Shear-induced collapse of the dilute lamellar phase

Physical Review Letters, 1992
I show that a dilute, sterically stabilized lyotropic smectic liquid crystal, subjected to a sufficiently large velocity gradient in the plane of the layers, will undergo a phase separation, with regions of reduced layer spacing coexisting with regions devoid of any layer material.

Phase diagrams for correlated dilution problems

Journal of Physics C: Solid State Physics, 1988
The authors study spins with correlated ('bootstrap') dilution in which a (randomly occupied) site only develops a magnetic moment if surrounded by at least m magnetic neighbours. A generalisation of the Harris criterion indicates that the tendency of correlated disorder is to favour a new critical behaviour upon dilution.

Phase Transition of Diluted Magnetic Semiconductor

AIP Conference Proceedings, 2011
Three types of phase transitions in diluted magnetic semiconductor, first‐order, second‐order and mixed‐order, are found in theory. Especially the mixed type transition shows two steps transition and novel specific heat property. Specific heat properties disclose a possible meta ferromagnetic phase confirmed by the experimental qualitative result.

PHASE DIAGRAM OF A DILUTE BINARY SYSTEM

International Journal of Modern Physics C, 1992
Phase diagram of a binary system with quenched impurities has been studied with Monte Carlo computer simulation technique. Use of Swendsen-Wang algorithm makes it possi-ble to explore the vicinity of percolation transition which was difficult to explore with the traditional Metropolis method.

Phase diagrams of dilute Ising antiferromagnets

Journal of Physics: Condensed Matter, 1989
Using the Monte Carlo technique the phase diagram of dilute Ising antiferromagnets in a field is found to be non-universal. Depending on the values of both the dilution and ratio of next-nearest-to nearest-neighbour interactions, the transition from the disordered phase as a function of the field can either be always continuous, or first order with a ...

Effect of Shear on Dilute Sponge Phase

Langmuir, 1995
Although lyotropic sponge phases are isotropic multiconnected membrane systems, these phases present a strong flow birefringence upon shaking them. In this brief report we investigate this effect and present data allowing determination of a characteristic frequency which seems to be related to the fusion time of the ...

Phase Behavior of an Extended Surfactant in Water and a Detailed Characterization of the Dilute and Semidilute Phases

Langmuir, 2009
The formation of microemulsions with triglycerides under ambient conditions has been a challenge for scientists for many decades. For this reason, so-called extended surfactants were developed that contained hydrophilic/lipophilic linkers to stretch further into the oil and water phase, and enhance the solubility of triglycerides in water.

CSR Phase Space Dilution in CBETA

2019
CBETA, the Cornell BNL ERL Test Accelerator, will be the first multi-turn Energy Recovery Linac (ERL) with SRF accelerating cavities and Fixed Field Alternating gradient (FFA) beamline. While CBETA gives promise to deliver unprecedentedly high beam current with simultaneously small emittance, Coherent Synchrotron Radiation (CSR) can pose detrimental ...

Phase diagram and dilution experiments in the crystallization of carboxypeptidase G2

Acta Crystallographica Section D Biological Crystallography, 1994
The automated microbatch technique developed at Imperial College has been used to establish a phase diagram for crystallization. The concentrations of the protein (carboxypeptidase G2) and precipitant (PEG 4000) were varied, while pH and temperature were kept constant.
