Relations between some Physicochemical Properties of Reactive Dyes and their Behaviour in Padding Processes

Meetings of the Scottish Region, held in the St Enoch Hotel, Glasgow, on 16th February 1965, Mr B. W. Mills in the chair; and of the Manchester Region, held at the Manchester Literary and Philosophical Society on 18th February 1965, Mr F. V. Davis in the chair Experimental results are presented which show that the members of any given range of reactive dyes have a diffusion coefficient D and an exhaustion value E which are roughly in inverse proportion to each other. Metal–complex dyes (1: 1 and 1: 2) and phthalocyanine metal complexes, however, show characteristic deviations in behaviour. The significance of D and E in the padding, intermediate drying, and fixation of reactive dyes is elucidated. The theory of the padding process is discussed and the relationships between D and E and the ending behaviour are demonstrated. A new test for assessing the tendency to ending is described.     

Physicochemical Properties, Volatile Compounds and Phospholipid Classes of Silver Carp Brain Lipids

Large amounts of utilizable by-products are produced concomitant with silver carp processing. The lipids from fish brain contain considerable essential fatty acids which however have seldom been studied. In this study, the lipids extracted from the brain of silver carp exhibited good physicochemical properties. Forty volatile compounds were identified, of which hydrocarbons and aromatics predominated. The ratios of polar lipids and phospholipids to total lipids were 22.73 and 10.95 % respectively. Phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylserine (PS) accounted for 83.9 % of the phospholipids. Major fatty acids of neutral lipids, polar lipids, PC, PE and PS differed significantly. PE had the most polyunsaturated fatty acids (PUFA), while PC, PE and PS were rich in docosahexaenoic and eicosapentaenoic acids. Moreover, the ratios of fatty acids were considered to be reasonable due to high levels of n3 PUFA. The lipids from silver carp brain have been demonstrated to be healthy and nutritious. The results herein confirm that silver carp brain lipids are a commercially and industrially feasible prospect.

Synthesis and Physicochemical Properties of Nanocrystalline Silicon Carbonitride Films Deposited by Microwave Plasma from Organoelement Compounds

Nanocrystalline films of a ternary compound, namely, silicon carbonitride SiC_xN_y, are prepared by plasma-enhanced chemical vapor deposition at temperatures of 473–1173 K with the use of a complex gaseous mixture of hexamethyldisilazane Si₂NH(CH₃)₆, ammonia, and helium. The chemical and phase compositions and the physicochemical properties of the films are investigated using IR, Auger electron, and X-ray photoelectron spectroscopy; ellipsometry; synchrotron X-ray powder diffraction; electron and atomic-force microscopy; microhardness measurements with a nanoindenter; and electrical measurements. Correlations of the composition of the initial gas phase and the synthesis temperature with a number of functional properties of the SiC_xN_y silicon carbonitride films are revealed.Original Russian Text Copyright © 2005 by Fizika i Khimiya Stekla, Fainer, Kosinova, Rumyantsev, Maksimovskii, Kuznetsov, Kesler, Kirienko, Han Bao-Shan, Lu Cheng.

Synthesis and Antimalarial Properties of Streptocyanine Dyes

Several streptocyanine dyes were synthesized that contain polymethine chains of varying length. Their in vitro antimalarial activities were evaluated against the virulent P. falciparum parasite. In addition to the influence of polymethine chain length, the effects of structural modifications at nitrogen end groups, para substitution of the phenyl groups, and counter‐anions were studied. The most potent antimalarial activities were found for heptacarbon chain streptocyanines, with an IC₅₀ value of 60 nM . Interestingly, most of the compounds were less cytotoxic toward the mammalian cells tested. The best selective toxicity profiles were found for pentacarbon chain streptocyanines, which have a good in vitro specificity index.
