Gold(I)-Catalyzed Domino Cyclizations of Diynes for the Synthesis of Functionalized Cyclohexenone Derivatives. Total Synthesis of (-)-Gabosine H and (-)-6-epi-Gabosine H
(American Chemical Society (ACS), 2016)
1,6-Diynes with a t-butylcarbonate group in the propargylic position undergo gold(I)-catalyzed dominocyclization which affords alpha-hydroxycyclohexenones. The described sequence can be applied on functionalized, highly ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
Photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation of titanium in 12-tungstosilicic acid
(Elsevier, 2012)
In this paper, we have investigated photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation (PEO) of titanium in 12-tungstosilicic acid water solution and compared with photocatalytic activity ...
Purification and characterisation of Saccharomyces cerevisiae external invertase isoforms
(Elsevier Sci Ltd, Oxford, 2010)
Four external invertase isoforms (EINV1, EINV2, EINV3 and EINV4) from Saccharomyces cerevisiae were highly purified by isoelectric precipitation, ethanol precipitation, ion-exchange on QAE-Sephadex and gel filtration using ...
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 ...
Analysis of the competitive adsorption and mass transfer influence on equilibrium mass fluctuations in affinity-based biosensors
(Elsevier, 2013)
We analyze the fluctuations of the equilibrium adsorbed mass in affinity-based biosensors, considering adsorption-desorption and mass transfer processes of two molecular species which compete for binding to the same probe ...
Influence of manganese oxide on the activity of Pt/Al2O3 catalyst for CO and n-hexane oxidation
(Elsevier, 2006)
The influence of low loadings of MnOx on the catalytic activity for n-hexene and CO oxidation over highly dispersed Pt on alumina catalysts has been investigated. The applied deposition-precipitation method allows Mn to ...
Utilization of fruit processing industry waste as green activated carbon for the treatment of heavy metals and chlorophenols contaminated water
(Elsevier Sci Ltd, Oxford, 2017)
Plum stones, as a part of industrial and municipal organic waste, were used as a precursor for preparation of a low-cost activated carbon. Engineered, thermochemically-modified adsorbent was used to remove lead (Pb2+), ...
Antioxidative and immunomodulating activities of polysaccharide extracts of the medicinal mushrooms Agaricus bisporus, Agaricus brasiliensis, Ganoderma lucidum and Phellinus linteus
(Elsevier Sci Ltd, Oxford, 2011)
Partially purified polysaccharides were obtained from four medicinal mushroom species, Agaricus bisporus, Agaricus brasiliensis, Phellinus linteus and Ganoderma lucidum by hot water extraction, followed by ethanol ...
Open circuit potentials of metallic chromium and austenitic 304 stainless steel in aqueous sulphuric acid solution and the influence of chloride ions on them
(Corrosion Science, 2008)
Open circuit potential measurements and cyclic voltammetry of chromium and 304 stainless steel in deaerated aqueous H2SO4 solution of pH 1, without and containing NaCl in the concentration range 1-4 M revealed that chromium ...
