WebThe fine-tuning of chiral microenvironments within the well-defined complexes has enabled outstanding chiral discrimination properties, leading to highly enantio- and helix-sense-selective recognition for chiral amino alcohols (up to 9.35). ... Specifically, the molecular helicity of the complexes can be controlled by the absolute ... WebApr 30, 1999 · These structures, in turn, self-assemble to form coiled-coil aggregates with left-handed helicity. Addition of potassium ions to the fibers leaves their structure intact but blocks the transfer of the chirality from the tails to the cores, leading to loss of the helicity of the fibers. These tunable chiral materials have potential in ...

WebJun 2, 2024 · Being able to sense and distinguish the handedness of chiral molecules is crucial for many applications in the life sciences. Here, we explore by theoretical and computational means the ability of achiral and helicity preserving photonic nanostructures to enhance the optical rotation, i.e., the polarization rotation of elliptically polarized light … Web22 hours ago · The onset of helicity decay is determined by the time when the chiral magnetic effect becomes efficient at the peak of the initial magnetic energy spectrum. When spin flipping is important, the chiral chemical potential vanishes and the magnetic helicity becomes constant, which leads to a faster increase of the correlation length, as expected ...
