Double face with high efficiency

This invention describes a process and a device for the production of double-face knitted fabrics using a double plating technique.

Adhesives from lactic acid

The invention concerns the production of special copolymers based on poly-L-lactide (PLLA) and formulations of hot-melt pressure sensitive adhesives based on them.

Retrofit polarization-maintaining in optical fibers (PM)

The invention of the University of Bonn relates to the development of a method to retrofit polarization- maintaining (PM) optical fibers in a way, that a routinated achievement of polarization to a degree better than 10-5 in extinction ratio takes place.

UHV-glass cell

The invention consists of a glass cell featuring an ultra-low birefringence (around 10–8) with an outstanding optical access due to its compact dodecagonal shape.

Poly(vinylphenothiazine)-cathodes

The presented invention describes a composite electrode for lithium-ion or redox flow batteries made of organic material with very high cycling stability.

Air-Retaining-Grids

The present invention "Air-Retaining Grids Technology" describes a new possibility for the architecture and construction of surfaces which are able to keep a layer of gas stable even under changing pressure conditions when immersed in liquid. Structured, non-wettable surfaces are used for various applications, for example as self-cleaning surfaces.

Full Inorganic Load Bearing Insulator

Scientists of the University of Duisburg-Essen developed in cooperation with the German Aerospace Center (DLR) a full inorganic insulation material with high performance qualities.

Hydrophobic Phytic Acid Conversion

The innovation presented here concerns the production and use of hydrophobic phytic acid derivatives as an environmentally friendly alternative to conventional phosphate corrosion protection pre-treatments for steel.

Leakage-reduced sliding bearing

The new, energetically optimized sliding bearing with hydrostatic support efficiently reduces the drive power of machines. The stress on the bearing is held hydrostatically by pressure generated within the bearing.

Window for high temperatures

For the monitoring of highly complex processes in closed reaction vessels, it would often be desirable to be able to observe the process and monitor it by means of optical measuring systems.

Color flop effects without interference pigments

It is an innovative, cost-effective application method for the creation of color flop effects by means of effect pigments without costly interference pigments.

Determination of the degree of curing of a coating

The method is based on the fact that the polymer network in a cured coating is denser than in a coating that is less cured. It concerns a method by which chemical cross-linking and thus suitability for further processing can be determined for a system of coatings.

NoFlameSty

Scientists from Hamm-Lippstadt University of Applied Sciences and the University of Siegen have developed halogen-free polystyrenes that intrinsically contain flame retardant components in the polymer chain.

On the trail of plasma

Plasmas are used in a wide range of technical applications, including semiconductor technology. Plasma etching and plasma-induced material deposition are used to remove functional layers in a structured manner or to selectively generate surface hardening, cleaning and activation on the target surface.

Oil float

Previous solutions or approaches to the elimination of oil spills on water surfaces consist either of actively working pumps, chemicals or materials that absorb the oil and then have to be cleaned or disposed of.

Future Display Technology

The presented technology is a two dimensional optical waveguide with very low attenuation.

Structured Yarn Coating

This invention describes a spraying process for the structured coating of a yarn with functional materials in a continuous process.
