Voigt deconvolution method and its applications to pure oxygen absorption spectrum at 1270 nm band

Tuning the C/N Ratio of C‐Rich Graphitic Carbon Nitride (g‐C3N4) Materials by the Melamine/Carboxylic Acid Adduct Route

“…Although perform- Chemistry-A European Journal ance of the C-rich C 3 N 4 material (MT6/1-550 sample) is lower than those of the well-known and optimized references, a photocatalytic behavior is evidenced and appears encouraging since there is probably room to enhance their properties for this application. It is also possible that the carbon content is too high and limits the light absorption of the carbonitride part compared to previous studies [50,51] where the N/C atomic ratio (determined by XPS) is in the range 1.19-1.35 whereas it is 0.93 and 1.61 for the studied samples.…”

“…Raman spectra were recorded using a Horiba Jobin Yvon HR800 apparatus working with a laser at 488 and 532 nm. I D / I G intensity ratio between D and G bands was estimated using Voigt function [51] . X‐ray photoelectron spectroscopy (XPS) was performed with a VG SCIENTA SES‐2002 spectrometer equipped with a concentric hemispherical analyzer.…”

“…I D /I G intensity ratio between D and G bands was estimated using Voigt function. [51] X-ray photoelectron spectroscopy (XPS) was performed with a VG SCIENTA SES-2002 spectrometer equipped with a concentric hemispherical analyzer. The incident radiation used was generated by a monochromatic Al Kα X-ray source (1486.6 eV) operating at 420 W (14 kV; 30 mA).…”

Concentration Dependence of Elastic and Viscoelastic Properties of Aqueous Solutions of Ficoll and Bovine Serum Albumin by Brillouin Light Scattering Spectroscopy

“…This phenomenology assumes that the concentration dependence of f and Γ B both increase smoothly with concentration according to f ( x ) = f R ( x ) + A 1 x 2 where f R is given by eq and Γ B ( x ) = A f ( x ) 2 + B x + A 2 x 2 where the A i are fit parameters, and f ( x ) is given by eq . Furthermore, the second order term in eq , A 2 x 2 , is a phenomenological extension to van’t Hoff’s law, as explained below. , From this, solute molecules in a dilute solution may be treated as ideal gas. As such, the line width is proportional to solution density, as expressed in the equation Γ B ( x ) ∝ 1 + c 1 ρ + c 2 ρ 2 + c 3 ρ 3 + · · · …”
