Micellar Mimicry of Intermetallic C14 and C15 Laves Phases by Aqueous Lyotropic Self-Assembly

The effect of molecular self-diffusion on NMR linewidth and relaxation in micellar lyotropic phases

2014 The effect of molecular translational diffusion on the NMR linewidth and relaxation in lyotropic systems with finite aggregates has been studied. Here the molecular rotation induced by the translational motion of the molecule along a curved surface strongly modulates the intramolecular dipolar coupling. The corresponding autocorrelation functions are evaluated for rigid spherical, cylindri...

The effect of alloying on the properties of (Nb,Ti)Cr2 C15 Laves phases

The effect of composition on the ternary (NbCr2–TiCr2) C15 phase properties has been investigated, focusing upon the defect structure, elastic properties, and mechanical behavior. The C15 phase field is continuous between NbCr2–TiCr2, with a maximum phase field width of at least 7 at.% solubility. The defect mechanism is governed by anti-site constitutional defects for all alloys. Mechanically,...

Self-Assembly, Condensation, and Order in Aqueous Lyotropic Chromonic Liquid Crystals Crowded With Additives

Dense multicomponent systems with macromolecules and small solutes attract a broad research interest as they mimic the molecularly crowded cellular interiors. The additives can condense and align the macromolecules, but they do not change the degree of covalent polymerization. We chose a lyotropic chromonic liquid crystal with reversibly and non-covalently assembled aggregates as a much softer ...

Self-assembly in Lyotropic Chromonic Liquid Crystals

We have developed a class of idealized models of chromonic molecules which are miscible in water, but which can form aggregates which in turn organize into lyotropic liquid crystal (LC) phases. By carrying out Monte Carlo simulation in a binary mixture of model chromonic and water molecules, we have studied the effect of concentration and molecular shape on the nature of resulting mesophases.
