Light absorbing particles (LAP, eg, black carbon, brown carbon, and dust) influence water
and energy budgets of the atmosphere and snowpack in multiple ways. In addition to their …

Elemental-, equivalent black-and refractory black-carbon are terms that have been defined
in order to dissect the more general term, black carbon, into its component parts related to its …

Black carbon aerosol plays a unique and important role in Earth's climate system. Black
carbon is a type of carbonaceous material with a unique combination of physical properties …

Although the definition and measurement techniques for atmospheric" black carbon"(" BC")
or" elemental carbon''(" EC") have long been subjects of scientific controversy, the recent …

Thermal-optical analysis is a conventional method for determining the carbonaceous
aerosol fraction and for classifying it into organic carbon, OC, and elemental carbon, EC …

Charring of organic carbon (OC) during thermal/optical analysis is monitored by the change
in a laser signal either reflected from or transmitted through a filter punch. Elemental carbon …

This study investigates the aqueous stability of multi-walled carbon nanotubes (MWNTs) in
the presence of natural organic matter (NOM). MWNTs were readily dispersed as an …

The US Environmental Protection Agency (EPA) initiated the national PM2. 5 Chemical

Soot, which is produced from biomass burning and the incomplete combustion of fossil and
biomass fuels, has been linked to regional and global climate change and to negative health …

Measurements of black carbon (BC) concentration have long been uncertain. Neither a BC
standard or a technique that provides a reliable measurement of BC exist, which precludes …
