New Form of Microscopy Developed

Breakthrough in nanooptics

28-Apr-2020

The duration of their snapshot relates to one second as one second relates to the age of the universe: In a joint collaboration with Australian Scientist Tim Davis and the Group around Harald Gießen (University of Stuttgart), Physicists from CENIDEhave developed ultrafast vector microscopy as a ...

Artificial solid fog material creates pleasant laser light

Extremely porous material made of "white graphene" for new laser light applications

20-Mar-2020

With a porosity of 99.99 %, it consists practically only of air, making it one of the lightest materials in the world: Aerobornitride is the name of the material developed by an international research team led by Kiel University. The scientists assume that they have thereby created a central ...

Imprinted Color Patterns

Azopolymer material allows light-assisted imprinting of nanostructures for structurally colored surfaces

17-Jan-2020

Structural colors appear because the imprinted pattern on a surface changes the wavelengths of light. Chinese scientists have introduced an azopolymer that allows the imprinting of nanopatterns in a novel room-temperature lithographic process. A key aspect of the technique is the light-induced ...

Pretty with a twist

Complex, porous, chiral nano-patterns arise from a simple linear building blocks

17-Jan-2020

Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular ...

How to induce magnetism in graphene

Elusive molecule predicted in the 1970s synthesized

11-Dec-2019

Graphene, a two-dimensional structure made of carbon, is a material with excellent mechani-cal, electronic and optical properties. However, it did not seem suitable for magnetic applica-tions. Together with international partners, Empa researchers have now succeeded in synthesiz-ing a unique ...

Electron correlations in carbon nanostructures

Behaviour of electrons in graphene nanoribbons elucidated

05-Dec-2019

New materials are needed to further reduce the size of electronic components and thus make devices such as laptops and smartphones faster and more efficient. Tiny nanostructures of the novel material graphene are promising in this respect. Graphene consists of a single layer of carbon atoms and, ...

Researchers develop new 3D printing for the direct production of nanostructures

14-Nov-2019

A team from Graz University of Technology succeeded in using the FEBID method to produce complex 3D-printed nano-components for the first time without additional support structures. In the nanometer range, complex, free-standing 3D architectures are very difficult to produce in a single step due ...

Super-strong magnetic supercrystals can assemble themselves

29-Oct-2019

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 ...

Analytical tool designs corkscrew-shaped nano-antennae

Save time using maths

26-Aug-2019

For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology. The nanostructures ...
