Covalently Bound

The spectroscopic and solution properties of trimethylgermanium nitrate have been determined and compared with those of other known Group IV alkyl nitrates. The vibrational spectra show that the nitrato group is covalently bound to the germanium atom in a unidentate manner. Ultraviolet spectra and conductivity measurements indicate that the compound behaves as a 1:1 electrolyte in water and dimethylsulfoxide, but is a non-electrolyte in methyl cyanide, nitromethane, and ethyl acetate. Attempts to prepare methylgermanium trinitrate are also described.

Technological Significance

There is a wide range of experimental results related to dislocations in diamond, group IV, II-VI, III-V semiconducting compounds, but few of these come from isolated, well-characterized individual dislocations. We are here concerned with only those results obtained in a transmission electron microscope so that the dislocations responsible were individually imaged. The luminescence properties of the dislocations were studied by cathodoluminescence performed at low temperatures (~30K) achieved by liquid helium cooling. Both spectra and monochromatic cathodoluminescence images have been obtained, in some cases as a function of temperature.There are two aspects of this work. One is mainly of technological significance. By understanding the luminescence properties of dislocations in epitaxial structures, future non-destructive evaluation will be enhanced. The second aim is to arrive at a good detailed understanding of the basic physics associated with carrier recombination near dislocations as revealed by local luminescence properties.

The purpose of this project is to study the anti-diabetic effect of on a diabetic rat model. A total of Twenty male Sprague rats were used and it randomly distributed into four groups which are Group I: , Group II: negative control, Group III: and Group IV: and . In diabetic model were induced with via injection at the dosage of 65mg/kg. and FBG (Fasting Blood Glucose) level of diabetic rats were assessed every three days. Blood was collected via cardiac puncture at day 21 after the induction of treatment. Insulin level of the rats was assessed with the Mercodia Rat Insulin ELISA kit. FBG level of group I (12.16 ±3.96, p<0.05) and group IV (11.34 ±3.67, p<0.05) were significantly decreased. Meanwhile, the for all rats did not show any significant increase. However, the insulin level was escalated in group IV (0.74+0.25, p<0.05) significantly. The present study shows that the and the combination of and lowered blood glucose level and enhanced insulin secretion.
