17. A Computational Model for Interpolyelectrolyte Complexes

Matteo Chamchoum

poster contributions

Advances in modern polymer science allow to create evermore complex self-assembled structures, which are driven mostly by using electrostatic and hydrophobic forces. An example of such a system are multicompartment interpolyelectrolyte complexes (MIPECs) to be obtained by combining appropriate copolymers of opposite charge and which are stabilized by a hydrophilic corona [1]. These...

19. A Small-Angle Scattering study of the behaviour of polyelectrolytes in organic media

Mr Anish Gulati (RWTH Aachen University)

poster contributions

Polyelectrolytes are a class of material that have appealed to researchers in many different areas owing to their versatility and potential applications. The existing studies mostly deal with their behaviour in aqueous solutions due to their lack of solubility in other media. Here we have utilized carboxymethyl cellulose (CMC), which is widely available as a sodium salt, NaCMC. The solubility...

3. Limoncello and the art of mixing water and oil

Dr Leonardo Chiappisi (Institut Laue Langevin)

poster contributions

Whoever tried to prepare homemade mayonnaise, knows how much energy input the formation of water/oil emulsions require. In addition to that, in order to provide stability to the emulsion, the presence of components which stabilize the system are required. This role is played by some of proteins and the lecithin contained in the egg yolk, for the case of mayonnaise. In most of other
emulsions,...

1. Longitudinal Conical Magnetic Structure in Scandium doped M-type Barium hexaferrite

Dr Surbhi Gupta (Indian Institute of Technology, Bombay, India)

poster contributions

M-type barium hexaferrites (BaM) has attract a lot of attention due to their multiferroic and other functional properties [1, 2]. We have investigated the doped M-Type Barium hexafer-rite, BaFe12-xTxO19, where T = Sc with x = 2.5. The structural and magnetic properties were characterized using XRD, VSM and Neutron diffraction measurements. XRD analysis reveals that the samples are in single...

21. Method to simultaneously probe the bulk modulus and structure of soft compressible objects using SANS

Judith Houston (ESS)

poster contributions

An object's bulk modulus quantifies its resistance to an isotropic compression. For soft deformable colloids the bulk modulus must be known to predict their response to crowding. Here, we will present a new approach to obtain partially-deuterated, high molecular weight polyethylene glycol (dPEG), which is used to exert osmotic stress on soft objects [1,2]. In this study, microgels were used as...

4. Neutron scattering and reflectivity to study the stability of foams in a multi-scale experiment

Julien Lamolinairie

poster contributions

Liquid foams are non-equilibrium multi-scale soft structures. Moreover, the foamability of a surfactant solution as well as the metastability of the foam are still difficult to predict. In order to better understand the physico-chemical factors that affect the aging of foams at different length scales, a new columnar device was developed. It enables the simultaneous data collection from a...

16. Unravel the structure of meat analogues using SANS

Tong Guan

poster contributions

The current, unsustainable meat industry makes a growing number of meat consumers turn to plant-based meat alternatives (PBMAs). To facilitate the transition towards a (partly) plant-based diet with its health, environmental and ethical benefits, the demand for an accurate reproduction of meat-like structure, texture and mouthfeel in PBMAs is pressing. High Moisture Extrusion Cooking (HMEC)...
