In recent years much progress has been made in the design of surfactants that are soluble in liquid CO2; hence these additives able to modify physicochemical properties...

This proposal constitutes part of our ongoing study towards understanding how keratin, an important protein component of hair and skin, interacts with ionic surfactants using...

This proposal aims to explore aggregation behavior of common surfactants in magnetic ionic liquids (MILs) and to investigate the effect of a magnetic field on aggregate size,...

Asymmetry across biological membranes is vital for a wide range of organelle and cellular functions. Significant differences in lipid composition have been found between the...

SANS will be used to determine the structure of nanotube dispersions formed by H-bond stacking of cyclopeptides coated with a sheath of stabilizing polymer. Cyclopeptide...

This proposal seeks to exploit contrast variation SANS to study a multi-component system, spanning a wide range of colloidal length scales. The multi-component system under...

Approved proposal under the ICRD Scheme Proposal ICRD0005

The research topic is encapsulation of a hydrophobic drug, flurbiprofen, using novel amphiphilic graft copolymers (AGCs). The AGCs of interest are shown in Figure 1: Preliminary...

Diblock co-polymers consist of two polymer chains with different chemical properties tied together at a central linking block. The interactions between the two blocks result in...

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...

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 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...

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...

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,...

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...

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...

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

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

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...

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...
