Gyori, Eniko published the artcileSupercritical CO2 extraction and selective adsorption of aroma materials of selected spice plants in functionalized silica aerogels, Product Details of C11H16O2, the main research area is supercritical CO2 extraction squalene spathulenol adsorption silica aerogel.

Static supercritical fluid extraction has been used to concentrate the aroma materials of common herbs and spices. The technique has provided a higher number of components and cleaner extract than the one-step ethanol maceration. The one-step supercritical fluid extraction of the aroma compounds has been combined with their in situ adsorption in hydrophilic and hydrophobic silica aerogels. The extracts have been analyzed by a GC-MS technique and 55 aroma compounds have been identified. Most of the compounds have been adsorbed in both polar and apolar silica aerogels with no direct connection with the surface polarity. However, previously undetected compounds enriched to an anal. significant level, while others competed with each other for the active sites on the surface. Functionalized silica aerogels can be used as a new type of aroma storage materials and as selective and tuneable adsorbents for the extraction and enrichment of potentially active components from a complex matrix.

Blanco-Zubiaguirre, L. published the artcileTarget and suspect screening of substances liable to migrate from food contact paper and cardboard materials using liquid chromatography-high resolution tandem mass spectrometry, Computed Properties of 121-00-6, the main research area is food contact paper cardboard substance migration LC HRMS; Food contact paper and board materials; Liquid chromatography-high resolution mass spectrometry; Migration; Quantitative target analysis; Suspect screening; Tenax®.

This work describes the anal. of both target and non-target compounds in paper and cardboard materials together with the characterization of their migration to Tenax by means of liquid chromatog. coupled to both low (LC-QqQ) and high resolution tandem mass spectrometry (LC-q-Orbitrap), resp. To this aim, an entire anal. procedure was fully developed and validated for both matrixes: paper/cardboard and Tenax. A total of 97 chems., including photoinitiators, phthalates, biocides, antioxidants, etc., listed by the European Regulation, were found in the materials under study together with other substances not included in this list. Moreover, the majority of annotated substances were present in the simulant, giving evidence of their migration capacity. Migration percentages of 10 photoinitiators, 4 phthalates, bisphenol A, bis-(2-ethylhexyl) adipate, acetyltributyl citrate and caprolactam to Tenax were quantified. Despite not exceeding the established specific migration limit (SML) in any case, benzophenone, 4-phenylbenzophenone and bisphenol A concentrations in some paper and cardboard materials were very close to the SML values established by the EU legislation.

Xue, Wendong published the artcileResearch on the Comprehensive Evaluation Method for the Automatic Recognition of Raman Spectrum under Multidimensional Constraint, HPLC of Formula: 121-00-6, the main research area is Raman comprehensive evaluation automatic recognition multidimensional constraint.

Raman spectrum contains abundant substance information with fingerprint characteristics. Due to the huge variety of substances and their complex characteristic information, it is difficult to recognize the Raman spectrum accurately. Starting from dimensions like the Raman shift, the relative peak intensity, and the overall hit ratio of characteristic peaks, the authors the characteristics in the Raman spectrum were extracted and recognized, and these characteristics were analyzed from local and global perspectives and then a comprehensive evaluation method proposed for the recognition of Raman spectrum from the data fusion of the recognition results under multidimensional constraint. Based on the common spectrum database of the normal Raman and surface-enhanced Raman of thousands of substances, the authors analyzed the performance of the evaluation method. Even for the identification of spectra from instruments of low tech. specifications, the automatic recognition rate of the sample can reach 98% and above, a great improvement compared with that of the common identification algorithms, which proves the effectiveness of the comprehensive evaluation method under multidimensional constraint.

Nantaba, Florence published the artcileTemporal dynamics and ecotoxicological risk assessment of personal care products, phthalate ester plasticizers, and organophosphorus flame retardants in water from Lake Victoria, Uganda, COA of Formula: C11H16O2, the main research area is ecotoxicol risk assessment water pollution Lake Victoria Uganda; East africa; Flame retardants; Lake victoria; Personal care products; Plasticizers; Risk assessment.

For the first time the occurrence of 25 organic micropollutants (OMPs) including, eleven personal care products (PCPs), six phthalate ester plasticizers (PEPs) and eight organophosphorus flame retardants (OPFRs) was investigated in 72 water samples obtained from five bays in the Uganda sector of Lake Victoria. In addition, an assessment of the potential ecotoxic risk of the target OMPs to aquatic organisms was conducted. Water samples were analyzed for the target OMPs using gas chromatog. coupled with GC/MS. All the target PCPs were found in all the water samples with the exception of musk ketone and 2,6-di-tert-butylphenol. Triclosan, benzophenone, and 4-methylbenzylidine camphor were the most predominant PCPs. All the six plasticizers were found in all the water samples with di-Bu phthalate, and bis-(2-ethylhexyl) phthalate detected at the highest concentrations Tricresyl phosphate, tris-(2-chloroethyl) phosphate and tri-Ph phosphate were the most dominant OPFRs. The highest concentrations of OMPs were recorded in Murchison and Thurston Bays, presumably due to industrial wastewater effluents from the highly industrialized localities of the two Bays. Ecotoxicol. risk assessment showed that PCPs (triclosan, musk ketone, and 4-MBC), plasticizers (di-Bu phthalate, bis-(2-ethylhexyl) adipate and bis-(2-ethylhexyl) phthalate) and OPFRs (tricresyl phosphate, tri-Ph phosphate and tris-(2-chloroethyl) phosphate) pose a high ecotoxic risk to lives of aquatic organisms.
