An analytical system to quantify agaritine present in Agaricus blazei, Agaricus bisporus, and other food mushrooms was established using high pressure liquid chromatography combined with mass-spectroscopy (HPLC–MS). Water extracts from dried, homogenised mushrooms were kept at differing tempera...

With the aim to develop an eco-friendly, efficient and stable photocatalyst, the present work reports the synthesis of Ag3PO4/LaCO3OH (AP/LC) heterojunction photocatalysts. Different weight ratios of AP/(x wt% LC) were tested to find the best composition for superior photocatalytic activity for ...

Coal gangue and phenol are two main pollutants in coal mining and processing. Using coal gangue as raw material, a series of Cu modified ZSM–5 (Cu/ZSM–5) catalysts were developed to remove phenol through heterogeneous Fenton–like reaction. This procedure implies the concept of waste control b...

Exposure of white wine to oxygen can cause detrimental effects, such as loss of sensorial characteristics. New antecedents, to the oxidation of wine, establish the importance of the formation of metallic complexes with compounds with adjacent hydroxyls. These complexes could reduce iron, promoti...

In this work, we have reported synthesis of AgBr/BiOBr photocatalyst supported on graphene (Gr) using facile precipitation method. AgBr/BiOBr/Gr was characterized using various spectral techniques like FESEM, TEM, XRD, FTIR, XPS, Raman and PL analyses. AgBr/BiOBr/Gr had improved visible light ab...

In this work the catalytic performance of Cu(5%)/Al2O3 catalysts prepared by wet impregnation and calcined at three different temperatures, 400 °C (WI 400), 650 °C (WI 650) and 900 °C (WI 900), was analyzed. These materials were tested in the phenol wet oxidation reaction using H2O2 (0.22 or ...

In this study, we presented a novel nanofiltration membrane fabrication strategy through rapid co-deposition of a versatile platform – metal phenolic networks (MPNs) and piperazine (PIP) on a porous substrate followed by trimesoyl chloride (TMC) crosslinking. Inspired by the catechol chemistry,...

Acetonic crude phenolic extracts of six Georgia peach cultivars were prepared and separated into low- and high-molecular-weight (LMW and HMW) fractions by Sephadex LH-20 column chromatography. Further characterization via RP-HPLC-ESI-MS identified the main phenolics as hydroxycinnamates, (+)-cat...

A series of catalysts with p-LaFeO3/n-ZnO heterostructure were designed and prepared by hydrothermal method. The structure, surface topographies, optical properties and interfacial interactions of these photocatalysts were analyzed by XRD, SEM, TEM, PL, Uv–vis DRS, XPS, COD, TOC etc., indicatin...

To explore the role of phenolic compounds in oral aroma release during wine tasting, four rosé wines supplemented with three types of commercial phenolic extracts and a control wine were evaluated. Wines were aromatized with a mixture of six target aroma compounds. –In vivo oral aroma release ...

Phenolic contaminants existed widely in ecological environment. Due to the various structure and functional groups, the interaction behavior of phenolic organic compounds with adsorbent was complex and changeable. Therefore, the exploration of adsorption and competition about phenolic compounds ...

The modification of a molecule that was identified as highly efficacious in the previous studies could considerably improve the biological activity of the resulting compounds. While targeting lanosterol 14-α demethylase, the molecular modelling studies convinced that the extension of the phenyl...

We have developed a short and highly efficient synthetic strategy towards the hitherto hardly known 3,5- and 3,6-disubstituted 2,3,4,7-tetrahydro-1H-azepine scaffold via a ring-closing metathesis approach utilizing inexpensive and readily available starting material such as methyl acrylate and a...

Phytohormone conjugation is one of the mechanisms that maintains a proper hormonal homeostasis and that is necessary for the realization of physiological responses. Gretchen Hagen 3 (GH3) acyl acid amido synthetases convert indole-3-acetic acid (IAA) to IAA-amino acid conjugates by ATP-dependent...

The reactions of hexachlorocyclotriphosphazene, N3P3Cl6, with mono (1 and 2) and bis(4-fluorobenzyl) diamines (3-5), FPhCH2NH(CH2)nNHR (RH or FPhCH2–), produce mono (1a and 2a) and bis(4-fluorobenzyl) monospirocyclophosphazenes (3a–5a). The tetraaminomonospirocyclophosphazenes (1b–2d) are obt...

Preparations of 2-(4-fluorobenzyl)-6-phenylimidazo[2,1-b][1,3,4]thiadiazole (3a) and its chlorophenyl derivative (3b) are described. Preliminary analysis was done spectroscopically by means of 1H NMR, 13C NMR spectra, mass spectra and elemental analyses. Further the structures were confirmed by ...

In recent years several potent HIV-1 integrase (IN) inhibitors have been identified and after the successful clinical use of raltegravir, they have gained a definitive place in the treatment of HIV-1 infection. Yet, there is a continuous effort to design newer inhibitors that target different st...
