Direct Observation of Desorption of a Melt of Long Polymer Chains
(Nature, 2020-08-28)Tuning the thermodynamic state of a material has a tremendous impact on its performance. In the case of polymers placed in proximity of a solid wall, this is possible by annealing above the glass transition temperature, ... -
Divalent EuRh2Si2 as a Reference for the Luttinger Theorem and Antiferromagnetism in Trivalent Heavy-Fermion YbRh2Si2
(Nature Publishing Group, 2019-02-15)Application of the Luttinger theorem to the Kondo lattice YbRh2Si2 suggests that its large 4f derived Fermi surface (FS) in the paramagnetic (PM) regime should be similar in shape and volume to that of the divalent ... -
Domain wall dynamics of magnetically bistable microwires
(EDP Sciences, 2012-06)We studied domain wall propagation of magnetically-bistable Fe-Co-rich microwires paying attention on effect of applied and internal stresses. We measured hysteresis loops and domain wall propagation in various magnetic ... -
Domain walls collision in Fe-rich and Co-rich glass covered microwires
(EDP Sciences, 2013-01)We report the results of the investigation of domain walls propagation in Fe-rich and Co-rich microwires performed using Sixtus-Tonks and magneto-optical Kerr effect techniques. It was found that under certain experimental ... -
Dynamics of aqueous peptide solutions in folded and disordered states examined by dynamic light scattering and dielectric spectroscopy
(Royal Society of Chemistry, 2021-06-24)[EN] Characterizing the segmental dynamics of proteins, and intrinsically disordered proteins in particular, is a challenge in biophysics. In this study, by combining data from broadband dielectric spectroscopy (BDS) and ... -
