ABSTRACT A new paradigm of Coulter counting is developed using electrohydrodynamic liquid jets in lieu of solid state pores as the sensing aperture. The electrohydrodynamic jet was successfully used to detect micron-sized particles through resistive pulse sensing. Similar to conventional Coulter counting, the relative current change is proportional to the particle-tojet volume ratio. Compared t...

The existence of nanosized particles at the workplace is not a new phenomenon . As early as in 1997, the Deutsche Forschungsgemeinschaft, Commission for the investigation of Health Hazards of chemical compounds in the work area, defined the term “ultrafine particles” in its List of Maximale ArbeitsplatzKonzentration (MAK) and Biologischer Arbeitsstoff-Toleranzwert (BAT) Values . The definition ...

The morphological description of fractal agglomerates is generally reduced to only two parameters, namely the mass dimension and its prefactor. In most evolved approaches, a stretching exponent also introduced, while packing factor preferred any case, current analytical morphology accurate for sufficiently large agglomerates, which due limited spatial extension clusters that are actually quasi-...
