Identifying Pseudorutile and Kleberite Using Raman Spectroscopy

چکیده
Pseudorutile and kleberite are intermediate minerals formed during alteration of ilmenite to rutile. They difficult identify, as both have a range chemical composition occur small crystals commonly mixed with other minerals. Reference samples large pseudorutile kleberite, published X-ray diffraction analyses, were analysed establish characteristic Raman spectra. produced goethite-like spectrum but shift increased wavenumber. It has bands peak positions at 234, 302, 402, 546, 617, 713 816 cm−1 OH stretching over the interval 3390–3350 cm−1. The 402 806 most intense. Kleberite similar spectrum, 10–30 greater in bands.

Identifying and localizing intracellular nanoparticles using Raman spectroscopy.
Raman microscopy is employed to spectroscopically image biological cells previously exposed to fluorescently labelled polystyrene nanoparticles and, in combination with K-means clustering and principal component analysis (PCA), is demonstrated to be capable of localising the nanoparticles and identifying the subcellular environment based on the molecular spectroscopic signatures. The neutral na...

Background: Carious lesions are formed by a complex process of chemical interaction between dental enamel and its environment. They can cause cavities and pain, and are expensive to fix. It is hard to characterize in vivo as a result of environment factors and remineralization by ions in the oral cavity. Objectives: The development of a technique that gives early diagnosis which is non-invasi...
