Arguelles, Eldrin DLR. published the artcileLipid accumulation and profiling in microalgae Chlorolobion sp. (BIOTECH 4031) and Chlorella sp. (BIOTECH 4026) during nitrogen starvation for biodiesel production, HPLC of Formula: 110-42-9, the main research area is Chlorolobion Chlorella lipid accumulation nitrogen starvation biodiesel.

When the amount of nitrate was limited, the mean oil contents of Chlorolobion sp. and Chlorella sp. were 31.61 and 28.77% with lipid productivity of 227.84 and 151.14 mg L-1 day-1, resp. Nitrogen starvation caused an increase in the lipid yield and a decrease in biomass production of the two microalgae. The FAME profile of the obtained algal biodiesel shows a high concentration of saturated fatty acid (SAFA) and monounsaturated fatty acid (MUFA) Me esters which are desirable for biodiesel production The fuel properties of biodiesel from the two microalgae were predicted based on the mol. properties of fatty acid Me esters using empirical equations showing that the biodiesel properties of the two microalgae satisfied the set specifications of biodiesel standards EN 14214 (European) and ASTM D6751 (American). The quality properties of biodiesel obtained for Chlorolobion sp. were low d. (0.89 g cm-3), low kinematic viscosity (2.79 mm2 s-1), cetane number (65.17), and oxidation stability (8.93 h). On the other hand, Chlorella sp. has low d. (0.88 g cm-3), low kinematic viscosity (2.78 mm2 s-1), good cetane number (68.79), and oxidation stability (10.44 h). Hence, Chlorolobion sp. (BIOTECH 4031) and Chlorella sp. (BIOTECH 4026) have potential as raw material for production of biodiesel with superior fuel quality.

A comparative anal. of free amino acid and volatile organic compounds profile of dawadawa produced from the seeds Parkia biglobosa, Glycine max and Hibiscus sabdariffa was evaluated. The free amino acid profile were analyzed using amino acid analyzer while the volatile organic compound profile were analyzed using Gas -Chromatog.-Mass Spectrometry (GC-MS). Difference was observed in the amino acid profile of the dawadawa with laboratory produced dawadawa recording an increased in the essential amino acid lysine, valine, methionine and leucine while tyrosine been the only non-essential amino acid that slight increased. Aspartic and glutamic acids seems to be the major amino acids in locally produced dawadawa with a value of 9.00 and 17.26 g/100 g protein. Fermentation increased the bioavailability of aspartic acid (9.00 to 9.31 g/100 g protein) while the glutamic acid decreased from 17.26 to 14.38 g/100 g protein after fermentation under laboratory conditions. The locally and laboratory produced dawadawa from G. max, the laboratory produced dawadawa showed increased in the six essential amino acid. The essential amino acid leucine and non-essential amino acids aspartic and glutamic acid are identified as the major amino acids in locally produced dawadawa from locust bean. The locally produced dawadawa from H. sabdariffa had the highest amino acid for lysine, valine glutamic acid and proline while threonine was the same in both local and laboratory produced. The locally and laboratory fermented seeds of P. biglobosa showed several volatile compounds in both dawadawa with locally produced dawadawa having 21 volatile organic compounds while dawadawa produced in the laboratory had 24 volatile organic compounds The G. max produced dawadawa had 6 esters, 5 amides, 4 acids, 3 alcs., 2 hydrocarbons and one heterocyclic compound The volatile organic flavor compounds detected in dawadawa produced from H. sabdariffa seeds include 2 acids class flavor volatile, 1 alcs., 2 aldehydes, 2 ketones, 2 amides, 4 carbonyl, 8 esters, 8 hydrocarbons and 1 phenol.

Yang, Xiaoqiu published the artcileNon-targeted screening and analysis of volatile organic compounds in drinking water by DLLME with GC-MS, Application In Synthesis of 110-42-9, the main research area is volatile organic compound drinking water analysis DLLME GC MS; Dispersive liquid-liquid microextraction; Drinking water; In silico toxicity prediction; Non-targeted analysis; Volatile organic compound.

