Frustration of crystallisation by a liquid–crystal phase [PDF]

open access: yes, 2017
Frustration of crystallisation by locally favoured structures is critically important in linking the phenomena of supercooling, glass formation, and liquid-liquid transitions.

ZnO1−xSx Nanosphere in Ferroelectric Liquid Crystal Matrix: The Effect of Aggregation and Defects on the Dielectric and Electro-Optical Properties

open access: yesAdvances in Condensed Matter Physics, 2013
High concentration (5 wt %) of ZnO1−xSx nanosphere (NS) has been dispersed in the ferroelectric liquid crystal (FLC) to analyze the effect of high dopant concentration in the FLC matrix. The FLC molecules actively interact with the NS. The presence of NS

Simultaneously enhancing the electronic and ionic conductivities of Li2ZnTi3O8 via modification with polyacrylonitrile-derived carbon for high-performance anodes

open access: yesChemPhysMater, 2023
Polyacrylonitrile (PAN) with C≡N bonds can be converted to nitrogen-doped carbon during carbonization, which enhances electronic conductivity by compensating for the deficiency of the Li2ZnTi3O8 (LZTO) anode.

Tunability of wire-grid metamaterial immersed into nematic liquid crystal [PDF]

open access: yes, 2007
We propose electrically tunable hybrid metamaterial consisting of special wire grid immersed into nematic liquid crystal. The plasma-like permittivity of the structure can be substantially varied due to switching of the liquid crystal alignment by ...

Liquid-crystal photonic applications [PDF]

open access: yes, 2011
Liquid crystals are nowadays widely used in all types of display applications. However their unique electro-optic properties also make them a suitable material for nondisplay applications. We will focus on the use of liquid crystals in different photonic

A uniqueness and regularity criterion for Q-tensor models with Neumann boundary conditions [PDF]

open access: yes, 2014
We give a regularity criterion for a $Q$-tensor system modeling a nematic Liquid Crystal, under homogeneous Neumann boundary conditions for the tensor $Q$.

Critical points and symmetries of a free energy function for biaxial nematic liquid crystals [PDF]

open access: yes, 2014
We describe a general model for the free energy function for a homogeneous medium of mutually interacting molecules, based on the formalism for a biaxial nematic liquid crystal set out by Katriel {\em et al.} (1986) in an influential paper in {\em Liquid

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Negative Dielectric Anisotropy Liquid Crystal with Improved Photo-Stability, Anti-Flicker, and Transmittance for 8K Display Applications

open access: yesMolecules, 2022
Video systems such as 8K displays can provide a strong sense of presence and reality due to their extremely high resolution and wide field of view. However, high-resolution displays generally suffer from reduced transmittance, which requires the use of ...
