|Materials synthesis and processing techniques within the Materials Chain span length scales, from the nanometer for novel functional materials to meters for smart or adaptive structures.
In the field of nanostructured materials, Materials Chain researchers have a unique expertise in gas- and liquid-phase synthesis of functional nanomaterials, from fundamental experiments and process simulation up to the kg/h production scale.
|Targeted synthesis beyond powders is a core topic for making functional materials suitable for applications such as catalysis, (photo)electrochemical water splitting, electrochemical energy storage, photovoltaics and light emitters as well as magnetic and electronic devices. This involves the build-up of highly-defined layered structures, mesoporous and nanoparticle-decorated materials through modular multi-stage processes as well as wet-phase processing of particles in organic matrices for microscopic structuring, stable coating, and electrical contacting. Establishing defined layered structures on complex surface topology (core-shell particles, embedded particles, particle-decorated structures, layered 3D-framework structures) is the key for applications that require functional interfaces to be exposed to a certain environment, e.g., in electrocatalysis and battery materials.
Advanced ingot or powder metallurgy processing routes provide access to kg-scale amounts of alloys with specific compositions and microstructures, a prerequisite for a breakthrough in the field of shape-memory alloys and metallic high-performance materials. Controlling the materials structure during processing, metal shaping, and operation (i.e. functional fatigue) is core and closely linked to the characterization and modeling HUBs within the Materials Chain.
In this context, UDE’s NanoEnergyTechnologyCenter (NETZ) serves as a platform for materials synthesis and processing, and its state-of-the-art facilities allow for the coupling of particle synthesis with colloid and polymer chemistry, coating, sintering, and laser processing in a single production chain, and for the investigation of scaling-up. RUB’s Center for Interface-Dominated High-Performance Materials (ZGH) aims to develop new metallic, semiconducting, and dielectric materials through a comprehensive understanding and design of interfaces. ZGH also exploits new combinations of structural and functional properties.
The Materials Chain also makes significant contributions in the fields of manufacturing research. Flexible manufacturing of lightweight components has been a core topic for years leading to several industrial transfer projects. New manufacturing technologies in the field of metal forming have been invented and developed. The concept of product-property prediction and control in the forming of components has been introduced into the international scientific community by Materials Chain scientists. The latest research activities aim at paradigm changes in component design and metal forming processes considering a multi-scale view of damage evolution. TUDo’s Research Center for Industrial Metal Processing (ReCIMP) is fully financed by industry, and since 2013 has served for transferring fundamental research into industrial applications and for identifying and investigating unresolved physical phenomena that are hampering technological developments.
