A sequencing batch reactor-based system was developed for enhanced phosphorus (P) removal and recovery from municipal wastewater. The system consists of an iron-dosing SBR for P precipitation and a side-stream anaerobic reactor for sludge co-fermentation with food waste. During co-fermentation, ...

The factors that influence the solvatochromism and acid-base behaviour of 5-octadecyl-1-methyl-8-oxyquinolinium betaine (FOEHQ) and 7-octadecyl-1-methyl-8-oxyquinolinium betaine (SOEHQ) in aqueous micellar systems have been identified. This has been achieved by comparing the spectral and acid-ba...

In the present study we have investigated the effect of methyl substitution at various positions on the spectral and decay behavior of some quinolinium ions. The spectra reveal marked differences when methyl group is present at 7th and 8th positions. The non-radiative deactivation is also consid...

The adsorption of N-methyl 8-hydroxy quinoline methyl sulphate—a drug generally used to protect from sunburn—by natural and acid-treated sepiolite, has been investigated. Acid treatment led to partial dissolution of the fibres of the clay, mainly in the external surface of the crystallites. In...

The title compounds and related substances were prepared, characterised and tested as solvatochromic chelating agents. These reagents show large color changes with solvent, and the chelates, though insoluble in most common solvents, are also solvatochromic. Reagents with a 2-methyl group adjacen...

Development of agents that specifically kill cancer cells and simultaneously elicit antitumor immune response is a step forward in cancer therapy. Immunostimulation can result in eliminating of the cancer cells; immunotherapy is a promising approach in balancing the immune response by Treg. In t...

The degradation of cross-linked and linear poly(2-hydroxyethyl methacrylate) (pHEMA), was examined in vitro with J774.2 cells. pHEMA microbeads were prepared with both types of polymers. Only cells in contact with the microbeads increased their production of lysosomal enzymes (TRAcP and ANAE) an...

The synthesis of a number of new methacrylate esters containing aryl-oxycarbonyl group are described. The monomers produced from the reaction of corresponding aryl-oxycarbonyl methylchlorides with sodium methacrylate, were polymerized in 1,4-dioxane with AIBN as an initiator at 60 °C. The monom...

Female F344 rats exposed to 200 ppm methyl methacrylate for 6 h developed a lesion in the nasal olfactory epithelium which was characterised by degeneration and atrophy. The severity of the lesion was markedly reduced by pre-treatment of the rats with an intraperitoneal dose of 100 mg/kg bis-(p-...

A series of α-diimine Ni(II) and Pd(II) complexes containing bulky steric groups, {[(4-R-2,6-Ph2C6H2NC)2Nap]MX2} (Nap: 1,8-naphthdiyl, MX2 = NiBr2, R = F (4a); R = Cl (4b); R = Me (4c); R = n-Bu (4d) and MX2 = PdCl2, R = F (5a); R = Cl, (5b); R = Me (5c); R = n-Bu (5d)), {[4-F-2,6-Ph2C6H2NC(Me)...

The methacrylic monomer, 4-benzoylphenyl methacrylate (BPM) was synthesized by reacting 4-hydroxy benzophenone dissolved in methyl ethyl ketone (MEK) with methacryloyl chloride in the presence of triethylamine. The homopolymer and various copolymers of BPM with glycidyl methacrylate were synthes...

The substituted β-ketoiminato palladium(II) complexes, Pd[CH3C(O)CHC(NAr)CH3](Pph3)(Me) (1 Ar = α-napthyl, 2 Ar = fluorenyl), when was activated by methylaluminoxane (MAO), were used as highly active catalysts for methyl methacrylate (MMA) polymerization. The effects of temperature, co-catalys...

To investigate the influence of various pendants in comb-type copolymers on the low-temperature flowability of diesel fuel, a series of methacrylate-co-maleic anhydride copolymers R1MC-MA (R1 = C14, C16, C18) were synthesized. And C14MC-MA was aminated by R2NH2 (R2 = C14, C16, C18, phenyl, 1-nap...

Excellent adherence properties of blue mussels have been attributed to a catechol-containing amino acid, L-3,4-dihydroxyphenylalanine. This natural form of adhesion has been a source to develop bioadhesive polymers that adhere to biological interfaces. In this study, we describe a bioinspired ap...

The synthesis of new palladium(II) complexes of the type [Pd(A–NC–ph–CN–A)Cl2] (4a–e) (A = cyclohexyl (a), 2-isoprpropyl (b), pyrenyl (c), naphthyl (d), and 2,6-diisopropyl (e)) is described. The isolated γ-diimine ligands and their corresponding palladium(II) complexes were characterized ...

Theoretical calculations on tris(4-trifluoromethyltetrafluorophenyl)phosphine, 1, and spectroscopic studies of its complexes, trans-[PtCl2{P(C6F4CF3-4)3}2], 3, and trans-[RhCl(CO){P(C6F4CF3-4)3}2], 4, indicate that it is a poorer σ donor than tris(pentafluorophenyl)phosphine. The structures of ...

Ortho-tert-butylcalixarenes 3, 4 and 5 with exo-hydroxy groups were synthesised by tin tetrachloride-promoted condensation of 2,2′-dihydroxy-3,3′-di-tert-butyldiphenylmethane 6 with formaldehyde. While 1H NMR analysis of compounds 3, 4 and 5 revealed a considerable annular flexibility in CDCl3...

Adipose triglyceride lipase (ATGL) catalyzes the degradation of cellular triacylglycerol stores and strongly determines the concentration of circulating fatty acids (FAs). High serum FA levels are causally linked to the development of insulin resistance and impaired glucose tolerance, which even...
