Characterization and first results from LACIS-T: a moist-air wind tunnel to study aerosol–cloud–turbulence interactions [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
The interactions between turbulence and cloud microphysical processes have been investigated primarily through numerical simulation and field measurements over the last 10 years.

Effects of cleaning spray use on eyes, airways, and ergonomic load

open access: yesBMC Public Health, 2023
Background Cleaning workers are exposed to chemicals and high physical workload, commonly resulting in airway problems and pain. In this study the response in the upper airways and the physical workload following airborne and ergonomic exposure of ...

Atmospheric aerosol attenuation effect on FD data analysis at the Pierre Auger Observatory [PDF]

open access: yesforthcoming EPJ Web of Conferences, 2019, 2019
The atmospheric aerosol monitoring system of the Pierre Auger Observatory has been operating smoothly since 2004. Two laser facilities (Central Laser Facility, CLF and eXtreme Laser Facility, XLF) fire sets of 50 shots four times per hour during FD shifts to measure the highly variable hourly aerosol attenuation to correct the longitudinal UV light ...

Lung function and self-rated symptoms in healthy volunteers after exposure to hydrotreated vegetable oil (HVO) exhaust with and without particles

open access: yesParticle and Fibre Toxicology, 2022
Background Diesel engine exhaust causes adverse health effects. Meanwhile, the impact of renewable diesel exhaust, such as hydrotreated vegetable oil (HVO), on human health is less known. Nineteen healthy volunteers were exposed to HVO exhaust for 3 h in

Techniques for measuring atmospheric aerosols at the High Resolution Fly's Eye experiment [PDF]

open access: yesAstropart.Phys.25:74-83,2006, 2005
We describe several techniques developed by the High Resolution Fly's Eye experiment for measuring aerosol vertical optical depth, aerosol horizontal attenuation length, and aerosol phase function. The techniques are based on measurements of side-scattered light generated by a steerable ultraviolet laser and collected by an optical detector designed to

Simple fabrication of an electrospun polystyrene microfiber filter that meets N95 filtering facepiece respirator filtration and breathability standards

open access: yesJournal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023
The COVID‐19 pandemic led to a backlog of filtration material for N95 Filtering Facepiece Respirators (FFRs). An alternative face mask filter material is presented, consisting of an unsupported, nonwoven layer of uncharged polystyrene microfibers. This microfiber material meets NIOSH N95 FFR filtration and breathability requirements, demonstrates ...

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave
