Rheological Properties of the Reverse Mesophases of the Pluronic L64/P-Xylene/Water System

open access: yesApplied Rheology, 2004
The behaviour of reverse micellar solution and reverse hexagonal and lamellar liquid crystal phases in pluronic L64/water/p-xylene ternary system was investigated by rheological techniques.

Ice crystal characterization in cirrus clouds: a sun-tracking camera system and automated detection algorithm for halo displays [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
Halo displays in the sky contain valuable information about ice crystal shape and orientation: e.g., the 22° halo is produced by randomly oriented hexagonal prisms while parhelia (sundogs) indicate oriented plates.

Multi-Color Luminescence Transition of Upconversion Nanocrystals via Crystal Phase Control with SiO2 for High Temperature Thermal Labels [PDF]

open access: yes, 2020
Upconversion nanocrystals (UCNs)-embedded microarchitectures with luminescence color transition capability and enhanced luminescence intensity under extreme conditions are suitable for developing a robust labeling system in a high-temperature thermal ...

Chiral surfaces self-assembling in one-component systems with isotropic interactions [PDF]

open access: yes, 2012
We show that chiral symmetry can be broken spontaneously in one-component systems with isotropic interactions, i.e. many-particle systems having maximal a priori symmetry.

Hexagonal High-Entropy Alloys

open access: yes, 2014
We report on the discovery of a high-entropy alloy with a hexagonal crystal structure. Equiatomic samples in the alloy system Ho-Dy-Y-Gd-Tb were found to solidify as homogeneous single-phase high-entropy alloys.

On damage tensor in linear anisotropic elasticity [PDF]

open access: yesTheoretical and Applied Mechanics, 2017
In this paper, the anisotropic linear damage mechanics is presented starting from the principle of strain equivalence. The authors have previously derived damage tensor components in terms of elastic parameters of undamaged (virgin) material in closed ...

Maintaining Glycerol-Based Hexagonal Structures by Crosslinkers for High Permeability Nanofiltration

open access: yesCrystals
Hypothesis: Structural optimization of crosslinkers within a reactive glycerol-based hexagonal lyotropic liquid crystal (HLLC) system is proposed to enhance the interfacial stability of hexagonal mesophases and improve the hexagonal structure retention ...
