The origin of the enhanced activity of Pt/zeolites for combustion of C2-C4 alkanes
(Elsevier Science, 2007-04)
The deep oxidations of ethane, propane and butane were studied on Pt supported on MgO, alumina, and zeolites KL, HY, ZSM5, and Beta. The catalyst activities were evaluated through both conversion versus temperature (light-off ...
Three novel Indium MOFs derived from diphenic acid: synthesis, crystal structures and supramolecular chemistry
(Royal Society Of Chemistry, 2011)
Calix[4]arene amine modified silica: From fundamentals to new recyclable materials for the removal of chlorophenoxy acids from water
(Royal Society of Chemistry, 2015-03)
Two molecular receptors based on calix[4]arenes and their interaction with chlorophenoxy acid herbicides in solution and in the solid state have been investigated. From 1H NMR studies it is shown that the conformational ...
Proton transfer from 2-naphthol to aliphatic amines in supercritical CO 2
(American Chemical Society, 2011-12)
The proton transfer from 2-naphthol to aliphatic amines was studied in supercritical CO 2 (scCO 2) and in cyclohexane as reference solvent, by absorption and fluorescence spectroscopy and by time-resolved emission. Irradiation ...
Alkaline phosphatases: In silico study on the catalytic effect of conserved active site residues using human placental alkaline phosphatase (plap) as a model protein
(American Chemical Society, 2020-12)
The metalloenzymes from the alkaline phosphatase (AP) superfamily catalyze the hydrolysis and transphosphorylation of phosphate monoesters. The role of several amino acids highly conserved in the active site of this family ...
Optimization of β-cyclodextrin-based extraction of antioxidant and anti-browning activities from thyme leaves by response surface methodology
(Elsevier, 2018-11)
Thyme (Thymus vulgaris) has been demonstrated to extend the shelf-life of food products, being also a potential source of bioactive compounds. The aim of this research was to optimize the ultrasound assisted extraction ...
Thermodynamic Guidelines for the Design of Bimetallic Catalysts for Oxygen Electroreduction and Rapid Screening by Scanning Electrochemical Microscopy. M−Co (M: Pd, Ag, Au)
(American Chemical Society, 2005-01)
We propose guidelines for the design of improved bimetallic (and related) electrocatalysts for the oxygen reduction reaction (ORR) in acidic media. This guide is based on simple thermodynamic principles assuming a simple ...
Pretreatment of an induced mycelium-bound lipase from Arpergillus niger MYA 135 improves its hydrolytic and synthetic activity
(Springer, 2013-02-02)
Whole-cell enzymes have been used as biocatalysts in a variety of reactions, such as free fatty acid production and the synthesis of fatty acid esters. In the present study, enzyme pretreatments with PEG, MES, Tween 80, ...
ADP ribosylation factor 6 (ARF6) promotes acrosomal exocytosis by modulating lipid turnover and Rab3A activation
(American Society for Biochemistry and Molecular Biology, 2015-04)
Regulated secretion is a central issue for the specific function of many cells; for instance, mammalian sperm acrosomal exocytosis is essential for egg fertilization. ARF6 (ADP-ribosylation factor 6) is a small GTPase ...
Photodegradation of nitroaromatic compounds by the UV/H2O2 process using polychromatic radiation sources
(Royal Society of Chemistry, 2002-12)
The UV–H2O2 process, a standard advanced oxidation process (AOP) for water treatment, has been applied to the degradation of a series of nitroaromatic compounds (nitrobenzene, 1-chloro-2,4-dinitrobenzene, 2,4-dinitrophenol, ...
