Airborne viruses, such as COVID-19, cause pandemics all over the world. Virus-containing
particles produced by infected individuals are suspended in the air for extended periods …

Electric agglomeration is a useful method to improve fly-ash particle collection efficiency in
traditional electrostatic precipitators (ESPs) by increasing particle diameter and achieving …

Personal monitors based on unipolar diffusion charging (miniDiSC/DiSCmini, NanoTracer,
Partector) can be used to assess the individual exposure to nanoparticles in different …

The accuracy of instruments measuring the alveolar lung deposited surface area (LDSA)
concentration based on unipolar diffusion charging has been assessed. Monodisperse …

We investigated the effect of particle morphology on unipolar diffusion charging of
nanoparticle agglomerates consisting of multiple primary spheres. In the unipolar diffusion …

Abstract Comparisons between the Engine Exhaust Particle Sizer Spectrometer (EEPS) and
scanning mobility particle sizers (SMPS) have shown that the EEPS underestimates size …

Growing concerns related to the adverse health effects of airborne ultrafine particles (UFPs;
particles smaller than 300 nm) have highlighted the need for field-portable, cost-efficient …

A new scheme for periodical technical inspection (PTI) of diesel-engine exhaust based on
the measurement of particle number (PN) concentration was recently introduced in several …

The generation and emission characteristics of fine particulates (PM2. 5) from three 300 MW
power plant circulating fluidized bed boilers were investigated. One boiler had an external …

We have developed an instrument, Universal NanoParticle Analyzer (UNPA), for quasi-
online measurement of gas-borne nanoparticle agglomerates. The UNPA utilizes a …
