Phase diagram for sodium clusters

Size-temperature phase diagram for small Lennard-Jones clusters.

The size-temperature "phase diagram" for small Lennard-Jones clusters LJn (n< or =147) is constructed based on the analysis of the heat capacities Cv(T) , computed by the parallel tempering Monte Carlo method. Two types of "phase transitions" are often observed: the higher-temperature solid-liquid transition, due to melting of the cluster core, and the lower-temperature melting that occurs with...

Phase diagram of microtubules.

The protein tubulin is found in every cell of every living organism (with the exception of bacteria ) [1]. In the presence of guanosine-tri-phosphate (GTP) and magnesium ions (Mg +), tubulin-GTP complexes form [2] and aggregate [3] into long, hollow cylinders called microtu bules. Microtubules are about 25 nm in outer diameter, incorporate 1625 tubulin dimers per micrometer of their length [4] ...

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...

Multilayer krypton phase diagram.

We present vapor pressure and high-resolution heat-capacity measurements of multilayer krypton films adsorbed on graphite. We have found a complex phase diagram including reentrant layering transitions for coverages higher than three layers. The third layering transition does not end in a condensation critical point as was previously expected. The second-layer melting transition is preceded by ...
