Abstract Nano-Fourier-transform infrared spectroscopy (nano-FTIR) combines with scanning probe microscopy (SPM) techniques and enables spectroscopic imaging of molecular electronic properties matter at nanometer spatial resolution. The can be used to derive chemical mappings, i.e. the distribution concentrations species contained in a given sample. However, due sequential principle underlying S...

PROBLEM Historically, hydrogen has been employed in a variety of industrial chemical processes. Typically, the purity requirements for this hydrogen have tolerated contaminant levels ranging from ppm to low percentages, depending upon the application. The use of hydrogen has now expanded into novel applications such as alternative fuel for use in transportation and stationary electrical generat...

Micro-scale analytical techniques permit correlation of chemistry with morphology of individual Proterozoic acritarchs (organic-walled microfossils), and thus provide new approaches for elucidating their biological affinities. A combination of micro-Fourier transform infrared (FTIR) spectroscopy and laser micro-Raman spectroscopy was used to investigate the organic structure and composition of ...

The ASTM Acid Number (AN) and Base Number (BN) analyses provide two of the most fundamental condition monitoring measures associated with lubricant quality, providing status information on oil oxidation and/or reserve alkalinity, respectively. Although a crucial measure, the various ASTM titrimetric methods are expensive and problematic to carry out as well as being difficult to compare and int...
