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.

Maintaining polarization in optical fibers (PoF)

Apparatus and method for precisely maintaining the linear polarization of light at the output of an optical fiber

UHV-glass cell

The invention consists of a glass cell characterized by an outstanding value of birefringence (around 10–8) with an extensive optical access due to its dodecagonal shape.


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


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.

Ligand-free production of gold nanoparticles

The invention related to a process for the preparation of ligand-free gold nanoparticles (Au-NP).

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.

Overlap Fix

Due to the limited needle shifting in state of the art weaving systems, current textile products present many limitations regarding their effectiveness and lifetime.

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.


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.
