Klemm, B. (author)
Signal transduction in living systems enables adaptive and interactive response to external stimuli. These rudimentary primary processes developed by nature are currently absent in synthetic materials. Implementing these processes in materials can have widespread advances in regenerative medicine, diagnostics or nanomachines. Taking inspiration...

Spitzbarth, B. (author)
Nature has inspired countless researchers in their quest to understand the phenomena we observe and utilise their findings to develop new technologies. This becomes especially apparent in systems chemistry, which heavily draws inspiration from natural systems in its pursuit for the understanding and development of chemical reaction networks ...

Ghanbari, E. (author)
This thesis reports on the “structure and supramolecular assembly in multi-component organogels”. It guides readers how the aim of this research has been achieved by division of the main question into subgoals in different chapters. This introduction chapter gives a brief overview on the research theme, it is followed by the second chapter...

Piergentili, I. (author)
Living cells adapt to changes of their environment through a cascade of chemical reactions regulated by enzymes. Each cellular pathway contains a series of enzymes, which are capable of receiving and translating a specific chemical or physical signal into a biological response. Taking inspiration from nature, enzymatic mechanisms can be...

Li, G. (author)
Nature has proven to be a great source of inspiration for scientific research and technological innovation in various areas: food, medicine, architecture, chemistry, materials, algorithms, and many other fields. At the basis of sophisticated functions associated with life in nature are all kinds of chemical reactions which are mainly regulated...

Breve, T. (author)
Smart materials are materials that are capable of responding in a programmable and predictive manner. Such materials respond to a broad variety of internal and external triggers and modulate one or more material properties accordingly. Common material responses are controlled release, color changes, morphological changes or changing the...

van Assenbergh, S.P. (author)
Generation of grip on soft tissue in the surgical field is most commonly done with forceps that generate friction grip, that is, the translation of normal (pinch) forces into shear forces. Errors made with these surgical grippers are often force-related: applying too low pinch forces results in slipping of the tissue out of the gripper, and too...

Fan, B. (author)
This thesis describes the experimental development of new dynamic hydrogels based on reversible thiol conjugate additions. Redox-controlled hydrogels and self-healing injectable hydrogels have been achieved by introducing reversible thiol conjugate additions to crosslink polymers, leading to hydrogel formation. The overall objective in this...

van der Helm, M. (author)
The entire research described in this thesis is part of the larger field of Systems Chemistry. This field of chemistry deals with the understanding of the complexity of biology by mimicking biochemical reaction networks with emergent properties attributed to the entire system. In particular, this research focuses on the design of artificial non...

van Helmond, W. (author)
fingerprints are a commonly exploited type of evidence and can be crucial in a criminal investigation. The process of individualization or exclusion of a donor relies on the comparison of ridge detail characteristics between a fingermark, found at a crime scene, and reference fingerprints, collected under controlled conditions (either or not...

van Rossum, S.A.P. (author)
Nature is capable of constantly adapting some of its assembled structures in response to external and internal signals. For instance, microtubuli grow and shrink upon cell division and cellular transport. Furthermore, actin fibers play a major role in muscle contraction and cell signaling. To achieve these transient functions, such assembled...

Piskorz, T.K. (author)
In this thesis, we explore the application of various molecular simulations techniques to give insights into the self-assembly of supramolecular systems.<br/>Chapter 1 explains the importance of molecular simulation to study the selfassembly process. In chapter 2 we study self-assembly of a derivative of 1,3,5-triamidocyclohexane (CTA) using...

Wang, Y. (author)
Molecular self-assembly has been realized as a powerful approach to control the organization of materials from molecular to macroscopic length scale. While for a long time molecular self-assembly has focused on the investigation of systems involving a single component and under thermodynamic equilibrium. In recent years the interests are...

Mytnyk, S. (author)
Growing importance of hydrogels in various areas of human life has led to increasing need in controlling their properties, which is generally achieved by adjusting hydrogels shape and microstructure. Even though standard microfabrication and microstructuring techniques can be currently applied in hydrogel research, the variety of properties of...

Trausel, F. (author)
Cells react to the environment by changing the activity of enzymes. Catalysts, such as enzymes, speed up reaction rates by lowering the activation energy of the reaction. Changing reaction rates by altering enzyme activity is used to temporarily increase the production of, for instance, a hormone or to change the mechanical properties of a cell....

Self-assembly of amphiphilic block copolymers in aqueous solution provides a versatile tool to create complex and functional micelles with various nanostructures, such as spherical, cylindrical and bilayer structures. As an important class in these structures, nanofibrillar micelles have attracted growing interest due to their unique properties...

Nature is full of life, which is driven by the numerous biochemical processes that occur in living organisms. Many motifs are universal regardless of species, such as enzymatic networks, self-assembly and reaction-diffusion. This work examines the development of novel soft functional materials via self-assembly and reaction-diffusion approaches....

Living creatures exists for an important part out of soft material, such as skin, organs and cells, that are out-of-equilibrium formed by the self-assembly of molecular building blocks. Natural materials are continuously active with dynamic processes occurring, such as growth, shrinkage and transport mechanisms under the consumption of energy....

Latsuzbaia, R. (author)
In this thesis, I discuss a novel idea of fuel cell catalyst regeneration to increase lifetime of the PEM fuel cell electrode/catalyst operation and, therefore, reduce the catalyst costs. As many of the catalyst degradation mechanisms are difficult to avoid, the regeneration is alternative option to prolong catalyst lifetime. In the thesis, I...
