Shear-mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals
Péter Salamon, Marcell Tibor Máthé, Hiroya Nishikawa +2
Piezoelectricity (linear coupling between mechanical deformation and electric signal) was originally observed only in solid crystals. Recently, it was discovered that liquid ferroe…
Electrochromic chiral ferroelectric nematic liquid crystals
Md Sakhawat Hossain Himel, James T. Gleeson, Robert J. Twieg +2
Chiral nematic liquid crystals are one-dimensional photonic band-gap materials whose reflection wavelength can be well tuned by temperature, but only limited and irreversible tunin…
Low-Power Temperature Control by Chiral Ferroelectric Nematic Liquid Crystal Windows
Md Sakhawat Hossain Himel, Rohan Dharmarathna, Netra Prasad Dhakal +5
Low power consumption is critical for smart windows for temperature control and privacy. The recently discovered ferroelectric nematic liquid crystals exhibit strong coupling of th…
Shape Changes of Liquid Crystal Elastomers Swollen by Low Molecular Weight Liquid Crystal Drops
Mahesha Kodithuwakku Arachchige, Rohan Dharmarathna, Paul Fleischer +1
An elastomer swelling actuator deforms by absorbing a fluid, thus generating mechanical movement. We show that depositing small droplets of low molecular weight liquid crystal on l…
Director-layer dynamics in the antiferroelectric smectic-ZA phase of a ferroelectric nematic liquid crystal
Arjun Ghimire, Bijaya Basnet, Hao Wang +7
A dynamic light scattering study of director-layer fluctuations in the antiferroelectric smectic-ZA phase of the ferroelectric nematic liquid crystal DIO is reported. The dynamics…
Directional Swimming of B. Subtilis Bacteria Near a Switchable Polar Surface
Mahesha Kodithuwakku Arachchige, Zakaria Siddiquee, Hend Baza +3
The dynamics of swimming bacteria depend on the properties of their habitat media. Recently it was shown that the motion of swimming bacteria dispersed directly in a non-toxic wate…
Dielectric properties of a ferroelectric nematic material: quantitative test of the polarization-capacitance Goldstone mode
Alex Adaka, Mojtaba Rajabi, Nilanthi Haputhantrige +3
The recently discovered ferroelectric nematic (NF) liquid crystals (LC) have been reported to show an extraordinarily large value of the real part of the dielectric constant at low…
Ferroelectric Nematic Droplets in their Isotropic Melt
Kelum Perera, Rony Saha Pawan Nepal, Rohan Dharmarathna +6
The isotropic to ferroelectric nematic liquid transition had been theoretically studied over one hundred years ago, but its experimental studies are rare. Here we present polarizin…
The interplay between spatial and heliconical bond order in twist-bend nematic materials
Rony Saha, Chenrun Feng, Chris Welch +6
The nanostructure of two novel sulfur containing dimer materials has been investigated experimentally by hard and by resonant tender X-ray scattering techniques. On cooling the dim…
Light scattering study of the "pseudo-layer" compression elastic constant in a twist-bend nematic liquid crystal
Z. Parsouzi, Shokir A. Pardaev, C. Welch +9
The nematic twist-bend (TB) phase, exhibited by certain achiral thermotropic liquid crystalline (LC) dimers, features a nanometer-scale, heliconical rotation of the average molecul…
Second harmonic light scattering induced by defects in the twist-bend nematic phase of liquid crystal dimers
Shokir A. Pardaev, S. M. Shamid, M. G. Tamba +8
The nematic twist-bend () phase, exhibited by certain thermotropic liquid crystalline (LC) dimers, represents a new orientationally ordered mesophase -- the first…
Anomalous increase in nematic-isotropic transition temperature in dimer molecules induced by magnetic field
S. M. Salili, M. G. Tamba, S. N. Sprunt +4
We have determined the nematic-isotropic transition temperature as a function of applied magnetic field in three different thermotropic liquid crystalline dimers. These molecules a…
