Clay minerals in South Australian Holocene basaltic volcanogenic soils and implications for halloysite genesis and structure

, 2014
The clay mineralogical composition was determined of 8 soils formed from pyroclastic ejecta (tephra) from adjacent 5000-year old basaltic volcanoes at Mounts Gambier and Schank in South Australia.

Delamination of kaolinite - potassium acetate intercalates by ball-milling

, 2010
Structural changes in intercalated kaolinite after wet ball-milling were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), specific surface area (SSA) and Fourier Transform Infrared spectroscopy (FTIR).

Intercalation of dodecylamine into kaolinite and its layering structure investigated by molecular dynamics simulation

, 2014
Dodecylamine was successfully intercalated into the layer space of kaolinite by utilizing the methanol treated kaolinite–dimethyl sulfoxide (DMSO) intercalation complex as an intermediate.

Nitrogen Losses, Trade‐Offs, and Mitigation Potential in Global Sugarcane Cropping Systems

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Data compiled from global sugarcane experiments are used to derive region‐specific emission factors (EFs) for multiple nitrogen (N) loss pathways and to identify the key biophysical and management drivers of N losses, crop yield, and their trade‐offs.

A DRIFT spectroscopic study of potassium acetate intercalated mechanochemically activated kaolinite

, 2003
Kaolinite has been mechanochemically activated by dry grinding for periods of time up to 10 h. The kaolinite was then intercalated with potassium acetate and the changes in the structure followed by DRIFT spectroscopy. Intercalation of the kaolinite with

Synthesis and characterization of kaolinite coated with copper oxide and its effect on the removal of aqueous Lead(II) ions

Applied Water Science, 2019
The removal of Lead (Pb2+) ions from waste water in the aquatic environment by copper oxide–kaolinite composite forms an important step involved in the reduction of Lead ions in the environment. The study investigated the synthesis, characterization, and

The Importance of Tire Wear Particles for Atmospheric Ice Nucleation

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tire wear particles (TWPs) are prevalent microplastic particles in the atmosphere and pose significant environmental and health risks to humans. Here, we investigated the ice nucleation activity (INA) of TWPs under mixed‐phase cloud conditions (∼−20.0°C < T < −5.0°C) and its changes caused by different environmental exposures, including UV and

Intensity of African Humid Periods Estimated from Saharan Dust Fluxes.

PLoS ONE, 2017
North Africa experienced dramatic changes in hydrology and vegetation during the late Quaternary driven by insolation-induced shifts of the tropical rain belt and further modulated by millennial-scale droughts and vegetation-climate feedbacks. While most

Study on the aggregation behavior of kaolinite particles in the presence of cationic, anionic and non-ionic surfactants.

PLoS ONE, 2018
Aggregation behaviors of kaolinite particles with different surfactants were studied in this paper. Aggregation settling yield and fractal dimension analysis were used to determine the aggregation results.
