A new flow method has been employed to obtain critical point and vapor pressure data at high temperatures for four compounds: squalane, toluene, ethylbenzene, and styrene. This new flow method allows the determination of reliable critical points and vapor pressures for thermally unstable or other...
toluene vaporactivated carbonbreakthrough curvedeactivation modelToluene vapor was adsorbed in a laboratory‐scale packed‐bed adsorber using granular activated carbon (GAC) at constant pressure (101.3kPa). The adsorber was operated batchwise with the charge of GAC in the range of 2–4g to obtain ...
The problem concerning the determination of asphaltene molecular weight has been critically investigated. A size exclusion chromatography (SEC) analytical method has been developed using innovative calibration standards. The obtained results have been compared with those derived from vapor pressure osmometry ...
Vapor-liquid equilibrium relations were measured for binary systems made of N,N-dimethylformamide with acrylonitrile or trichloroethylene at 98.66kPa by the dew-bubble point temperature method. Combining the dew point temperature curve and the bubble point one, vapor-liquid equilibrium relationships were ...
The formation of complex structures in thin films is of interest in many fields. Segregation of polymer chains of different molecular weights is a well-known process. However, here, polystyrene with bimodal molecular weight distribution, but no additiona
of its saturation vapor pressure. According to the theory of like dissolves like, we further fabricate a polymer/AIE microwires array derived from designable polyethersulfones, through regulating their side chains, to distinguish similar organic vapors of benzene and toluene. Both experimental and ...
These are some examples of the ubiquity of glasses in nature and technology. There are several routes to produce glasses: fast-quenching6, cryo-milling7 or high pressure quenching8, among others. However, the discovery of ultrastable glasses (USG) by vapor deposition (VD) represents a milestone...
(red curve of FIG. 7c). The observed red-shift at high RH is the largest ever observed for a BS for moisture sensing applications. Note that besides the unique colour changes also the ultrafast response time and the high reproducibility and cyclability of the Bragg stack device10is ...
1. Regression analysis yielded a power curve with the best fit. An alternate method of analyzing the data is to plot MVTR as a function of reciprocal film thickness resulting in a linear relationship between the two variables (FIGS. 2-6). The slope of the linear regression line with the ...
