8 p, 1.3 MB Evidence of exciton-libron coupling in chirally adsorbed single molecules / Doležal, Jiří (Charles University. Faculty of Mathematics and Physics) ; Canola, Sofia (Czech Academy of Sciences. Institute of Physics) ; Hapala, Prokop (Czech Academy of Sciences. Institute of Physics) ; de Campos Ferreira, Rodrigo Cezar (Czech Academy of Sciences. Institute of Physics) ; Merino, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Švec, Martin (Czech Academy of Sciences. Institute of Organic Chemistry and Biochemistry)
Interplay between motion of nuclei and excitations has an important role in molecular photophysics of natural and artificial structures. Here we provide a detailed analysis of coupling between quantized librational modes (librons) and charged excited states (trions) on single phthalocyanine dyes adsorbed on a surface. [...]

Departament de Física) ; Sort Viñas, Jordi (Universitat Autònoma de Barcelona. Departament de Física)
The magnetic properties of mesoporous cobalt ferrite films can be largely tuned by the application of an electric field using a liquid dielectric electrolyte. By applying a negative voltage, the cobalt ferrite becomes reduced, leading to an increase in saturation magnetization of 15% (M) and reduction in coercivity (H) between 5-28%, depending on the voltage applied (−10 V to −50 V). [...]

Transthyretin (TTR) is a tetrameric beta-sheet-rich protein. Its deposits have been implicated in four different amyloid diseases. Although aggregation of the wild-type sequence is responsible for the senile form of the disease, more than one hundred variants have been described thus far, most of which confer a more amyloidogenic character to TTR, mainly because they compromise the stability of the protein in relation to monomer formation, which upon misfolding is intrinsically aggregation-prone.
