Raman spectroscopy of boron carbides and related boron

Raman spectroscopy is also useful in characterizing methods of preparation of boron-based materials. For example, inclusions of carbonaceous material in the boron carbides can be detected by the presence of two broad Raman lines 1370 and 1580 cm-1.

Purity and Defect Characterization of Single

We investigated the purity and defects of single-wall carbon nanotubes (SWCNTs) produced by various synthetic methods including chemical vapor deposition, arc discharge, and laser ablation. The SWCNT samples were characterized using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and Raman spectroscopy. Quantitative analysis of SEM images suggested that the G-band Raman

Evaluation of the individualization state in single

N2 - We report a method for characterizing the individualization of single-walled carbon nanotubes (SWCNTs) in a solution based on absorption, Raman and photoluminescence spectroscopy. In the first van Hope transition interband (S11), we selected two distinct peaks and introduced kurtosis as a quantitative value for representing the sharpness and magnitude of the peaks.

Characterizing various types of defects in nuclear

2015/12/1Raman spectroscopy has proved to be an appropriate technique to probe defects in carbon-based materials owing to its high sensitivity, most often focused on the commonly used I D /I G parameter. However, this ratio may be activated by various types of defects and in a completely independent manner.

Characterizing metabolic stress

Raman spectroscopy has been proven a powerful analytical technique for the analysis of biological materials. It uses monochromatic light to provide a qualitative measurement of the biochemical composition of the biological specimen ( Butler et al., 2016 ) and gives distinctive signals from macromolecules (i.e., proteins, lipids, carbohydrates, and nucleic acids) ( Das Agrawal, 2011 ).

C

Carbon-based nanomaterials have emerged as a subject of enormous scientific attention due to their outstanding mechanical, electrical and thermal properties. Incorporated in a polymeric matrix, they are expected to significantly improve physical properties of the host medium at extremely small filler content. In this work, we report a characterization of various carbonaceous materials by Raman

RS is one of the most powerful tools for characterizing

RS is one of the most powerful tools for characterizing carbon materials, because the spectral shape exhibits wide varieties corresponding to the different forms of the carbon, and thus reveals fine structural information [22]. A typical DLC film shows a Raman band in the range between 1000 and 1800 cm-1..

Employing Raman Spectroscopy to Qualitatively

This review article discusses the application of Raman spectroscopy to rapidly determine if large quantities of carbon impurities are present in nanotube materials. Raman spectra of crude SWNT materials reveal tangential bands between 1500–1600 cm -1, as well as a broad band at ~1350 cm -1, attributed to a convolution of the disorder-induced band (D-band) of carbon impurities and the D

Characterization of Metal/Carbon Multilayers by

Laser Raman spectroscopy has been found to be useful for characterizing amorphous semiconductor multilayers, especially the interfaces of multilayers. Recently, we have extended this technique to the characterization of magnetron sputtered multilayers commonly used as reflectors in soft x-ray optics. Unlike the multilayers previously studied which contained only semiconductors and dielectrics

Operando Raman Spectroscopy

Multi-wavelength Raman spectroscopy is powerful in characterizing the structural heterogeneity of functional materials through resonance Raman. The structural information can be both surface adsorbed species and the substrate (catalyst) under operando conditions.
