Melting of a skyrmion lattice to a skyrmion liquid via a hexatic phase

Henrik Moodysson Rønnow, Arnaud Magrez, Marco Cantoni, Fabrizio Carbone, Ping Huang, Thomas Schönenberger

While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid ...

Unravelling the role of phoretic and hydrodynamic interactions in active colloidal suspensions

Ignacio Pagonabarraga Mora

Active fluids comprise a variety of systems composed of elements immersed in a fluid environment which can convert some form of energy into directed motion; as such they are intrinsically out-of-equilibrium in the absence of any external force. A fundament ...

Electrochemical Co-Deposition of Gold and Carbon Nanocapsules from a Colloidal Suspension

Stefano Mischler

This paper shows the preparation of a gold suspension containing carbon nanocapsules and their co-deposition from the colloidal galvanic bath on a nickel electrode to obtain gold/nanocapsules composite coatings. The incorporation of the nanocapsules was co ...

Stable Ultraconcentrated and Ultradilute Colloids of CsPbX3 (X = Cl, Br) Nanocrystals Using Natural Lecithin as a Capping Ligand

Francesco Stellacci, Quy Ong Khac

Attaining thermodynamic stability of colloids in a broad range of concentrations has long been a major thrust in the field of colloidal ligand-capped semiconductor nanocrystals (NCs). This challenge is particularly pressing for the novel NCs of cesium lead ...

Effect of surface modification of colloidal silica nanoparticles on the rigid amorphous fraction and mechanical properties of amorphous polyurethane-urea-silica nanocomposites

John Christopher Plummer, Nicolas Candau, Oguzhan Oguz, Stéphane Henri Florian Bernhard

Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt % (4.4 vol %) in order to investig ...
