Adsorption from binary solutions of polar n-decyl derivatives and heptane onto alumina
… adsorption of n-decanol, n-decylamine, n-decanoic acid, and ethyl octanoate from binary solutions with heptane onto alumina was studied. The net surface excess isotherms were measured and resolved into component isotherms. The heat of immersion of the alumina in n-decanol, ethyl octanoate, …

Fatty Acid Degradation in Escherichia Coli and Salmonella Enterica Serovar Typhimurium
Wild type strains of S. enterica grow on decanoic acid whereas wild type E. coli strains cannot. Mutant strains (fadR) of both organisms are readily isolated in which the genes (fad) of fatty acid degradation are expressed constitutively. The S. enterica fadR strains grow more rapidly than the wild …

X -Ray Diffraction Rotational Microrheology
… Alumina tracer particles suspended in liquid decanoic acid show subdiffusive behavior transitioning towards diffusive behavior with a crossover time of 20-50 sec. The same system shows superdiffusive motion in the solid state below the glass transition temperature of the decanoic acid.

Experimentation and application of directional solvent extraction for desalination of seawater and shale gas 'frac' flowback water
… is that when certain organic oils such as decanoic acid are heated, they dissolve water without dissolving some other water soluble substances such as sodium chloride which can later be removed; upon cooling the absorbed water precipitates and is collected. This technique was tested to …

Enzymatic acylation of starch
… is employed for starch esters with fatty acids of medium chain length and can be suitably modified to accommodate other chain lengths. Lipase catalysed synthesis of starch esters with decanoic acid was performed in concentrated aqueous systems, where the starch is gelatinised prior to …

Electrostatic Atomization Of Antimicrobial Treatments On Ground Beef Processing, Instrumental Color, Sensory Color, Taste and Aroma Characteristics
… Antimicrobial treatments included: fumaric acid, malic acid, octanoic acid, decanoic acid, sodium propionate, propionic acid solution, potassium lactate/diacetate blend, sodium benzoate, hexanoic acid, pyruvic acid, levulinic acid, lactic acid/ citric acid blend, sodium diacetate, lemon …

Liquid collection efficiencies after supercritical fluid extraction
… naphthalene, <i>n</i>-decanoic acid, 2-naphthol, and <i>n</i>-tetracosane was spiked onto sand and extracted with supercritical carbon dioxide to evaluate the collection efficiency of various solvents and solvent mixtures. Nine single collection solvents and four mixed …

A preliminary analysis of the lipid contents of a biofilm from a Yellowstone hydrothermal pool
… methanolysis allowed for the identification of decanoic acid methyl ester, a fatty acid methyl ester. From the column chromatography, only the saturated hydrocarbon fraction yielded interesting compounds; these were a series of n-alkanes (n-C₁₇, n-C₂₀, and n-C₂₃ - n-C₃₁), two branched alkanes …

Solvent extraction of cobalt and nickel carboxylates
… by a variety of systems containing carboxylic acids in the presence of 1,2-diaminoethanes was investigated in order to determine the extent to which these complexes extract into different solvents. The aromatic carboxylic acids studied were benzoic, p-toluic, phenylacetic, cinnamic, anthranilic …

Estudio analítico de compuestos volátiles en vino: caracterización quimiométrica de distintas denominaciones de origen
… (SD), phenyl ethyl acetate (AFE), hexanoic acid (AH), geraniol (G), phenyl ethyl alcohol (2FE), octanoic acid (AO), decanoic acid (AD). This method was allowed to determine the VOCs identified in the wine samples providing good sensitivity and reproducibility. These compounds selected were …

Temporal change in the Namibian Ju|’hoansi intestinal microbiome
… IM, and the levels of the IM volatile fatty acids. In order to do so, faecal samples were collected and subsequently sequenced from a total cohort of 40 participants taken 2 years apart in 2019 and 2021. Based on our study, we were able to identify changes in the composition of microbial …

Directional solvent extraction desalination
… solvents used here include soybean oil, hexanoic acid, decanoic acid, and octanoic acid with the last two observed to be the most effective. These fatty acids exhibit the required characteristics by having a hydrophilic carboxylic acid end which bonds to water molecules but the hydrophobic chain …

Investigation of Liquid Trapping Following Supercritical Fluid Extraction
… did. The occurrence of a methylation reaction of decanoic acid during the SFE and collection processes, using a methanol modified fluid or collection solvent was investigated. The majority of the reaction occurred during the collection process and the degree of methylation was found to be …

Synthetic sensing systems in Saccharomyces cerevisiae
… yeast to detect medium chain length fatty acids, alcohols and aldehydes for the first time. Functionally expressing heterologous olfactory receptors in yeast is a challenging task because no definitive method exists on how to express such receptors on the yeast cell surface and couple them …

The role of the free fatty acid, lauric acid, in appetite regulation and its potential as an appetite-suppressant.
… that the digestion of fat into free fatty acids is required for these effects to occur. Furthermore, the effects of fatty acids are dependent on their chain length. The research presented in this thesis relates to the effects of fatty acids, particularly lauric acid, on the regulation of …
