Investigation of cytocompatibility of surface-treated cellulose nitrate films by using plasma immersion ion implantation
The alpha-particle sensitive colorless cellulose nitrate films (commercially available as LR 115 films from DOSIRAD, France) have been proposed as cell-culture substrates for alpha-particle radiobiological experiments. Cytocompatibility of the substrate is a key factor to the success of such experiments. The present work aims to investigate the cytocompatibility of surface-treated cellulose nit...
متن کاملInfluence of nitrogen ion implantation on the nanostructure and corrosivity of Ni/stainless steel substrates
Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...
متن کاملRecent developments and applications of plasma immersion ion implantation
Plasma immersion ion implantation ~PIII! is an established technique in some niche microelectronics applications, such as synthesis of silicon on insulator. In other applications, such as shallow junction formation by plasma doping, trench doping, and others, PIII possesses unique advantages over conventional techniques. In the last few years, there have been significant breakthroughs in these ...
متن کاملEffect of welding parameters on pitting corrosion rate of pulsed current micro plasma arc welded AISI 304L sheets in 1N HCl
Austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. In the case of single pass welding of thinner sections of this alloy, Pulsed Current Micro Plasma Arc Welding (PCMPAW) has been found bene...
متن کاملApplication of a Pulsed , RF - driven ) Multicusp Source for Low Energy Plasma Immersion Ion Implantation
The multicusp ion source has the capability of producing large volumes of uniform, quiescent, high density plasmas. Due to the versatility of the multicusp source, a plasma chamber suited for plasma immersion ion implantation (PIII) was readily constructed. Conventional PIII pulses the bias voltage applied to the substrate which is immersed in a CW mode plasma. However, in the interest of findi...
