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.
The dynamics and bonding of the complex hydride LiBH4 have been investigated by vibrational spectroscopy and density functional theory (DFT). The combination of infrared, Raman, and inelastic neutron-scattering (INS) spectroscopies on hydrided and deuterat ...
There has been a very strong development of the sensors based on surface plasmon resonance during the last thirty years, mostly for biological and biomedical applications. If the first experiments in this field were carried out at the beginning of the 20t ...
Silicon-based digital camera sensors exhibit significant sensitivity beyond the visible spectrum (400-700nm). They are able to capture wavelengths up to 1100 nm, i.e., they are sensitive to near-infrared (NIR) radiation. This additional information is conv ...
Metamaterial-based perfect absorbers utilize intrinsic loss, with the aid of appropriate structural design, to achieve near unity absorption at a certain wavelength. For most of the reported absorbers, the absorption occurs only at a single wavelength wher ...
The different parts of the electromagnetic spectrum result in diverse effects upon interaction with matter: according to the wavelength, the radiation has energy appropriate for the excitation of a specific physical process. X-rays can be used as a tool to ...
Infrared absorption spectroscopy enabling direct access to vibrational fingerprints of the molecular structure is a powerful method for functional studies of bio-molecules. Although the intrinsic absorption cross-sections of IR active modes of proteins are ...
The IR reflectance spectra of the cubic noncentrosymmetric ferrimagnet Cu2OSeO3 (T-C approximate to 60 K) were investigated in the temperature range 10-80 K. Detailed analysis of the symmetry and composition of vibrational modes was conducted on the basis ...
Strong Electric-field enhancement in small volumes is the key for label-free single-molecule sensing. We have investigated the excitation of single and multiple metallic nano-cavities by evanescent wave coupling in the near-infrared by a silicon wire waveg ...
In this thesis, I describe the design and first applications of a new molecular-beam/surface-science ultra-high vacuum apparatus. The new machine combines rovibrational state-selective infrared pumping of gas-phase reactants with reflection absorption infr ...