Volatile organic compounds (VOCs) in drinking water may potentially be hazardous. We developed a novel non-targeted anal. method of VOCs in drinking water that uses dispersive liquid-liquid microextraction coupled with gas chromatog.-mass spectrometry. Anal. parameters were selected from range-finding tests on the peak number and average area of the extracted compounds The optimized method was applied to analyze VOCs in tap water samples collected from Wuhan City, China. Twenty-seven compounds with high match degrees and a high prevalence were selected for quantification and evaluation. We used structure-activity relationships to predict the carcinogenicity of these compounds Although most of the compounds were non-toxic, compounds such as di-Bu phthalate and diacetone alc. should be investigated further. Untargeted anal. of the tap water samples identified 75-200 VOCs, including 67 highly prevalent compounds Industrial and pharmaceutical chems. accounted for approx. 70% of the VOCs in the samples. This method of non-targeted anal. and in silico toxicity prediction is simple and economic, and could be used in screening VOCs in drinking water.

Shrestha, Shyam Sharan published the artcilePhytochemical Investigations and In Vitro Bioactivity Screening on Melia azedarach L. Leaves Extract from Nepal, Synthetic Route of 110-42-9, the main research area is Melia leaf phytochem compound bioactivity; Melia azedarach; enzyme inhibitory assays; phytosterols; polyphenols; traditional Nepalese medicine.

Melia azedarach is a common tree used in the traditional medicine of Nepal. In this work, leaves were considered as source of bioactive constituents and composition of methanol extract was evaluated and compared with starting plant material. Flavonoid glycosides and limonoids were identified and quantified by HPLC-DAD-MSn approaches in dried leaves and methanolic extract, while HPLC-APCI-MSn and GC/MS anal. were used to study phytosterol and lipid compositions β-Sitosterol and rutin were the most abundant constituents. HPLC-APCI-MSn and HPLC-DAD-MSn anal. revealed high levels of phytosterols and flavonoids in methanolic extract accounting 9.6 and 7.5% on the dried weight, resp. On the other hand, HPLC/MSn data revealed that limonoid constituents were in minor amount in the extract <0.1%, compared with leaves (0.7%) indicating that degradation occurred during extraction or concentration procedures. The methanol extract was subjected to different bioassays, and antioxidant activity was evaluated. Limited inhibitory activity on acetyl and butyryl cholinesterase, as well as on amylase were detected. Moreover, tyrosinase inhibition was significant resulting in 131.57±0.51 mg kojic acid equivalent/g of dried methanol extract, suggesting possible use of this M. azedarach extract in skin hyperpigmentation conditions. Moderate cytotoxic activity, with IC50 of 26.4μg/mL was observed against human ovarian cancer cell lines (2008 cells). Our findings indicate that the Nepalese M. azedarach leaves can be considered as valuable starting material for the extraction of phenolics and phytosterols, yielding extracts with possible cosmetic and pharmaceutical applications.

Taghizadehfard, Mahsa published the artcileViscosity modeling of fatty acid esters and biodiesels based on friction theory and perturbed hard-dimer-chain equation of state, Computed Properties of 110-42-9, the main research area is fatty acid ester biodiesel friction theory viscosity PHDC EOS.

This work deals with the modeling of dynamic viscosities of several fatty acid esters (FAEs) and biodiesels based on the friction theory (FT) along with a perturbed hard-dimer-chain equation of state (PHDC EOS). The model used three mol. parameters (ε, σ, m) and liquid d. as well, all of which were estimated from the PHDC EOS. The PHDC EOS could predict the d. and isothermal compressibility coefficients in 278.15-393.15 K range and pressures up to 210 MPa with the average absolute relative deviations (AARDs) of 0.52% and 4.77%, resp. Then, the proposed FT-based model has been employed for predicting the dynamic viscosities of several FAEs and biodiesels in 293.15-393.15 K and pressures up to 200 MPa. The model predicted 892 exptl. data points for dynamic viscosities of 10 FAEs and 3 biodiesels with the AARD of 1.70%. Further, the degree of accuracy of proposed model has also been compared with some semi-theor. and empirical approaches. Our comparison results revealed the superiority of the proposed model against the literature approaches.

