Strontium titanate polycrystalline thin films were prepared by sequent deposition of three TiO2/SrO/TiO2 layers using spray pyrolysis technique. Deposition parameters such as: precursor solution, deposition temperature, flow rate of solution and annealing conditions were optimized to obtain homogeneous transparent films. Prepared thin films have granular microstructure. The optical transmittan...
During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

Addressing the issue of energy in contemporary Iranian architecture is very important at all stages of planning, design, construction and operation, and the effort to coordinate and interact with the environment is always one of the foundations of sustainable construction. On the other hand, much of the citychr('39')s surface is composed of worn-out areas with high levels of energy consumption....
the multilateral trading system as a sub-system of the present international system from its beginning as gatt in 1947, after scond world war, until now have been criticized by different countries. with the conversion of gatt into the wto in 1994, not only dissatisfaction of the countries with the performance of multilateral trading system have not gone away, but in many cases also have increas...

The population of the study are all companies listed in Tehran Stock Exchange. Data collected and calculated by using Excel software Eviews 7 been ...
Conductive transparent ZnS/M/ZnS, (M = Au, Ag, Cu, Al) nano-structures have been simulated by optimization layers thickness, and gold, silver, copper, and aluminum materials were used as a metal layer and zinc sulfide for dielectric layers. Then the optimum simulated structure has been fabricated on a glass substrate by thermal evaporation. The crystallinity properties of the structures, such a...
