Optical doping and damage formation in AlN by Eu implantation

Implantation Damage Formation in GaN and ZnO

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

A new approach to photovoltaic junction formation by using pulse implantation doping technique

2014 The paper presents the first demonstration of a new method of forming photovoltaic p-n junction in silicon by the « Pulse Implantation Doping (PID) » technique. In this technique, an intense ion pulse provides both the dose necessary for doping and the portion of energy required to recrystallize a damage-free, doped surface layer. The ion beam pulses within the range of one microsecond and...
