Using the literature values of the two phases ( Table 1 ) it can be found that the theoretical slope for the mixing rule for this binary composite is equal to 5.5 × 10 −6 °C −1 .
The linear fitting results of the experimental coefficients (α

The spectral features depicted in Fig. 2a are typical for petro-diesels and identical spectra were reported in literature [ 14 ]. The aim of depicting MIR spectra of samples 8 and 12 is due to the samples having high variations in their elemental

insufficient detail and XRD is unable to reveal all the structural substitutions, particularly for very fine crystal sizes that produce peak broadening, and so this will lead to variability in values stated in the literature.
A method for estimating the vapor-liquid equilibria of binary liquid solutions using an Accelerating Rate Calorimeter (ARC)
is described. ARC provided data in the ranges: (0–14) kPa and (300–450) K. The experimental PTx data were reduced to partial
pressures and vapor phase compositions using Barker's method. The well-known system, benzene/cyclopentane, was selected to
evaluate the ARC method. GC-headspace analysis confirmed the vapor phase compositions. Both GC and ARC data on the vapor phase
agree with literature data to within ±0.0085 mol fraction units. Experimental pressure data agree with literature data to
within ±2 kPa. Model pressure data agree with literature data to within ±1.5 kPa. Also described is the high-pressure VLE
of the phosgene-chlorobenzene binary at 448 K.
UV-Vis spectra of solutions in solid-aqueous phase equilibrium with UO3·2H2O(s) and 0.03 kPa CO2 partial pressure are quantitatively analyzed by single component spectra of hydrolysis species UO
. From the deconvoluted spectra, single species concentrations are obtained and interpreted by various statistical methods.
Relationship of UV-Vis data to fluorescence spectroscopic analysis of the same system is discussed. Calculation of thermodynamic
quantities gave consistent results, both within experimental data and with results from solubility studies and spectroscopic
analysis from literature. A reinterpretation of some literature data is proposed.

Tri-iso-amyl phosphate is an alternate solvent, proposed in literature as an alternate to the PUREX/UREX solvent tri-n-butyl
phosphate for better physical properties. Its PVT properties and accurate expression for estimation of its vapour pressure
are not available in the literature. Recently PVT properties of TiAP were estimated by authors and its vapour pressure was
measured in a ASTM certified vapor pressure measurement system at temperatures ranging from 273.15 to 373.15 K. In this paper,
results of these studies are presented.
It has been observed that the intensities of the gamma-rays emitted in the alpha-decay of 245Cm reported in the literature result in calculated concentrations that do not agree with those obtained via other methods.
In this work, a 245Cm sample was chemically isolated from a sample of 249Cf, and the gamma-ray intensities were measured relative to the alpha-particle emission rate of the resulting source; there
is a systematic bias relative to the literature intensities of approximately 8%. In addition, gamma-rays that have never before
been observed in the decay of 245Cm are placed in the level scheme of the decay product, 241Pu.
The independently measured catalogues of two single comparator methods for standardization in INAA, i.e., thekZn-and thek0-method, were compared. Many reactions were listed only in thekZn-catalogue; in these cases other literature data were used to supplement thek0-catalogue. The agreement between thekZn-and thek0-catalogue was found to be much better than the agreement between thekZn-catalogue and other literature data. It is therefore suggested to use the convertedkZn-catalogue as a supplement of the previously publishedk0-catalogue.
k0-Factors and related nuclear data are tabulated for 112 radionuclides of interest in (n, ) reactor neutron activation analysis. Whenever relevant, critical comments are made with respect to the accuracy of literature data for e. g. isotopic abundances, half-lives, absolute gamma-intensities and 2200 m · s–1 (n, ) cross-sections. As to the latter, a comparison is made with the values calculated from the experimentally determined k0-factors, by introduction of selected literature data for the input parameters.
