Recycling of coated light metals
Much of Europe has a circular economy in which most metallic materials, such as various construction materials and beverage cans made of aluminum, are recycled. Fundamentally, two different forms of aluminum is used in industry.
Measurable latent heat storage systems
Latent heat stores (PCM stores) are heat stores that store a large proportion of the thermal energy supplied to them in the form of conversion enthalpy, the energy required for the transition from one phase (solid/liquid/gaseous) to another. An invention by Westfälische Hochschule and Bochum University of Applied Sciences can determine the stored heat content using piezoelectric elements.
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.
FishFlowFilter
Researchers at the University of Bonn and Fraunhofer UMSICHT have developed an innovative microplastic filter that is inspired by nature. The bionic filter system uses a special flow technology to remove over 95% of microparticles from wastewater - without clogging and without filter changes. A smart self-cleaning function ensures efficient and sustainable separation of microplastics.
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.
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.
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.
High-voltage macro cell
A new type of high-voltage macrocell from Dortmund University of Applied Sciences and Arts makes it possible to store energy with a total voltage of up to 20,000 volts. For this purpose, individual modular storage modules (“FOXe”) with a voltage of up to 1500 volts are joined together in tube systems to form a high-voltage macrocell.
Rotor blades for low wind speeds
A rotor geometry modeled on maple seeds has been developed that enables more efficient operation of wind turbines and fans. It is a geometry that is easy to manufacture and cheaper to produce than conventional rotor blades.
Fin plate
The device is particularly advantageous for the transportation and assembly of wind turbines. Vortex-induced vibrations are significantly reduced or avoided. In principle, the device can be used for all cylindrical structures (e.g. pillars) that need to be protected from vortex-induced vibrations.
Rain gutter water level monitoring
Gutter blockages caused by leaves, dirt and other debris can prevent the flow of water in the gutter, which can lead to considerable damage and problems. Water can spill over the sides of the gutter, causing water damage to the foundations or other parts of the building. In addition, standing water in the gutter can attract insects such as mosquitoes and serve as a breeding ground. In colder climates, the accumulated water can freeze and form ice dams that damage the roof or the gutter itself. Researchers at the University of Siegen have found an innovative solution to this problem by equipping the gutters with a water level sensor.
Climate-neutral steelmaking
Novel raw material input for the production of green steel. In addition to hydrogen, a carbon-containing aerosol is used to produce green steel.
MultiXQuant
New analytical method for quantification in lightweight materials such as plastics, polymers or refuse-derived fuels using X-ray fluorescence analysis.
Thermoelectric water heat pump
With the new thermoelectric water heat pump, drinking water can be heated to the desired temperatures in an energy-saving manner. For this purpose, the energy is extracted from heating water with a low flow temperature, which has been heated by means of solar thermal energy, for example, and fed to the drinking water to be heated.
Thermoelectric exhaust-air heat pump
With the new heat exhaust pump, the heat of a ventilation system can be efficiently recovered by means of thermoelectric elements. The heated fresh air can also be heated via the temperature of the exhaust air. The exhaust air heat pump is also suitable for cooling buildings.
Smart grid expansion
Intelligent power grids can monitor and regulate themselves independently. A new process from the University of Wuppertal makes it possible to stabilize the voltage in grids by installing control units, as well as avoiding overloads.
Detecting ionizing radiation
Ionizing radiation is harmful to humans and the environment even in the smallest quantities. Therefore, radioactive materials must be continuously monitored in hospitals, mines or reprocessing plants. A novel semiconductor sensor can analyze ionizing radiation in an integrated microfluidic system (in-situ).
Effective hydrogen production
At the Ruhr University Bochum an effective method was developed with which the coating of an electrode can be achieved with high long-term stability, especially during electrolysis such as alkaline water splitting. Due to the coating of the electrode surface with catalytically active material, a significant reduction in the required cell voltage is achieved.
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.
Method for current measurement in half-bridge topologies
A number of different instrument transformers are used to determine voltage and current in regulated power electronics. Current measurement becomes more and more difficult with increasing current intensity, especially since the switching frequencies increase due to the use of modern (e.g. GaN) transistors and parasitic properties of the sensors must be minimized.
GridMaximizer
The electrical power grid is undergoing a major transformation. Increasing numbers of decentralized feeders have been added in recent years and, in the future, there will be a large number of charging stations for electric vehicles that temporarily draw a large amount of electrical power from the power grid.
