SummaryA model for the orientational-order parameter in liquid crystals from the microscopic viewpoint and in conformity with its current understanding well established in the field of phase transitions is proposed here. This model has a close resemblance with the original ideas of Maier and Saupe. However, it is independent of the nature of molecules, rigid or flexible, and enables us to describe a phase with a single-order parameter tensor $$\mathop S\limits^ \leftrightarrow$$ as expected… 
Orientational order of uniaxial nematic liquid crystals using electron spin resonance of solute molecules
SummaryWe present here measurements of hyperfine splittings andg factors of two nitroxide spin probes dissolved inp-azoxyanisole, a wellknown uniaxial nematic liquid crystal, about one part to a
Relation between orientational order parameters of matrix and probe in nematic liquid crystals
SummaryThe phenomenological relation between the orientational order parameters of matrix (S) and probe (Sp) has been obtained and confirmed for a large number of impure nematic liquid cyrstals. The
Short and soft: multi-domain organization, tunable dynamics and jamming in suspensions of grafted colloidal cylinders with small aspect ratio.
TLDR
These properties set short and soft nanocylinders apart from long colloidal rods (with large aspect ratio) and provide insights for fundamentally understanding the physics in this intermediate soft colloidal regime, as well as and for tailoring the flow properties of non-spherical soft colloids.
RECENT CHARACTERIZATION AND APPLICABILITY OF POLYMORPHISM: LIQUID CRYSTAL
Liquid crystals (LCs) are a state of matter that has properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may
Cooperative Ordering and Kinetics of Cellulose Nanocrystal Alignment in a Magnetic Field.
TLDR
The effects of comparatively weak magnetic fields and CNC concentration and kinetics and degree of CNC ordering are investigated using small-angle X-ray scattering using sigmoidal profile to showcase the drastic effects of relativelyWeak magnetic fields on CNC alignment.
The molecular configuration of a DOPA/ST monolayer at the air-water interface: a molecular dynamics study.
TLDR
Hydrogen bonds, due to the presence of the amide group in DOPA, are the cause of the disorder in its Langmuir monolayers, and the conclusion may be helpful in making ordered organic monolayer in the future.
Probing the structure and dynamics of confined water in AOT reverse micelles.
TLDR
The resulting structures and dynamics are found to depend more on the force field used than on varying interpretations of the water:surfactant ratio in terms of absolute size of the reverse micelle.

TLDR
Crystallinity analysis suggests that more ordered P3HT is observed near the interface for face-on and amorphous case, while no such trend is observed for edge- on and end-on configurations due to weaker interactions at the interface as evident from the considerably less negative interfacial energy.
Anisotropic Thermal Interface Materials: Directional Heat Transfer in Uniaxially Oriented Liquid Crystal Networks.
TLDR
The newly developed TCLC film can be used as a TIM between a high-power light-emitting diode and a heat sink and show the outstanding thermal conductivity of 1.21 W/m K, which is higher than conventional organic materials.
