Uribe-Echeverria, Teresa published the artcileAcute toxicity of bioplastic leachates to Paracentrotus lividus sea urchin larvae, Formula: C23H46O2, the main research area is Paracentrotus lividus acute toxicity bioplastic leachates; Additives; Bioplastic; Ecotoxicology; Larval bioassay; Microplastic; Paracentrotus lividus; Polyhydroxybutyrate; Polylactic acid.

In an attempt to ensure that bioplastics, progressively replacing petrochem.-derived plastics, do not release any harmful compound to the environment, the study assessed the toxic effects of three innovative bioplastic products: polyhydroxybutyrate resin (PHB), polylactic acid cups (PLA) and a polylactic acid/polyhydroxyalkanoate 3D printing filament (PLA/PHA), together with a synthetic polyvinyl chloride (PVC) toy in Paracentrotus lividus sea urchin larvae. PVC toy was the most toxic material, likely due to the added plasticizers; remarkably, even if PHB is conceived as a nontoxic polymer, it showed a slight toxicity and Gas Chromatog.-Mass Spectometry anal. (GC-MS) revealed the presence of a wide range of additives. Conversely, PLA cups and PLA/PHA filament were innocuous for the larvae, a pos. outcome for these renewable solutions Proven that additives are also used in some bioplastic formulations, they should be carefully addressed to ensure that they are as safe as regarded.

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, SDS of cas: 929-77-1, 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.

Aitbelale, Rachid published the artcileEffects of 2-Butanol Addition on Waste Cooking Oil Biodiesel Density: An Updated Experimental Measurement and Thermodynamic Modeling Study, Application In Synthesis of 929-77-1, the main research area is butanol cooking oil biodiesel mixture density thermodn modeling EOS.

Biodiesels will become the most popular alternative energy resource to fossil diesels; they can be used alone or blended with an oxygenated additive in any proportion. The properties of biodiesels strongly depend on the type of the fatty acid Me esters (FAME) that compose them. The main objective of the present work is to study the influence of 2-butanol addition on the waste cooking oil biodiesel (WCOB), for this fact, the new exptl. d. data (952 points) of WCOB + 2-butanol binary mixtures over a wide range [seven compositions; 0 â‰?(WCOB) mole fraction x â‰?1] between 0.1 and 140 MPa and 298.15 and 393.15 K are presented. The exptl. data were correlated using Tait and perturbed chain-statistical associating fluid theory (PC-SAFT) equations of state (EoS), to the knowledge, this is the 1st time that d. measurements for the WCOB + 2-butanol mixture are correlated using the famous PC-SAFT EoS. The Tait equation predicts successfully the d. with a global absolute average deviation (AAD) of 0.089%, while the PC-SAFT model correlates well the d. with a very small global AAD of 0.223% in each composition Also, contrary to the Tait equation, the PC-SAFT model can explain some interactions between fluid mols. From the exptl. data, the excess volumes VE were calculated and fitted using the Redlich-Kister equation with a very small global standard deviation of 7.49 × 10-5 cm3/mol, and VE show a pos. and sym. parabolic shape in all composition ranges. Finally, the isobaric thermal expansivity, αp, and the isothermal compressibility, κT, were derived from the Tait equation and their observed trend was as expected.

Owen, Rhodri N. published the artcileTowards a universal ion source: Glow Flow mass spectrometry, Recommanded Product: Methyl docosanoate, 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.
