Lyotropic phase behavior of the nonionic and the half-ionized oleyldimethylamine oxide (OlDMAO)/water systems was investigated using polarized light micros...
A theory of the reorientational phase transition in the biaxial surface layer of a lyotropic liquid crystal is proposed. The transition is induced by the c...
We present a new colloidal composite formed by combining polymer-magnetite nanoparticles and a lyotropic nematic liquid crystals. TEM investigations on the ...
We studied the photonic effect in a hyper-swollen lyotropic lamellar phase. This system is composed of only a small percentage of amphiphilic molecules and...
The Onsager virial approximation for the isotropic -nematic transition of thin rodlike particles is extended to semiflexible polymers and liquid crystal density. Theories for the orientational entropy and excluded volume interaction for ...

We develop a model for gels and entangled solutions of semiflexible biopolymers such as F-actin. Such networks play a crucial structural role in the cytosk...
High molecular weight copolyesters were prepared by the acidolysis of poly(ethylene terephthalate) with p -acetoxybenzoic acid and polycondensation through the acetate and carboxyl groups. The mechanical properties of the injection-mold...
The DNA molecule is extremely compacted in bacteria, in cell nuclei, sperm heads and virus capsids. These interactions between DNA molecules are important ...
The phase diagram of a system of hard parallel spherocylinders with length-to-width ratios L/D between 0 and ∞ is investigated by Monte Carlo simulation. ...
We report a computer-simulation study of the phase diagram of a system of hard spherocylinders with aspect ratio L/D between 0 and 5. For L/D≤3 only isotr...
A density-functional theory, based on the smoothed density approximation, is presented in order to study phase transitions in systems of hard spherocylinde...
We propose a universal approximate method which enables us to study the statistical mechanics of the liquid-crystalline ordering in the solutions of stiffchain macromolecules with limited flexibility of arbitrary nature at arbitrary solu...
The liquid-solid transition is found by calculating the thermodynamic potential of a dense classical system as a function of order parameters which are pro...
The interactions between mesophase-forming copolymers and nanoscopic particles can lead to highly organized hybrid materials. The morphology of such compos...
We present a review of recent advances in the statistical associating fluid theory (SAFT). In contrast to the "chemical theory", in which nonideality is explained in terms of chemical reactions between the species, SAFT and similar appro...
We introduce a simulation technique for creating dense random packings of hard particles. The technique is particularly suited to handle particles of diffe...
Uniform, large aspect-ratio, monocrystalline BaWO4 nanorods were synthesized using a reversed micelle templating method; novel nanorod superstructures were observed in both as-made materials and Langmuir–Blodgett monolayer assemblies.
The color of colloidal dispersions of gold particles in a fluid, typically water, varies from red to blue, depending upon the shape and size of particles. ...
Aqueous suspensions of goethite (alpha-FeOOH) nanorods form a mineral lyotropic nematic phase that aligns in a very low magnetic field (20 mT for samples 2...
We report measurements of the cholesteric pitch and twist elastic constant (K-22) in monodisperse suspensions of the rodlike virus filamentous bacteriophag...
Alignment of macromolecules in nearly neutral aqueous lyotropic liquid-crystalline media such as bicelles, commonly used in macromolecular NMR studies, can...
Using isobaric semigrand Monte Carlo simulations, we have investigated the phase behavior of a model for polydisperse rodlike colloids. The system consists...
At volume fractions larger than 8.5%, aqueous suspensions of lath-like goethite (alpha-FeOOH) nanorods form a lyotropic nematic phase. In this article, we ...
