Hydrodynamic Mechanism of Colloidal Propulsion through Momentum Exchange
Javier Diaz, Ignacio Pagonabarraga, Carles Calero
Propulsion of colloidal particles due to momentum transfer from localized surface reactions is investigated by solving the exact unsteady Stokes equation. We model the effect of su…
Active droplets controlled by enzymatic reactions
Jacques Fries, Javier Diaz, Marie Jardat +3
The formation of condensates is now considered as a major organization principle of eukaryotic cells. Several studies have recently shown that the properties of these condensates a…
Active particles confined in deformable droplets
Javier Diaz, Ignacio Pagonabarraga
Active particles under soft confinement such as droplets or vesicles present intriguing phenomena, as collective motion emerges alongside the deformation of the environment. A mode…
Activity-driven emulsification of phase-separating binary mixtures
Javier Diaz, Ignacio Pagonabarraga
Systems containing active components are intrinsically out of equilibrium, while binary mixtures reach their equilibrium configuration when complete phase separation is achieved. A…
Phase behaviour of active particles in block copolymer melts
Javier Diaz, Ignacio Pagonabarraga
Block copolymer melts offer a unique template to control the position and alignment of nanoparticles due to their ability to self-assemble into periodic ordered structures. Active…
Block copolymer-nanorod co-assembly in thin films: effects of rod-rod interaction and confinement
Javier Diaz, Marco Pinna, Andrei V. Zvelindovsky +2
Simulations and experiments of nanorods (NRs) show that co-assembly with block copolymer (BCP) melts leads to the formation of a superstructure of side-to-side NRs perpendicular to…
Phase Behavior of Block Copolymer Nanocomposite Systems
Javier Diaz, Marco Pinna, Andrei V. Zvelindovsky +1
Nanocomposite materials made of block copolymer and nanoparticles display properties which can be different from the purely polymeric matrix. The resulting material is a crossover…
Large scale three dimensional simulations of hybrid block copolymer/nanoparticle systems
Javier Diaz, Marco Pinna, Andrei V. Zvelindovsky +1
Block copolymer melts self-assemble in the bulk into a variety of nanostructures, making them perfect candidates to template the position of nanoparticles. The morphological change…
Non-spherical nanoparticles in block copolymer composites: nanosquares, nanorods and diamonds
Javier Diaz, Marco Pinna, Andrei V. Zvelindovsky +1
A hybrid block copolymer(BCP) nanocomposite computational model is proposed to study nanoparticles(NPs) with a generalised shape including squares, rectangles and rhombus. Simulati…
Co-assembly of Janus nanoparticles in block copolymer systems
Javier Diaz, Marco Pinna, Andrei Zvelindovsky +1
Block copolymer are ideal matrices to control the localisation of colloids. Furthermore, anisotropic nanoparticles such as Janus nanoparticles possess an additional orientational d…
Cell Dynamic Simulations of Diblock Copolymer/Colloid Systems
Javier Diaz, Marco Pinna, Andrei Zvelindovsky +2
The presence of nanoparticles in a diblock copolymer leads to changes in the morphology and properties of the matrix and can produce highly organized hybrid materials. The resultin…
