Exploring the Sensitivity of Visibility to PM_2.5 Mass Concentration and Relative Humidity for Different Aerosol Types

Atmosphere, 2022
Fine particle (PM2.5) mass concentration and relative humidity (RH) are the primary factors influencing atmospheric visibility. There are some studies focused on the complex, nonlinear relationships among visibility, PM2.5 concentration, and RH. However,

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Particulate Matter and Nanoparticles Toxicology [PDF]

BioMed Research International, 2013
Humans have been exposed for thousands of years to particulate matter (PM) from natural and anthropogenic sources. Since the first third of the twentieth century, health problems related to dust exposure in miners have been documented [1]. Early epidemiological data have shown evidence of the relation between inhalation of PM and several lung diseases,
