The excitation of plasmon-polariton modes on the surface of metallic nanoparticles (NPs) enables a variety of applications for these materials, such as photocatalysts and photovoltaic and sensing devices. Plasmon excitation in NPs implies an increase in the intensity of spectroscopic signals from adsorbed molecules, in particular, the enhancement of Raman spectra (surface-enhanced Raman s…

Several research activities in the Laboratório de Espectroscopia Molecular, Instituto de Química, Universidade de São Paulo, LEM/IQ-USP, are related to infrared and Raman spectroscopy. Coupling of optical microscopes to infrared and Raman spectrometers provides to vibrational spectroscopy the spatial resolution of the order of micrometer or below micrometer, then combining molecular struc…

Several research activities in the Laboratório de Espectroscopia Molecular, Instituto de Química, Universidade de São Paulo, LEM/IQ-USP, are related with infrared and Raman spectroscopy of condensed phases, such as interfaces, colloids, electrodes, molecular and ionic liquids, molecular probes in non-aqueous solvents, polymers, carbon nanotubes etc. In this research project, spectroscopic…
Room temperature molten salts, the so-called ionic liquids, have been an issue of great interest in the last years proper to many different applications, e.g. alternative solvents for synthesis and electrolytes for electrochemical devices. Several ionic liquids are viscous liquids, which are easily supercooled with typical glass transition temperature Tg ~ 190 K. In this work, low-frequen…

The various applications proposed over the last two decades for ionic liquids (LIs) and deep euthetic solvents (DES) demand their characterization with thermal, reological and ionic conductivity measurements in function of temperature. Spectroscopic techniques are employed, in particular vibrational spectroscopy (Raman and infrared), for the rationalization of macroscopic properties in te…
A number of ionic materials have been integrated for use in energy generation and storage systems. Ionic liquids and organic ionic plastic crystals stand out among these materials because they are made entirely of ions and have physical-chemical properties that make them suited for use as electrolytes in electrochemical systems. The Molecular Spectroscopy Laboratory of the Chemistry Insti…

By the end of 1990´s and beginning of 2000´s, there was a sharp increase in the scientific literature about Ionic Liquids (IL). From the 2010´s, another kynd of alternative solvents, although closely related to ILs, starts drawing attention to the scientific community: the Deep Eutectic Solvents (DES). The DES are prepared from many different solid salts at room temperature that lead to a…
Salts with low melting points, the so-called ionic liquids, exhibit complex phase diagrams since glass transition or crystallization are seen depending on the rate of change of temperature and pressure. In the past years we have been studying thermodynamics, structure and dynamics of ionic liquids in the Laboratório de Espectroscopia Molecular do Instituto de Química da USP, LEM/IQ-USP. W…
Many low temperature molten salts, the so-called ionic liquids, are viscous liquids with complex phase diagrams, as glass transition or crystallization takes place depending on the rate of change of temperature and pressure. In the Laboratório de Espectroscopia Molecular, LEM/IQ-USP, we have been studying Thermodynamics, structure, and dynamics of ionic liquids by calorimetry, X-ray and R…

One of the most fundamental properties of the ionic liquids (ILs) is the melting point.Although several relations can be made between the chemical structure of the ions and the melting point, their accurate prediction and explanation for ILs is far from trivial. Computer simulations are valuable tools in order to give molecular level insights over several physical properties of the ILs, h…
The investigation of the collective dynamics in disordered systems is a very active research field since the beginning of modern science. Some ionic liquids are good glass formers and excellent model systems for studying complex dynamics. We have investigated the phase behavior and structure of these ionic liquids by differential scanning calorimetry, Raman spectroscopy, and X-ray diffrac…
The project to which this BEPE proposal is related, entitled "Collective dynamics of ionic liquids", FAPESP process 2015/07516-8 has as part of its objectives the determination of the acoustic dispersion curves, i.e., determination of the excitation energy of the acoustic modes as a function of their wavevector (or momentum transfer) for different ionic liquids and their Li+ solutions.
