Cation-pi interaction with transition-metal complex as cation
(Elsevier Science Bv, Amsterdam, 1999)
A novel type of cation-pi interaction, where a transition-metal complex cation interacts with a pi-system, is predicted here. The theoretical calculations on the [Co(NH3)(6)](3+)-C6H6 system presented demonstrate that a ...
Rhizome and root yield of the cultivated Arnica montana L., chemical composition and histochemical localization of essential oil
(Elsevier Science Bv, Amsterdam, 2012)
Arnica montana (L) is a medicinal plant whose flower heads are widely used for the topical treatment of bruises and sprains in phytopharmaceutical preparations. Despite being cultivated for flower heads production for a ...
Kinetic spectrophotometric method for gold(III) determination
(Elsevier Science Bv, Amsterdam, 2005)
The kinetic spectrophotometric method for Au(III) determination was developed and validated. It was based on the catalytic effect of gold on the oxidation of methylene blue B (3,7di-(dimethyl amino)-10-dehydro-phenotiazin ...
Metal ligand aromatic cation-pi interactions
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
Cation-pi interactions are important noncovalent bonding forces. This review covers a special type of cation-pi interactions, the metal ligand aromatic cation-pi (MLACpi) interaction, where ligands that are coordinated to ...
Production and properties of the highly efficient raw starch digesting alpha-amylase from a Bacillus licheniformis ATCC 9945a
(Elsevier Science Sa, Lausanne, 2011)
Highly efficient raw starch digesting alpha-amylase was produced after 24 h of batch fermentation of Bacillus licheniformis ATCC 9945a in laboratory bioreactor at 37 degrees C. The enzyme was purified by gel filtration ...
Application of non-supervised pattern recognition techniques to classify Cabernet Sauvignon wines from the Balkan region based on individual phenolic compounds
(Academic Press Inc Elsevier Science, San Diego, 2016)
Phenolic compounds in sixteen Cabernet Sauvignon wines from different wine-growing sub-regions in the Balkan region were investigated using HPLC with DAD and fluorescence detector and spectroscopic analysis, as well as ...
Capillary zone electrophoresis determination of fluoride in seawater using transient isotachophoresis
(Springer Heidelberg, Heidelberg, 2018)
We developed capillary zone electrophoresis (CZE) with indirect UV detection for the determination of fluoride (F-) in seawater using transient isotachophoresis (tITP) as an on-line concentration procedure. A method of ...
A reexamination of the propensities of amino acids towards a particular secondary structure: classification of amino acids based on their chemical structure
(Springer, New York, 2008)
The correlation between the primary and secondary structures of proteins was analysed using a large data set from the Protein Data Bank. Clear preferences of amino acids towards certain secondary structures classify amino ...
Distribution of perfluoroalkyl compounds in Osaka Bay and coastal waters of Western Japan
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Perfluoroalkyl acids (PFAAs) including perfluoroalkyl sulfonates (PFSAs) and perfluoroallcyl carboxylates (PFCAs) were analyzed in sediment samples taken from Ajifu Waterway in Osaka city, from Osaka Bay, and from Kagoshima ...
Synthesis, structure, and reactivity of fluorous phosphorus/carbon/phosphorus pincer ligands and metal complexes
(Royal Soc Chemistry, Cambridge, 2005)
Reactions of the diphosphine 1,3-C6H4(CH2PH2)(2) and fluorous alkenes H2C=CHRfn (R-fn = (CF2)(n-1)CF3; n = 6, 8) at 75 degrees C in the presence of AIBN give the title ligands 1,3-C6H4(CH2P(CH2CH2Rfn)(2))(2) (3-R-fn) and ...
