Smart knitting machine
The invention describes an automated, cut-free process for manufacturing finite wire knit hoses. Individually controllable needles produce chop-free, dimensionally accurate products with reduced material loss and high process reliability.
Material Recovery From Recyclable FRP
This innovative recycling technology for CFRP and GFRP composites based on epoxy resins makes an energy-efficient, economical, and sustainable material cycle possible for the first time. High-quality fibers and polymer powders can be completely recovered and reused.

A new and improved plasma process developed by Ruhr-Universität Bochum can significantly increase energy efficiency – thus improving other possible applications such as gas or pollutant conversion.
Diagnostic tool for plasma processes
Low-temperature plasmas are used in semiconductor and medical technology and surface engineering. Production process precision and production reproducibility are a growing challenge, especially in semiconductor technology, where components are becoming increasingly smaller.
KatTex
Industrial filter bags with catalytic properties are state of the art. They consist of a multi-layer fabric, containing catalytic particle in the intermediate space. Due to this construction, there is a huge pressure lost and cost for an additional fabric layer.

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.
Separate plastic composites
KTP (Kunststofftechnik Paderborn) has developed a process for separating plastic composites and thus making them accessible for recycling. For this purpose, an intermediate layer is injection molded or co-extruded between the plastic components so that only this layer can be melted.
Recyclable polymers
The technology presented here enables the environmentally friendly production and complete recycling of polymers through targeted depolymerization. In contrast to conventional recycling processes, it allows a loss-free return to monomers and thus a true circular economy - without any loss of quality. This innovation offers companies a sustainable solution for reducing CO₂ emissions and complying with growing regulatory requirements, such as the EU Green Deal. Particularly suitable for sectors such as automotive engineering, electronics and medical technology, it makes a significant contribution to the decarbonization of the plastics industry.

Innovative materials for sustainable hydrogen production: Scientists at Ruhr-Universität Bochum have developed a high-performance NiCoFe alloy that significantly improves the efficiency and stability of alkaline water electrolysis. With low overpotentials and high resistance to reverse currents, this material offers new prospects for the decarbonization of energy-intensive industries. Thanks to versatile manufacturing processes, the alloy can be used as an anode and cathode and enables more economical hydrogen production - a decisive step towards a green energy future.
Sustainable construction/insulating material
Traditional concrete components and insulating materials often require a lot of energy to produce. A new material from the University of Bonn could offer a sustainable alternative: Plant fibres made from renewable raw materials such as miscanthus optimize the properties of concrete and insulating materials, reduce CO₂ emissions and can be grown almost anywhere. An environmentally friendly solution with great potential for the construction industry!
Hydrophobing products from renewable raw materials
An innovative insulation solution based on renewable raw materials such as miscanthus (Chinese reed) has been developed at the University of Bonn. In contrast to conventional insulating materials made from polystyrene or mineral wool, this material is impressive due to its ecological sustainability, low site requirements and high CO₂ binding. A special hydrophobization process makes the plant fibres water-repellent and therefore economically viable. This technology offers an environmentally friendly alternative with high energy efficiency and broad availability.
Organo-Metal Composites
With the aid of the invention, sulphur-free coatings can easily be produced on base metal surfaces. This makes functionalized surfaces accessible, e.g. for sensors etc.

The present invention relates to polymers from renewable raw materials, as well as monomeric precursors for the production of furan-containing polymers and a production process of both the polymers and the precursors. The 5-HMF derivatives serve as monomers for, among others, biodegradable polyesters, polyamides, polyimines and polyurethanes.
Amipysurf
An Invention for prevention of bacterial infection by applying an antimicrobial latex for a surface coating that is mechanically stabilized by chemical or photochemical crosslinking
Quantum Dot Arrays
Nanostructures are suitable for the fabrication of optoelectronic devices, but their fabrication is costly. Their utility, however, is immense: mode profiles can be created in a direct way, for example, to "attract" lasers or to adjust densities for single quantum dot applications such as single photon sources.
Hydrophobic Phytic Acid Conversion

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
Halogen-free polystyrenes that contain flame-retardant components in the polymer chain. These styrene copolymers can be produced synthetically in a batch process using inexpensive raw materials and are characterized by self-extinguishing fire behaviour without the addition of flame retardants. The resulting polymers are completely colorless and odorless and can be extruded and/or foamed using conventional processing methods. If necessary, the fire behaviour can be further optimized by adding flame retardants, depending on the application.

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.
