21. Nanofluidic Scattering Microscopy for Single Particle Catalysis
Abstract : Heterogeneous catalysis concerns material formulations – catalysts – that can assist a chemical reaction by improving its rate or selectivity, by lowering activation barriers and altering the energy landscape. The core of catalysts are often tiny metal particles that provide a large reaction surface at a small volume, as well as low coordination sites whose type and abundance depends on particle size and shape.

22. Nanocellulose Oxidation - Fundamentals and Application in Hydrogels
Abstract : The adaptable surface chemistry of cellulose nanocrystals (CNCs) makes them outstanding; it provides colloidal stability, which is essential for engineering use, to commercially-available CNCs. Colloidal stability is achieved by the bulky negatively-charged sulfate half-ester groups on the surface that it manufactures itself via the use of sulfuric acid. READ MORE

23. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation
Abstract : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. READ MORE

24. Early Hydration of Portland Cement
Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE

25. Fucoidan-Mimetic Glycopolymers : Synthesis and Biomedical Applications
Abstract : The marine polysaccharide fucoidan has demonstrated several interesting biological properties, for instance being antiviral, anticoagulant, anti-inflammatory, anticancer, and platelet activating. Many of these properties are desirable for various biomedical applications. Yet, there are few reports on fucoidan being used in such applications. READ MORE
