Hevea brassiliensis (rubber wood) was esterified with palmitoyl chloride, prepared from the reaction of palmitic acid with thionyl chloride. The weight gain of the wood increased with increasing reaction time and temperature, the esterified wood were evaluated for their photostability and dimens...

Neoplastic cells display altered biosynthetic and bioenergetic machinery to support cell survival. Therefore, cancer cells optimally utilize all available fuel resources to pump their highly upregulated metabolic pathways. While glucose is the main carbon source, transformed cells also utilize o...

The interaction between sodium dodecyl sulfate (SDS) and a blend of polyaniline (PANi) and cellulose acetate (CA) is discussed. This interaction is shown to lead to a red shift of the maximum absorption wavelength in the visible spectrum. The behaviour, which is similar to what is seen on proton...

An original and green flotation method for separation of small amount of boron from aqueous solution has been developed using sodium dodecyl benzene sulfonate as the surfactant which is no-poisonous and economical for removing boron from aqueous solution. The removal of boron from brine and othe...

A residual solvent study in poly(vinyl alcohol)-water based system has been carried out. The effect of anionic surfactant sodium dodecyl sulphate on the drying behavior of coatings was investigated. Attempts were made to optimize the surfactant loading in order to minimize the residual solvent a...

The effect of addition of sodium dodecyl sulfate (SDS) anionic surfactant on the characteristics and performance (i.e. flux and rejection) of cellulose acetate (CA) nanofiltration membrane was investigated at this study. Nitrophenols (p-nitrophenol (PNP) and 3,5-dinitrosalicylic acid (DNSA)) wer...

The preparation of polyaniline (PANi)–cellulose acetate (CA) blends by casting films from a suspension, is reported. Two membranes were prepared from different solvents, one with a homogeneous and the other a heterogeneous dispersion of PANi in CA matrices. The membranes were characterized by X...

In the process of dissolution method development for Merck proprietary compound A, a basic analyte, abnormal chromatographic behavior involving peak splitting and retention time shifting in the presence of sodium dodecyl sulfate (SDS) in the sample solution was observed. A mechanistic study was ...

Complex coacervation of whey protein (WP) with acacia gum (AG) was carried out in water with the presence of dodecyl acetate (DA), a component of insect sex pheromones, in order to obtain microcapsules with DA as the core material and WP–AG coacervate as the wall materials. Through variations i...

Liquid-liquid-powder extraction (LLPE) is the process of transferring fine solid particles from one liquid phase to another immiscible liquid in contact across the liquid-liquid boundary using a surface-active agent as a collector. LLPE has been applied to semiconductor fine solid waste to extra...

The subchronic toxicity following oral administration of Dodine was studied in male and female rats. Animals received 5, 10, or 20 mg/kg of the product suspended in carboxymethyl cellulose daily for 90 days. Control animals received 10 ml/kg of the vehicle. No clinical signs of toxicity were obs...

Dodine is an agricultural fungicide used to combat certain diseases of fruit trees. Structurally, it is a cationic surface-active compound, and, in single or repeated doses, exhibits essentially the toxicologic properties that are characteristic of this class of compounds. Its most conspicuous t...

The effect of subchronic administration of the pesticide dodine (n-dodecylguanidine acetate) on rat small intestine was studied after 90 days of oral administration at a dose of 20 mg/kg/day. No alteration was observed in the body weight evolution or food intake during this period. The protein c...

In a work published in this journal by J.P.S. Cabral and A.R.W. Smith [J. Colloid Interface Sci. 149 (1992) 27], it is reported that the 1-dodecylguanidinium acetate (dodine) exhibits first CMC at 20–30 μM and second CMC at 110–120 μM in aqueous solution at 22.5 °C. Such low CMCs are unusua...

Critical micelle concentrations (CMCs) of dodecylguanidine monoacetate (dodine) were determined at 22.5°C by UV spectroscopy and from measurements of dye complexation, surface tension, and capillary rise. Over the range 5–260 μM dodine, two discontinuities were found in the relationship betwe...

Acid functionalization of multi-walled carbon nanotubes (F-MWCNTs) using a mixture of HNO3 and H2SO4 (1:3, v:v) was used as support materials for the adsorption of Candida rugosa lipase (CRL) as nanoconjugates (CRL-MWCNTs) for producing methyl oleate. To evaluate the competency of the CRL-MWCNTs...

Supercritical extraction is the utilization of a fluid operating above its critical temperature and pressure as a solvent to remove certain compounds from a mixture. It is an innovative technology for which there are relatively few models describing the interaction between the phases. In particu...

A new kind of silicon-based biological lubricating base oil with good viscosity-temperature behavior, viscosity index, thermostability, oxidation stability and wear resistance performance was synthesized as a derivative of methyl oleate. Trimethylsilylation reaction was introduced to further imp...

The effect of the support on the catalytic performance of sulfided NiMo in the hydrodeoxygenation of methyl oleate as a model compound for triglyceride upgrading to green diesel was investigated. NiMo sulfides were prepared by impregnation and sulfidation on activated carbon, silica, γ-alumina ...
