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.
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.
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.
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.
Efficient Hydrogen Production
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.
Hydrogen free Water2Ammonia
An innovative electrochemical process is revolutionizing sustainable ammonia synthesis: using a palladium membrane as a selective hydrogen bridge, the technology enables an efficient LiNRR reaction with water as the hydrogen source. Compared to conventional methods, the system increases NH₃ production by 200% and offers an environmentally friendly alternative to the energy-intensive Haber-Bosch process. Ideal for applications in the chemical industry, the hydrogen economy and sustainable chemical synthesis.
SmartCoverCare
The combat against infections at tissue contact surfaces remains a major challenge in the healthcare sector. A new development by the University of Siegen and the Amsterdam University Medical Center now offers a promising solution: a coating with antimicrobial properties that combats infections - including those caused by multi-resistant bacteria - and detects them at an early stage. This safe, effective technology could revolutionize wound care and significantly improve the healing process. The polymer network is ideal for coating catheters, tubes and permanently implanted subcutaneous instruments and sensors.
HairProtectColour
Scientists at the Niederrhein University of Applied Sciences have developed a revolutionary hair care formulation: Lignin particles provide UV protection, condition the hair, absorb excess sebum and enable reversible color changes - sustainable and versatile.Added value: Protects, conditions and temporarily colors the hair, combined with environmentally friendly clean beauty technology for everyday and professional applications.
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.
Three-phase electrode
The invention enables non-destructive, electrochemical conversion to organic compounds such as carbonyl compounds and alcohols with high energy efficiency and high current densities. This should enable the electrochemical refining of biomass.
5-HMF biopolymers
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
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.
Spray freeze-drying
Spray freeze-drying combines the advantageous properties of the well-established techniques spray drying and freeze-drying.
High-Redshift BODIPY Dyes
Fluorescent molecules are widely used in bioimaging and medicinal applications for several decades due to their high sensitivity and easy visibility.
Plasma Biocatalysis
Enzymatic reactions offer the possibility to synthesize new molecules with high selectivity and turnover.
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.
