Preparation and Study of Molecular Structure of Copper Ions Doped in a Silica Xerogel Matrix
The silica xerogel is prepared using copper source; 0.02 mol of Cu(NO3)2.3H2O that has been added to 1 mol TEOS (tetraethyl orthosilicate). The Copper ions are doped to silica matrix by the sol gel method and determination of total molar ratio of components with a reported molar ratio of H2O /TEOS(R) = 6.2. In this method, the acidity the of reaction (pH) depends on the catalyst type in the hyd...
متن کاملGe nanodots embedded in a silica matrix
The properties of GeSiO films consisting of Ge nanodots embedded in SiO2 matrix, prepared by sol-gel and magnetron sputtering methods, followed by an adequate thermal annealing, are studied and discussed in this paper. Structural investigations were performed by means of transmission electron microscopy and Xray photoelectron spectroscopy. In the sol-gel films one finds amorphous Ge nanodots di...
متن کاملIsolation and characterization of microsatellite loci in the Guanacaste tree, Enterolobium cyclocarpum.
We isolated nine microsatellite loci from the Guanacaste tree (Enterolobium cyclocarpum) and optimized them for future research on breeding populations of this species. Loci were screened across 53 individuals from one population and were shown to be variable with the number of alleles per locus ranging from five to 15. Polymorphic information content ranged from 0.420 to 0.900 and observed het...
متن کاملAntinutrtional Factors, Nutritive Value and in vitro Gas Production of Foliage and Fruit of Enterolobium cyclocarpum
Enterolobium cyclocarpum foliage is yet to be accepted by ruminants in Nigeria as recommended for intensive garden use. In a comparative study, the nutritive value of the leaf, seed, pod and fruit was investigated by proximate, secondary metabolites and in vitro gas production methods. Proximate composition showed that all the samples were quite high in crude protein (10.4-21.7%), ether extract...
متن کاملThe impact of landscape disturbance on spatial genetic structure in the Guanacaste tree, Enterolobium cyclocarpum (Fabaceae).
We examined spatial genetic structure (SGS) in Enterolobium cyclocarpum (the Guanacaste tree), a dominant tree of Central American dry forests in 4 sites in Guanacaste Province, Costa Rica. In disturbed dry forest sites (e.g., pastures), E. cyclocarpum is primarily dispersed by cattle and horses, whose movements are restricted by pasture boundaries. The study sites varied in tree densities and ...
