Research in the Materials Research Department (MRD)

Materials are ubiquitous. They affect every aspect of our daily lives. They are the basis for today’s cutting edge technologies and the availability of novel materials and efficient processing routes determine the pace at which innovations can proceed. This makes materials important to help mankind to find the right technological answers in the fields of energy, transport, health, housing and environment.

SFB/TR 103 – From Atoms to Turbine Blades

The SFB/Transregio 103 is a collaborative research center funded by the German Research Association DFG. It has reached its third four year finding period and focusses on Ni-base superalloy single crystals (SX).

MRD Newsletter Issue 13

Fundamental aspects of single crystal solidification processing

Project B7 of the SFB/TR 103 aims at contributing to a better understanding of the formation and nature of crystal defects in single crystal Ni-base superalloys.

MRD Newsletter Issue 13

High entropy alloys in SFB/TR 103

In order to enable further optimization of superalloys, there must be systematic investigations into the influence of individual alloying elements on several aspects. Project B8 serves this purpose by investigating the influence of Co, Ni, Cr, and W, on phase stability, diffusion kinetics, the energy of planar defects, all of which are playing major roles in creep of superalloys.

CRC/TRR 247 „Heterogeneous Oxidation Catalysis in the Liquid Phase – Mechanisms and Materials in Thermal, Electro-, and Photocatalysis”

The CRC/TRR 247 „Heterogeneous Oxidation Catalysis in the Liquid Phase – Mechanisms and Materials in Thermal, Electro-, and Photocatalysis” aims at bringing heterogeneous oxidation catalysis in the liquid phase to a level of fundamental understanding that is comparable to metal catalysis in the gas phase, i.e. to unravel the nature of the catalytically active sites and the reaction mechanisms.

Thermal Catalysis: Activity and Selectivity Patterns of Transition Metal Oxides in Different Oxidation Reactions

In these kinetic experiments, conversion and the selectivities to the various products comprising ketones, acids, peroxides, or epoxides are determined as a function of the process conditions, allowing us to derive rate laws.

Uncovering Process-Structure Relationships Through Novel Microstructural Characterization and Data Analysis

Predicting the effect that chemistry and processing have on the microstructure of any material is a highly valuable proficiency. The morphological and micromechanical properties of individual phases and features, together with the nature of their interactions, are ultimately responsible for the emerging mechanical properties. Deep knowledge of this cause-effect chain is critical to enabling the tailored materials design, the core topical subject of the ever-digitizing fields of Materials Science and Technology.

CRC/TR 287 - BULK-REACTION: A new Collaborative Research Centre on particle systems in gaseous fluids

The Collaborative Research Centre/Transregio 287 BULK-REACTION explores the interaction of physical and chemical processes in reacting and moving dense particle systems passed by a gaseous fluid. BULK-REACTION combines the methods and expertise from reactive fluid mechanics with particle technology in a new multi-scale approach, ranging from microscopic pores inside particles, to the void spaces between particles, up to complete systems of industrial scale. Reacting dense particle systems form the basis of a multitude of processes and are present in a wide variety of industrial sectors (e.g. for energy storage solutions

RUB’s Participation in International Max Planck Research School SurMat

Since 2000, International Max Planck Research Schools (IMPRS) have been established by the Max Planck Society (MPG) to promote young materials researchers. Talented junior scientists can earn a doctorate degree in excellent research environments. Looking back at the beginning and development of IMPRS SurMat which ends now.

MRD Newsletter Issue 13

RUB’s Participation in International Max Planck Research Schools RECHARGE and SusMet

The goal of the IMPRS RECHARGE is to decouple the primary photochemical processes that lead to capturing of solar energy from its later uses in technology or mobility. Since January 2022, research in the IMPRS SusMet focuses on the exploration of carbon-free sustainable metallurgy, employing hydrogen as reducing agent, direct electroreduction (electrolysis) and plasma synthesis.
