FTIR studies

The authors suggested that correction of the Amide I and II peaks could be carried out by visually fitting a scaled buffer spectrum to the raw cell spectrum, until the resulting corrected spectrum shows a normal Amide A envelope. Although subjective, Miljkovic et al. demonstrated that it was possible to 

A recent study by Draux et al. investigated different optical substrates, quartz, calcium fluoride and zinc selenide, for preservation of cell integrity for Raman spectroscopy of single living cells. Quartz was found to be the most appropriate based on cell morphology and proliferation rate.

The experimental data and arguments by Trassatti [25] show that at the PZC, the water dipole contribution to the potential drop across the interface is relatively small, varying from about 0 V for An to about 0.2 V for In and Cd. For transition metals, values as high as 0.4 V are suggested. The basic idea of water clusters on the electrode surface dissociating as the electric field is increased has also been supported by in situ Fourier transfomr infrared (FTIR) studies [26], and this model also underlies more recent statistical mechanical studies [27].

The major contributions of the Co sites in CoSx-MoSx/NaY to the HYD and HDS reactions were corroborated by a FTIR study of NO adsorption. Figure 7 shows the IR spectra of NO adsorbed on CoSx/NaY (2.1Co/SC) and CoSx-MoSx/NaY (2.1Co 2.1Mo/SC). Nitric oxide... 

The FTIR studies revealed that the formation of CO2 is only detected when the CO starts to be oxidized (Fig. 6.18). Therefore, it was proposed that the mechanism has only one path, with CO as the C02-forming intermediate [Chang et al., 1992 Vielstich and Xia, 1995]. This has two important and practical consequences. First, methanol oxidation will be catalyzed by the same adatoms that catalyze CO oxidation, mainly ruthenium. Second, since the steric requirements for CO formation from methanol are quite high, the catalytic activity of small (<4nm) nanoparticles diminishes [Park et al., 2002].
