Adsorption Characteristics of Bixin on Acid- and Alkali-Treated Kaolinite in Aprotic Solvents

Bioinorganic Chemistry and Applications, 2018
The adsorption of bixin in aprotic solvents onto acid- and alkali-treated kaolinite was investigated. Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FT-IR, EDS, and BET-N2.

Influence of Kaolinite Clay Supplementation on Growth Performance and Digestive Function in Finishing Calf-fed Holstein Steers [PDF]

Asian-Australasian Journal of Animal Sciences, 2016
Two experiments were conducted to examine the influence of kaolinite clay supplementation (0%, 1%, or 2% diet dry matter [DM] basis) on characteristics of digestion (Trial 1) and growth performance (Trial 2) in calf-fed Holstein steers fed a finishing ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Molecular dynamics study on the effect of minerals on the mechanical heterogeneity of anthracite coal：A case study of kaolinite in the southern part of the Qinshui Basin

Meitan xuebao
Coal is a mixture of organic macerals and minerals. The presence of minerals can lead to differences in the macromolecular structure of coal, resulting in significant heterogeneity in its mechanical properties, which in turn affects the overall coalbed ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Effects of bleaching and functionalization of kaolinite on the mechanical and thermal properties of polyamide 6 nanocomposites

RSC Advances, 2020
Polyamide 6 nanocomposites (PA6)/kaolinite were prepared by melt compounding. First, kaolinite was bleached via a solvothermal reaction using oxalic acid as a bleaching agent; then, the bleached product was modified using dimethylsulfoxide (DMSO) and ...

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.
