Study of Fibroblast Cells Behavior on the Acrylic Acid Co2 Pulsed Laser Grafted Silicone Elastomer for Tissue Engineering Application

Synthesis of Al2O3-ZrO2 Nanocomposite by Mechanical Activated Self-propagating High Temperature Synthesis(MASHS) and Ignited via Laser

By consideration of unique properties of composite Al2O3-ZrO2 such as high toughness, high wear resistant and relative low thermal expansion, in this study, nanocomposite of Al2O3-ZrO2 was produced by Mechanical activated Self propagating High-temperature Synthesis (MASHS) using laser beam for ignition. First Al and ZrO2 powders were mixed in the mole ratio of 1:1 and milled for 1, 3 and 6 hour...

CO2 and diode laser for excisional biopsies of oral mucosal lesions. A pilot study evaluating clinical and histopathological parameters.

PURPOSE The present pilot study evaluates the histopathological characteristics and suitability of CO2 and diode lasers for performing excisional biopsies in the buccal mucosa with special emphasis on the extent of the thermal damage zone created. PATIENTS AND METHODS 15 patients agreed to undergo surgical removal of their fibrous hyperplasias with a laser. These patients were randomly assign...

Design and Application of a Photoacoustic Sensor for Monitoring the Laser Generated Stress Waves in Optical Fiber

Measurement of stress transients generated by a 400ns pulsed HF laser in an infrared fluoride glass fiber has been made using fast time – response piezoelectric film transducer. Acoustic signals up to 12 mV with frequencies ranging in megahertz generated by 21 mJ laser pulse when passed through the fiber axis in the linear region. It is shown that useful information such as onset of non - linea...

افروزش سریع- شوکی رهیافتی نوین برای همجوشی محصور سازی اینرسی

 A new concept for inertial confinement fusion called fast-shock ignition (FSI) is introduced as a credible scheme in order to obtain high target gain. In the proposed model, the separation of fuel ignition into two successive steps, under the suitable conditions, reduces required ignitor energy for the fuel ignition. The main procedure in FSI concept is compressing the fuel up to stagnation. T...
