One technique used to prepare nanoparticles material is Pulsed Laser Ablation in Liquid (PLAL), Silver Oxide (AgO) were prepared by using this technique, where silver target was submerged ultra-pure water (UPW) at room temperature after that Nd:Yag laser which characteristics 1064 nm wavelength, Q-switched, and 6ns pulse duration irradiated target. This preparation method study the effects of i...

The translating and rotating rod or disk of a conventional laser vaporization cluster source is replaced by a liquid metal target. The self-regenerating liquid surface prevents cavities from being bored into the sample by laser ablation. The laser beam strikes a near pristine surface with each pulse, resulting in signals with much better short and long term stabilities. While this approach cann...

Abstract High entropy metallic glass nanoparticles (HEMG NPs) are very promising materials for energy conversion due to the wide tuning possibilities of electrochemical potentials offered by their multimetallic character combined with an amorphous structure. Up until now, generation these HEMG NPs involved tedious synthesis procedures where generated particles were only available on highly spec...

Recently reported results on the behaviour of the tungsten under conditions expected in the Neutrino Factory target have strengthened the case for a solid target option for the Neutrino Factory. This paper gives a description of the measurements of the surface motion of tungsten wires, stressed by a pulsed current, using a Laser Doppler Vibrometer in order to measure tungsten properties at high...

Short pulsed laser is preferred to avoid the thermal damage in processing the heat sensitive material, such as carbon fiber reinforced plastic (CFRP). In this paper, a numerical model capturing both the material ablation and polymer matrix pyrolysis processes in pulsed laser processing is established. The effect of laser pulse length from ns order to μs order is studied. It was found that with ...

Inorganic nanoparticles (plasmonic nanoparticles, semiconductor-based quantum dots etc) are known to offer novel promising properties for biological sensing and imaging, as well as for therapeutics. However, these applications are often complicated by potential toxicity issues, arising as a result of inadequate purification procedures of nanoparticles obtained via synthetic pathways using toxic...

Ultra-short pulsed laser removal of thin biofilm contamination on different substrates has been conducted via the use of plasma-mediated ablation. The biofilms were formed using sheep whole blood. The ablation was generated using a 1.2ps ultra-short pulsed laser with wavelength centered at 1552nm. The blood contamination was transformed into plasma and collected with a vacuum system. The single...

Hybrid laser processing for precision microfabrication of hard materials, in which the interaction of a conventional pulsed laser beam and another medium on the material surface leads to effective ablation, is reviewed. The main role of the medium is to produce strong absorption of the nanosecond laser beam by the materials. Simultaneous irradiation with the ultraviolet (UV) laser beam and the ...
