The synthesis of 2-(N-aryolamino)benzothiazoles and 2-(N-aryolamino)benzimidazoles has been accomplished in the presence of copper catalyst. These reactions involve C-S and C-N cross-coupling reaction. All electron donating and withdrawing substituent's readily underwent the reaction to giv...

A new ionic polyacetylene with N-benzoylpyridinium substituent was prepared by the activation polymerization of 2-ethynylpyridine by using benzoyl chloride without any additional initiator or catalyst. This reaction proceeded well in homogeneous manner to give a high yield of the polymer (yield:...

A series of 4-amino-2-methylquinoline and 4-aminoquinazoline derivatives, including the reference NOP antagonist JTC-801, were synthesized by an alternative pathway and their in vitro pharmacological properties were investigated. 3-Substitution of the quinoline ring resulted very critical for af...

The International Organization for Standardization (ISO) recently released technical specifications about minimum reporting requirements in soundscape studies and methods for data collection (ISO/TS 12913-2:2018). The document provides an informative annex with three alternative methods: two are...

The upward trend in the residential sector of energy use has significant consequences in terms of environmental impacts. Determining the carbon metric (CM), as part of the whole carbon footprint of a building, contributes to quantify the carbon emissions related to the building's use stage....

During the last decade Campylobacter has been the most commonly reported gastrointestinal bacterial infection in humans in the European Union. The use of a sensitive detection method based on enrichment of Campylobacter spp. is often needed when examining foods. However, as background flora deve...

Absolute quantitative measurements of partial pressures with quadrupole mass spectrometers in industry have become increasingly important in the past decade. On the other hand, there is no broadly accepted method to calibrate quadrupole mass spectrometers and partial pressure measurements are no...

The reference method for the detection and enumeration of L. monocytogenes in food (Standards EN ISO 11290-1&2) has been validated by inter-laboratory studies in the frame of the Mandate M381 from European Commission to CEN. In this paper, the collaborative studies led in 2013 on 5 matrices (col...

Hydrophobically modified poly(vinyl alcohol)s (hm-PVAs) with various alkyl chain lengths (3–12) were synthesized and were coated on poly(propylene) (PP) films. The blood compatibilities of the hm-PVAs-coated films were evaluated. The C6-PVA-coated PP film showed suppressed platelet adhesion as ...

IntroductionAlcohol consumption is related to several diseases and injuries that accelerate the ageing process and increase the mortality and morbidity risk. The soluble form of the α-Klotho gene (called S-Klotho) is widely considered as a powerful anti-ageing biomarker.

As the key chiral intermediate of luliconazole, (S)-2-chloro-1-(2, 4-dichlorophenyl) ethanol ((S)-CPEO) was prepared from 2-chloro-1-(2, 4-dichlorophenyl) ethanone (CPE) using a tetrad mutant alcohol dehydrogenase (A94T/F147L/L199H/A202L) from Lactobacillus kefir (LK-TADH) coupled with glucose d...

The cholesterol esterase and lipoprotein lipase catalyzed hydrolyses of the water-soluble substrate p-nitrophenyl butyrate are competitively inhibited by butaneboronic acid and phenylboronic acid. Phenyl-n-butylborinic acid has been synthesized and characterized as an ultrapotent transition stat...

Diethylglyoxal bis(guanylhydrazone) (DEGBG), a novel analog of the antileukemic agent methylglyoxal bis(guanylhydrazone) (MGBG) was synthesized. It was found to be the most powerful inhibitor of yeast S-adenosylmethionine decarboxylase (AdoMetDC) so far studied (Ki approx. 9 nM). This property, ...

A chiral iridium complex catalyzed a consecutive and enantioselective [2+2+2] cycloaddition of polyynes to give axially chiral compounds. Intermolecular reaction of tetraynes, possessing aryl groups on their termini, with protected but-2-yne-1,4-diols gave C2-symmetrical quateraryl compounds. In...

The tosylalanine ester of 3-hydroxy-5-phenylpyrrole (HOPPy) is localized on reagent strips (Ames LEUKOSTIX) and used diagnostically to test urine for the presence of human leukocyte elastase (HLE) as an indication of urinary tract infection. We have determined the kinetic constants for the HLE-c...

In the present study, the degradation of ionic liquid 1-butyl-1-methylpyrrolidinium chloride has been carried out through sulfate radicals. These radicals were generated by different methods of activation of the commercial peroxymonosulfate (PMS) formulation, Oxone®. Among them, the electro-assi...

The mining industry is known to be a major producer of sulfate-rich waters that are harmful to aquatic systems, accelerate acid mine drainage formation and hinder the reuse and recycling of process water. In recent years, many treatment techniques have been studied and developed to treat sulfate...

This experimental study investigates the influence of H+ and Cl− ions on the leaching procedure of the iron ore tailings (IOT) using different lixiviants including various ratios of H2SO4/NaCl, and HCl. By using HYDRA/Spana software, the formed species of iron were identified as FeCl3, Fe(SO4)2−...

The chloride diffusion induced reinforcement corrosion seriously threatens the durability of concrete construction in marine environments. This paper investigates the effects of sulfate and magnesium ion in simulated seawater on the chloride transportation behavior and binding capacity of Portla...

Precipitation of iron as hematite from acidic sulphate-chloride solutions was studied in a batch reactor at 150 °C. Several factors that either increase or decrease the extent of hematite precipitation (such as: sulphuric acid, chloride, seed, ferric iron, pre-neutralization, arsenic(V) and cop...
