The kinetics of phenol degradation by immobilized pseudomonas sp in a repeated-batch process [PDF]
, 2007 The best operating conditions for phenol degradation by immobilized Pseudomonas sp in packed column were determined, and then evaluated in repeated batch cultures. The maximum degradation rate occurred in i) the support with 1.0 cm diameter or less, ii)

Advanced Engineering Materials, EarlyView.The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Electrochemical Investigation of Phenol Oxidation by a TiO2/GAC Based Packed-Bed Electrode Reactor
International Journal of Electrochemical Science, 2018 In this work, TiO2/GAC was prepared by sol-gel method and employed as particulate electrode for efficient phenol oxidation. The X-ray Diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analysis reveal the titanium dioxide loaded on GAC exists ...

Effects of Gabaergic phenols on phospholipid bilayers as evaluated by 1H-NMR [PDF]
, 2013 The phenols propofol and thymol, and lately carvacrol, eugenol and chlorothymol, have been shown to act as positive allosteric modulators on GABAA receptor, which is the main inhibitory receptor of the central nervous system.

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories
Advanced Engineering Materials, EarlyView.Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

International Journal of Electrochemical Science, 2017 The Cu-AC (AC: activated carbon) and Cu/Ce-AC composite materials were synthesized using a one-pot sol-gel method. The surface microstructure and composition of the resulting samples were characterized by Brunauer–Emmett–Teller (BET) specific surface ...

Synthesis and study of polyhydroxylated phenol derivatives with potential cosmetic and phytoiatric applications [PDF]
, 2013 Tyrosinase (polyphenol oxidase, E.C. 1.14.18.1) and laccase (phenol oxidase, E.C. 1.10.3.2) are multifunctional copper-containing enzymes, that are keys in melanin biosynthesis, melanisation in animals and browning in plants.

Preparation and some properties of nylon-4,2 [PDF]
, 1984 An attempt was made to produce a new short-chain alphatic polyamide nylon-4,2. This polyoxamide can be prepared by polycondensation of tetramethylene diamine and diethyl oxalate.
