It is shown that in buffer medium of KHC8H4O4-HCl(pH 3.6), iron (Ⅲ) forms a blue complex with Br-BTAQ, the maximum absorption of the complex occurs at 635nm, and the apparent molar absorptivity is 3.26×104 L·mol-1·cm-1.Beer's law is obeyed in the range of 0-20f1g/25ml.
The system was used in quantification study on the tongue body and tongue coating for 927 patients. The results showed that each kind of tongue body and tongue coating had its corresponding quantitative RGB (three basic color, R is redness, G is greenness, B is blueness) characteristic.
By adjusting the thickness of the NPVBi and Alq 3, in the device with the thickness of 30 nm NPVBi and 20 nm Alq 3, a good blue color purity of electroluminescence, of which the highest luminance is 708 cd/m 2, and the maximum luminous efficiency is estimated to be 1.13 lm/W, respectively, is achieved.
Compared with crystal materials, the excitation and emission spectra of Bi4Si3O12 nanopowders indicated a blue shift.
The introduction of malonic acid dinitrile into the indicator reaction improves the sensitivity of the determination of copper and the contrast of the reaction in solution because of the formation of a blue product.
A blue form of a molybdoarsenic heteropoly acid formed on the adsorbent at any order of the adsorption of the reactants; however, the sensitivity of determination was higher if arsenic was adsorbed first.
A blue shift by 10 nm was recorded in the absorption spectrum of carotenoids form YM5-3 green mutant; considerable accumulation of neurosporine was revealed by HPLC and mass spectrometry.
The replacement of an ascidian (Styela rustica L.) fouling community by a blue mussel (Mytilus edulis L.) community was described for the White Sea.
Detergency, redeposition and optical brightener intensity are evaluated by reflectance, yellowness, blueness and ultraviolet fluorescence measured on a Gardner Larger Area Colorimeter after six soil-wash cycles.
It is simple in operation and gives excellent agreement with the visual appraisal by 27 observers of the whiteness for fabrics with different values for their fluorescence, lightness, yellowness or blueness, and redness or greenness.
Means of whiteness-blackness difference (ΔL*), redness-greenness difference (Δa*), andyellowness-blueness difference (Δb*) were 4.00, -1.28 and -7.53 for PN, and 2.54, -0.99, and -5.56 for OP, respectively.
The blue flower color of cineraria seems to be manifested solely by cinerarin, and it becomes likely that the caffeic acid involved in the molecule plays an essential role in the blueness of this pigment.
On the variation of solar radiation and blueness of the sky during the eclipse of June 30, 1954 at Athens
Fluorine-containing complexes exist only as 1,2- and 1,10-anthraquinoid structures, which are responsible for their blue color.
Colonies produced by this maneuver not only remained sensitive to ampicillin but were also incapable of blue color production on X-gal-containing media, thus demonstrating true blockade of pUC19 replication, rather than antisense activity.
This test is based on the ability of the live scale enzymes to react with iodine, yielding iodine products which in turn are unable to give the blue color reaction with starch.
Acetaldehyde reacts with sodium nitroprusside producing a blue color.
The primary red-green-blue color coordinate system is first transformed into the saturation-hue-brightness color coordinate system.
