SPECTRAAMMONIASURFACEActivated carbon is typically being used as an adsorbent material for various hazardous materials. It is common to impregnate the carbon with metal oxides in order to improve its adsorbing capabilities to polar hydrophilic compounds. Exposure of activated carbon to humidity causes ...
Performance of Raman image-activated cell sorting We validated the basic performance of the RIACS as follows. First, we performed high-purity enrichment of polymer particles (see “preparation of polymer particles” in the Methods section for details). Figure 2a shows SRS spectra of polystyrene (...
The carotenoid bands in Raman spectra of photosynthetic microorganisms utilizing (13)CO(2) shifted when compared to the spectra of cells utilizing (12)CO(2). Here, a mixture of (12)C- and (13)C-cyanobacterial cells were counted using a microfluidic-device-based Raman-activated cell counting ...
Raman spectroscopy of carbon nanohoops AbstractWe present the Raman spectra for [n]Cycloparaphenylenes ([n]CPPs) of different sizes. A plethora of Raman modes are observed in these spectra, incl... H Chen,MR Golder,F Wang,... - 《Carbon》 被引量: 127发表: 2014年 Infrared and Raman ...
Raman spectra are reported from single crystals of graphite and other graphite materials. Single crystals of graphite show one single line at 1575 cm1. For the other materials like stress‐annealed pyrolitic graphite, commercial graphites, activated charcoal, lampblack, and vitreous carbon another lin...
图5 各煤样Raman光谱特征Fig.5 Raman spectra are composed of first-order regions, with the main peaks suggested (graphite G peak and D1 to D4 defect-activated peaks), and corresponding second-order regions resulting from overtone scattering 表3 各煤样Raman光谱参数 Table 3 Raman spectroscopic par...
Raman spectroscopic investigation also has some limitations, including the requirement to acquire sufficient spectra per skin sample to accommodate different cells’ variations. Currently, consented approaches are lacking to sampling size evaluation required to capture the targeted level of diversity and compl...
Figure 1c plots the Raman spectra, measured as described in Methods, in the spectral ranges of the C, G and 2D bands, for an excitation energy Eex ¼ 1.96 eV. The spectra are normalized to I(G) of the SLG sample. The 2D band of t(1 þ 3)LG can be fitted using the peak ...
