Phase Transitions in Interlamellar Films

Phase transitions in argon films.

We present heat-capacity data detailing the evolution of the first six layers of argon adsorbed on graphite foam. The second and third layers have liquid-solid-gas triple points similar to the first layer. These layers exhibit a phase diagram consisting of two-dimensional solid, liquid, and gas phases on top of a solid film. Above the temperatures of the individual-layer triple points, the melt...

Phase Transitions in Mesoscopic Superconducting Films

We solve the Ginzburg-Landau equation (GLE) for the mesoscopic superconducting thin film of the square shape in the magnetic field for the wide range of the Ginzburg-Landau parameter 0.05 < κeff < ∞. We found that the phase with the antivortex exists in the broad range of parameters. When the coherence length decreases the topological phase transition to the phase with the same total vorticity ...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...

Topological Phase Transitions in Periodically Modulated Quantized Metal Films

Nanoparticle-Induced Phase Transitions in Diblock-Copolymer Films

Incorporation of nanoparticles into self-assembled block copolymers has been explored as an efficient way for improving the mechanical strength, electrical conductivity, and optical properties of materials at the nanometer scale. Recent computer simulations predict that the cooperative self-organization of nanoparticles and block copolymers should yield a wide variety of structures with well-co...
