AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...
The three-dimensional (3D) structures of proteins and peptides in vivo largely determine their biological functions. In vitro these native structures and their heterogeneity reflect a subtle balance between noncovalent intramolecular interactions and those ...
We apply gas-phase double resonance spectroscopic techniques to two helical peptides, Ac-Phe-(Ala)5-Lys-H+ and Ac-Phe- (Ala)10-Lys-H+, using electrospray ionization combined with photofragmentation in a cold, 22-pole ion trap. Despite the large size of the ...
This thesis aimed at developing new, simple methods of calibration for on-line monitoring of bioprocesses by Fourier-transform mid-infrared spectroscopy (FTIR). The conventional calibration approach implies the preparation and measurement of a large number ...
Results of the single molecule force spectroscopy study of specific interactions between ribonuclease barnase and its inhibitor barstar are presented. Experimental data obtained for the force loading rate ranging 2-70 nN/s are well approximated by a single ...
This work aims to develop arrays of individually actuated cell force spectroscopy probes. Cross et al. (Nat. Nanotech. 2007) have shown that human cells undergo substantial mechanical changes as they become cancerous. Cell force spectroscopy using AFM has ...
Sacrificial bonds and hidden length in structural molecules and composites have been found to greatly increase the fracture toughness of biomaterials by providing a reversible, molecular-scale energy-dissipation mechanism. This mechanism relies on the ener ...
Atomic force microscopy has become potent tool for investigating interand intramolecular interactions. Single molecule force spectroscopy on supramolecular guest-host-complexes reveal information about the depth of the binding pocket and thermal off-rates. ...
This thesis reports on results of three different experiments of photo-induced structural dynamics in the condensed phase, investigated by time-resolved pump-probe spectroscopy with femtosecond time-resolution. In the first part, we address the ultrafast d ...
The environment is important for the exact course of a chemical reaction. As an example of the strong influence of the environment on the reaction, this work studies the isomerization reaction of the chromophore retinal in the binding pocket of the protein ...
