Abstract The highly variable spatial composition of desert soils remains a major source of uncertainty in estimates of dust radiative forcing. Existing soil mineralogy data sets used in climate models are limited by sparse ground observations and coarse spatial resolution.

Studies of kaolinite surfaces are of industrial importance. One useful method for studying the changes in kaolinite surface properties is to apply chemometric analyses to the kaolinite surface infrared spectra.

Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Clay-associated organic matter in kaolinitic and smectitic soils
The primary source of soil organic matter is plant debris of all kinds, such as dead roots, leaves and branches that enter into the soil and are then biologically decomposed at variable rates.

Work‐Related Asthma From Exposure to Cardboard and Paper Products
ABSTRACT Background We assess the contribution of cardboard dust exposure to the development of work‐related asthma (WRA). Prior studies on paper‐dust‐related breathing problems have focused on exposures in the paper milling and pulp industries. There have been no reports of asthma linked to workplace exposure to cardboard dust.

THE EFFECT OF KAOLINITE ON CALCIUM CARBONATE WATER-BASED DRILLING FLUID
This study evaluates the effect of kaolinite addition on calcium carbonate water-based drilling fluids (WBM) through systematic laboratory testing. Kaolinite was incorporated at concentrations of 42.8 kg/m³ (15 lb/bbl), 85.6 kg/m³ (30 lb/bbl), and 128.4 ...

Water Cationic Composition on Potassium Displacement in Tropical Soils
ABSTRACT This study aimed to evaluate the interplay between water hardness, sodium adsorption ratio (SAR), and electrical conductivity (EC); with tropical soil physical, chemical, and mineralogical characteristics on the displacement K+. The water quality treatments represented solutions suitable and not suitable for irrigation, with varying levels of ...

New insights into the molecular structure of kaolinite–methanol intercalation complexes
A series of kaolinite–methanol complexes with different basal spacings were synthesized using guest displacement reactions of the intercalation precursors kaolinite–N-methyformamide (Kaol–NMF), kaolinite–urea (Kaol–U), or kaolinite–dimethylsulfoxide ...
