Practicalities and Driving Dynamics of a Real Driving Emissions (RDE) Euro 6 Regulation Homologation Test

open access: yesEnergies, 2019
One of the most important sources of air pollution, especially in urban areas, is the exhaust emissions from passenger cars. New European emissions regulations, to minimize the gap between manufacturer-reported emissions and those emitted on the road ...

Measurement of PM2.5 Mass Concentration Using an Electrostatic Particle Concentrator-Based Quartz Crystal Microbalance

open access: yesIEEE Access, 2019
Particulate matter (PM) is one of the most critical air pollutants, and various instruments have been developed to measure PM mass concentration. Of these, quartz crystal microbalance (QCM) based instruments have received much attention.

The influence of temperature, humidity, and simulated sunlight on the infectivity of SARS-CoV-2 in aerosols

open access: yesAerosol Science and Technology, 2020
Recent evidence suggests that respiratory aerosols may play a role in the spread of SARS-CoV-2 during the ongoing COVID-19 pandemic. Our laboratory has previously demonstrated that simulated sunlight inactivated SARS-CoV-2 in aerosols and on surfaces. In

Small uncrewed aircraft based microphysical measurements of polar stratus cloud during the Pallas Cloud Experiment 2022 [PDF]

open access: yesEarth System Science Data
A dataset of in situ observations of stratus cloud microphysics was created from measurements performed at the Pallas atmosphere-ecosystem super site during the Pallas Cloud Experiment (PaCE) in autumn 2022. The data were collected using a small uncrewed

Speciation of Magnesium in Aerosols Using X-ray Absorption Near-Edge Structure Related to Its Contribution to Neutralization Reactions in the Atmosphere

open access: yes, 2021
Aerosols, including mineral dust, are transported from China and Mongolia to Japan, particularly in spring. It has been recognized that calcium (Ca) carbonate is the main Ca species in aerosols, which reacts with acidic species such as sulfuric and ...
