Preparation and Characterization of ZnO Nanoparticles by Laser Ablation in NaOH Aqueous Solution
In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributio...
متن کاملStudy of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
متن کاملTreatment of the contaminated implant surface using the Er,Cr:YSGG laser.
Treatment of the contaminated implant surface by mechanical and chemotherapeutic means has met with mixed success. Incomplete surface debridement or alteration of the implant surface could compromise attempts at grafting and reintegration of the implant body. Development of a laser system operating at 2780 nm and using an ablative hydrokinetic process offers the possibility for more efficient d...
متن کاملSurface Decontamination by Dielectric Barrier Discharge Plasma
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
