Presented at ICALEO 2011
Sinusoidal surface texturing and roughness modification generated on aluminum and stainless steel alloy substrates using a diode-pumped pulsed fiber laser are investigated as a pre-processing step for improved adhesive bonding. Different processing parameters are modified in order to assess their effect on the resulting surface topology; a power of 9.5 W, pulse width 200 ns, beam diameter s...$28.00

Presented at ICALEO 2011
With an ageing population demand on medical facilities is growing, especially for bio-implants. Therefore, there is a need for cheaper, more efficient implants. This paper details how CO2 and KrF excimer lasers can be employed to modulate osteoblast cell growth on nylon 6,6 in relation to laser-modified wettability characteristics. Through patterning the contact angle, θ, increased by up to 19°, indicating the presence of a mixed state wetting...$28.00

Presented at ICALEO 2011
The biodegradable polymer such as poly(L-lactic acid) (PLLA) is promising in drug delivery applications because its chemical structure allows it to hydrolyze into non-toxic substances in the human body. In such applications, drugs are embedded in a polymer matrix and released at the rate at which it degrades. PLLA degradation rate of is a strong ...$28.00
