On the additivity of the properties of humic acid fractions

open access: yes, 2010
The structure and origin of properties of humic acids (HA) are still a matter of great concern. To enter into the structure of HA, a fractionation procedure was carried on, that combines both size cut-off membrane and pH grade fractionation on a XAD-8 ...

Polypropylene Nonwoven Fabric Filters Containing Graphene Oxide: A Streamlined Approach to Enhance Ultrafine Particulate Matter Removal

open access: yesPolymer Engineering &Science, EarlyView.
A simple graphene oxide coating strategy enhanced the ultrafine particulate matter (PM0.1) filtration performance of polypropylene nonwoven filters. The oxygen‐containing functional groups of graphene oxide improved particle capture while preserving low pressure drop and high air permeability.
