Spectroscopic studies of SnO2 doped with Cr, Co or Nb
(2003-03-15)
SnO2 ceramics doped with different amounts of Co, Cr or Nb were investigated using visible and infrared spectroscopy at room temperature. Based on the observed d-d transitions the valence states of incorporated dopants ...

External cavity-quantum cascade laser infrared spectroscopy for secondary structure analysis of proteins at low concentrations
(Nature Publishing Group, 2016-09)
Fourier transform infrared (FTIR) and circular dichroism (CD) spectroscopy are analytical techniques employed for the analysis of protein secondary structure. The use of CD spectroscopy is limited to low protein concentrations ...

Synthesis and spectroscopic characterization of a novel coordination polymer of palladium(II) with pyrazole and azido ligands
(2002-12-01)
The one-dimensional coordination polymer of palladium(II) with pyrazolato (Pz -) and azide (N 3 -) as bridging ligands, of formula [Pd 3(μ-N 3)(μ-Pz) 5] n, has been prepared. From IR and Raman studies it was evidenced the ...

The use of FT-IR spectroscopy and SEM/EDS characterization of slips and pigments to determine the provenances of archaeological ceramics: The case of Guanacaste ceramics (Costa Rica)
(2021-03)
In this paper, the red and black pigments and slips of 63 Guanacaste ceramics were analyzed by Scanning Electronic Microscopy and infrared spectroscopy. All the pigment layers were made by dilution of a pure pigment in the ...
Recent advancements of EC-QCL based mid-IR transmission spectroscopy of proteins and application to analysis of bovine milk
(IOS Press, 2018-01)
Background:High emission powers of external cavity-quantum cascade laser (EC-QCL) light sources allow to employ significantly larger path lengths for infrared (IR) transmission measurements compared to conventional ...
