Immobilization of invertase and glucoamylase on a macroporous copolymer of etyleneglycoldimethacrylate and glycidyl methacrylate and potential applications in biotechnology / Imobilizacija invertaze i glukoamilaze na makroporoznom kopolimeru glicidilmetakrilata i etilenglikoldimetakrilata i njihova potencijalna primena u biotehnologiji
(Hemijska industrija, 2003)
The optimal conditions for the immobilization of invertase and glucoamylasewere found via their carbohydrate moiety on a macroporous copolymer of ehtyleneglycoldimethacry late and glycidylmethacrylate. Almost all of the ...
Synthesis and water solubility of novel fullerene bisadduct derivatives
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
The synthesis of four classes of bisadduct derivatives of C-60 is reported. The solubility of the new compounds in aqueous solvents is enhanced and is among the highest ever reported for fullerene derivatives. ((C) Wiley-VCH ...
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 ...
Synthesis of scopin acetate and 6,7-didehydrohyoscyamin. Intramolecular phenylsulfenylation of a nonactivated methylene group of ethyl N-demethyl-3-O-(phenylthio)tropine-N-carboxylate
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
The synthesis of scopin acetate (6b) and 6,7-didehydrohyoscyamine (17) was achieved by using tropine (5) as the starting compound. Formal (phenylthio)-radical transfer to the nonactivated 6-position of ethyl N-demethyl-3 ...
Modifications of fullerenes extractions and chromatographies with different solvents
