Volatile constituents of Achillea serbica Nym.
(John Wiley and Sons Ltd, 2000)
The volatile constituents of Achillea serbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...
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 ...
Immobilization of glucoamylase via its carbohydrate moiety on macroporous poly(GMA-co-EGDMA)
(Elsevier, 2007)
We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well ...
Toluene Degradation in Water Using AlFe-Pillared Clay Catalysts
(Science Press, Beijing, 2009)
The catalytic wet peroxide oxidation (CWPO) of toluene on two bentonite-based AlFe-pillared clays (PILCs) with different iron contents was investigated. The PILCs were obtained using bentonite clay from Bogovina, Serbia. ...
Investigation of interactions between surface water and petroleum-type pollutants
(Ecomed Publishers, Landsberg, 2005)
Background, Aims and Scope. In oil spill investigations, one of the most important steps is a proper choice of approaches that imply an investigation of samples taken from different sedimentary environments, samples of oil ...
Plasma assisted degradation of phenol solutions
(Vacuum, 2008)
Solutions of 2-chlorophenol, 4-chlorophenol and 2,6-dichlorophenol in bidistilled and water from the river Danube were treated in plasma reactor. In this reactor, based on coaxial dielectric barrier discharge at atmospheric ...
Synthesis of the first thiazolidine-condensed five-, six-, and seven-membered heterocycles via cyclization of vinylogous N-acyliminium ions
(Synlett, 2009)
Synthesis of new thiazolidine-fused five-, six-, and seven-membered heterocycles through vinylogous N-acyliminium ion-cyclization sequence, involving positions 3 and 4 of the thiazolidine ring, is described. The formation ...
Surface modification of macroporous glycidyl methacrylate based copolymers for selective sorption of heavy metals
(Switzerland : Springer Nature, 2007)
Two samples of macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), poly(GMA-co-EGDMA), were synthesized by suspension copolymerization and modified with amines. Initial poly(GMA-co-EGDMA), and the ...
Adhesion characteristics and corrosion stability of epoxy coatings electrodeposited on phosphated hot-dip galvanized steel
(Elsevier, 2008)
The influence of hot-dip galvanized steel (HDG) surface pretreatment with phosphate coatings on the corrosion stability and adhesion characteristics of epoxy coatings electrodeposited on HDG steel was investigated. Phosphate ...
Study of forced degradation behavior of Eletriptan hydrobromide by LC and LC-MS and development of stability-indicating method
(Elsevier, 2009)
The objective of the present study was to report the stability profile of novel antimigrain drug Eletriptan hydrobromide based on the information obtained from forced degradation studies. The drug was subjected to acid ...
