Self-Assembly of N-Rich Triimidazoles on Ag(111): Mixing the Pleasures and Pains of Epitaxy and Strain
Christian Wäckerlin, Ulrich Aschauer, Xing Wang, Mehdi Heydari
In the present report, homochiral hydrogen-bonded assemblies of heavily N-doped (C9H6N6) heterocyclic triimidazole (TT) molecules on an Ag(111) substrate were investigated using scanning tunneling microscopy (STM) and low energy electron diffraction (LEED) ...
Washington2023Updates on moleculARweb, the Swiss Portal for Chemistry and Structural Biology Education Using Augmented and now also Virtual Reality
Luciano Andres Abriata, Fabio Jose Cortes Rodriguez
We present a new activity on the moleculARweb plat-form on molecular symmetry elements, two more languages, a new marker-less augmented reality mode, and a new virtual reality tool for VR headsets. ...
SWISS CHEMICAL SOC2023Emergence of Nontrivial Low-Energy Dirac Fermions in Antiferromagnetic EuCd2As2
Vladimir N. Strocov, Joël Mesot, Pierre Richard, Han Wang, Hang Li
Parity-time symmetry plays an essential role for the formation of Dirac states in Dirac semimetals. So far, all of the experimentally identified topologically nontrivial Dirac semimetals (DSMs) possess both parity and time reversal symmetry. The realizatio ...
WILEY-V C H VERLAG GMBH2020Time-reversal symmetry for systems in a constant external magnetic field
Sara Bonella, Alessandro Coretti
The time-reversal properties of charged systems in a constant external magnetic field are reconsidered in this paper. We show that the evolution equations of the system are invariant under a new symmetry operation that implies a new signature property for ...
Amer Physical Soc2017Torque magnetometry study of magnetically ordered state and spin reorientation in the quasi-one-dimensional S=1/2 Heisenberg antiferromagnet CuSb2O6
The antiferromagnetically ordered state of the monoclinic quasi-one-dimensional S = 1/2 Heisenberg antiferromagnet CuSb2O6 was studied combining torque magnetometry with a phenomenological approach to magnetic anisotropy. This system is known to have a num ...
Amer Physical Soc2015Cryogenic Spectroscopy and Quantum Molecular Dynamics Determine the Structure of Cyclic Intermediates Involved in Peptide Sequence Scrambling
Ursula Röthlisberger, Thomas Rizzo, Marta Andreia Da Silva Perez, Oleg Aseev
Collision-induced dissociation (CID) is a key technique used in mass spectrometry-based peptide sequencing. Collisionally activated peptides undergo statistical dissociation, forming a series of backbone fragment ions that reflect their amino acid (AA) seq ...
2015In Search of Ferroelectricity in Antiferroelectric Lead Zirconate
Since the prediction of antiferroelectricity and the subsequent discovery of PbZrO3, the description of antiferroelectric behaviour in materials has been constantly modified to account for the latest properties identified in antiferroelectric materials. Ad ...
EPFL2015Bloch Theorem With Revised Boundary Conditions Applied To Glide Plane And Screw Axis Symmetric, Quasi-One-Dimensional Structures
Alessandro Spadoni, Florian Paul Robert Maurin
Bloch theorem provides a useful tool to analyze wave propagation in periodic systems. It has been widely used in physics to obtain the energy bands of various translationally-periodic cristals and with the advent of nanosciences like nanotubes, it has been ...
Int Center Numerical Methods Engineering2014Critical current anisotropy in Nd-1111 single crystals and the influence of neutron irradiation
Janusz Andrzej Karpinski, Sergiy Katrych
We report on angle-resolved magnetization measurements on NdFeAsO0.65F0.35 ( Nd-1111) single crystals. The field dependence of the critical current density, Jc, is non-monotonic in these crystals at all orientations and temperatures due to the fishtail eff ...
Iop Publishing Ltd2014Evolution of magnetic and crystal structures in the multiferroic FeTe2O5Br
Neutron diffraction and nuclear quadrupole resonance (NQR) measurements were employed to investigate magnetic order in the nonferroelectric phase preceding the low-temperature multiferroic state in FeTe2O5Br. Refinement of the neutron diffraction data and ...