Rani, Manju published the artcileSolid-liquid equilibrium and kinematic viscosity of binary mixture of fatty acid alkyl esters, Quality Control of 110-42-9, the main research area is solid liquid equilibrium kinematic viscosity binary mixture fatty acid.

The separation and recovery of fatty acid alkyl esters (FAAE) is of great significance for various industries. Crystallization is a well-suited separation process for fatty acid mixtures which may be evolved by the understanding of solid-liquid equilibrium (SLE). The SLE and kinematic viscosity (v) at (T=298.15-318.15 K) and (P=0.1 mPa) for binary mixture of FAAE: Me decanoate (1)+ethyl decanoate or Me dodecanoate or Me tetradecanoate (2) has been studied. The deviation in kinematic viscosity (Δv) data was derived using exptl. v data. The measured SLE exhibit general single eutectic point like other organic mixtures The SLE data fit well with universal quasi-chem. (UNIQUAC) equation. The v values were interrelated using different equations recommended by Heric-Brewer, Krishnan-Ladda, and Lulian et al. Theor. estimated values using these empirical equations are in accordance with the exptl. values with percentage standard deviation less than 0.35. The v were also analyzed by means of the McAllister equation. The Δv data were also fitted with the Redlich-Kister polynomial equation. All three binary mixtures showed neg. Δv values.

Owen, Rhodri N. published the artcileTowards a universal ion source: Glow Flow mass spectrometry, Application In Synthesis of 110-42-9, the main research area is ion source glow flow mass spectrometry.

A helium-microplasma ion source (Glow Flow) has been developed and characterised. It is engineered to be a simple design, of low-cost and can be readily retrofitted to most modern mass spectrometers. Initial assessment of its performance has shown it to be robust, reproducible and of high sensitivity. Glow Flow provides broad non-specific detection of samples from polar through to non-polar chemistries making it of wide utility. A study of persistent organic pollutants, polyaromatic hydrocarbons, low average-mol.-mass polymers (polyethyleneimine, polyethylene glycol, and polypropylene glycol) and a complex mixture of fatty-acid Me esters by direct sample introduction using a nebulised heated nitrogen flow was conducted. The ability to make quant. measurement was investigated using Me stearate and a linear calibration plot gave a R2 = 0.999 and limit-of-detection of �00 fmol. This design is extremely stable, in operation. Typical ions commonly observed are intense protonated mol. ions, radical mol. ions, hydride abstracted ions, and oxygen adduct ions. At present this system is valuable to apply to small mol. anal. (m/z < 1000), and is easily interfaced to gas and liquid chromatog., and likely to be useful for imaging.

Mousavi, Nayereh Sadat published the artcilePredicting the surface tension of mixtures of fatty acid ethyl esters and biodiesel fuels using UNIFAC activity coefficients, HPLC of Formula: 110-42-9, the main research area is surface tension mixture FAME biodiesel fuel UNIFAC.

This work presents the use of a formal thermodn. model together with UNIFAC activity coefficients model, without any further adjustable parameter, to predict the surface tension of biodiesel fuels based on the equality of chem. potentials between the vapor-liquid interface and liquid bulk. The biodiesel samples included in this work were reported previously in the open literature. They were produced from vegetable oils such as: canola, coconut, corn, cottonseed, hazelnut, lard, palm, peanut, rapeseed, safflower, soybean, sunflower, and Walnut. Surface tension values for 18 samples of binary, ternary and quaternary mixtures of fatty acid Et esters (FAEEs) at T = 298.15 were predicted with an average absolute relative deviation (AARD) = 1.39%. Surface tension values for 31 biodiesel samples composed by fatty acid Me esters (FAMEs) were also predicted at temperatures from 303.15 K to 353.15 K. The AARD value obtained for the 78 exptl. points of biodiesel samples was 1.86% which shows a very good agreement with exptl. measurements. In the UNIFAC method, predictions of surface tension values for the mixtures are based on the knowledge of the values of the surface tension for the pure components; these values were obtained from different sources. Also, two simple mixing rules on mass and mole fraction basis were used to predict the surface tension of biodiesel fuels. The AARD value obtained from the comparison between exptl. and calculated values were: 2.77% and 2.91% for mixing rules on mass and mole fractions, resp.
