21231/54. Class 98(2) An exposed multilayer or multi-particle differentially sensitized gelatino-silver halide material containing colour formers is treated with an alkaline solution of formaldehyde and an inorganic sulphite after colour development, treatment which arrests development and hardens the ...
Changes enacted by water are much faster than those by ethanol, in spite of ethanol's more rapid spread across the elytral surface. Moreover, the beetle's photonic structure is enclosed by a thin scale envelope preventing direct contact with the liquid. Here, we note the presence of sodium...
where as glucose, Ascorbic acid, Cysteine, Cetyl-trimethyl-ammonium bromide (CTAB), Sodium molybdate, Biotin, KNO3, NaNO2, folic acid and 1-amino-2-naphtho-4-sulfonic acid (ANSA) does not shows influence on to the process, but, some of them showed inhibitory effect toward the decolourizatio...
Leaves of WT and ygl8 was collected from 3-week-old plants grown in the experiment filed under natural conditions and fixed in primary fixative solution (3.5 % glutaraldehyde) and then post-fixed for 2 h with 1 % osmium tetroxide after washing with 0.1 mol L−1 PBS buffer. Tissues were...
To obtain a yellow, transparent pigment, a 5-25% aqueous suspension of flaky substrate 45 is prepared, which contains in the form of a solution 10-150 hours, mostly about 30-90, iron salt, 1-50 hours, mostly 2-30, salts magnesium and Yu-400 hours, mainly 30-270, urea and 5Q, in...
bisulphite and potassium bromide to convert silver chloride to silver bromide and then in a solution containing potassium bromide, sodium acid phosphate and thiourea together with a specified red, yellow or blue acid dye, and washed in still or gently flowing water to clear non-image portions of...
After exposure and colour development in an aqueous solution of sodium hexametaphosphate, sodium bisulphite, 4 - diethylaminoaniline, sodium carbonate, hydroxylamine hydrochloride, and KBr, the excess developer is washed out, and the film is treated in an aqueous solution of KI, acetic acid, and ...
These isotherms have been fitted to Langmuir, Freundlich, and Dubinin models and the resulting model parameters, which are needed for the prediction of multicomponent adsorption equilibria, are reported. Predictions obtained from the extended Langmuir predictive model and the ideal adsorbed solution (IAS...
Alternatively the developing solution may be covered with a layer of benzene or petroleum, the exposed film being passed into the developing solution without contact with this layer. Excess of sodium hydrosulphite in the preparation of developing solutions may be rendered inactive by addition of ...
The blue component layer is then exposed to blue light and developed to a yellow picture, the colour filter is bleached with a solution of sodium hydrosulphite and potassium bromide, and the green component layer then exposed and developed to give a purple image. The silver is removed by ...
