The changes in structure periods the microscale strongly affect initial bacterial adhesion.
Starting from a simple concept, transferring the shape of an interference pattern directly to surface material, method Direct Laser Interference Patterning (DLIP) has been continuously developed in last 20 years. From lamp-pumped high power diode-pumped lasers, DLIP permits today for achievement impressive processing speeds even close 1 m<sup>2</sup>/min. The objective: improve performance surfaces by use periodically ordered micro- and nanostructures. This study describes years evolution...

We discuss a new simple InGaAs-InAlAs avalanche photodiode (APD) with planar buried multiplication region. Some of the advantages compared to standard APDs are as follows: 1) The thickness and charge control regions accurately controlled by molecular beam epitaxy growth in contrast diffusion process; 2) InAlAs is material (avalanching faster electrons) instead InP slower holes); 3) gain has lower noise figure than that for InP; 4) guard ring not required; 5) fabrication p-i-n detector; 6)...
