Circular dichroism of chiral Majorana states

Beilstein Journal of Nanotechnology, 2018
Background: Majorana states in condensed matter devices may be of a localized nature, such as in hybrid semiconductor/superconductor nanowires, or chirally propagating along the edges such as in hybrid 2D quantum-anomalous Hall/superconductor structures ...

Protein fiber linear dichroism for structure determination and kinetics in a low-volume, low-wavelength couette flow cell [PDF]

, 2004
High-resolution structure determination of soluble globular proteins relies heavily on x-ray crystallography techniques. Such an approach is often ineffective for investigations into the structure of fibrous proteins as these proteins generally do not ...

Eradicating Backscattering through Circular Conversion Dichroism in Optical Regime

, 2023
Circular dichroism (CD) and asymmetric transmission (AT) are two outstanding chiroptical effects, which can be produced by planar chiral devices due to their distinct response to oppositely handed input light.

Calibration and standardisation of synchrotron radiation circular dichroism and conventional circular dichroism spectrophotometers [PDF]

, 2003
Synchrotron radiation circular dichroism (SRCD) is an emerging technique in structural biology with particular value in protein secondary structure analyses since it permits the collection of data down to much lower wavelengths than conventional ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Circular Dichroism in Study of Drug Chirality

Антибиотики и Химиотерапия, 2020
Verapamyl substance and market verapamyl were investigated with circular dichroism. It was shown that circular dichroism provided rapid and highly efficient determination of the optic isomers and could be recommended as a method for control of drug ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Gate-tunable circular phonon dichroism effect in bilayer graphene

iScience
Summary: Circular phonon dichroism effect has been proposed in two-dimensional materials; however, the lack of tunability hinders the exploration of the effect.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Folding factors and partners for the intrinsically disordered protein Micro-Exon Gene 14 (MEG-14) [PDF]

, 2013
The micro-exon genes (MEG) of Schistosoma mansoni, a parasite responsible for the second most widely spread tropical disease, code for small secreted proteins with sequences unique to the Schistosoma genera.
