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…
