X-ray analyses, spectroscopic and magnetic properties of [Cu4(succinato)(tpmc)2](ClO4) 6·2C2H5OH·4H2O and [Cu2(C6H5COO)tpmc](ClO4) 3·0.5CH3OH·0.5H2O complexes
(Elsevier, 2008)
[Cu4(succinato)(tpmc)2](ClO4) 6 · 2H2O (tpmc = N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8,11-tetraa zacyclotetradecane, succinato = dianion of succinic acid) has been prepared and characterized by elemental analysis, ...
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 ...
High-yield synthesis of substituted and unsubstituted pyridinium salts containing a 4-oxothiazolidine moiety
(Georg Thieme Verlag Kg, Stuttgart, 2008)
A new series of unsubstituted and substituted pyridinium salts bearing a 4-oxothiazolidinyl moiety has been prepared by an efficient rearrangement of 2-(l-bromoalkylidene)thiazolidin-4-ones. The process is based on three ...
Oxidation of n-hexane over Pt and Cu-Co oxide catalysts supported on a thin-film zirconia/stainless steel carrier
(Catalysis Communications, 2008)
The complete oxidation of n-hexane in air over a stainless steel foil (SS) coated with a thin film of ZrO2 (SS/ZrO2), SS/ZrO2/Pt, SS/ZrO2/La2O3/CuCo and SS/ZrO2/La2O3/CuCo/Pt catalysts has been investigated. The ZrO2 films ...
Preparation of silver(I) complexes with itaconic acid-based hydrogels for biomedical application
(Materials and Manufacturing Processes, 2009)
Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity ...
Identification of secretory compounds from the European callipodidan species Apfelbeckia insculpta
(Springer, Dordrecht, 2009)
Defensive secretions of the callipodidan species Apfelbeckia insculpta contain a p-cresol as the main component and phenol in traces. This is the first identification of these compounds in a European callipodidan species. ...
The kinetics of ethanol adsorption from the aqueous phase onto zeolite NaZSM-5
(Springer, New York, 2008)
The kinetics of the isothermal adsorption of ethanol from an aqueous solution onto a hydrophobic zeolite of the NaZSM-5 type in the temperature range 298-333 K was investigated. Specific shape parameters of the adsorption ...
