RRUFF PROJECT: DEVELOPING AN INTEGRATED DATABASE OF RAMAN AND INFRARED SPECTRA, X-RAY DIFFRACTION AND CHEMISTRY DATA FOR MINERALS 来自 gsa.confex.com 喜欢 0 阅读量: 322 作者: PR Mooney 摘要: Raman spectroscopy was first documented in 1928 when Sir C. V. Raman wrote: "When a beam of ...
in a non-invasive, label-free manner4,5,6. Fig. 1: Spatially-unaware spectra from Raman analysis show distinct clustering. a Data analysis workflow, starting from data acquisition using a confocal Raman microspectroscope. b Data handling, transformation and correction. Biologically relevant spectrum...
This approach is used, e.g., in the WURM project146,186, which hosts a number of simulated Raman spectra, including electroceramics. The same approach is used in a high-throughput study recently introduced by the Materials Project team187 and yet another online database188. The limitations of...
Numerous publications [36,43,50,113] and online databases (for example, the Infrared & Raman Users Group (IRUG) - http://irug.org;“Pigments Checker Free Spectra Database” https://chsopensource.org/pigments-checker/ [114], etc.) are available. More practical information about Raman ...
You can easily identify materials with Renishaw's Inorganic Materials and Minerals spectral database. The high spectral resolution of the inVia confocal Raman microscope enables you to differentiate material with very similar Raman spectra, such as polymorphs. ...
In the diagnosis of skin disease, PCA can be employed to reduce the dimensionality of the features and select the optimal set. CT-RamSES can be used to process Raman spectra as well as for PCA multivariate analysis and data visualization, while the MATLAB calculation platform can be used durin...
One Raman spectrometer was used to detect the Raman signals of particles and the data were imported into the library software which automatically analyzed the characteristic peaks and peak intensities of the particle spectra with a similarity (classical) algorithm, and compared them with those in the...
database was established with 50 spectra per tissue sample, and a total of 12,000 spectra were obtained from 120 pairs of liver tissue samples. The spectral data ranged from 500 to 2000 cm−1with 889 one-dimensional float data. A binary classification model was built to classify liver ...
data inputs, but as healthy when using the FP feature set. Spectra s1 and s2 (rendered in gray in Fig.4) are most similar to the average healthy spectrum. The similarity is evident both to qualitative visual inspection and the two spectra appear near the center of the k-means cluster ...
