This paper proposes an algorithm of material auto-identification, which makes use of machine learning methods to analyze Raman spectra. Firstly, a universal method of spectral feature extraction is designed to automatically process Raman spectra after the background subtraction. Secondly, the extracted ...
Beginning: 12/13/22 Location: Online During this webinar, we will explain impact of processing on Raman spectra and the solutions for Raman image analysis, including multivariate analyzes.
Bulk solutions (organic and aqueous) typically require just a simple cuvette cell holder and collection/focusing optics. It is also possible to analyze directly into sample bottles and vials using confocal optics, which minimizes the contribution of the glass container to the spectrum. Gas samples ...

Make sure to include a discussion of electrons in your answer. How can the presence of an ion in a solution be detected? If you were given an unknown solid to analyze for certain elements, what instruments would you use, and how would you explain the theory behind ...
To break through this principle limitation, there are several solutions. Melucci et al. [37] introduce a non-destructive ATR-FTIR method to analyze the biogenic silica in marine sediments which is a new quantification approach. Neves et al.’s study [38] shows an ATR-FTIR method to detect...
general monograph 2031 for monoclonal antibodies allows for many techniques to analyze a required attribute of a BTP. An example of this is given in Table V for the Charged Variants test in the infliximab concentrated solution monograph that became official in January 2019. Two companies’ ...
STEM-Electron Energy Loss Spectroscopy (EELS) was employed to analyze the chemical bonding within the oxide film. Figure 4b shows the near-edge structure of the Al-L2,3 edges obtained from metallic Al and the Al-containing oxide. The characteristic of the EELS signal fits well with reported ...
To gain deep mechanistic insights, we next analyze different phonon modes and carrier density effects on spin relaxation through examining spin-resolved e-ph matrix elements. In Fig.2, we compare the contribution of different phonon modes toτsandτp. First, we find that at a very lowT- 4 ...
"Field workers could put a blood sample on a slide, take a picture and send it to specialists to analyze," said Sebastian Wachsmann-Hogiu, of the university’s department of pathology and laboratory medicine and the lead author of the research that led to the smartphone’s adaptation to ser...
