Densities and Refractive Indices of Glycol Ether-Water Solutions.

Density, Viscosity, and Refractive Index for Water + 2-Butoxyethanol and + 2-(2-Butoxyethoxy)ethanol at Various Temperatures

“…A reasonable agreement was found among our experimental results and literature data. [21][22][23][24][25][26][27][28] The experimental results of densities, viscosities, and refractive indices for two binary systems: (1 -x) water + x C 4 E 1 and (1 -x) water + x C 4 E 2 as a function of mole fraction of C i E j , x, at temperatures ranging from (283.15 to 323.15) K are given in Tables 3 and 4, respectively. Note that the lower critical solution temperature (LCST) of the water + C 4 E 1 system is 322.15 K and that the system exhibits liquid-liquid coexistence when the system temperature is above its LCST.…”

Fabrication, splicing, Bragg grating writing, and polyelectrolyte functionalization of exposed-core microstructured optical fibers

“…In all measurements where liquids were measured, the far end of the fiber was sealed using the arc splicer to prevent liquid ingress into the MOF holes. The spliced EC-MOF fibers were immersed into refractive index solutions by vertically holding the fibers and inserting into sealed Pasteur pipettes containing isopropanol in water solutions, with the refractive index calculated based on measurements performed by Chu et al [50]. The reflection spectra contains multiple peaks due to higher order modes, however, the narrowest and strongest peak is generally the longest wavelength peak, which corresponds to coupling from the forward to the backward propagating fundamental mode.…”

Densities and Refractive Indices of Aqueous Solutions of Diethylenetriamine, and Triethylenetetramine, and Tetraethylenepentamine.

“…of the effect of chemical structure on density and refractive index, data have been obtained for aqueous solutions of diethylenetriamine, triethylenetetramine, and tetraethylenepentamine. The purification procedures and methods of analysis described by Chu and Thompson (4) were employed.…”
