Natural products with a sulfated scaffold have emerged as antifouling agents with low or nontoxic effects to the environment. In this study 13 sulfated polyphenols were synthesized and tested for antifouling potential using the anti-settlement activity of mussel (Mytilus galloprovincialis) plantigrade post-larvae and bacterial growth inhibition towards four biofilm-forming bacterial strains. Re...

Stability and reusability are important characteristics of advanced catalysts for wastewater treatment. In this work, for the first time, sulfate radicals (SO4∙-) with a high oxidative potential (Eo = 2.5-3.1 V) were successfully activated from persulfate by a Fe78Si9B13 metallic glass. This alloy exhibited a superior surface stability and reusability while activating persulfate as indicated by...

BACKGROUND Occupational and environmental factors may be a cause of nonasthmatic eosinophilic bronchitis (NAEB). The diagnosis of occupational NAEB requires evidence of sputum eosinophilia. Nevertheless, a minority of patients are not able to produce suitable sputum specimens. METHODS This case report describes a 25-year-old woman, working as a hairdresser since the age of 20 years and handli...

Abstract Grafting of styrene (S) onto biopolymer Sodium Alginate (NaAlg) via free-radical polymerization forming (NaAlg-g-PS), using potassium persulfate K 2 S O 8 (KPS) as initiator. Fourier-transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance ( 1 H-NMR) characterized the formed grafted copolymer scanning electron microscope (SEM) to show changes in surface morphology ...

A slow-release fertilizer is important to improve soil conditions and enhances food security through continuous plant supply. With urea as a nitrogen source, kaolin carrier, acrylic acid reaction monomer, potassium persulfate an initiator, N, N '- methylene bisacrylamide crosslinking agent, under the action of cyclohexane sorbitan monostearate, based was synthesized by reverse suspension method...
