Melting of nanostructured drugs embedded into a ploymeric matrix

Article Abstract:

The melting behavior of nanostructured organic materials (drugs) embedded into a cross-linked polymeric matrix is studied. The complex microstructure of these nanocomposites, yielded by the polymer matrix in which molecular clusters and nanocrystals of drug plus a cospiquous fraction of water are confined, demanded synergic application of thermal analysis and temperature resolved X-ray diffraction.

Practical applicability of the Jarzynski relation in statistical mechanics: A pedagogical example

Article Abstract:

A simple model of an ideal gas under the piston to gain an insight into the workings of the Jarzynski identity connecting the average exponential of the work over the nonequilibrium trajectories with the equilibrium free energy is discussed. The insight gained from the primitive model found that rapid nonequilibrium measurements are not automatically advantageous.

Resonant nonequilibrium temperatures

Article Abstract:

The nonequilibrium temperatures (NETs) in a two-state system driven to a nonequilibrium steady state by the action of an oscillatory field are investigated. The two-level systems are simple model systems where theoretical predictions for the NETs could be experimentally tested at both qualitative and quantitative levels.
