Second-generation peroxides: The OZs and artemisone
(Treatment and Prevention of Malaria. Milestones in Drug Therapy, 2012)
The emergence of multi-drug resistant strains of Plasmodium falciparum has rendered many affordable antimalarials, such as chloroquine, much less effective in addressing the severe health issues in sub-Saharan Africa, ...
Purification and properties of midgut α-amylase isolated from Morimus funereus (Coleoptera: Cerambycidae) larvae
(Elsevier Science Inc, New York, 2008)
Using soluble starch as a substrate five isoforms of α-amylase were identified in a crude extract of Morimus funereus larvae. The main α-amylase (termed AMF-3) was purified by gel filtration chromatography and anion exchange ...
Degradation of methyl-phenanthrene isomers during bioremediation of soil contaminated by residual fuel oil
(Springer Heidelberg, Heidelberg, 2012)
Phenanthrene and methyl-phenanthrenes are major aromatic pollutants originating in particular from fuel oil. Phenanthrene is usually degraded faster than methyl-phenanthrenes under geological and environmental conditions. ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
Photoacoustic elastic bending method: Study of the silicon membranes
(28th International Conference on Microelectronics - Proceedings, MIEL 2012, 2012)
Photoacoustic (PA) amplitude and phase spectra vs the modulation frequency of the excitation optical beam were measured and analyzed by PA elastic bending method. The PA spectra were measured in a frequency range (from 20 ...
Preparation and photolysis of 2-diazo-6-oximino- and 2,6-bisdiazo-4-tert. Butylcyclohexanone
(Elsevier, 1967)
Reaction mechanism of diazoketone photolysie is assumed
to involve the formation ofd-keto-carbene intermediates, final products being dependent on the molecular structure and
reaction medium. Numerous example8 of ...
Synthesis and evaluation of several cathechol bioisosteres as potential dopamine receptor ligands
(Elsevier, 1991)
Derivatives of benzimidazole (I), benzimidazolone (II), benzimidazolethione (III), 2,3-dihydroxyquinoxaline (IV) and the noncyclic acetamide (V) and t rifluoroacetamide (VI) of the corresponding 1,2-pheny-lenediamiane were ...
Formic acid oxidation on Pt-Au nanoparticles: Relation between the catalyst activity and the poisoning rate
(Elsevier, 2012)
Pt-Au nanoparticles supported on high area carbon were prepared by simultaneous reduction of Au and Pt precursors and by reduction of Pt precursor on already prepared Au nanoparticles. The first method produced a solid ...
P-nitrophenol electro-oxidation on a btma(+)-bentonite-modified electrode
(Clay Minerals Soc, Chantilly, 2012)
Phenol and its derivatives arc regarded as 'priority pollutants' and p-nitrophenol (p-NP), in particular, is of great interest due to its toxicity and frequent presence in waste waters and fresh waters. Straightforward, ...
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
