Large-scale molecular simulations of the elastocaloric effect in swollen monodomain main-chain liquid crystal elastomers are performed, following the so-called ‘indirect approach’ where the magnitude of the effect is extracted from the system’s equation of state connecting stress, strain and tempera ...

A coarse-grained molecular Monte Carlo simulation of the barocaloric effect in a model Gay-Berne liquid crystal is presented, following the so-called indirect approach wherein the caloric response is obtained from thermodynamic arguments applied to the simulated equilibrium relation between pressure ...

V magistrski nalogi se posvetimo modeliranju svetlobno odzivnih tekočekristalnih sistemov, ki vsebujejo derivate azobenzena. Pomembna lastnost azobenzenskih derivatov je trans-cis geometrijska izomerizacija, ki se pojavi ob izpostavitvi UV-svetlobi. S povečanjem koncentracije gradnikov cis v tekočem ...

Tekoči kristali so posebni anizotropni materiali, ki imajo lastnosti tako tekočin kot kristalov, zaradi česar so zanimivi za raziskave in aplikacije, v katerih so pogosto izpostavljeni zunanjemu električnemu ali magnetnemu polju. Njihovo obnašanje postane še bolj kompleksno v ograjenih sistemih, kje ...

We investigate main-chain liquid crystal elastomers (LCEs) formed by photoresponsive azobenzene units with different populations of trans and cis conformers (from fully trans to fully cis). We study their macroscopic properties as well as their molecular organization using extensive Monte Carlo simu ...

In the search for alternative, environmentally friendly refrigeration technologies, caloric effects play an important role. Over the past years, liquid crystals have emerged as promising caloric materials. Here, we present a molecular simulation study of the electrocaloric and magnetocaloric effect ...

We employ Monte Carlo simulations to study the defects occurring in a nematic droplet formed by biaxial molecules. The simulations are carried out using a lattice model based on a dispersive orientational biaxial potential previously employed to establish the rich phase diagram of the system. The fo ...

With the increased environmental awareness, the search for environmentally friendlier heat-management techniques has been the topic of many scientific studies. The caloric materials with large caloric effects, such as the electrocaloric (EC) and elastocaloric (eC) effects, have increased interest du ...
