An experimental study has been conducted to investigate the static and wind-on performance of two in-house-developed polymer-based pressure-sensitive paints. Platinum tetrakis (pentafluorophenyl) porphyrin and tris-bathophenanthroline ruthenium II are used as the luminophores of these two polymer-based pressure-sensitive paints. The pressure and temperature sensitivity and the photo-degradation...

Iron may be determined in biologic material by a wet-ash method employing chloric and nitric acids and a non-ash method using trichioroacetic acid treatment. Bathophenanthroline or bipyridyl is utilized for color development, performed in a buffered medium with mercaptoacetic acid as reductant. The wet-ash technic is best for estimating total iron in urine, and the non-ash technic for nonhemogl...

We developed a direct, simple, and sensitive procedure for the simultaneous colorimetric assay of iron and copper in serum, using sodium dodecyl sulfate-ascorbic acid to dissociate iron and copper from transferrin and ceruloplasmin, respectively. We also use a new water-soluble reagent, 2-(5-nitro-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol disodium salt (nitro-PAPS) and thioglycolic ac...

Serum iron may be directly measured without protein precipitation, by incubation in an acetate buffer in the presence of a reducing agent and sulfonated bathophenanthroline. Mercaptoacetic and ascorbic acids have proved to be suitable reductants. Values obtained for serum iron by this procedure show excellent correlation with a trichloroacetic acid precipitation technic. Bilirubin interference ...

As downstream purification and separation technologies progress towards raising the concentration of therapeutic-grade monoclonal antibodies (mAbs) in cell culture, processing has begun to face increased difficulty efficiently coping with such high immunoglobulin G (IgG) titers (≤25 mg mL−1). In current study, we demonstrate ability a non-chromatographic, ligand-free procedure recover almost qu...

The reactions of a zirconium salt with 1,2,4,5-benzenetetracarboxylate (btec), bathophenanthroline (Bphen) and thiocyanate ions were synthesized and studied by changing the mole ratio, the order of reactant and their pH. It is found that the coordination mode of btec acid depends on the control of reaction conditions. Monodentate, bidentate and bridging modes were investigated by FT-IR spectros...
