Various engineering material concepts can be fabricated from cellulose. The starting point can be the cellulose polymer, nanoscale intermediates such as cellulose nanofibers (CNFs), and macroscopic cellulose fibres extracted from plants. The material concepts exhibit good mechanical performance, unique hierarchical structuring and various functional properties, making them suitable for various...
Beyond crystalline graphite, planar sp2 hybridized carbon can make a wide array of different structures and therefore materials: From geologically formed asphaltenes, to new synthetic materials such as carbon nanotubes. Many of these materials are non-crystalline, making non-ambiguous structural determinations is therefore difficult. In this talk we will outline the combined use of wide...
Food emulsions may be either stabilized by amphiphilic milk-based or sustainable plant-based proteins, which affect the interfacial and emulsion stabilization mechanisms on a macro- and microscale of length and time. To understand these mechanisms in detail different length scales from molecular to macroscopic distances as well as time dependent mechansims need to be investigated.

A coating in general serves two purposes, protection of the coated substrate and decoration of the coated object. Modern automotive coatings consist of multiple layers with each layer specialized to provide protective or appearance properties to the overall coating. The formulation of a single layer can easily contain dozens of individual components. The main component of an organic coating...
Efficient neutron transport through neutron guides is the basis for the high performance of modern neutron scattering instruments. The combination of special guide profiles and high reflectivity supermirror coatings allows the properties of the neutron beam to be tailored to the needs of the experiment. In addition, a variety of substrate materials (different glasses, different metals,...
Waterborne latex films, obtained from the dispersion of latex particles are of particular interest due to the non-content of volatile organic compounds (VOC), often mandatory under environmental legislation.1 However, abrupt water penetration inside the films restricting their lifespan and deteriorating the shining of the coating. In order to prepare efficient and solvent-free coatings with...
Research on the physico-chemical properties of microbial biosurfactants is a very active field as these compounds are of increasing interest to industry due to their enhanced biodegradability and their derivation from renewable sources [1]. To achieve the goal of replacing existing surfactant formulations with this greener alternative, a solid knowledge of the latter’s properties is...
Polysaccharides, as major components of natural origin, have garnered extensive attention and utilization across diverse fields, including the nutritional manufacturing sector. Due to their advantageous properties such as safety, stability, biocompatibility, biodegradability and nontoxicity, polysaccharide-based complex systems have a significant potential in the fields of cosmetics,...
Binary liquids may show critical composition fluctuations if the temperature and composition are close to the critical point. When adding ionic surfactants (or antagonistic salts) the whole system gets dominated by the ions that are arranged locally in lamellae that display the charge density waves. The domains only fluctuate along the surfaces in 2 dimensions on short time scales. Only at...
