This study assessed the effects of additions an essential oil (EO), composed ricinoleic acid, cardol, cardanol, and apple pomace, on fermentation quality aerobic stability alfalfa silages. The experimental treatments consisted T1) (control), T2) with EO, T3) (75%) pomace (25%), T4) (25%) T5) (50%) (50%), T6) T7) (75%), T8) EO. addition decreased silage pH compared control (P <0.01). Apple at...
The discharge of industrial effluent constituting high orthophosphates and organic pollutants in water receiving bodies compromises freshwater quality perpetuates eutrophication. In this study, an anaerobic–aerobic sequencing batch reactor (SBR) under activated sludge was investigated for chemical oxygen demand (COD) removal from brewery wastewater. Raw wastewater samples were collected on a da...
Two solutions, one consisting of bpy/TEMPO/NMI and the other bpy/ABNO/NMI (bpy =2,2'-bipyridyl; TEMPO = 2,2,6,6-tetramethylpiperidine N-oxyl, ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl; NMI = N-methylimidazole), in acetonitrile are shown to have good long-term stability (≥1 year) under air at 5 °C. The solutions may be combined in appropriate quantities with commercially available [Cu(MeCN)4]OTf t...
[reaction: see text] Palladium(II) complexes bearing a single N-heterocyclic carbene ligand serve as effective catalysts for the aerobic oxidative cyclization of alkenes with pendant sulfonamides. The use of carboxylic acid cocatalysts (AcOH and PhCO(2)H) often leads to significant improvements in catalyst stability and product yield and enables catalytic turnover to be achieved with air, rathe...
Select triarylsulfonium salts constitute ionic liquids with outstanding long-term, high-temperature aerobic stability (no mass loss in 90 days at 300 C in air), making them among the most thermally stable organic materials known. A detailed analysis of their thermophysical properties reveals that lowering melting points in these salts by increasing ion size or lowering ion symmetry cannot be as...
The aerobic oxidation of sulfite thus provides a magnified manometric response to the chain initiating event. Advantage was taken of this circumstance to develop an ultrasensitive assay for milk xanthine oxidase (5). The data obtained were consistent with the hypothesis that xanthine oxidase, when acting on purine substrates, initiates the aerobic oxidation of sulfite by the generation of free ...
