New 2D-materials tailored by self organization and photopolymerisation
An international research team led by members from the Technical University of Munich, the Deutsches Museum, the Linköping University has developed a method to manufacture two-dimensional polymers with the thickness of a single molecule. The polymers are formed on a surface by the action of ...
The groove of the self-organized active nematic ribbon
Nematic materials, such as the liquid crystals in our displays, contain molecules that align themselves in parallel. When they are constructed from microtubules and kinesins, materials found in our cells, they become active and move and deform without the supply of energy from the outside. In a ...
Innovative path to novel materials with adaptive electrical and optical properties
A team of researchers has used X-rays from DESY's research light source PETRA III to explore the amazingly diverse self-organisation of liquid crystals in nanometre-sized pores. The study, led by Patrick Huber from the Hamburg University of Technology (TUHH), shows how liquid crystals arrange ...
The tiny rings that chemists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) create in the laboratory are as small as a bacterium. Self-organized, individual polymer chains form the flexible structures that can even squeeze themselves through cell membranes. ...
Scientists show new mechanism of self-organization of living matter
Cells and microorganisms produce and consume all sorts of chemicals, from nutrients to signaling molecules. The same happens at the nanoscale inside cells themselves, where enzymes catalyze the production and consumption of the chemicals needed for life. In new work published in Physical Review ...
They look like interlocking egg cups, but a hen's egg is 100,000 times as thick as one of the miniature cups: Scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have made polymers to form themselves into tiny cups on their own. They could, for example, ...
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In ...
A team at the HZB has discovered a new method for producing efficient contact layers in perovskite solar cells. It is based on molecules that organise themselves into a monolayer. In recent years, solar cells based on metal halide perovskites have achieved an exceptional increase in efficiency. ...
Universal pH regulated assembly of DNA nanostructures
DNA, the carrier of genetic information, has become established as a highly useful building material in nanotechnology. One requirement in many applications is the controlled, switchable assembly of nanostructures. Scientists have now introduced a new strategy for control through altering pH ...
Together with colleagues from the USA, scientists from the University of Bonn and the research institute Caesar in Bonn have used nanostructures to construct a tiny machine that constitutes a rotatory motor and can move in a specific direction. The researchers used circular structures from ...
