Entropy controlled phase transitions
A fundamental part of the design of new materials lies in the study and control of the phase transitions of solids. This control implies tweaking the free energies of the different phases of the material, in order to stabilize those we are interested in or destabilize those we are not. Although c...

description |
A fundamental part of the design of new materials lies in the study and control
of the phase transitions of solids. This control implies tweaking the free energies
of the different phases of the material, in order to stabilize those we are interested
in or destabilize those we are not. Although classically it has been understood
that the formation of new solids is driven by enthalpic factors, entropy supposes
a new and promising tool in the field. This kind of approach offers us a simpler
design of assembly particles and a more reliable process. In this thesis we study the
effect entropy can have in the self-assembly of colloids, by applying this approach
to two experimental colloidal systems (mDNACCs and 2D hard spheres), as well
as presenting a new computational method designed for the study of the assembly of spherical colloids. |
