATE, in which eighteen European partners make their ion beam facilities available for measurements by guests from the scientific community and the commercial sector. In addition, the development of software programs and support for junior researchers is part of the four-year project, which is funded by the EU with approximately ten million Euros. The project launch takes place on January 22nd and 23rd in Dresden.
