The viscoelastic relaxations of four copolymers of ethylene and 1-octadecene, with different comonomer contents, synthesized with a metallocene catalyst, have been analysed and compared to those of the corresponding polyethylene homopolymer. Similar to other ethylene copolymers, the temperature ...

The reactions of a terminal alkene (1-octadecene) and a polymethyl phenol (2,3,6-trimethylphenol) on activated carbon have been investigated in closed system pyrolysis experiments in the temperature range 170–340 °C. The reaction products of 1-octadecene included methane, isomeric octadecenes,...

In this paper, we report the complete 13C NMR characterization of a set of ethylene–propylene–1-octadecene terpolymers obtained with the metallocenic system rac-ethylene bis-indenyl zirconium dichloride, using different comonomer ratios. A detailed study of 13C NMR chemical shifts, triad seque...

Tailor-made isotactic polypropylene (iPP) and propylene/1-octadecene (CiPP-OD) copolymers synthesized via a metallocene catalyst were used for membrane preparation by the thermally induced phase separation (TIPS) process. Although the resulting morphology of the membranes and porosity were found...

Development of protocols for transferring of hydrophobic quantum dots (QDs) into aqueous solution is of special importance for their biomedical applications. Particularly, hydrophilization of Ag2S without quenching of photoluminescence is a great challenge. Application of standard protocol for a...

Ethylene homopolymer and ethylene-co-1-octadecene copolymers with 0.063 mol/L (LLDPE-1) and 0.38 mol/L (LLDPE-2) were synthesized by a metallocenic catalyst in the presence of titanium dioxide (TiO2) nanoparticles (∼10 nm), producing “in situ” composites. The TiO2 nanoparticles synthesized by...

This paper reports the polymerization of 1-octadecene catalyzed by a series of α-diimine Ni(II) complex, with methyl ligand backbone and different substituents in the ortho and para aryl positions, in combination with Et2AlCl. We obtained semicrystalline ethylene–propylene–1-octadecene terpol...

Overconsumption of erucic acid has been shown to cause heart damage in animals. The aim of this study is to evaluate the binding behaviour between erucic acid and bovine serum albumin using multi-spectroscopic methods and a molecular docking technique under physiological conditions. We find that...

BackgroundPPAR-δ is a transcription factor which has crucial roles in stimulating oligodendroglial differentiation and myelination and its activation was also shown to differentiate malignant C6 glioma cells into oligodendrocytes.

Erucic acid (EA) is one of the key fatty acids usually found in canola oil, mustard oil and rapeseed oil. Consumption of EA in primates was found to cause myocardial lipidosis and cardiac steatosis. To have an insight of the effect of EA in humans, we performed in vitro interaction studies of EA...

Pennycress (Thlaspi arvense L.) is a winter annual that has a wide geographic distribution and a growth habit that makes it suitable for an off-season rotation between corn and soybeans in much of the Midwestern United States. Pennycress seed contains 36% oil with 36.6% erucic acid content There...

Erucic acid is a monounsaturated omega-9 fatty acid isolated from the seed of Raphanus sativus L. that is known to normalize the accumulation of very long chain fatty acids in the brains of patients suffering from X-linked adrenoleukodystrophy. Here, we investigated whether erucic acid enhanced ...

Erucic acid is a typical constituent of mustard or rape. Foodstuff with a high content of erucic acid is considered undesirable for human consumption because it has been linked to myocardial lipidosis and heart lesions in laboratory rats. As a result, several countries have restricted its presen...

Coal tar pitch (CTP) was modified using erucic acid, CH3(CH2)7CH=CH(CH2)11COOH, and the rheological and surface properties of the modified CTP were evaluated. The effect of erucic acid was investigated using a rotational viscometer as well as by drop and weight tests. The modified CTPs were char...

The transcription factor, PPARδ is involved in suppressing inflammation, stimulating oligodendroglial biogenesis and myelination. Furthermore, activation of PPARδ directly protects mitochondria against noxious stimuli and stimulates biogenesis of new mitochondria. PPARδ activation directly in...

This study presents a novel method to determine erucic acid in canola oil samples by using Raman spectroscopy and chemometric analysis. The oil mixtures were prepared at various concentrations of erucic acid ranging from 0% to 33.56% (w/w) through binary combinations of different oils. In order ...

Energies of combustion at 298.15 K were measured for 1-bromododecane and 1-bromohexadecane, and enthalpies of formation were derived for the compounds in the liquid and gaseous states: ΔHfo(l)/kJ mol−1ΔHfo(g)/kJ mol−11-bromododecane−344.7±2.6−269.9±2.61-bromohexadecane−444.5±2.8−350.1±3.2

Films of 1-heptadecanoic acid and 1-bromohexadecane have been studied by measuring the surface pressure-area (π-A) isotherms at 15°C during compression. Pure bromohexadecane on a pure water surface does not form an insoluble monolayer. The configuration of the mixed isotherms changes with comp...

Nitro-fatty acids modulate inflammatory and metabolic stress responses, thus displaying potential as new drug candidates. Herein, we evaluate the redox behavior of nitro-oleic acid (NO2-OA) and its ability to bind to the fatty acid transporter human serum albumin (HSA). The nitro group of NO2-OA...

The immobilization of Candida rugosa lipase (CRL) onto biochar was studied in a series of batch experiments. CRL sorption behavior was evaluated as a function of pH, enzyme concentration, temperature and ionic strength. As the immobilized lipase was used for the catalytic esterification of oleic...
