Antiferroelectric Smectic Ordering as a Prelude to the Ferroelectric Nematic:Introducing the Smectic Phase
Xi Chen, Vikina Martinez, Eva Korblova +9
We have structurally characterized the liquid crystal phase that appears as an intermediate state when a dielectric nematic, having polar disorder of its molecular dipoles, transit…
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…
Identification of New Assembly Mode in the Heliconical Nematic Phase via Tender Resonant X-ray Scattering
Yu Cao, Jun Feng, Asritha Nallapaneni +5
Helical structures are exciting and are utilized in numerous applications ranging from biotechnology to displays to medicine. Accurate description and understanding of resonance ef…
Multi-level Chirality in Liquid Crystals Formed by Achiral Molecules
Mirosław Salamończyk, Nataša Vaupotič, Damian Pociecha +6
In many biological materials with a hierarchical structure there is an intriguing and unique mechanism responsible for the 'propagation' of order from the molecular to the nano- or…
Distinct differences in the nanoscale behaviors of the twist-bend liquid crystal phase of a flexible linear trimer and homologous dimer
Michael R. Tuchband, Daniel A. Paterson, Mirosław Salamończyk +12
We synthesized the liquid crystal dimer and trimer members of a series of flexible linear oligomers and characterized their microscopic and nanoscopic properties using resonant sof…
Heliconical smectic phases formed by achiral molecules
Jordan P. Abberley, Ross Killah, Rebecca Walker +6
A series of asymmetric dimers with an odd number of atoms in the spacer were found to form different types of twisted structures despite being achiral. The formation of a variety o…
Structure of nanoscale-pitch helical phases: blue phase and twist-bend nematic phase resolved by resonant soft X-ray scattering
Mirosław Salamończyk, Nataša Vaupotič, Damian Pociecha +3
Periodic structures of phases with orientational order of molecules, but homogenous electron density distribution: a short pitch cholesteric, blue phase and twist-bend nematic phas…
Double-Helical Tiled Chain Structure of the Twist-Bend Liquid Crystal phase in CB7CB
Michael R. Tuchband, Min Shuai, Keri A. Graber +16
The twist-bend nematic liquid crystal phase is a three-dimensional fluid in which achiral bent molecules spontaneously form an orientationally ordered macroscopically chiral helico…
Interaction of Molecular Oxygen with Hexagonally Reconstructed Au (001) Surface
Andrew Loheac, Andi Barbour, Vladimir Komanicky +6
Kinetics of molecular oxygen / Au (001) surface interaction has been studied at high temperature and near atmospheric pressures of O2 gas with in situ x-ray scattering measurements…
Resonant carbon K-edge soft x-ray scattering from lattice-free heliconical molecular ordering: soft dilative elasticity of the twist-bend liquid crystal phase
Chenhui Zhu, Michael R. Tuchband, Anthony Young +7
Resonant x-ray scattering shows that the bulk structure of the twist-bend liquid crystal phase, recently discovered in bent molecular dimers, has spatial periodicity without electr…
High On/Off Ratio Memristive Switching of Manganite-Cuprate Bilayer by Interfacial Magnetoelectricity
Xiao Shen, Timothy J. Pennycook, David Hernandez-Martin +7
Memristive switching serves as the basis for a new generation of electronic devices. Memristors are two-terminal devices in which the current is turned on and off by redistributing…
Dynamics of Au (001) Surface in Electrolytes: In-Situ Coherent X-ray Scattering and Scanning Tunneling Microscopy
M. S. Pierce, V. Komanicky, A. Barbour +5
We studied dynamics of Au (001) surface in situ in 0.1 M HClO4 electrolyte solution using both coherent x-ray scattering and scanning tunneling microscopy (STM). The surface of Au…
