The properties of isolated chiral skyrmions in thin magnetic films

New Journal of Physics, 2016
Axisymmetric solitonic states ( chiral skyrmions ) were first predicted theoretically more than two decades ago. However, until recently they have been observed in a form of skyrmionic condensates (hexagonal lattices and other mesophases).

8-Methyl-5-methylene-2-oxotricyclo[5.3.1.13,9]dodecan-endo-8-ol

Acta Crystallographica Section E, 2008
The title compound, C14H20O2, crystallizes with homochiral chains of molecules hydrogen bonded together along the b axis. Adjacent chains in the ab plane contain molecules of the same chirality, leading to a chiral segregation of the molecules into ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Chiral gypsum with high‐performance mechanical properties induced by self‐assembly of chiral amino acid on an amorphous mineral

SmartMat
Functional chiral suprastructures are common in biology, including in biomineralization, and they are frequently found in many hardened structures of both marine and terrestrial invertebrates, and even in pathologic human otoconia of the inner ear ...

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

Advanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

Characteristics of guided modes in graphene-coated chiral nihility fibers.

PLoS ONE
In this paper, guided modes in isotropic chiral nihility metamaterial fibers coated with graphene layers supported by conventional dielectric material are studied theoretically. Kubo formalism is applied to model the conductivity of single-layer graphene,

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids

Advanced Materials, EarlyView.
Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...
