Excess volumes of mixing, VE, for binary mixtures of eyelohexanone with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-dodecane, n-tetradecane, and n-hexadecane at 25 °C were determined from the precise and accurate experimental density data. The sign and magnitude of VE were discussed in terms of the strength of the unlike interactions present in the binary mixtures.Excess volumes of mixing of equimolar concentration [Formula: see text] were also obtained. Attempts were made to interpret [Formula: see text] in terms of the size and polarity of the constituent molecule. The two effects could not be separated, but a good linear relation between [Formula: see text] and the solubility parameter was found.

Molar excess volumes for the binary mixtures of cyclohexanone with benzene and some monosubstituted benzenes, namely, toluene, ethylbenzene, isopropylbenzene, tertiary butylbenzene, chlorobenzene, bromobenzene, iodobenzene, N,N-dimethylaniline, nitrobenzene, benzaldehyde, and benzonitrile have been calculated from the precise and accurate experimental density data at 298.15 K over the entire composition range. The results have been discussed in terms of the strength of molecular interactions in the binary mixtures.

Densities of binary mixtures of 2-methoxyethanol (2-MeO-EtOH) and 2-ethoxyethanol (2-EtO-EtOH) with hexylamine (HLA), diethylamine (DEA), triethylamine (TEA), tert-butylamine (TBA), aniline (ANL), and benzylamine (BLA) have been determined at varying compositions of the alkoxyalkanols at 298.15 K. The excess molar volumes, VE, of the binary mixtures were calculated from the experimental density data of the mixtures and the component single solvents. The calculated excess molar volumes were fitted into the Redlich-Kister polynomial to obtain the fitting coefficients and standard deviations. The excess molar volumes of the binary mixtures of all the solvent systems investigated were negative over the entire range of the solvents composition. The negative values were attributed to stronger hydrogen bond formations between the unlike molecules of mixtures than those between the like molecules of the pure components. The magnitude of the excess molar volumes of the binary mixtures of 2-methoxyethanol and the aliphatic amines were in the order TBA > TEA > DEA > HEA. For the two aromatic amines, the magnitudes were in the order BLA > ANL. For binary mixtures of the amines and 2-ethoxyethanol, the magnitudes were in the order DEA > TEA > TBA > HEA at compositions where the mole fraction of 2-EtO-EtOH was ≤0.5 and TBA > TEA > DEA > HEA above 0.5 mole fraction of 2-EtO-EtOH.

Sensitive Determination

A novel Nafion/PMB/G/GCE was prepared by firstly electro-polymerization of MB to G/GCE and then coating Nafion on PMB/G/GCE. The as-prepared modified electrode combining the advantages of Nafion, methylene blue and G was employed for the sensitive detection of rutin. The results showed that the peak current of rutin obtained on Nafion/PMB/G/GCE was obviously high compared to bare electrode and G/GCE. Under the optimized value of pH, which was pH 3.0, peak current of rutin had good linear relation with the scan rate. At the same time, peak current increased linearly with increasing concentration of rutin. The linear range was from 5×10-7 mol/L to 1.2×10-5 mol/L, and the detection limit was 9.5×10-8 mol/L

Input Control

At the base of development of ordnance, the study of model machine of controllable micro emitter definitive direction angle and pitch angle is advancing, which definitive direction angle and emissive angle is very important. By theoretical and empirical equation analysis, it may deduce dynamics equations about load flux of micro fluid controlling direction angle and emissive angle in micro emitter. After linearization, transfer function may be calculated. When deviation is very small, output and input control present good linear relation. So make emissive process control easy.
