We report the design, fabrication, and experimental characterization of an externally-fed, silicon batchfabricated MEMS electrospinning planar array with as many as 9 steady-operating emitters in 1 cm – more than a 7-fold increase in emitter density compared to state-of-the-art MEMS multiplexed electrospinning sources. The device simultaneously generates multiple nanofiber jets at 20 kV or less...

We present mixed gauge R-matrix Floquet calculations of multiphoton ionization of Li within a single active electron local model potential. The laser frequency ranges from 15 000 to 15 800 cm, and at least three photons are needed to ionize the electron in the 2s ground state. We found that the measured ionization rate as a function of photon frequency results from ionization processes in diffe...
