When damaged ropes change color

Wafer-thin layers with great effect

07-Jan-2021

High-performance fibres that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them. For example, safety ropes used by fire brigades or suspension ropes for heavy loads on construction sites. ...

Coating plastics by porous nanofilm

New method for creating metal-organic framework thin films

11-Nov-2020

A research team has developed a new method for creating metal-organic framework (MOF) thin films that can be applied to sensors and electric devices. Like sponges, porous materials contain pores. The pore size affects the property of the material. For example, small pores create more absorbent ...

Nano coatings with many functions

Materials scientists synthesize nanoscale gradient copolymers with contradictory properties for the first time

05-Nov-2020

Materials that simultaneously have contrasting properties – for example, they are soft on the one hand and hard on the other, the transition is gradual - could enable completely new applications like gradual anti-reflective lenses. In nature, such merging properties are indeed common, for example ...

Graphite instead of gold: Thin layers for better hydrogen cars

Innovative coating for bipolar plates in fuel cells

02-Oct-2020

Electric cars which can be filled up within five minutes, reach ranges like a diesel and yet drive "cleanly": This is already being achieved by hydrogen fuel cell vehicles today. However, so far they are still rare and expensive. Apart from efficiency problems, this is due, among other things, to ...

Chemist developed a new type of one-molecule thick water-repellent film

2D organic nanofilms can be used to create protective hydrophobic or anti-corrosion coatings for organic electronics or to develop molecular filters

14-Sep-2020

A chemist from RUDN University together with colleagues created a new type of two-dimensional nanofilm from an organic material called calixarene. The invention can be used as a protective coating in electronics and as a part of molecular filters. They also suggested a way of increasing the ...

Painting with crystals

12-Aug-2020

Semiconductors made of organic materials, e.g. for light-emitting diodes (OLEDs) and solar cells, could replace or supplement silicon-based electronics in the future. The efficiency of such devices depends crucially on the quality of thin layers of such organic semiconductors. These layers are ...

Special coating protects steel from hydrogen ‘attack’

Almost no evidence of brittleness

29-Jul-2020

Regeneratively produced hydrogen is an ideal energy carrier, which will be used in future applications as fuel cells and cars and will supplement natural gas as an energy source. But atomic hydrogen often induces brittle behavior in metals at high temperatures. Lukas Gröner of the Fraunhofer IWM, ...

OptoPolymer now part of Berghof Fluoroplastics

In doing so, Berghof Fluoroplastics will expand its portfolio to include optical coatings with Barium sulfate

22-Jul-2020

Photonics, the science and technology of light, is one of the most important growth and future industries - and this positive trend will even strengthen in the coming years. It's not a miracle that the European Commission has already recognized photonics in 2009 as one of the five "Key Enabling ...

New chemistry for ultra-thin gas sensors

New process for zinc oxide layers that can be used for nitrogen oxide sensors as well as protection layer on plastic

02-Jul-2020

The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which employs typically chemical compounds, or simply precursors, which ...
