This paper describes using KrF excimer laser for fabricating conducting graph on Polyvinylidene fluoride (PVDF) substrates. Any graph is machined by direct laser writing technique. Furthermore, the defect structure is prepared on this patterned surface where laser etching is carried out. Mask patterning is used to select the conducting area when the patterned sample is irra...$28.00

Presented at ICALEO 2009
The effect of grain size on the laser machinability of alumina (Al2O3) was examined in order to meet the demand of higher tolerances when laser machining advanced ceramics. Laser lines created in alumina samples fabricated by using progressively increasing sintering times showed a difference in the amount of damage produced along the edges of the channels that were created, with less damage in smaller-grained samples. The average line width of the samples decreased with increasing grai...$28.00

During laser cleaving of brittle materials with the controlled fracture technique, thermal stresses are generated. These induce the crack to form and extend it along the cutting path, which subsequently causes material separation. The fract...$28.00

Presented at ICALEO 2009
Ti-alloys used in prosthetic applications are mostly alloys initially developed for aeronautical applications, so their behavior was not optimized for medical use. A need remains to design new alloys for biomedical applications, where requirements such as biocompatibility, in-body durability, specific manufacturing ability, and cost effectiveness are considered. Materials for this applica...$28.00
