We report on transient 2D Fourier transform infrared spectroscopy (2DIR) after vibrational ladder climbing induced in the CO-moiety longitudinal stretch of carboxyhemoglobin. The population distribution, spreading up to seven vibrational levels, results in a nonequilibrium 2DIR spectrum evidencing a large...
Infrared nanospectroscopy of single Aβ42 oligomers and fibrils We first applied conventional bulk IR spectroscopy to investigate the chemical binding between Aβ42 fibrils formed at the end of the aggregation reaction (plateau phase, 4 h) and bexarotene (Supplementary Fig.4). However, with bulk...
Mid-infrared spectroscopy is a sensitive and selective technique for probing molecules in the gas or liquid phase. Investigating chemical reactions in bio-medical applications such as drug production is recently gaining particular interest. However, monitoring dynamic processes in liquids is commonly limite...
Infrared spectroscopy coupled with multivariate analyses such as linear regressions was applied to assess the main cell wall components of a huge diversity of fruits and vegetables belonging to 29 plant species. The methodology was tested on the raw freeze-dried powders and on their corresponding AIS...
The fraction of each fluorescent component of the overall fluorescence was significantly affected by type of land-use, climatic region and the interaction between them (Table 5). Moreover, the lowest p-values (i.e., highest significance level) were obtained for these fractions. This observation ...
(DBI)33use the Thermal Infrared (TIR) band from the Landsat OLI instrument to improve the discrimination of built-up areas and bare soil in dry climates. Likewise, Soil Indices like the Bareness Index (BaI)34were created for detecting the degree of bareness on the surface using bands from ...
