The effect of time and temperature on the growth and morphology of cupper oxide nanostructures
Journal Title: Iranian Chemical Communication - Year 2015, Vol 3, Issue 1
Abstract
Cupper Oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. The structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. SEM images show gradual development of hierarchical structures of copper oxide with different morphology. In order to study the effect of reaction time and temperature on the morphology of the CuO samples, experiments carried out at temperatures 0 °C and 25 °C for 10 min up to 12h. Results showed that the prepared samples exhibited some novel morphology such as nanorods, nanosheets, microflowers, Cubic shaped structures and Tulip flower-shaped structures.

Denture base polymers, poly methyl methacrylate improved using free radical copolymerization
Poly methyl methacrylate (PMMA) is the most common material used in Prosthodontics. Several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attemp...
DFT calculations on quetiapine hemifumarate as a pharmaceutical compound for the treatment of schizophrenia
In this work, the optimization calculations were carried out on quetiapine hemifumarat, 4, and its analogues, 1-5. These calculations were carried out using the B3LYP/6-31G(d) level of theory. The DFT calculations clarif...
Extraction and preconcentration of Pb(II) from water and soil samples using modified activated carbon
In this work, a new extractant was prepared by immobilizing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, (5-Br-PADAP), on the activated carbon and applied to extraction of Pb(II) prior to determination by flame...
