Temperature variation experiments of small angle neutron scattering ~SANS! and neutron spin echo ~NSE! were carried out in order to compare effects of temperature and pressure on a structural formation in a ternary microemulsion system composed of AOT ~Aerosol-OT; dioctyl sulfosuccinate sodium salt!, D2O, and n-decane. From SANS measurements, a phase transition from one-phase dense water-in-oil...

The PZT material near the morphotropic phase boundary where a monoclinic phase was observed is studied in this paper. A theory of the tetragonal to monoclinic phase transition was developed within the Landau free energy approach. The order parameter is the electric polarization vector. The phase transition from the tetragonal to the monoclinic phase is of the first order near the second order. ...

In order to fabrication of transparent glass-ceramics with Li-mica nano crystals, the glasses with chemical composition of 94.9 mass% Li(1+x)Mg3AlSi3(1+x)F2 (x=0.5) with 5.1 mass% MgF2 were crystallized. The glasses were fabricated via the conventional melt-quenching technique. Mica crystals were precipitated in the glass phase by later heat treatment. Glass samples had glass transition tempera...

Quantum Chromodynamics (QCD) is believed to undergo phase transitions from hadronic matter to a quark-gluon plasma (QGP) at high temperature. The QGP phase transitions can consist of two distinct transitions – the deconfinement transition and the chiral phase transition. Several theoretical studies [1] have clarified that confinement would be closely related to chiral dynamics and the confined ...

dl-Norvaline is a molecular crystal at room temperature and it undergoes a phase transition when cooled below 190 K. This phase transition is believed to be Martensitic, thus making it of particular interest for molecular machines. In this paper we investigate this phase transition by measuring its terahertz (THz) spectrum over a range of temperatures. Temperature-dependent THz time-domain spec...

   In this study, effect of asymmetric functionalized graphene oxide (Janus GO) on Young′s modulus and glass transition temperature of Polysulfone (PSf) ultrafiltration membranes was investigated. The membranes were prepared via phase inversion method and GO nanosheets were dispersed in casting solution by sonication. Results showed that the Normalized Young’s modulus (on the basis of neat ...

For realistic values of the Higgs boson mass the high temperature electroweak phase transition cannot be described perturbatively. The symmetric phase is governed by a strongly interacting SU (2) gauge theory. Typical masses of excitations and scales of condensates are set by the " high temperature confinement scale " ≈ 0.2 T. For a Higgs boson mass around 100 GeV or above all aspects of the ph...

A pre-annealing atmospheric pulsed laser exposure was applied to decrease the phase transition (from chemically disordered A1 phase to chemically ordered L10 phase) temperature of FePt nano-particles on a Si (100) substrate. Different pre-annealing laser energy densities of 0.024 and 0.079 J/cm were utilized to expose the pulsed laser deposition (PLD) FePt thin film samples under atmospheric co...

Electron paramagnetic resonance (EPR) and differential scanning calorimetry (DSC) have been used to study the effect on the phase transition of dimyristoylphosphatidylcholine membranes of incorporating various stearic acid spin labels (SASL's) that contain the bulky oxazolidine ring at various positions along the stearyl chain. SASL's lowered the phase transition temperature and decreased the s...
