Polydispersity and the fluid-crystalline phase transition
2014 A « critical » degree of polydispersity is postulated beyond which liquid and crystalline states merge. For a system with a triangular particle-size distribution, the disappearance of the melting transition is estimated to occur at levels of just less than 30 % polydispersity. J.

متن کاملPhase transition of the dry friction between crystalline surfaces induced by normal load
A major source of energy dissipation and surface wear is the kinetic friction at the interfaces of sliding bodies. Traditionally, on a macroscopic scale, this undesirable effect is reduced with lubricating the surfaces by introducing oil into their interface. An interesting phenomenon, called superlubricity, has been reported on a nanometer scale where dry (without lubricant oil) fruition and w...
متن کاملPhase Transitions in Crystalline
Solid polymorphism in five compounds of the type [Me(H20)6](BF4)2 , where Me = Mn, Fe, Co, Ni and Zn, have been studied in the temperature range 120 330 K by DSC. For each substance at least three solid modifications have been found. In addition, for compounds with Me = Mn, Fe and Zn some new low temperature phase transitions have been observed. The transition temperatures for the [Me(H20)6](BF...
متن کاملKinetics of the crystalline-liquid crystalline phase transition of dimyristoyl L-alpha-lecithin bilayers.
Aqueous dispersions of synthetic dimyristoyl L-alpha-lecithin undergo a sharp decrease in turbidity in the temperature range where the crystalline-liquid crystalline phase transition occurs. Equilibrium transition curves, monitored by the absorbancy change at 300 nm, reproduce all the important features of a calorimetric melting curve [Hinz & Sturtevant (1972) J. Biol. Chem. 247, 6071]. A rapid...
متن کاملFerroelectric phase transition in individual single-crystalline BaTiO3 nanowires.
We report scanned probe characterizations of the ferroelectric phase transition in individual barium titanate (BaTiO3) nanowires. Variable-temperature electrostatic force microscopy is used to manipulate, image, and evaluate the diameter-dependent stability of ferroelectric polarizations. These measurements show that the ferroelectric phase transition temperature (TC) is depressed as the nanowi...
