1. Non-equilibrium thermodynamics at the microscopic scales
Sammanfattning : An inherent feature of small systems in contact with thermal reservoirs, be it a pollen grain in water, or an active microbe flagellum, is fluctuations. Even with advanced microscopic techniques, distinguishing active, non-equilibrium processes defined by a constant dissipation of energy to the environment from passive, equilibrium processes is a very challenging task and a vastly developing field of research.

2. Finite-time non-equilibrium thermodynamics of a colloidal particle
Sammanfattning : In this thesis we have thermodynamically characterized finite time processes performed on a colloidal particle, kept in contact with thermal reservoir(s). Thermodynamic processes are implemented on the colloidal particle by systematically changing the confining potential in a time dependent way, according to an external driving protocol or by controlling the environmental conditions over a finite duration.

4. Magnetic materials with tunable thermal, electrical, and dynamic properties : An experimental study of magnetocaloric, multiferroic, and spin-glass materials
Sammanfattning : This thesis concerns and combines the results of experimental studies of magnetocaloric, multiferroic and spin-glass materials, using SQUID magnetometry as the main characteriza-tion technique. The magnetocaloric effect offers an interesting new technology for cooling and heating applications. LÄS MER
5. Mathematical modelling of biomass thermal degradation in a fixed bed reactor
Sammanfattning : A mathematical model of biomass thermal degradation in afixed bed has been developed. Theoretical analysis of drying,pyrolysis and char combustion has been carried out. LÄS MER
