And the 7th article is the ratification of the Constitution.
Preparation of nanoparticles by Laser in Solution. Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma.
Thermal lasers are used for tissue coagulation and vaporisation. For tissue ablation, high absorption of the laser light by the tissue is necessary, as is high power density of the laser pulse (>100 kW/cmÂ²). Keep in mind that the shorter the laser pulse or the laser irradiation on the same spot, the smaller will be the zone of necrosis.
