A small-angle neutron scattering environment for in-situ observation of chemical processes

Hayward, Dominic W. ; Chiappisi, Leonardo ; Prévost, Sylvain ; Schweins, Ralf ; Gradzielski, Michael (2018-05-08)

A new sample environment for the observation of ongoing chemical reactions is introduced for small-angle neutron scattering (SANS) experiments which enables structural changes to be followed continuously across a wide Q-range in response to changes in the chemical environment. The approach is demonstrated and validated by performing single and multiple potentiometric titrations on an aqueous an...

Protein adsorption on nanostructured silica surfaces

Meißner, Jens (2018)

This Ph.D. thesis presents a study of the interaction of globular proteins with nanostructured silica surfaces. It aims to gain a better understanding of the consequences of a high surface curvature and confinement on the adsorption behavior and morphology of the adsorbed protein. The adsorption behavior of lysozyme and 𝛽-lactoglobulin on silica nanoparticles was studied from pH 2 to 11 and ...

Scattering techniques for nanoparticle analysis

Breßler, Ingo (2017)

This work presents three program packages implementing different methods for nanoparticle analysis, focusing on the quantitative determination of particle size distributions required in standardization of nanoparticle reference materials. In part one, classical curve fitting is discussed. It finds optimal parameters of a scattering model composed of analytical expressions. The classical curve ...

Enhancing the stability of spontaneously self-assembled vesicles - the effect of polymer architecture

Bressel, Katharina ; Gradzielski, Michael (2015)

The formation of stable vesicles with a controlled size and high stability is an important matter due to their wide application in pharmaceutical and detergency formulations and as drug delivery vehicles. One can control the size of spontaneously formed vesicles in mixtures of zwitterionic and anionic surfactants by the admixture of small amounts of an amphiphilic copolymer of the PEO-PPO-PEO t...
