Broda, Kurtis N

A new method of examining mass and number distributions of nanoscale refractive black carbon (rBC) particles has been developed. This method will be useful for atmospheric scientists conducting semi-continuous measurement of atmospheric rBC. The new method uses a Centrifugal Particle Mass...

Background: The COVID-19 pandemic has shown us that our infection prevention and control (IPC) knowledge has some glaring gaps on what best ways to treat dental patients, leading to a flurry of research to understand the best mitigation strategies to reduce aerosols. One of these strategies...

Particulate matter emitted from two direct injection engines has been characterized by morphology, volatility, mass-mobility exponent, effective density, and size distribution using tandem measurements from a centrifugal particle mass analyzer (CPMA) and differential mobility analyzers (DMA). The...

The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...

Facemask use has been a key public health measure in response to the SARS CoV-2 pandemic; they are used to reduce airborne transmission of the disease amongst the public. The facemasks used by the public are non-medical in nature and therefore are not regulated like medical masks. Cloth masks,...

This research is focused towards improving techniques used to measure particulate emissions from aircraft engines, on two fronts: first, to characterize and quantify the mixing state of particulate emissions; and second, to calibrate black carbon mass instruments with a traceable mass...

The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...

Infectious respiratory diseases, caused by viruses and bacteria that attack the respiratory system, constitute a serious threat in public health around the world. Pathogens can be transmitted in the air though large droplets or aerosols. As aerosols can linger in the environment for a prolonged...

A recent in vitro study demonstrated a non invasive method to enhance local deposition in a small airway by controlling the angular position of magnetic high aspect ratio particles. This technique could mitigate the challenge of providing sufficient therapeutic effects when using aerosolized...

Most current models for the deposition of aerosol particles in the human lung are based on a Lagrangian reference frame, which is ill-suited for modeling transient eects. Deposition models based on an Eulerian reference frame are much better at capturing instantaneous time-dependent eects, though...
