CRYSTALLINITYIn this research, acid hydrolyzed starch, B-typemicrocrystalline starch, and amorphous starch were prepared from natural corn starch. X-ray diffraction (XRD) and Raman spectroscopy were used to analyze the structure of these four types of starches. The Raman spectrum sca...
Raman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions. It is based upon the interaction of light with the chemical bonds within a material. Raman is a light scattering...
Raman spectroscopy is used for the identification of unknowns and in material characterization studies such as crystallinity, strain and polymorphism and is applicable to a wide variety of organic and inorganic materials.The relatively small spatial resolution provided by the visible laser (about 1 ...
Learn how Raman microscopy can evaluate material quality when manufacturing tool bits and ultra-hard coatings. Raman imaging can determine the uniformity of coatings like polycrystalline diamond (PCD) or TiN/TiO2. You can also use Raman spectroscopy to measure stress and crystallinity within coatings,...
Investigations of crystallinity and residual stress of cubic boron nitride films by Raman spectroscopy - art. no. 073201 With a spatial correlation model, a simple method was established to evaluate the crystallinity and stress of cubic boron nitride (cBN) films from the variation of linewidth and...
摘要: Raman spectroscopy has been used to investigate a series of poly(aryl ether ether ketone) (PEEK) films of differing crystallinity. Correlations have been made between relative intensity changes in the spectra and the crystallinity as measured by multiple internal reflection spectroscopy....
Right:Crystal structure of SiC polymorphs: 4H-SiC; 6H-SiC and 15R-SiC. Raman spectroscopy can easily differentiate between the 4H, 6H and 15R polymorphs of SiC. The controlled fabrication of SiC polymorphs is important for industrial semiconductor applications....
Raman spectroscopy is a nondestructive analytical technique based on the interaction of light and chemical bonds within materials. Raman spectroscopy can provide detailed information on a sample’s chemical structure, phase and morphology, crystallinity, and molecular interactions. For the application of ...
