A practical review of the use of laser ablation lor the deposition of thin films of oxide superconductors and metals is presented. Details of the design and operation of a laser ablation deposition system are discussed, together with the influence of operating parameters such as laser wavelength and power density on the film growth, with the a:m of assisting the researcher oeginning to use andl...

This paper reports on the production of Ag nanoparticles (AgNPs) in a water solution based two-phase pulsed laser procedure view therapeutic ophthalmological applications requiring AgNPs size ≤10 nm with narrow distribution. Nanoparticles this scale are capable penetrating complex ocular barriers, thus ensuring effective non-invasive drug delivery to retina. Moreover, irritation, which is curre...

In this study we used a laser ablation technique for preparation of silver nanoparticles. The fabrication process was carried out by ablation of a silver plate immersed in palm oil. A pulsed Nd:YAG laser at a wavelength of 1064 nm was used for ablation of the plate at different times. The palm coconut oil allowed formation of nanoparticles with very small and uniform particle size, which are di...

introduction: to compare endovenous laser ablation (evla) and radiofrequency ablation (rfa) in different legs in the same individual in patients with venous insufficiency. methods: sixty patients with bilateral saphenous vein insufficiency were included. evla or rfa was applied to one of the patient’s legs and rfa or evla to the other leg. results: evla and rfa complications were hyperemia at 2...

Titanium oxide nanoparticles (TiO2) were produced by pulsed Nd:YAG laser ablation in water under the effect of an external magnetic field. Various techniques such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy Dispersive (EDX), transmission (TEM), UV–Vis spectroscopy, and Raman spectroscopy used to characterize TiO2 nanoparticles. The XRD analysis titani...

Tungsten inert gas (TIG) welding, also called as gas tungsten welding 1. (a) Schematic of TIG welding Process (b) Variety of tungsten electrodes. The activated TIG (ATIG) welding process mainly focuses on increasing the depth of penetration and the reduction in the width of weld bead has not been paid. Tungsten inert gas welding, TIG is widely applied in manufacturing process for different The ...

introduction: laser-assisted vaporization of prostate tissue by means of the potassiumtitanyl- phosphate (ktp) laser is in clinical use. alternative laser sources are available but are lacking clinical experience.the 980 nm wavelength diode laser provides good hemostasis, in addition to a more rapid ablation rate. the aim of this study is approving the capability, feasibility, and good post-ope...

Abstract We elaborated a technique of pulsed laser ablation in gas mixtures (He-N 2 ), maintained under residual pressures 0.5–5 Torr to deposit silicon (Si)-based nanostructured films on substrate. show that the deposited can exhibit strong photoluminescence (PL) emission with position peaks depending pressure ambient and ratio gases mixture. Nanostructured prepared pure He exhibited band infr...

The bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, lambda = 1,064 micron; Hol:YSGG, lambda = 2.10 micron; and Erb:YAG, lambda = 2.94 micron) and two continuous-wave lasers (Nd:YAG, lambda = 1.064 micron; and CO2, lambda = 10.6 micron), were studied. All laser ablations were performed in vitro, using moist, freshly dissected calvarium of guinea pig ...

The formation of Ni nanostructures to act as catalysts in the growth of carbon nanotubes is reported. The changes in the surface morphology of Ni produced by three methods thermal evaporation and annealing of thin films, pulsed laser ablation and annealing of Ni, and the use of metal containing macromolecules have been investigated by atomic force microscopy and scanning electron microscopy.
