Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
To study the electronic interactions in donor-acceptor (D-A) ensembles, D and A fragments are coupled in a single molecule. Specifically, a tetrathiafulvalene (TTF)-fused dipyrido[3,2-a:2′,3′-c]phenazine (dppz) compound having inherent redox centers has be ...
The aim of this thesis is to optimise and gain fundamental information on two applications of photomedicine using fluorescence imaging and spectrofluorometry: (1) the detection of early bronchial cancer by autofluorescence imaging and (2) the endometrial a ...
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 ...
The dye coumarin 343 (C343) adsorbed on the surface of ZrO2 nanoparticles in aq. solns. was used to study the solvation dynamics close to these surfaces. The time-resolved Stokes shift was measured by femtosecond frequency-resolved upconversion. The absorp ...
Photo-induced excited-state reactions stand in the center of function of the photosensitive biological systems. These reactions can be accompanied by structural changes of the chromophore (for example isomerization) which are influenced by the nearest envi ...
The excitation of the Rydberg states is used to study the nonpolar solvation dynamics in supercrit. fluids (SCFs). The system NO in supercrit. Ar serves as the model system. First, the steady-state, absorption and fluorescence spectra of the NO X 2P-A 2S+( ...
Time-integrated fluorescence expts. on native bacteriorhodopsin and on its non-isomerizing form bR5.12 are reported. The exptl. set-up was designed such as to observe emission exclusively from the excited state intermediate I-460. We obtain the first syste ...
We have employed femtosecond laser writing in order to induce refractive- index changes and waveguides in Ti3+-doped sapphire. Doping the sapphire crystal with an appropriate ion significantly reduces the threshold for creating structural changes, thus e ...
The ultrafast spectral evolution of the fluorescence of the all-trans protonated Schiff base of retinal (PSBR) in alcs. with different polarity was studied using the fluorescence up-conversion technique in a "polychromatic mode". Results reveal that vibr ...
