The experimental spectra recorded with several excitation laser lines have been compared with the results from a theoretical analysis of the resonant Raman response based on density functional theory calculations. Compared to previous investigation the spectra show better signal-to-noise ratio, which ...
The difference in the chemical structure of acetylated starch and retrograded acetylated starch was clear on the H1 spectra (Fig. 2). The rate of methyl protons of acetyl groups of acetylated native starch placed at C-3, C-2 and C-6 gave the ratio of 1.0:5.5:10.8 (Fig. 4). Retrograd...
The Deltadelta values evaluated by (1)H NMR spectroscopy also support their aromatic nature. The protonated forms of octaphyrins bind TFA anion in a 1:2 ratio. The TFA anions are located one above and below the plane of the octaphyrin macrocycle and they are held by weak electrostatic NH...
After device fabrication we characterised our films through a combination of optical and Raman spectroscopy17,18,19,20, electron transport, atomic force microscopy (AFM) and scanning electron microscopy (SEM) to identify the surface roughness and film thicknesses (SeeSupplementary Notes4,6and7). We...
More in detail, the refinement based on the residual Fc–Fo difference map allowed us to estimate that canonical and reversed hemes are present in a 29:71 and 33:67 ratio in MON1 and MON2, respectively. The double heme insertion in both monomers leads to somewhat different His64–Fe–His...
Ensuring stability of carotenoids in commercial nutraceutical formulations Several pieces of evidence have cited that it is not possible to obtain the two integral macular pigments, lutein and zeaxanthin, in optimal ratio from diet (121, 122). Both bio- accessibility (total amount of absorbable ...

Line shift, line asymmetry, and the $\\mathsf{^6}$Li/$\\mathsf{^7}$Li isotopic ratio determination TerraSpark Geosciences~R says it has developed an application adapter that will connect its Insight Earth solution to the OpenSpirit~R integration platform... R.,Cayrel,M.,... - 《Astr...
When the reactants ratio is changed to 1:12, TG curve of the prepared AAC-6 heterojunction in Fig. 1f suggests that the first platform of weight loss is significantly reduced from 15.1% to 2.8% compared pure Ag2CO3. Therefore, the Ag2CO3 contents in AAC-6 sample obviously decrease in...
Strain represents the change in length or angle under applied stress. This includes stretching, compression, bending and torsion. The sensitivity of these devices can be appraised by gauge factor (GF), which can be expressed as the ratio of relative change of electrical resistance R to the ...
