Buckling of chiral elastic rings spanned by fluid films

open access: yesVietnam Journal of Mechanics, 2022
We use variational method to examine buckling of chiral elastic rings spanned by fluid films. We find that the critical surface tension of the fluid film at which buckling occurs depends on the degree of chirality, regardless whether the ring possesses ...

Cell Chirality Drives Left-Right Asymmetric Morphogenesis

open access: yesFrontiers in Cell and Developmental Biology, 2018
Most macromolecules found in cells are chiral, meaning that they cannot be superimposed onto their mirror image. However, cells themselves can also be chiral, a subject that has received little attention until very recently.

Evolution of helicity in NOAA 10923 over three consecutive solar rotations

open access: yes, 2008
We have studied the evolution of magnetic helicity and chirality in an active region over three consecutive solar rotations. The region when it first appeared was named NOAA10923 and in subsequent rotations it was numbered NOAA 10930, 10935 and 10941. We

Chiral sensors

open access: yesTrAC Trends in Analytical Chemistry, 2019
Chirality has a crucial effect on clinical, chemical and biological research since most bioactive substances possess chirality in the natural world. Thus, new effective methods and/or (nano)materials are required to explain chiral recognition of chiral substances, which always become a hot topic in pharmaceutical and chemo/biological study.

Microstructure Effects for Casimir Forces in Chiral Metamaterials

open access: yes, 2010
We examine a recent prediction for the chirality-dependence of the Casimir force in chiral metamaterials by numerical computation of the forces between the exact microstructures, rather than homogeneous approximations.

Alternative Kullback-Leibler information entropy for enantiomers [PDF]

open access: yes, 2010
In our series of studies on quantifying chirality, a new chirality measure is proposed in this work based on the Kullback-Leibler information entropy.

Chiral Nanoceramics

open access: yesAdvanced Materials, 2020
AbstractThe study of different chiral inorganic nanomaterials has been experiencing rapid growth during the past decade, with its primary focus on metals and semiconductors. Ceramic materials can substantially expand the range of mechanical, optical, chemical, electrical, magnetic, and biological properties of chiral nanostructures, further stimulating

Chiral supergravity [PDF]

open access: yesJournal of High Energy Physics, 2009
We study the linearized approximation of N=1 topologically massive supergravity around AdS3. Linearized gravitino fields are explicitly constructed. For appropriate boundary conditions, the conserved charges demonstrate chiral behavior, so that chiral gravity can be consistently extended to chiral supergravity.

Spiral Galaxies as Enantiomers: Chirality, an Underlying Feature in Chemistry and Astrophysics

open access: yes, 2005
Spiral galaxies are axi-symmetric objects showing 2D-chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in aminoacids ...
