In spite of the fact that more than five decades have passed since the invention of laser, some topics of laser-matter interaction still remain incompletely studied. One of such topics is plasma impact on the overall phenomenon of the interaction and its particular OPEN ACCESS Micromachines 2014, 5 1345 features, including influence of the laser-excited plasma re-radiation, back flux of energet...

conclusions radiofrequency ablation may be used successfully in the treatment of parathyroid adenoma when a patient cannot tolerate surgery. case presentation a 47-year-old patient was referred to our hospital (namazi hospital, shiraz, iran) in april, 2015 with intracranial hemorrhage, as well as high serum calcium and pth (parathyroid hormone) levels (12.1 mg/dl and 1062 pg/ml, respectively), ...

Iron oxide nanowires are synthesized by photochemical method through nanosecond pulsed laser ablation of iron powder in liquid media. The synthesis is tried using various wavelengths (248 and 532 nm) of pulsed laser at different liquids (water, ethanol, methanol, isopropanol and glycol). The solution of iron oxide nanowires is obtained only in methanol when the iron powder (size < 60 μm) is irr...

Micro size craters were created by interaction of nanosecond laser beam with titanium target in liquid media. The dimension of crater i.e. depth and width is important in some applications such as micromachining. When the interaction occurs in liquid environment, the ablated materials from the target expand into the liquid. The ablated material can affect the interaction process if the ablated ...

in this study, laser induced breakdown spectroscopy (libs) is used for qualitative analysis of healthy and carious teeth. the technique of laser ablation is receiving increasing attention for applications in dentistry, specifically for the treatment of teeth such as drilling of micro-holes and plaque removal. in the process of ablation a luminous micro-plasma is normally generated which may be ...
