The thermodynamic functions for square-well gases evaluated till the third virial coefficient are investigated at an isobaric process. Some thermodynamic functions are analytically expressed as functions of intensive variables, temperature, and pressure. Some thermodynamic quantities for H2O are calculated numerically and drawn graphically. In critical states, the heat capacity, thermal expansi...

We fabricated triisopropylsilyl (TIPS) pentacene organic thin-film transistors (OTFTs) by inkjet printing method and investigated their electrical properties. The film morphology of TIPS pentacene layer and the field-effect mobility of OTFTs were greatly affected by choice of the solvent which TIPS pentacene was dissolved in. Especially the boiling point of a solvent was a critical factor that ...

Surface wettability is recognized as playing an important role in pool boiling and the corresponding heat transfer curve. In this work, a systematic study of pool boiling heat transfer on smooth surfaces of varying wettability (contact angle range of 5° - 180°) has been conducted and reported. Based on numerical simulations, boiling curves are calculated and boiling dynamics in each regime are ...

Gas chromatographic (GC) retention indices are useful for reviewing mass spectral library searches for the tentative identification of organic compounds. If the known GC retention index (RI) of a compound that ranks high on the (gas chromatography-mass spectrometry) GC-MS library search “hit list” matches the RI of the unknown, there is a strong presumption that a correct identification has bee...

Some thermodynamic quantities for the Stockmayer potential (12, 6, 3) with a hard core are analytically evaluated at an isobaric process. The parameters of polar gases for 16 substances are obtained. Also some thermodynamic quantities for H2O are calculated numerically and drawn graphically. The inflexion point of the length L corresponds physically to a boiling point. L indicates the liquid ph...

morphological changes in polyvinyl butyral (pvb) electrospun nanofibres can be acquired by preparation of pvb spinning solution in different solvents.  accordingly, three solvents, including ethyl alcohol, n-butanol and isopropanol, with diverse physical properties (e.g. boiling point, density, dipole moment and dielectric constant) were used to prepare polyvinyl butyral (pvb) spinning solution...

An Agilent Simulated Distillation (SIMDIS) system is described for quality control and monitoring of refinery processes. The system uses an Agilent 6890N gas chromatograph (GC) equipped with a programmable temperature vaporizer (PTV) inlet designed specifically for high temperature analysis. A simulated distillation software program that couples with the Agilent GC ChemStation provides an easy-...

The combined effect of pore size and pore volume on the equilibrium adsorption capacity and the adsorption kinetics for a series of normal alkanes is determined. The selected adsorbents, activated carbon fibers (ACFs) and air activated phenolic fibers (AAPFs), possess a range of micropore sizes and have been thoroughly characterized in past work. For the normal alkane series, the lower surface ...

In this study, the use of the three-layer feed forward neural network has been investigated for estimating of infinite dilute diffusion coefficient ( D12 ) of supercritical fluid (SCF), liquid and gas binary systems. Infinite dilute diffusion coefficient was spotted as a function of critical temperature, critical pressure, critical volume, normal boiling point, molecular volume in normal boilin...
