The magnetic-field-induced assembly of magnetic nanoparticles (NPs) provides a unique and flexible strategy in the design and the fabrication of functional nanostructures and devices. We have investigated the field-induced self-assembly of core-shell iron oxide NPs dispersed in toluene by means of small angle neutron scattering (SANS). The form factor of the core-shell NPs was characterized and an ... More

We present liquid crystal geometries experimentally found for star-polyphilic molecules as the basic building block. Star-polyphiles are small molecules, bearing three mutually immiscible chains attached to a common center [1,2,3]. Like conventional lipids or surfactants (that usually have two immiscible chains), such molecules self-assemble to form lamellar, hexagonal, micellar cubic and bicontin ... More

Contact between cells and their surrounding environment is mediated by cell surface glycans that can be in the form the form of glycolipids, glycoproteins, and glycocalix polysaccharides. These saccharide layers act as stabilizers or repellers to maintain a certain distance between neighboring cells, and create hydrodynamic pathways for the diffusion of ions and molecules across the cell membrane. ...

The interaction of surfactants and protein is of relevance for applications such as surface cleaning and the removal of protein from porous separation membranes. We studied the co-assembly of the globular protein lysozyme (Lyz) with the cationic surfactant cetylpyridinium chloride (CPC) in the tubular pores of SBA-15 ordered mesoporous silica (pore diameter 8 nm) using small-angle neutron diffract ...

In this study we present a method for determining the profile of solute molecules confined between two interfaces. Stacks of oriented bilayers supported on a quartz slide are useful a model system to study the interactions of different molecules with planar interfaces. The samples are effectively one dimensional crystals. In this case the unit cell includes the bilayer and inter layer solution a ... More

The three-dimensional architecture of biological membranes has functional consequences for living cells. In the outer leaflet of the plasma membrane, lipids are thought to organize into ordered fluid domains, with diverse evidence supporting participation of these “rafts” in membrane processes including protein sorting and signaling. Cells also actively maintain an asymmetric distribution of d ... More

Magnetic nanoparticles (NPs) have attracted much interest for decades due to their potential applications in magnetic data storage, ferrofluidic systems and nanomedicine. In particular, heterodimer NPs composed of two different NPs in close contact are potential candidates to achieve multifunctional materials combining various physical properties. Here we focus on antiferromagnetic (AF) MnO NPs as ... More

Australian Nuclear Science and Technology Organization (ANSTO) for more than ten years successfully operates first Small Angle Neutron Scattering instrument QUOKKA [1] and in January of year 2016 commenced user operation of the second SANS instrument, BILBY [2]. The inspiration for BILBY is the D33 instrument located at the Institut Laue-Langevin [3]. Similar to D33, BILBY exploits neutron time-of ... More

Synthesis of nanoparticle superlattices, which may provide new emerging properties through collective coupling of nanoparticles, are of great interests for various potential applications as well as its own scientific merit. Currently, exciting progresses are being made for the fabrication of single, binary, and multi-component nanoparticle superlattices with various symmetries. In this talk, a few ... More

We report about the manipulation of magnetism of self-assembled iron oxide nanoparticle (NP) monolayers on top of BaTiO3 (BTO) single crystals. Magnetoelectric coupling (MEC) as shown in both the magnetization and magneto-electric ac susceptibility (MEACS) measurements is observed. Both the magnetization and MEACS as function of temperature show abrupt jumps at the BTO phase transitions temperatur ... More

Since fullerenes were discovered and especially in the last decades, potential applications of fullerene solutions in various fields including electronics, optics, cosmetics, and pharmaceutics were intensively developed and studied [1-2]. Due to a good solubility in different nitrogen-containing solvents, the liquid systems based on the fullerenes C60 and C70 show a high sensitivity of optical pr ... More

Neutron imaging and scattering give data of significantly different nature and traditional methods leave a gap of accessible structure sizes at around 10 micrometers. Only in recent years overlap in the probed size ranges could be achieved by independent application of high resolution scattering and imaging methods, however without providing full structural information when microstructures vary on ...

Alzheimer’s disease (AD) is a devastating neurodegenerative disease caused by the formation of senile plaques, primarily consisting of amyloid-beta (Ab) peptides. The crucial role in this process is imparted by peptide-membrane interactions, changing the structural properties of membrane. These changes are known to be modulated also by membrane composition. In particular, cholesterol increases t ... More

Originally designed to investigate large to small unit-cells in partially ordered systems such as membranes or clays, the D16 cold-neutron diffractometer at the ILL evolved from the original design to become a highly versatile instrument with high monochromatic flux, broad q-range and high $\Delta q / q$ resolution. The instrument was upgraded during the 2013-2014 shutdown of the high-flux reac ... More

To evolve biological and biomedical applications of hybrid biomolecule−lipid materials, including in meso protein crystallization and drug delivery, an understanding of the location of the biomolecules within the bicontinuous cubic phases is crucial. Theoretical modeling has indicated that proteins and additive lipids might phase separate locally and adopt a preferred location in the cubic phase ... More
