Researchers from the University of Strasbourg & CNRS (France), in collaboration with the University of Mons (Belgium), the Max Planck Institute for Polymer Research (Germany) and the Technische Universität Dresden (Germany), have devised a novel supramolecular strategy to introduce tunable 1D periodic potentials upon self-assembly of ad hoc organic building blocks on graphene, opening the way to the realization of hybrid organic–inorganic multilayer materials with unique electronic and optical properties. These results have been published in Nature Communications.

Bio4Comp: Molecular Motor-powered Biocomputers

Launch of a five-year, 6.1 M€ EU-Horizon 2020 project that aims to build a new type of powerful computer based on biomolecules

Crashing computers or smartphones and software security holes that allow hackers to steal millions of passwords could be prevented if it were possible to design and verify error-free software. Unfortunately, to date, this is a problem that neither engineers nor supercomputers can solve. One reason is that the computing power required to verify the correct function of a many types of software scales exponentially with the size of the program, so that processing speed, energy consumption and cooling of conventional microelectronic processors prevent current computers from verifying large programs.

The recently launched research project aims to develop a biocomputer that can overcome the two main obstacles faced by today’s supercomputers: first, they use vast amounts of electric power – so much that the development of more powerful computers is hampered primarily by limitations in the ability to cool the processors. Second, they cannot do two things at the same time. The EU now funds a project that will develop a computer based on highly efficient molecular motors that will use a fraction of the energy of existing computers, and that can tackle problems where many solutions need to be explored simultaneously.

Block Copolymer Micellization as a Protection Strategy for DNA Origami

cfaed PRESS RELEASE / 16 March 2017

Scientists from the Center for Advancing Electronics Dresden / TU Dresden and the University of Tokyo led by Dr. Thorsten-Lars Schmidt (cfaed) developed a method to protect DNA origami structures from decomposition in biological media. This protection enables future applications in nanomedicine or cell biology. Their study “Block Copolymer Micellization as a Protection Strategy for DNA Origami” was now published in Angewandte Chemie.

NaMLab and cfaed reached an important breakthrough in the development of energy-efficient electronic circuits using transistors based on germanium

Dresden, Germany, February 3, 2017
A team of scientists from the Nanoelectronic Materials Laboratory (NaMLab gGmbH) and the Cluster of Excellence Center for Advancing Electronics Dresden (cfaed) at the Dresden University of Technology have demonstrated the world-wide first transistor based on germanium that can be programmed between electron- (n) and hole- (p) conduction. Transistors based on germanium can be operated at low supply voltages and reduced power consumption, due to the low band gap compared to silicon. Additionally, the realized germanium based transistors can be reconfigured between electron and hole conduction based on the voltage applied to one of the gate electrodes. This enables to realize circuits with lower transistor count compared to state-of-the-art CMOS technologies.

Wie sich bewegliche Algen und andere „Mikroschwimmer“ in Flüssigkeiten fortbewegen, haben Experimentalphysiker der Universität des Saarlandes gemeinsam mit Dresdner Kollegen untersucht: Sie setzten Grünalgen der Gattung Chlamydomonas einer Gegenströmung aus und erfassten die Bewegungen ihrer Geißeln mittels eines hochauflösenden Tracking-Verfahrens. Hieraus wurde ein Rechenmodell abgeleitet, das exakt vorhersagt, wie sich der „Motor“ der Winzlinge unter Belastung verhält. Die Ergebnisse könnten dazu beitragen zu verstehen, wie sich künstliche Mikroroboter beispielsweise im menschlichen Organismus künftig einmal fortbewegen könnten. Die Arbeit wurde in der Zeitschrift Physical Review Letters veröffentlicht.
