Abstract:
Molybdenum oxide thin films are deposited by thermal evaporation and sputtering, and lithium is inserted by a dry lithiation method. The FT-IR/ATR technique is used to study the formation and evolution of lithium bronze and lithium molybdate species. The mechanism of lithium intercalation is found to be dependent on the method of film preparation. The involvement of water molecules in the kinetics of lithiation is stressed.

Abstract:
Deposition of the vanadium pentoxide on a KRS-5 ATR crystal by dip-coating has led to the formation of a thallium bronze. ATR spectroscopy is used to study the changes in the spectral pattern induced by the heat treatment of the films. The results show that both the spectrum of the xerogel and its evolution depend on the precursors and the method of preparation. The spectra of the heated thin films suggest an irreversible structural change taking place at a temperature around 220°C.

In particular, the sample alloys were investigated by different chemical and morphological analysis.

Subsequently, a surface analysis was realized by molecular spectroscopy to identify the alteration patinas on surfaces (such as bronze disease).

Abstract:
Recently FT-IR analysis has been employed to study changes in molecular signatures during embryonic stem cell differentiation. We were interested to find out whether FT-IR spectroscopy could be applied to analyze changes in human skin mesenchymal stem cell (S-MSC) biochemical profile duringin vitroneurodifferentiation. S-MSCs were propagated in serum-free medium with EGF and FGF-2 during six weeks. Neural progenitor cell line ReNcell CX (Millipore) was used as a reference cell line. Samples were collected each week and analyzed for neural marker nestin, tubulinβIII, GFAP, and CD271 expression.

Abstract:
Time-resolved Fourier transform infrared spectroscopy (FT-IR) offers distinct advantages concerning restrictions pertinent to biomolecules. In particular, it is possible to monitor the temporal evolution of the reaction mechanism of complex machineries as membrane proteins, where other techniques encounter significant experimental difficulties. Here, we present the classical principles and experimental realizations of time-resolved FT-IR spectroscopy together with recent developments employed in our laboratory. Examples from applications to retinal proteins are reviewed that underline the impa

Abstract:
Fourier transform photoacoustic spectroscopy (FT-IR/PAS) has proven to be a powerful technique for the near-surface characterization of solid materials. The effective sampling depth of FT-IR/PAS can be varied by using different interferometer mirror velocities, so that nondestructive depth profiling can be performed. In this research, sized cotton yarns, treated glass fibers, chemically modified poly(ethylene terephthalate) fibers, and a naturally weathered poly(vinyl chloride) composite were investigated with the use of FT-IR/PAS at different mirror velocities.

Abstract:
The technique of infrared emission spectroscopy (IRES) is reviewed and further examined in this study as a surface analysis tool. A system has been designed which allows simultaneous kinetic and in situ infrared emission analysis of catalyst surfaces. IRES spectra of several gas mixture/solid systems are obtained in order to examine sample preparation and spectra processing issues; these systems include Pt/Al2O3 exposed to CO and CO-NO mixtures, an oxidized copper plate, and a zeolite exposed to inert atmospheres. For the temperature range of importance to catalysis (300–600 K), IRES is limite

Abstract:
The practical aspects of infrared emission spectroscopy are reviewed briefly, with emphasis on recent developments and on special problems encountered in measurements of adsorbed species on opaque substrates. A few examples are given for cases when the species of interest give rise to inverted emission bands on the background of substrate emission. The feasibility of recording IR emission spectra of adsorbates on metal powders is demonstrated.
