Effect of annealing and silylation on the strength of melt-spun Ni-Mn-Ga fibres and their adhesion to epoxy

Véronique Michaud, Yves Leterrier, Susanne Glock, Edgars Sparnins

Single crystals of ferromagnetic Ni-Mn-Ga shape memory alloys show magnetic-field and stress induced twinning, leading to shape memory. Adaptive composites can thus be produced by embedding single crystalline particles or bamboo-structured Ni-Mn-Ga fibres ...

Simultaneous extension of both basic microstructural components in scleractinian coral skeleton during night and daytime, visualized by in situ Sr-86 pulse labeling

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon

Using in situ (12 h) pulse-labeling of scleractinian coral aragonitic skeleton with stable 86Sr isotope, the diel pattern of skeletal extension was investigated in the massive Porites lobata species, grown at 5 m depth in the Gulf of Eilat Several microstr ...

Hard sphere-like glass transition in eye lens alpha-crystallin solutions

Nicolas Dorsaz, Giuseppe Foffi

We study the equilibrium liquid structure and dynamics of dilute and concentrated bovine eye lens alpha-crystallin solutions, using small-angle X-ray scattering, static and dynamic light scattering, viscometry, molecular dynamics simulations, and mode-coup ...

Impact properties of shear thickening fluid impregnated foams

Véronique Michaud, Mathieu Soutrenon

Concentrated colloidal suspensions of silica particles in polyethylene glycol exhibit a shear thickening behavior: above a critical shear rate in a confined environment, they show a steep increase of viscosity. This reversible transition from a low to a hi ...

A microfluidic process for on-chip formation of assemblies of oxide nanoparticles

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker, Danut Necula

We report the continuous growth of spherical assemblies of silica and titania nanoparticles, which were pre-activated to produce hydroxyl/ peroxy groups on their surface, by flowing a colloid-in-dioctyl phthalate emulsion into a polydimethylsiloxane microf ...

Enhanced tunneling conductivity induced by gelation of attractive colloids

Peter Ryser, Claudio Grimaldi, Francesco Varrato, Giuseppe Foffi, Biagio Nigro

We show that the formation of a gel by conducting colloidal particles leads to a dramatic enhancement in bulk conductivity, due to interparticle electron tunneling, combining predictions from molecular-dynamics simulations with structural measurements in a ...

Multistep kinetic self-assembly of DNA-coated colloids

Francesco Varrato, Giuseppe Foffi

Equilibrium self-assembly relies on the relaxation of disordered mixtures of building blocks towards an ordered ground state. The main drawback of this traditional approach lies in the kinetic traps that often interrupt the progression of the system toward ...

Growth and Alignment of Thin Film Organic Single Crystals from Dewetting Patterns

Roland Hany, Jakob Heier, Gian-Luca Bona, Gaëtan Wicht, Raffaele Mezzenga, Thomas Geiger

Studying and understanding the conditions under which organic semiconductors can be engineered to form aligned single crystals in thin films is of primary importance owing to their unique orientation-dependent optoelectronic properties. Efforts to reach th ...

Single particle detection, manipulation and analysis with resonant optical trapping in photonic crystals

Romuald Houdré, Nicolas Maxime André Descharmes, Ulagalandha Perumal Dharanipathy, Zhaolu Diao, Mario Lucien Henri Tonin

We demonstrate a resonant optical trapping mechanism based on two-dimensional hollow photonic crystal cavities. This approach benefits simultaneously from the resonant nature and unprecedented field overlap with the trapped specimen. The photonic crystal s ...

Inertisation of heavy metals in municipal solid waste incineration fly ash by means of colloidal silica – a synchrotron X-ray diffraction and absorption study

Rudolf Paul Wilhelm Jozef Struis

Many efforts have been undertaken in past decades to minimize pollution from municipal solid waste incineration fly ash (MSWI FA). This residue is toxic, because of its high concentration of heavy metals, mainly Pb and Zn. A new method for heavy metals ent ...
