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 interactions of actinomycin D (ACTD) with the oligonucleotides 5'-CAAAGCTTTG-3', 5'-CATGGCCATG-3' and 5'-TATGGCCATA-3' were investigated by means of acid-base titrations and mole-ratio and melting experiments monitored by molecular absorption and circular dichroism (CD) spectroscopies....
The PDI of the nanoparticles represents the ratio of molecular weight (Mw) to number-average molecular mass (Mn)33. $$PDI = \frac{{M_{w} }}{{M_{n} }}$$ Raman spectroscopic analysis for HA-coated 5-FU in ThCs-NPs The Raman Spectroscopic instrument used by Thermo Fisher Co., Ltd...
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 ...
(intravalley), and D + D' (~2940 cm−1), a combinational scattering peak [7]. As has been previously reported, due to the strong dependence of graphene's Raman D peak on disorder in graphene, the level of disorder in graphene can be characterized using the ratio of Raman peak ...

(retention level 4) as well as PDMS pads created in-house (SYLGARD 184). The in-house PDMS pads were created by using a 10:1 ratio of silicon elastomer base to curing agent, respectively. These are then mixed thoroughly and left for ~1 h until any trapped air degasses from the ...
