This proposal would like SANS time to better understand the LAS phase diagram. This has been prompted by recent experiments which show the system is not fully understood under...

We will use time-resolved SANS measurements to follow the self-assembly kinetics of insulin from protein monomers to fibrils. By measuring through a well-defined lag phase we...

The self-assembly of (cyclic peptide)-polymer conjugates provide a versatile and functional platform for the precise design of polymeric supramolecular nanotubes. Moving the...

The consumer demands for functional food have increased the interest for encapsulation of bioactive compounds in the food industry. Encapsulation is crucial, since these...

Complexes prepared from cationic, dichain lipid (L) vesicles and negatively charged siRNA (R), with and without positively chargely targeting peptides (P) known as LR or LPR...

An eggshell membrane polypeptide is highly surface active and effective at emulsion stabilization. We explore how to use SANS to study the interfacial layers surrounding the...

In this proposal we will investigate hypothesized asymmetric diffusion of water into lipid cubic (QII) phases. This asymmetric diffusion, which is relevant to the behavior of...

Nanoemulsions (NE) i.e. nanoparticles containing a fluid lipid or oil dispersed in water and stabilized by a surfactant particles have attracted considerable attention as...

The behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We...

We have been focusing on two component gel networks. Here, both components can individually form gels. In a mixed system, the LMWG can either co-assemble or self-sort. In a...

Our group has been working cellulose nanofibrils (OCNF) which form hydrogels in the presence of certain additives. Previously, we have studied the effect of salt, single...

Addition of multivalent salts to water soluble polyelectrolytes, such as sodium carboxymethyl cellulose (NaCMC), induces conformational change to the polyelectrolyte structure,...

Nascent 'disentangled' block copolymers of Ultra-high Molecular Weight Polyethylene (UHMWPE) with a reduced number of entanglements were synthesized having protonated (hPE) and...

This proposal builds upon the successful study of a cationic copolymer capable of forming polymer micellar-like aggregates, simply by reducing pH (D33 at ILL 9-12-433 see...

Endocytosis plays a central role in allowing the selective transport of molecules, via membrane-derived vesicles, into cells. Vesicle formation is controlled by a complex...

Long-term stable CO2 foams were generated under high temperature (120 ºC) and high pressure (12 MPa) (HPHT) in our laboratory using a C22-tailed weak cationic surfactant,...

Complex coacervates have been studied for a long time for their medical applications and unusual physical-chemical properties: they are dense networks of poly-electrolytes, that...

The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents. The successful development of...

We request two days’ beam time on SANS2D for the study of radiation-grafted anion-exchange membranes, both dry and hydrated under different ratios of D2O/H2O. These materials...

The aim is to improve understanding of solution properties and aggregation of hydrotropes and alkyl¿hydrotropes, and the relationship with common surfactants. Although they are...
