Softness suppresses fivefold symmetry and enhances crystallization of binary Laves phases in nearly hard spheres
Tonnishtha Dasgupta, Gabriele M. Coli, Marjolein Dijkstra
Colloidal crystals with a diamond and pyrochlore structure display wide photonic band gaps at low refractive index contrasts. However, these low-coordinated and open structures are…
Binary icosahedral quasicrystals of hard spheres in spherical confinement
Da Wang, Tonnishtha Dasgupta, Ernest B. van der Wee +8
The influence of geometry on the local and global packing of particles is important to many fundamental and applied research themes such as the structure and stability of liquids,…
Stabilizing the Hexagonal Close Packed Structure of Hard Spheres with Polymers : Phase diagram, Structure, and Dynamics
John R Edison, Tonnishtha Dasgupta, Marjolein Dijkstra
We study the phase behaviour of a binary mixture of colloidal hard spheres and freely-jointed chains of beads using Monte Carlo simulations. Recently Panagiotopoulos and coworkers…
Fabrication of colloidal Laves phases via hard tetramers and hard spheres: bulk phase diagram and sedimentation behaviour
Guido Avvisati, Tonnishtha Dasgupta, Marjolein Dijkstra
Colloidal photonic crystals display peculiar optical properties which make them particularly suitable for application in different fields. However, the low packing fraction of the…
