Conceptual reorganization and the construction of the chemical reaction concept during secondary education
(1998)Aspects of 40 pupils' (aged 12-18) conceptual reorganization and change, related to the construction of the chemical reaction concept were studied. Data were collected with the Free Categorization Task and the Interview ... -
Conformational analysis of two novel cytotoxic C2-substituted pyrrolo 2,3-f quinolines in aqueous media, organic solvents, membrane bilayers and at the putative active site
(2012)We have performed: (i) conformational analysis of two novel cytotoxic C2-substituted pyrrolo[2,3-f]quinolines Se and 5g in deuterated dimethylsulfoxide (DMSO-d(6)) utilizing NOE results from NMR spectroscopy; (ii) molecular ... -
The s-Hole Phenomenon of Halogen Atoms Forms the Structural Basis of the Strong Inhibitory Potency of C5 Halogen Substituted Glucopyranosyl Nucleosides towards Glycogen Phosphorylase b
(2012)C5 halogen substituted glucopyranosyl nucleosides (1-(beta-D-glucopyranosyl)-5-X-uracil; X=Cl, Br, I) have been discovered as some of the most potent active site inhibitors of glycogen phosphorylase (GP), with respective ... -
Synthesis and structural characterization of neutral "3+2" oxorhenium and oxotechnetium complexes of the 2-mercaptoethyl-N-glycine (SNO)/2,2 '-bipyridine (NN) mixed ligand system
(2007)Neutral. hexacoordinated "3 + 2" mixed ligand oxorhenium (1) and oxotechnetium (2) complexes of the general formula MO [SNO][NN]. where M = Re or Tc-99, SNO is 2-mercaptoethyl-N-glycine and NN is 2,2'-bipyridine (bpy), ...
