Poling-free spinning process of manufacturing piezoelectric yarns for textile applications

open access: yesMaterials & Design, 2019
This report describes a new twist-spinning process for the manufacture of piezoelectric yarn without the need for additional poling processes. Poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) nanofibers were first electrospun and organized into a ...

Optical twists in phase and amplitude

open access: yesOptics Express, 2011
Light beams with helical phase profile correspond to photons having orbital angular momentum (OAM). A Laguerre-Gaussian (LG) beam is an example where its helical phase sets a phase-singularity at the optical axis and forms a ring-shaped transverse amplitude profile.

Chemical-Physical Characterization of a Binary Mixture of a Twist Bend Nematic Liquid Crystal with a Smectogen

open access: yesCrystals, 2020
Nematic twist-bend phases (NTB) are new types of nematic liquid crystalline phases with attractive properties for future electro-optic applications. However, most of these states are monotropic or are stable only in a narrow high temperature range.

Twist Elasticity and Anchoring in a Lamellar Nematic Phase [PDF]

open access: yesPhysical Review Letters, 2004
Electro-optic measurements were performed on a lamellar nematic phase in which the mesogenic moieties lie in lamellae that are separated by partially perfluorinated side groups. The twist elastic constant K22, viscosity gamma(1), and the quadratic and quartic anchoring strength coefficients are reported.

Equilibrium phase diagram and thermal responses of charged DNA-virus rod-suspensions at low ionic strengths

open access: yesScientific Reports, 2021
The collective behavior of DNA is important for exploring new types of bacteria in the means of detection, which is greatly interested in the understanding of interactions between DNAs in living systems.

Twist grain boundaries in cubic surfactant phases [PDF]

open access: yesThe Journal of Chemical Physics, 2009
Twist grain boundaries in bicontinuous cubic surfactant phases are studied by employing a Ginzburg–Landau model of ternary amphiphilic systems. Calculations are performed on a discrete real-space lattice with periodic boundary conditions for the lamellar Lα, gyroid G, diamond D, and the Schwarz P phases for various twist angles.

Localization Detection Based on Quantum Dynamics

open access: yesEntropy, 2022
Detecting many-body localization (MBL) typically requires the calculation of high-energy eigenstates using numerical approaches. This study investigates methods that assume the use of a quantum device to detect disorder-induced localization.

Statistical Characteristics of a Twisted Anisotropic Gaussian Schell-Model Beam in Turbulent Ocean

open access: yesPhotonics, 2020
The analytical expression of the cross-spectral density function of a twisted anisotropic Gaussian Schell-model (TAGSM) beam transmitting in turbulent ocean is derived by applying a tensor method.

Optimal Segment Control of Active Twist Rotor for Power Reduction in Forward Flight

open access: yesApplied Sciences, 2021
The segment control of active twist rotor is investigated to evaluate the effectiveness in rotor power reduction. A numerical model for predicting the isolated rotor power and loads in steady level flights is deployed and validated. A parametric sweep of
