Spectral reconstruction for shifted-excitation Raman difference spectroscopy (SERDS)

Fluorescence emission has been one of the major obstacles to apply Raman spectroscopy in biological investigations. It is usually several orders more intense than Raman scattering and hampers further analysis....

Raman spectroscopic investigation of the human liver stem cell line HepaRG

In this work, Raman spectroscopic cell imaging approaches and a discrimination between HepG2, non-differentiated HepaRG, and differentiated hepatocyte-like HepaRG cells are presented. Raman spectroscopic...

Model transfer for Raman spectroscopy based bacterial classification

Raman spectroscopy is gaining increasing attention in biomedical diagnostics thanks to instrumental development and chemometric approaches enhancing the accuracy and speed of this technique. Meanwhile,...

The use of ostrich eggs for in ovo research – Making preclinical imaging research affordable and available

In ovo research is a valuable option of preclinical research, but imaging studies are severely limited by the costs of dedicated equipment needed for small-size eggs. We sought to verify the feasibility...

Monitoring of gas composition in a laboratory biogas plant using cavity enhanced Raman spectroscopy

Biogas production from organic raw materials is a highly complex biotechnological process. The responsible anaerobic fermentation process is difficult to measure due to its multi-stage nature. Still, optimization...

Low-frequency vibrational modes, non-Debye normalization and structural heterogeneity in binary SiO2-Al2O3 glasses

In binary aluminosilicate liquids and glasses, heterogeneity on intermediate length scale is a crucial factor for optical fiber performance, determining the lower limit of optical attenuation and Rayleigh...

Microbial Fe(II) oxidation by Sideroxydans lithotrophicus strain ES-1 in the presence of humic acids

Controlled laboratory experiments were combined with field measurements to better understand the interactions between dissolved organic carbon and reduced iron in organic rich peatlands. Addition of peat-derived...

High performance graphene coating for the applications in photovoltaics, optics, electronics and corrosion protection

Electroarchitected porous platinum on metallic multijunction nanolayers to optimize their optical properties for infrared sensor application

Tailoring the physicochemical properties of the metallic multijunction nanolayers is a prerequisite for the development of microelectronics. From this perspective, a desired lower reflectance of infrared...

Electric field standing wave effects in internal reflection and ATR spectroscopy

We investigate electric field standing wave effects in the system semiinfinite incidence medium with high index of refraction/layer/vacuum, the latter being the semiinfinite exit medium. If the layer has...
