New Insights into the Solid-liquid Interface Exploiting Neutron Reflectivity
Publication date: Available online 4 April 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): R.J.L. Welbourn, S.M. ClarkeAbstractWe outline recent progress exploiting neutron reflectivity for structural and compositional investigations of the solid-liquid interface. There has been extensive activity in this area, with key areas of development: (i) an increased range of accessible substrates (e.g. metals and minerals), (ii) novel liquid phases, and (iii) strong themes in electrochemistry (e.g. batteries), corrosion, polymers and increasing application of extreme conditions.Graphical abstract (Source: Curr...

Enhanced rheological properties and performance of viscoelastic surfactant fluids with embedded nanoparticles
Publication date: October 2019Source: Current Opinion in Colloid & Interface Science, Volume 43Author(s): Olga E. Philippova, Vyacheslav S. MolchanovAbstractA combination of viscoelastic surfactants with nanoparticles gives a new class of functional self-assembled materials promising for a large variety of applications. Nanoparticles improve the rheological properties of these systems because of the incorporation into the network of entangled wormlike micelles by linking to micellar end-caps, thus leading to elongation or cross-linking of the micelles. The present article reviews recent studies of these hybrid systems. Mec...

Applications of small-angle X-ray scattering/small-angle neutron scattering and cryogenic transmission electron microscopy to understand self-assembly of surfactants
Publication date: August 2019Source: Current Opinion in Colloid & Interface Science, Volume 42Author(s): Yaxun Fan, Yilin WangAbstractThe self-assembling structures and dynamics of surfactants determine most of their macroscopic physicochemical properties and performances. Herein, we review recent work on the self-assembly of surfactants by small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) in conjunction with cryogenic transmission electron microscopy (Cryo-TEM) from the perspective of researchers having only limited theoretical knowledge of these techniques but expert in surfactants. Emphasis ...

Recent developments in the application of X-ray and neutron reflectivity to soft matter systems
Publication date: Available online 16 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Maximilian W.A. SkodaAbstractMany interesting physical, chemical and biological phenomena occur at interfaces between nanometre scale layers of soft condensed matter. Theses often complex systems lend themselves to study by X-ray (XRR) and neutron reflectivity (NR). The application of these techniques to such systems is extremely wide spread and provides unique insights into their structure and dynamics. This review presents a snapshot of recent activity in this research area and identifies trends in the applica...

Tailoring the interfacial assembly of colloidal particles by engineering the mechanical properties of the interface
Publication date: Available online 14 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Armando MaestroAbstractFluid interfaces can be used as a platform for promoting the direct and spontaneous self-assembly of colloidal particles, where the driving force is the reduction in interfacial energy. In addition, fluid interfaces allow fine-tuning of the particles ensemble by an external force, such as the presence of an imposed interfacial flow, or by engineering the inter-particle interactions dictated by the interplay of interfacial forces. As a consequence, a wide-ranging set of interfacial structur...

Universal dynamics of dilute and semidilute solutions of flexible linear polymers
Publication date: Available online 14 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): J. Ravi PrakashAbstractExperimental observations and computer simulations have recently revealed universal aspects of polymer solution behaviour that were previously unknown. This progress has been made possible due to developments in experimental methodologies and simulation techniques, and the formulation of scaling arguments that have identified the proper scaling variables with which to achieve data collapse, both for equilibrium and nonequilibrium properties. In this review, these advances in our understand...

Simple Yield Stress Fluids
Publication date: Available online 14 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Ian FrigaardAbstractRecent years have seen a flurry of research on yield stress fluids, approached from different perspectives (physico-chemical, rheological and fluid mechanical), considering different length- and timescales, using a range of tools: experimental, computational and analytical. In this context it has been common to denigrate the simple models of yield stress fluids for their various acknowledged deficiencies and proffer improved models. Here we push back, in defence of the century-old simplicity,...

Nanodiamonds for advanced optical bioimaging and beyond
Publication date: Available online 8 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Neeraj Prabhakar, Jessica M. RosenholmAbstractNanodiamond (ND) has emerged as an intriguing material in recent years both industrially and in research. During the last decade, ND has furthered its way into the biomedical field, due mainly to its inherent photoluminescent properties. In parallel, the development of advanced biomedical imaging methods and techniques have faced a steep upswing, making these two a ‘perfect match’. The optical and physical properties of ND can be tuned, rendering them highly inter...

Recent advances in neutron reflectivity studies of biological membranes
Publication date: Available online 5 March 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Jeremy H. LakeyAbstractBiological membranes are critical living interfaces which not only compartmentalise cells but also provide specific surfaces upon which biochemical reactions take place. Their study is essential for our understanding of life and disease, and also for the development of new pharmaceuticals. Since they are dynamic structures reliant upon the surrounding aqueous phase for their activity, techniques which can probe them at a molecular scale under physiological conditions are crucial to understa...
