Phenol formaldehyde (PF) resins are widely used as wood adhesives in the industrial production of exterior-grade plywood panels, oriented strand board panels and particleboards due to their superior performance including high bonding strength, heat resistance, excellent water resistance and chemical stability1. However, phenol, one raw material for the synthesis of PF resins, is a petroleum-bas...

Five novel complexes were prepared by reacting 2-((E)-(tert-butylimino)methyl)phenol (HL2) with Ln(NO3)3xH2O (Ln = Gd and Dy ; x 6 5, respectively) LnCl3-6H2O Nd, Dy). The crystal structures of the former two Ln(III) nitrate are isostructural coordination sphere is composed three monodentate HL2 ligands bonded to metal centre through phenolic oxygen atom ions coordinated in a bidentate fashion....

The cytochrome P450 (CYP) isoforms involved in xenobiotic metabolism are enzymes whose substrate selectivity remains difficult to predict due to wide specificity and dynamic protein-substrate interactions. To uncover the determinants of specificity for cytochrome CYP2C9, a novel library of benzbromarone (bzbr) inhibitors was used to reevaluate its pharmacophore. CoMSIA was used with the bzbr li...

background and objectives: dairy companies always try to increase the quantity and quality of milk production. according to the positive impact of different plants on milk production of cattle, this study was carried out to standardize a galactogogue herbal mixture based on its total phenol and flavonol contents and antioxidant activity.  methods: a mixture of galega officinalis l. and nigella ...

The present study analyses the potential of acid treated chitosan for simultaneous co-adsorptive removal of phenol and cyanide from a binary waste water solution. The effects of parameters like pH, temperature, initial concentration, adsorbent dose, and adsorbent size were studied. At an optimum pH of 8, temperature of 300C, initial phenol and cyanide concentration of 200 mg/L and 20 mg/L respe...

Phenol biodegradation using acclimated activated sludge was investigated in batch and fedbatch cultures with variable initial concentrations of phenol and biomass. The batch experimental data show a cell growth after phenol exhaustion, making the use of a conventional Haldane model, for which specific growth rate μ = 0 when substrate S = 0, inadequate to describe biomass growth profiles. On the...

Two pyridylphenols with intramolecular hydrogen bonds between the phenol and pyridine units have been synthesized, characterized crystallographically, and investigated by cyclic voltammetry and UV/Vis spectroscopy. Reductive quenching of the triplet metal-to-ligand charge-transfer excited state of the [Re(CO)3(phen)(py)](+) complex (phen = 1,10-phenanthroline, py = pyridine) by the two pyridylp...

We investigated the effects of phenolic and phenol compounds on 3,3',5-L-125I-triiodothyronine (125I-T3) binding to purified Xenopus laevis transthyretin (xTTR) and to the ligand-binding domain of X. laevis thyroid hormone receptor beta (xTR LBD), on T3-induced metamorphosis in X. laevis tadpoles and on the induction of T3-dependent reporter gene in a X. laevis cell line. Of the halogenated phe...

An efficient procedure and green route has been developed by using eco-friendly green synthesized palladium nanoparticles (Pd-NPs) as reusable heterogeneous nanocatalyst (Pd@nanocat) for the synthesis of diaryl ethers from the cross coupling reaction of the aryl halides with the phenol in the presence of dimethylsulfoxide (DMSO) as a solvent at 110 oC under natural ligand condition capped Pd-NP...
