Laser ablation of solid substrates in a water-confined environment
Laser ablation of Si under a water surface has been investigated. The laser used is a KrF excimer laser, which has a wavelength of 248 nm and a pulse duration of 23 ns. It is found that the laser abla...

An electromagnetic micromotor has been developed that combines microcoils and magnetic microtips as stator elements and individual permanent magnet single domain particles as rotors. The three-phase stator microcoils (with poles separated by 100 µm) are positioned outside the fluid, and the rotor (a 40 µm long, 1 µm diam permanent magnet) spins in aqueous solution 50 µm from the stator. The small size and essentially disposable rotors make the magnetic micromotor attractive for use in microfluidics systems for various physical, chemical, and biological applications. ©2001 American Institute of Physics.
