Extinction Coefficient of Gold Nanostars [PDF]
The Journal of Physical Chemistry C, 2015 Gold nanostars (NStars) are highly attractive for biological applications due to their surface chemistry, facile synthesis and optical properties. Here, we synthesize NStars in HEPES buffer at different HEPES/Au ratios, producing NStars of different sizes and shapes, and therefore varying optical properties. We measure the extinction coefficient of the

An Aerosol Extinction Coefficient Retrieval Method and Characteristics Analysis of Landscape Images [PDF]
Sensors, 2021 Images based on RGB pixel values were used to measure the extinction coefficient of aerosols suspended in an atmospheric state. The pixel values of the object-image depend on the target-object reflection ratio, reflection direction, object type ...

Analysis of extinction properties as a function of relative humidity using a κ-EC-Mie model in Nanjing [PDF]
Atmospheric Chemistry and Physics, 2017 The relationship between relative humidity (RH) and extinction properties is of widespread concern. In this study, a hygroscopic parameter (κ) and the volume fraction of elemental carbon (EC) were used to characterize the chemical characteristics of ...

Four-year long-path monitoring of ambient aerosol extinction at a central European urban site: dependence on relative humidity [PDF]
Atmospheric Chemistry and Physics, 2016 The ambient aerosol particle extinction coefficient is measured with the Spectral Aerosol Extinction Monitoring System (SÆMS) along a 2.84 km horizontal path at 30–50 m height above ground in the urban environment of Leipzig (51.3° N, 12.4° E ...
