Ph.D. thesis: Development of hybrid composites compensating shrinkage at pyrolysis

This work aims to design and describe suitable methods of shrinkage compensation and/or control for the preparation of matrix composites and their effect on microstructural changes and fracture behaviour of hybrid composite materials containing such adapted matrix and ceramic fibres. The main goal of the doctoral thesis will be the design and characterization of hybrid…

Application of Molecular Dynamics in Materials Research

Molecular Dynamics (MD) is a computer simulation method that describes the motion of atoms and molecules. The trajectories of atoms and molecules are typically determined by numerically solving Newton’s equations of motion for a system of interacting particles, where the forces between particles and their potential energy are often calculated using interatomic potentials or molecular…

Functional nanolayers for the real world

The student will become familiar with the procedures for the preparation, characterization, and application of functional nanolayers with so-called antifouling properties during their internship, which can have wide applications in the real world. They will learn methods such as post-modification of polymer layers to anchor bioreceptors to the surface, achieving targeted functional properties of the…

Application of Cohesive Elements in Modeling Fracture of Heterogeneous Materials

The fracture process of concrete is a complex mechanism influenced by its highly heterogeneous internal structure: matrix/cement paste, aggregate, and pores. Damage development occurs at the interface between the cement paste and aggregate, where microcracks can form. The offered internship will focus on 2D/3D numerical modeling of this process using cohesive elements available in ANSYS…

Determining the endurance life of selected construction materials

Current methods for determining the fatigue life of concrete structures focus on reducing stresses in structural elements. However, this approach only considers the degradation of mechanical properties due to cyclic loading and not the gradual development of microcracks. This topic is primarily concerned with the experimental determination of the fatigue life of construction materials, particularly…

Materials for Efficient Hydrogen Storage

Efficient hydrogen storage is a challenge of the future. The aim of this work will be primarily the preparation of materials for hydrogen storage, creating graphs from measured data, and possibly assisting with their processing. At the same time, the student will also become familiar with working with an electron microscope. https://www.ipm.cz/

Measurement of the speed of crack propagation in a PE pipe

A well mapped crack propagation mechanism is the basis for accurate lifetime prediction of various components. While crack propagation rate measurement techniques are relatively well developed for metallic materials and the mechanisms are well described, this is not the case for polymeric materials. This work focuses on the measurement of crack propagation rate in various…

Photoswitches – graphene functionalization using chiral organic molecules

In the current project, we are particularly interested in the covalent attachment of small organic molecules to 2D materials[i] and the linking of the latter via the former. While in most of our projects, the organic molecules used for surface modification are commercially available or readily available from such, some projects require more extensive synthetic efforts.…
