TL;DR: In this paper, the change in solution-phase weight average molecular weight (Mw) upon sorption of bulk (rather than isolated) surface water NOM from the Suwannee River and the Great Dismal Swamp (GDS) to goethite and kaolinite at different sorption densities and at pH 4, 22°C.

TL;DR: In this article, a log-normal model for the molecular weight distribution in aquatic fulvic acids is proposed to provide a conceptual framework for studying these size effects, which is consistent with several types of molecular weight data, including the shapes of high pressure size-exclusion chromatography (HP-SEC) peaks.

TL;DR: In this article, surface characteristics and dissolution behavior of well-crystallized (KGa-1b) and poorly crystallized (kGa-2) kaolinite standards were compared.

TL;DR: In this article, a combination of atomic force microscopy, scanning election microscopy and transmission electron microscopy was used to study reactions of 0.5-500 mg/L aqueous Pb with Ca5(PO4)3OH, hydroxylapatite (HAP), at pH 6 and 22 8C.

TL;DR: In this article, the results of in situ atomic force microscopy (AFM), ex situ AFM, optical microscopy, scanning electron microscopy and energy dispersive spectroscopy were combined with previous macroscopic investigations to characterize aqueous Pb(NO 3 ) 2 reaction with hydroxylapatite (Ca 5 (PO 4 ) 3 OH) (HAP).
