Stable and ordered single molecule layers on silicon through self-assembly
An interdisciplinary team of researchers has succeeded in depositing nitrogen-containing organic molecules as a highly ordered layer on silicon. This opens up new perspectives for the development of more powerful semiconductor materials, which can be used, for example, in computers, photovoltaics ...
A design principle for the self-assembly of functionalized molecules devised
Using machine learning methods, researchers at TU Graz can predict the structure formation of functionalized molecules at the interfaces of hybrid materials. Now they have also succeeded in looking behind the driving forces of this structure formation. The production of nanomaterials involves ...
Nanostructures for electronics, catalysis, medicine
A team from Helmholtz-Zentrum Berlin (HZB) used cryo electron microscopy to detect regular, two-dimensional structures in the form of Pascal triangles in a shock frozen protein material. The samples have been synthesized by a Chinese research group. The method of cryo electron microscopy has the ...
New active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots
A joint paper by Kazan Federal University, Boreskov Institute of Catalysis, and Russian Oil and Gas University was published in Chemistry - A European Journal. The team produced and studied new active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots ...
Self-assembly of responsive photonic biobased materials in liquid marbles
A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid--so-called liquid ...
How to control individual components of self-assembling molecular structures
In the development of autonomous systems and materials, self-assembling molecular structures controlled by chemical reaction networks are increasingly important. However, there is a lack of simple external mechanisms that ensure that the components of these reaction networks can be activated in a ...
Researchers control the size of molecular superstructures on surfaces
Most technical functional units are built bit by bit according to a well-designed construction plan. The components are sequentially put in place by humans or machines. Life, however, is based on a different principle. It starts bottom-up with molecular self-assembly. The crystallization of sugar ...
The electrical charge is what makes the difference
A new membrane developed at the Helmholtz-Zentrum Geesthacht (HZG) separates small dye particles or drug substances not only by size but also by their electrical charge. This additional function enables organic molecules with lateral dimensions of one to two nanometres to be such high-efficiently ...
New perspectives for designing materials and transferring information molecularly
Knots are all around us: in computer cables, headphones and wires. But, although they can be a nuisance, they're also very useful when it comes to tying up your laces or when you go sailing. In maths, there are no less than six billion different potential knots, but what about knots in chemistry? ...
Verner Håkonsen works with cubes so tiny that nearly 5 billion of them could fit on a pinhead. He cooks up the cubes in the Norwegian University of Science and Technology's (NTNU) NanoLab, in a weird-looking glass flask with three necks on the top using a mixture of chemicals and special ...
