The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...

coni nanowires were deposited by pulsed electrodeposition technique into porous alumina templates. the effect of off time between pulses (toff) and reductive/oxidative time (treduc/oxid) on the microstructure and magnetic properties of the coni nanowires were investigated. maximum coercivity and squareness were obtained for samples fabricated at treduc/oxid= 0.5 ms and toff =400 ms. the coerciv...

according to the english literature, various lasers and light sources (i,g. argon ion lasers, pulsed ktp lasers, diode lasers and nd:yag lasers, pulsed dye laser(pdl), intense pulsed light sources (ipls) are applicable for the treatment of different vascular lesions. these conditions are the most important indication for laser therapy. this review summarizes the current literature on ipl with r...

background: this study is the first research investigating the possible effect of pulsed power signals on the characteristics of cortical bone by comparing the mechanical properties of this type of bone pre and post expose to pulsed power. methods: a positive buck-boost converter was applied to generate adjustable high voltage, high frequency pulses (up to 500 v and 10 khz). the functional beha...

the lethality of pulsed ultra-violet (uv) rich light for the inactivation of pathogenic bacteria has been investigated. a low pressure xenon filled flash lamps that produced uv intensities have been used. the pulsed operation of the system enable the release of electrical energy stored in the capacitor into the flash lamp within a short time and produces the high current and high peak power req...
