Biography
Julio Car (born 16/02/1993.) got his Master’s degree at the University of Natural Sciences in Zagreb, Croatia in the field of physics. During his education he participated in 3 International Olympiads in Astronomy and Astrophysics in China (2009.), Ukraine (2010.) and Poland (2011.). Currently, he is doing PhD in atomic and molecular physics at the Institute of physics in Zagreb. His field of study is laser ablation of materials and production of nanoparticles used for impregnation in polymers in order to achieve better surface properties as well as in photocatalysis.

Laser drilling of metals in water: A model
Author(s): Julio Car
Laser drilling of metals in water is essential method for synthesis of nanoparticles with adjustble size distribution and morphology given that there are many experimental parameters (energy, frequency, wavelength, pulse duration, number of pulses, width of the pulse...) which determine characteristics of obtained nanoparticles. One of the most important quantites dependent on these parameters are volumes of craters from which concentration and diameter of produced nanoparticles may be determined. This work shows that Gaussian profile of laser pulses used for drilling of craters projects itself into the Gaussian profile of obtained crater depth vs. radius dependence. Basis of the model is assumption that fluence dependence on width of the laser pulse has the same mathematical form as de... view more»
