Hard X-ray helical dichroism of disordered molecular media

Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Malte Oppermann, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Christian David, Jérôme Lacour

Chirality is a structural property of molecules lacking mirror symmetry that has strong implications in diverse fields, ranging from life sciences to materials science. Chirality-sensitive spectroscopic methods, such as circular dichroism, exhibit weak sig ...

Promising anti-cancer potency of 4,5,6,7-tetrahydrobenzo[d]thiazole-based Schiff-bases

Kurt Schenk, Farzaneh Fadaei Tirani

Four new Schiff-bases have been synthesized from the 1:2 M condensation of 4,5,6,7-tetrahydrobenzothiazole-2,6-diamine with 2-hydroxybenzaldehyde (SL3), 5-Bromo-2-hydroxybenzaldehyde (SL2), 2-hydroxy-3-methoxybenzaldehyde (SL3) and 2-hydroxy-1-naphthaldehy ...

X-ray absorption linear dichroism at the Ti K-edge of rutile (001) TiO2 single crystal

Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Thomas Charles Henry Rossi, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Jérémy Raymond Jean Maurice Rouxel

X-ray absorption linear dichroism of rutile TiO2 at the Ti K-edge provides information about the electronic states involved in the pre-edge transitions. Here, linear dichroism with high energy resolution is analyzed in combination with ab initio finite dif ...

Terahertz-optical properties of a bismuth ferrite single crystal

Henrik Moodysson Rønnow, Jean-Philippe Ansermet, Marcin Bialek

Transmission through a (100)-oriented single crystal of bismuth ferrite (BiFeO3) was studied at frequencies of 0.485-0.765 THz with a continuous-wave source and in the temperature range of 30-350 K as a function of polarization angle. The fine splitting of ...

Broad-Band Ultraviolet CD Spectroscopy of Ultrafast Peptide Backbone Conformational Dynamics

Majed Chergui, Malte Oppermann, Benjamin Bauer

The far-UV spectral window widely used for the conformational analysis of biomolecules is not easily covered with broad-band lasers. This has made it difficult to use circular dichroism (CD) spectroscopy to directly follow fast structure changes. By combin ...

Accessible Superchiral Near-Fields Driven by Tailored Electric and Magnetic Resonances in All-Dielectric Nanostructures

Hatice Altug, Andreas Tittl, Yasaman Jahani, Kosmas Tsakmakidis, Ershad Mohammadi

Detection and differentiation of enantiomers in small quantities are crucially important in many scientific fields, including biology, chemistry, and pharmacy. Chiral molecules manifest their handedness in their interaction with the chiral state of light ( ...

X-ray absorption linear dichroism at the Ti K edge of anatase TiO2 single crystals

Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Thomas Charles Henry Rossi, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Jérémy Raymond Jean Maurice Rouxel

Anatase TiO2 (a-TiO2) exhibits a strong x-ray absorption linear dichroism in the pre-edge, the XANES and the EXAFS at the titanium K edge. In the pre-edge region, the behavior of the A1-A3 and B peaks originating from the 1s - 3d transitions is due to the ...

Hydro-mechanical behaviour of shallow Opalinus Clay shale

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

In Switzerland, Opalinus Clay shale has been selected as the host formation for radioactive waste disposal. The minimum required depth of the repository is related to the long-lasting isolation required for the disposal (1 million years). During this perio ...
