dodecane/dichloromethane

In the so-called milking process of Dunaliella salina carotenoids are extracted and simultaneously produced by the culture, whilst the biomass concentration remains constant. Different theories exist about the extraction mechanisms although none have been proven yet. In this research, direct contact

Changes in the (31)P NMR chemical shift of tri-n-butylphosphine oxide have been measured as function of solvent composition in a number of binary solvent mixtures. The data were analysed using a model that separates the contributions of specific H-bond interactions with the first solvation shell and

Femtosecond fluorescence upconversion and transient absorption experiments have been performed to monitor the photoinduced electronic, geometry, and solvent relaxation dynamics of 1,8-bis(dimethylamino)naphthalene dissolved in methylcyclohexane or n-hexane, n-dodecane, dichloromethane, and

A method has been developed for the simultaneous determination of benzene, toluene, xylene, styrene, decane, diethylbenzene, undecane, divinylbenzene, dodecane and naphthalene residues in macroporous adsorption resins (MARs). The organic residues were extracted from resin samples by ultrasonic

Inverse gas chromatography, IGC, was applied to characterize conducting polypyrrole chloride (PPyCl) using twenty three solvents. IGC is able to reveal the change in the morphology, the strength of solvent-PPyCl interactions, thermodynamics parameters (χ12, Ω1(∞)), solvent and polymer solubility

A dry fermented sausage (chorizo de Pamplona) was elaborated with the simultaneous addition of a lipase (Novozym 677BG) and a protease (Flavourzyme) and ripened during 21 days, in contrast to the control without enzymes and ripened during 35 days. Faster and more intense lipolytic and proteolytic

"Pickering-type" emulsions were prepared using polydopamine (PDA) particles as a particulate emulsifier and n-dodecane, methyl myristate, toluene or dichloromethane as an oil phase. All the emulsions prepared were oil-in-water type and an increase of PDA particle concentration

An improved analytical method was developed and validated for the determination of the monosaccharide anhydrides levoglucosan, mannosan, and galactosan in atmospheric aerosol samples. The method uses an external recovery standard, extraction in dichloromethane, trimethylsilylation, addition of an

The discotic molecule 4-chloro-2,6-bis(octadecylamino)-pyrimidine-5-carbaldehyde, displays gelation behavior in dodecane, heptane, chloroform, and dichloromethane. The aggregation behavior of this material was studied by dynamic light scattering, differential scanning calorimetry, scanning electron

Hydrosilylation of polymethylhydrosiloxane (active hydrogen content was 0.05%) and reactions with allylbromide (or undecenyl bromide), sodium azide and [60] fullerene in their given orders is described. Two kinds of fullerene-containing polysiloxanes were obtained [polymer(3)]. Their [60] fullerene

In the present study, the chemical composition of the essential oil and methanol (MeOH) extract of aerials of E. azerbaijanica were identified. Furthermore, the free radical scavenging properties of the volatile oil as well as the MeOH extract of the plant were assessed. The essential oil of the

OBJECTIVE To determine the contributions of main chemical compositions of extracts of Eucalyptus camaldulensis represented by GC/MS elute peaks to the molluscicidal activities, and explore a shortcut of looking for the effective components from natural products. METHODS E. camaldulensis leaves were
