Improvement in PBI method.
THERE ARE A NUMBER OF VARIATIONS in the methods described in the literature for the procedure by incineration for the determination of protein bound iodine (PBI) (1, 2). Most of these are simple variations of the basic ones described earlier in the literature. After incineration there remains an insoluble portion when the residue is treated with 2N HC1, 7N 112S04, and H20. It appears to be unbu...
متن کاملThe prevention of cross-contamination in PBI determinations.
‘THEUSE of heavy aluminum foil in our ashing procedure for PB1 (1), introduced 3 years ago, has proved extremely successful in preventing cross-contamination. A Temco double-door muffle furnace is used for which three steel buckets were made; small buckets, 4 in. wide, 6 in. long, and 6 in. deep, and one large bucket, 6 in. wide, 8 in. long, and 6 in. deep. A steel shovel was made to aid the te...
متن کاملHigh-Temperature Steam-Treatment of PBI, PEKK, and a PEKK-PBI Blend: A Solid-State NMR and IR Spectroscopic Study
Blends of polyaryletherketones (PAEK) with polybenzimidazole (PBI) are of commercial interest due to their improved upper service temperatures and wear properties when compared with the PAEK analogs examined to date. The retention of properties of the PBI component generally thought to be disadvantageous in more thermally or chemically aggressive environments is not well understood, nor are the...
متن کاملControlling Photoconductivity in PBI Films by Supramolecular Assembly.
Perylene bisimides (PBIs) self-assemble in solution. The solubility of the PBIs is commonly changed through the choice of substituents at the imide positions. It is generally assumed this substitution does not affect the electronic properties of the PBI, and that the properties of the self-assembled aggregate are essentially that of the isolated molecule. However, substituents do affect the sel...
متن کاملAn Improvement of Steerable Pyramid Denoising Method
The use of wavelets in denoising, seems to be an advantage in representing well the details. However, the edges are not so well preserved. Total variation technique has advantages over simple denoising techniques such as linear smoothing or median filtering, which reduce noise, but at the same time smooth away edges to a greater or lesser degree. In this paper, an efficient denoising method bas...
