Isomers in the Chemistry of Germanium Heterometallic Clusters
Sixteen isomers of heterometallic germanium clusters have been analysed in this review. There are two types of isomerism, distortion (x 15) and cis – trans (x 1) and cis – isomer contains two crystallographically independent molecules. Distortion isomers, differing only by degree of distortion in Ge – L, Ge – M (M = metal) distances and L – Ge L (L = ligand) angles. The data are discussed with ...
متن کاملassessment of deep word knowledge in elementary and advanced iranian efl learners: a comparison of selective and productive wat tasks
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولSimultaneous Separation of Nitroaniline Isomers with Water - in - Oil Microemulsion
Thin-layer chromatography of nineteen amines has been performed on silica gel layers with a water-in-oil microemulsion (sodium dodecyl sulphate + water + heptane + n-pentanol, 8.0 g + 8.0 mL + 160.0 mL + 25.0 mL) as mobile phase. The effect of the basicity of the amines on their RF values was examined. The proposed thin layer chromatographic method was used to separate isomers of nitroaniline f...
متن کاملLi(+)-induced selective gelation of discrete homochiral structural isomers derived from L-tartaric acid.
Two chiral structural isomers have been synthesized by molecular engineering of L-tartaric acid. In the presence of LiOH isomer forms a thermally stable, fluorescent gel which exhibits interesting nano-cluster morphology, anomalous optical and rheological properties whilst forms a non-fluorescent solution under similar conditions. The current-voltage (I-V) curve followed a non-linear trend, rat...
