Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.

Rapid controlled self-assembly makes DNA ideal for building nanostructures. A problem using hybridized intermediates in hierarchic assembly is their thermodynamic lability. We demonstrate a click-fixation technology by which robust hexagonal DNA modules can be made. This principle is applicable to a wide variety of DNA nanoconstructs.

BACKGROUND The tissue growth necessary to achieve a complete or partial restitution ad integrum as a result of injury to soft tissue and/or hard times in reptiles is variable and often needs long time in relation to the species, to the habitat and to their intrinsic physiological characteristics. The purpose of this work was to see if the tissue optimization (TO) treatment with radio electric a...

The 10 Bologna Conference on “Magnetic Resonance in Porous Media” was among the impressive events which, dedicated to the 600 anniversary of Leipzig University in December 2009, attracted colleagues from all over the world. The conference excursion took the participants to Ferropolis, a place north of Leipzig, equipped with impressive remainings of an old mining site, including huge conveyer br...

Lock-in thermography measurements were performed to reveal heat source distribution induced by the unidirectional spin-wave conveyer effect (USHCE) of magnetostatic surface spin waves. When waves are excited in an yttrium iron garnet slab, lock-in images show spatially biased sharp and complicated heating patterns, indicating importance edge dynamics for USHCE. The accessibility local emission ...
