Characterization of aerosol associated with enhanced small particle number concentrations in a suburban forested environment [PDF]
, 2010 Two elevated particle number/mass growth events associated with Aitken‐mode particles were observed during a sampling campaign (13–29 September 2004) at the Duke University Free‐Air CO2 Enrichment facility, a forested field site located in suburban ...

Estimating aerosol emissions by assimilating observed aerosol optical depth in a global aerosol model [PDF]
Atmospheric Chemistry and Physics, 2012 Abstract. This study estimates the emission fluxes of a range of aerosol species and aerosol precursor at the global scale. These fluxes are estimated by assimilating daily total and fine mode aerosol optical depth (AOD) at 550 nm from the Moderate Resolution Imaging Spectroradiometer (MODIS) into a global aerosol model of intermediate complexity ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose
Advanced Materials, EarlyView.Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...
