Laser beam shaping is a key element in achieving better accuracy and resolution. Currently, there are two main methods for shaping a beam: one method uses two lenses to output a homogeneous beam with no power control. This method requires time consuming calibration of the lenses and can not accept o.....

Controlled drug delivery systems offer numerous advantages compared to conventional dosage forms including improved efficacy, reduced toxicity, and improved patient compliance and convenience. Controlled release systems aim to improve the effectiveness of drug therapy. This improvement can take the.....

Current approaches for detecting tunnels, activities in tunnels or tunnel excavation include electromagnetic induction sensors or acoustic ones to detect mechanical waves, and radar-type waves propagating between two boreholes. All of the approaches mentioned above are limited to large tunnels (>1m .....

Polyacenes are actually a chain of benzene rings (see figure). It is widely believed that polyacenes would have unprecedented properties: non-linear optics, substantial mechanical strength (similar to Kevlar™) and high directional (anisotropic) conductivity; i.e. conductive in one dimension/directio.....
