Experimental investigations of void dynamics in a dusty discharge

Dust charge fluctuations in a magnetized dusty plasma.

Charging currents of electrons and ions to a spherical dust grain in a uniform magnetized dusty plasma have been examined. It is found that the external magnetic field reduces the charging currents, thereby decreasing the dust charge fluctuation damping of a low-frequency electrostatic wave in a dusty plasma.

Quantification of nanoscale density fluctuations by electron microscopy

Most cancers are curable if they are diagnosed and treated at an early stage. Recent studies suggest that nanoarchitectural changes occur within cells during early carcinogenesis and that such changes precede microscopically evident tissue alterations. It follows that the ability to comprehensively interrogate cell nanoarchitecture (e.g., macromolecular complexes, DNA, RNA, proteins and lipid m...

Dusty plasma diagnostics methods for charge, electron temperature, and ion density

Diagnostic methods are developed to measure the microparticle charge Q and two plasma parameters, electron temperature Te, and ion density ni, in the main plasma region of a dusty plasma. Using video microscopy to track microparticles yields a resonance frequency, which along with a charging model allows an estimation of Q and Te. Only measurements of microparticle position and velocity are req...
