Titanium (Ti) has beneficial effects on growth, physiology and metabolism of plants. On the other hand, there is a high concern to use the nano-fertilizers with technological progress. In this respect, a hydroponic experiment, was designed in which Ti and nano-titanium (N-Ti) were added to the nutrient solution (NS) in two concentrations of 1 and 2 mg/L the NS without adding treatments was cons...

In order to evaluate the effect of sugarcane (Sacharum officinarum L.) filter muds and chemical and biological fertilizers application on macro- and micronutrient elements and some heavy metals (Pb and Cd) absorption by canola (Brassica napus L.) grains, a factorial experiment was conducted in 2012 in the Experimental Farm of Ramin (Mollasani) Agriculture and Natural Resources University of Kho...

Ammonium nitrate (AN) is widely used in fertilizers, civilian explosives and military explosives. Due to crystalline phase transitions and density changes of AN in the ambient conditions, its usage as oxidizer in solid propellants has some limitations as compared to ammonium perchlorate (AP). Several methods have been introduced to overcome these problems. In the present paper, the phase transi...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
