We have investigated the individual magnetic moments of Ni, Mn and Tb atoms in the intermetallic compound TbNi2Mn in the Laves phase (magnetic phase transition temperature TC ∼131 K) by X-ray magnetic circular dichroism (XMCD) studies at 300 K, 80 K and 20 K. Analyses of the experimental results reveal that Ni atoms at 20 K in an applied magnetic field of 1 T carry an intrinsic magnetic moment ...

A user-friendly website for the analysis of protein secondary structures from Circular Dichroism (CD) and Synchrotron Radiation Circular Dichroism (SRCD) spectra has been created.

The linearly polarized x-ray-absorption dichroism at the Dy 3d-4f edge is studied for three dilerent kinds of interfaces: Dy on disordered Si(111),Dy on amorphous Si02, and Dy on polycrystalline Ta. Strong dichroism is observed in all the three interfaces, despite the very different interactions of Dy with the substrates. It is therefore pointed out that the x-ray-absorption dichroism using lin...

Circular dichroism and helical are intriguing chiroptical phenomena with broad applications in optical sensing imaging. Here, we generalize one of the phenomena-helical dichroism-to acoustics. We show that a one-dimensional lattice chiral resonators loss can induce differential absorption sounds (i.e., acoustic vortices) carrying opposite orbital angular momentum (OAM). This strongly depends on...

In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...

Background: Recently, botulinum neurotoxin (BoNT)-derived recombinant proteins have been suggested as potential botulism vaccines. Here, with concentrating on BoNT type E (BoNT/E), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of BoNT serotypes A, B and E binding subdomains, and a monovalent recombinant protein, which contains...

Poly(2,7-di-n-pentyldibenzofulvene)s with no stereocenters, obtained by anionic polymerization using chiral 9-fluorenyllithium ligand complexes, showed intense circular dichroism in film form due purely to the chiral conformation of the main chain, while no chiroptical properties were detectable in solution.
