The design of functional and sustainable materials requires a detailed understanding of the material properties and degradation mechanisms. In particular, the design of fully biodegradable polymers could allow a quick and controlled decomposition of materials before they accumulate in the environment…
The increasing global demand for sustainable energy solutions has driven significant advancements in photoelectrochemical (PEC) technologies, particularly for hydrogen production and biomass valorization. A key challenge for PEC cells is the selection of ion exchange membranes (IEMs) that ensure efficient…
Interfaces formed between porous carbon materials and ionic liquids (ILs) play an essential role in catalysis as well as in electrochemical energy storage and energy conversion. Profound knowledge about the formed local structures on a molecular level is essential to create the desired physicochemical…
Drug-delivery systems have attracted considerable attention due to their potential to increase the bioavailability of certain drugs and mitigate side effects by enabling targeted drug release. Reversibly core-cross-linked block copolymer micelles providing a hydrophilic and potentially nonimmunogenic…
Various poly(methyl methacrylate) (PMMA) and poly(acrylonitrile) (PAN) coated silica nanoparticles were synthesized via chain transfer polymerization with the goal to assess the coating behavior and characterization of polymer coated silica nanoparticles with monomers of different reactivities. The particles…

Optical spectroscopic methods such as Raman spectroscopy offer several advantages for the analysis of water-soluble polymers (WSPs). There is often no need for complex sample preparation, and measurements are usually rapid, mostly non-destructive and no harmful chemicals are required. In this work, we…
To exploit the full potential of these naturally occurring biopolymers, they can be chemically modified. In particular, the hydroxy group, which occurs in all polysaccharides, can be functionalised. Most common reaction is esterification, and less frequently etherification (primarily technical products…
Nature's impressive complexity surrounds our everyday life and has fascinated generations of scientists trying to solve the riddle behind the underlying mechanisms that drive our world at the most fundamental levels. With many failed attempts to provide comprehensive and non-contradictory explanations,…

Abstract Elemental sulfur has shown to be a promising alternative feedstock for development of novel polymeric materials with high sulfur content. However, the utilization of inverse vulcanized polymers is restricted by the limitation of functional comonomers suitable for an inverse vulcanization. Control…
Biomedical applications such as drug delivery, tissue engineering, and functional surface coating rely on switchable adsorption and desorption of specialized guest molecules. Poly(dehydroalanine), a polyzwitterion containing pH-dependent positive and negative charges, shows promise for such reversible…
