The aim of this study was to use gas chromatography-mass spectrometry (GC-MS) and APCI-MS techniques to detect adulteration in honey. The key volatile compounds in the headspace of the adulterated honey were marked by GC-MS and their representative fragment ions were utilised in scanning honey samples using the real-time APCI-MS system. The PLS models validated using independent data sets resulted in coefficient of the determination ((Formula presented.)) of 0.97 and 0.96 and root mean square error in prediction (RMSEP) of 2.62 and 2.45 for the GC-MS and APCI-MS data sets respectively. The most efficient volatiles from GC-MS analysis and their corresponding fragment ions m/z from APCI-MS data analysis were then identified and used to develop new PLS models to predict the level of adulteration. The best PLS model gave (Formula presented.) of 0.95 and RMEP of 2.60% in the independent validation set indicating that the model was very accurate in predicting the level of adulteration.

A facile, green and stereoselective approach for the synthesis of azlactones/oxazolones 3(a-q) has been developed. The protocol involves reaction of hippuric acid and substituted heterocyclic/aromatic aldehydes in ionic liquid [Et3NH][HSO4] to yield the desired 4-arylidene-2-phenyl-5(4H)-oxazolones in excellent yields (94-97%) with a high degree of purity. The remarkable feature of this pathway is that the ionic liquid eliminates the use of toxic and expensive acetic anhydride and is endowed with catalytic and medium engineering ability. This eco-friendly approach improved synthetic efficiency (94-97% yield), minimizing the production of chemical waste without using highly toxic reagents for the synthesis and more notably, it promoted the selectivity for Z-azlactones/oxazolones. Density functional theory (DFT) calculations revealed that the Z-isomer of compound 3a is stabilised by 2.32 kcal mol-1 more than the E-isomer. This synthetic scheme possesses diverse applicability and is compatible to a range of functional groups (electron donating/electron withdrawing).

A series of substituted benzofuropyrimidinones with pan-PIM activities and excellent selectivity against a panel of diverse kinases is described. Initial exploration identified aryl benzofuropyrimidinones that were potent, but had cell permeability limitation. Using X-ray crystal structures of the bound PIM-1 complexes with 3, 5m, and 6d, we were able to guide the SAR and identify the alkyl benzofuropyrimidinone (6l) with good PIM potencies, permeability, and oral exposure.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: Benzo[b]furan-2-carboxaldehyde, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4265-16-1, Name is Benzo[b]furan-2-carboxaldehyde, molecular formula is C9H6O2

A simple protocol for the synthesis of difluoromethylthiolated chromen-4-ones using elemental sulfur and ClCF2CO2Na as the difluoromethylthiolating agent is described. Three-component reactions of 2?-hydroxychalcones, ClCF2CO2Na, and sulfur under basic conditions using TEMPO as the oxidant afforded HCF2S-containing 4H-chromen-4-one and 9H-thieno[3,2-b]chromen-9-one derivatives in good yield. The protocol is practical and efficient, and the starting materials are cheap and readily available.

125-20-2, Name is Thymolphthalein, belongs to benzofurans compound, is a common compound. COA of Formula: C28H30O4In an article, once mentioned the new application about 125-20-2.

Concretes in biogas plants (BGP) are subjected to chemical damage through acids which are formed by microbiological processes. Four-year-old grass silage clamp and different concretes samples were analysed. The tests allow statements on the plant-specific damage potential and the performance of the concretes used. Acetic and lactic acids were produced in the grass silage clamp through the microbiologically-induced ensilaging process. Damage decreased inversely with pH despite the presence of rainwater (dilution effect) due to the greater microbiological activity. At pH < 4.0, significant damage (depth of 12.8 mm after four years) was found in the silage clamp. The damage potential of organic acids is based on the buffering effect (subsequent dissociation) and the high solubility of the resulting salts. If atmospheric oxygen was used inside the fermenter for desulphurisation, various bacteria of the genus Thiobacillus, such as the bacterium Halothiobacillus neapolitanus, at first produced elementary X-ray amorphous sulphur (S) and later sulphuric acid, which dissolved the hydrate phases of the hardened cement paste. The dissolved calcium reacted with sulphate to gypsum. Concretes with a low equivalent water/cement ratio, a low calcium-content in the hardened cement paste and incorporated steel fibres performed the best resistance. The results can contribute to the prevention of damage in future and for the development of new, more resistant concretes. Do you like my blog?

Combined blockade of IKr and IKs potassium channels is considered to be a promising therapeutic strategy for arrhythmia. In this study, we designed and synthesized 15 derivatives through modifying the hit compound 7 that was discovered by screening in-house database by whole-patch clamp technique. All of the compounds were evaluated on CHO and HEK 293 cell lines stably expressing hERG (IKr) and hKCNQ1/KCNE1 (IKs) potassium channels, and half of them exhibited improved dual IKr and IKs inhibitory effects compared to the hit compound. Compounds 7a and 7b with potent dual inhibitory activities were selected for further in vivo evaluations. Due to the preferable pharmacological behaviors, compound 7a deserved further optimization as a promising lead compound.

The green BCG/MgCl2/PEG-g-CDA powders were synthesized at different temperatures via liquid-phase reaction method. The microstructures of the synthesized powders were analyzed and characterized by FT-IR, XRD and ChemDraw software. The effects of synthesized temperatures on infrared emissivity properties of the powders in the wavelength range 3?5 mum were investigated systematically. It is found that the powders heated at 100 C exhibit the optimum crystallinity at room temperature and thus show the largest variation (0.4) in infrared emissivity with the test temperature varying from 50 C to 65 C. Furthermore, the mechanisms for the self-regulated infrared emissivity properties are also explored thoroughly. The variation of infrared emissivity with temperature is ascribed to the changes in resistivity, which is induced by the transformation of PEG-g-CDA between crystalline and amorphous as well as the molecular structure transition of BCG between quinone and lactone. Our results suggest that BCG/MgCl2/PEG-g-CDA powders are potential candidates for intelligent infrared camouflage.

In many processes proposed for biorefineries, recycling procedures, and industrial or agricultural production processes, residue is generated which could be further transformed by thermochemical conversion via gasification. The technology of dual fluidized bed steam gasification is capable of producing a valuable product gas out of such residue. The generated nitrogen-free product gas can be used for heat and power production and is suitable for separating gases (e.g. hydrogen). However, if the product gas is cleaned, its use as syngas is more beneficial for manufacturing renewable chemical substances, like synthetic natural gas, methanol, Fischer?Tropsch liquids, or mixed alcohols. This paper presents the results of experimental research from gasification test runs of different biogenic fuels, carried out with an advanced 100 kW pilot plant over the last 5 years at TU Wien. The focus is to provide an overview of measured results validated by mass and energy balances and to present key calculated performance indicating key figures of the test runs. In this way, the influence of various operational parameters and the composition of the product gas are evaluated. The presented results form the basis for the proper design of suitable gas-cleaning equipment. Subsequently, the clean syngas is available for several synthesis applications in future biorefineries.
