In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

Nanocrystalline lead selenide (PbSe) thin films were prepared on glass substrates by a chemical bath deposition method, using sodium selenosulfate (Na(2)SeSO(3)) as a source of Se(2-) ions, and lead acetate as a source of Pb(2+) ions. Trisodium citrate (TSC) was used as a complexing agent. PbSe films were prepared at various deposition temperatures while the pH value was kept fixed at 11, and t...

The Turkevich synthesis method of Au nanoparticles (AuNPs) was adopted for direct fabrication of SiO2@Au and TiO2@Au core-shell nanostructures. In this method, chloroauric acid was reduced with trisodium citrate in the presence of amine-functionalized silica or titania submicroparticles. Core-shells obtained in this way were compared to structures fabricated by mixing of Turkevich AuNPs with am...

Double-stranded nucleic acids from a strain of Penicillium chrysogenum containing RNA viruses were isolated by agarose-gel filtration, and separated into DNA and double-stranded RNA fractions by agarose-gel chromatography in 2.5m-NaCl. The DNA fraction contained less than 1% alkali-labile polynucleotides, and sedimented homogeneously at 8-10S in alkaline sucrose gradients. In CsCl gradients it ...

Infection of central venous catheters used for haemodialysis remains an important cause of morbidity and mortality [1]. Patency of the catheters can be maintained between dialyses by a heparin lock, but this has no antibacterial activity. Sodium citrate, especially at higher concentrations, is an anticoagulant with intrinsic antibacterial activity [2]. However, citrate inadvertently entering th...

It is generally acknowledged that calcium lactate (ca-lactate) fortification of soymilk to achieve the equivalent level in cow’s milk (1.2 mg/g) causes instability soymilk. In order produce acceptable calcium-enriched with great stability, three different kinds chelating agents were added, namely tripotassium citrate (TPC), trisodium (TSC), and sodium hexametaphosphate (SHMP). this study, addit...

The hull plates of the ship made mild steel (MS) are always in contact with seawater aggressive ions such as chloride present seawater.The corrosion resistance has been investigated by polarization study. Sandalwood oil extract containing 5 g each Cardamom (disambiguation), Clove Nutmeg, India Sambrani (loban), Chrysopogon zizanioides, commonly known vetiver and Camphor was used inhibitor along...

The paper presents a coaxial-like sensor operating in the 20 Hz-2 MHz frequency range used to determine the electrical properties of selected liquids of low electrical conductivity. Examined materials included low-concentrated aqueous solutions of potassium chloride, sodium chloride and trisodium citrate, which are common food additives. Impedance spectra of the measurement cell filled with par...

Cu nanoparticles dispersed in water were prepared by the reduction of Cu originated from the copper salt solution. The stability of the Cu nanoparticles in dispersion was monitored through the analysis of the absorbance spectra at different stages during the process of synthesis. The stability of the Cu nanoparticles dispersed in aqueous medium was investigated after different time intervals. C...
