100 bilayers 2-nitro-5-(N-methyl-N-octadecyl)aminobenzoic acid (NMOB) and cadmium arachidate (CdA) alternated Langmuir–Blodgett (LB) film was fabricated. The thickness of NMOB monolayer is 2.85 nm measured by small angle X-ray diffraction. It shows that NMOB molecule stands vertically in the al...
Biodiesel is a renewable, alternative diesel fuel derived from various oils or fats through transesterification. Biodiesel usually consists of alkyl esters of the parent oil. Palm-oil methyl ester (PME) is a prominent biodiesel in Southeast Asian countries such as Malaysia and Indonesia, which h...
True molecular resolution with the atomic force microscope (AFM) has been achieved, on Langmuir–Blodgett multilayers, using films of cadmium arachidate on mica. The images were obtained with 12 μm scanner head and commercially purchased cantilevers with spring constant k=0.06 N m−1 under ambie...
Fuel unsaturation has been widely cited as a reason for the increased nitric oxide emissions from compression ignition engines when fueled with methyl esters (biodiesels) and their blends with petroleum counterparts. In an earlier study, a parameter called degree of unsaturation (DOU) was establ...
Langmuir isotherms of a trivalent indium arachidate monolayer and its Langmuir–Blodgett deposition are reported. Transferred multilayers were characterised by Fourier transform infrared and X-ray diffraction measurements. Results indicate that the film consists mainly of arachidate salt in a la...
A combination of grazing incidence X-ray reflection/diffraction (GIXR/GIXD) and atomic force microscopy have been used to study the 3D structure in cadmium arachidate (CdA) and single phase zinc arachidate (ZnA) LB multilayers. The CdA multilayers have an ideal close packed herringbone structure...
Nineteen monolayered Cd arachidate films were deposited on float glass substrate coated with Si and Ni over-layers. Two layers have been chosen with very different surface free energies. Melting behavior of films were studied using variable temperature X-ray specular reflectivity and Fourier tra...
The structure of calcium arachidate Langmuir-Blodgett monolayers that were prepared at different pH in the subphase, were studied using vibrational sum frequency spectroscopy with a focus on testing their stability against melting upon heating. The pH controls the degree of deprotonation of the ...
The Langmuir—Blodgett technique has been used for the preparation of magnetic multilayer films of manganese arachidate either as a pure component or in mixture with the diamagnetic methyl arachidate. The mutual surface miscibility of both compounds was verified from the spreading isotherms of t...
The association of fatty acid composition with insulin resistance and type 2 diabetes has been reported in Western populations, but there is limited evidence of this association among the Japanese, whose populace consume large amounts of fish. To test the hypothesis that high palmitic, palmitole...
This paper presented experimental results to evaluate the optimization of production parameters through response surface methodology. These parameters significantly affected the yield of cottonseed oil methyl ester (COME). The input variables for the production of methyl ester from cottonseed oi...
While biodiesel production is on the rise, so too is the production of the low-value product, glycerol. Interesterification is an alternative reaction that produces fatty acid methyl esters (FAME) and avoids the production of glycerol. In this work, ferric sulfate is used as a potential heteroge...
Palmitoleic acid is found in certain dairy products and has broad applications in medicine and cosmetics. We tried to find a suitable producer of this acid among traditional biotechnological yeast species (Kluyveromyces polysporus, Torulaspora delbrueckii, Saccharomyces cerevisiae) characterized...
This study aimed to evaluate the potential of six oleaginous eustigmatophytes for use as biorefinery feedstock for the co-production of palmitoleic acid (PA) and biodiesel under different initial nitrogen concentrations (INCs). Six eustigmatophytes were studied, the nitrogen deficiency strategy ...
Non-canonical amino acids add extraordinary chemistries to proteins when they gain access to translation. In yeast, they can be incorporated into proteins by replacing a canonical amino acid or in a site-specific manner in response to an amber stop codon. The first approach simply exploits the n...
Treatment of nonanamides C8H17C(O)NR2 (R = H or Et) with superelectrophilic complex CBr4·2AlBr3 under CO atmosphere followed by quenching with nucleophiles NuH cleanly gives 7-methyl-7-(Nu-carbonyl)octanamide bifunctional derivatives.
In continuation to our prior investigational studies on the interactions between binary mixtures of alkoxy alkanols and alcohols, here, we report the thermo-physical properties and spectra analysis of 2-(2-butoxyethoxy) ethanol with CH3(CH2)3OC2H4O(CH2)2OH, viz., 1-hexanol CH3(CH2)5OH, 1-octanol...
The synthesis and characterization of a new series of catanionic multivalent analogs of GalCer is described. These systems are based on phosphonic acid terminated dendrimers and N-hexadecylamino lactitol moieties. Despite important structural differences that affect the dendrimers’ outer-shell,...
Herein, conditions for the fast and effective reduction of aromatic nitro groups bound to hydrophobic polystyrene-based Wang and Ring resins utilizing sodium dithionite in dichloromethane–water under PTC conditions are reported. Tetrabutylammonium hydrogen sulfate (TBAHS) was found to be an eff...
A surfactant-mediated solid phase extraction procedure is applied for the preconcentration of benzalkonium (BA) chloride from a river water sample. Dodecyl sulfate is attached to a strong anion exchange resin and aqueous samples are passed through a column containing this surfactant-resin materi...
