The rate constants of oxidation of hydrocarbons (RH) were found to be unusual bell-shaped functions of the volume ratio between liquid and gas phases in a reactor.
They are (i) the volume ratio of germane to silane, (ii) the volume ratio of silane and germane to diborane and phosphine, (iii) substrate temperature, and (iv) annealing temperature.
The volume ratio of the phases depends on the temperature and the magnetic field.
Chromatographic analysis was carried out on Zorbax C18 column (150 mm × 4.6 mm, 5 μm) with a mobile phase of mixture of water, acetonitrile and methanol in the volume ratio of 50:40:10, at a flow rate of 1.0 mL min-1.
Following a controlled preparation, it was determined that the capsule mechanical stability was largely dependent on the volume ratio of the capsule over the membrane.
The measurement of pressures in shock waves by volume-type sensors
Nickel-polystyrene composite materials produced by the chemical deposition of nickel on polystyrene beads exhibit high conductivity at a nickel concentration of less than one percent by volume.
Acetonitrile and diethyl ether mixtures (10 : 4-6.5, by volume) were proposed as eluants.
The isotope exchange was performed at 100°C in the dioxane-triethylamine mixed solvent (9: 1 by volume).
The electrochemical reduction of carbonyl-containing methanofullerenes is studied by methods of cyclic voltammetry and ESR with in situ electrolysis in the environment of 0.1 M Bu4NBF4 in o-dichlorobenzene-dimethylformamide (3:1 by volume).
The percolation thresholds of PS/PPy and Zn-SPS/PPy composites were 6.2% and 2.7% of the volume fraction of PPy, respectively, much lower than the theoretically predicted value of 16%.
The numerical results show that the values of equivalent plastic strain and void volume fraction increase with time.
The ductile β phase with a volume fraction of about 30% possesses a developed dendritic morphology.
With the increase of HA volume fraction, the Ti-HA reaction could be divided into three stages including stable initiation, stimulating term and re-stabilization according to the quantitative characteristics of the ceramic phase.
The necessary pole figures data can be collected holistically by the X-ray area detectors, after which the volume fraction of the texture components in Gaussian forms is obtained.
