The aim of this work was to study the stability and morphological properties of polystyrene latex containing kaolinite as a filler during the process of synthesis of nanocomposites viaemulsion polymerization. Nanocomposites with 1, 3, and 5 wt% of kaolinite were prepared. Latexes with 1 to 3 wt% of kaolinite were stable during the polymerization reaction. Hydrodynamic diameters of 93.68 and 82.11 nm were found for latexes with 1 and 3 wt% of kaolinite, respectively. The quantities of 1 to 3 wt% of kaolinite added during the reaction did not influence the reaction conversion curves or the number of particles. X-ray diffraction (XRD) and unconventional techniques of scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) showed the presence of exfoliated and intercalated structures of the kaolinite.

Article Synopsis
  • * This research marks the first discovery of kaolinite or halloysite on another planet, alongside findings of dehydrated minerals indicating possible intense alteration processes.
  • * The rocks' formation likely resulted from intense water activity followed by heating and dehydration, possibly linked to impact events that dispersed the materials across the crater.

This work presents an interdisciplinary approach combining materials science, ultrasonication, artistic expression, and curatorial practice to develop and investigate novel composites. The focus of the approach is incorporating graphene oxide (GO) into kaolin and exploring its effects on material properties. The composites were prepared with varying GO concentrations and sonication times, and their mechanical, thermal, and morphological characteristics were evaluated.

Effect of the coconut fibers and cement on the physico-mechanical and thermal properties of adobe blocks.

Heliyon

October 2024

Laboratoire de Chimie et Energies Renouvelables (LaCER), Université Nazi BONI, Bobo Dioulasso, B.P. 1091 Bobo 01, Burkina Faso.

This work aimed to investigate the effect of cement and coconut fibers on the thermal and physico-mechanical characteristics of adobe blocks. Thus, a clayey raw material consisting of kaolinite (62 wt%), quartz (31 wt%), goethite (2 wt%) with a plasticity index of 21.5 % was used to manufacture adobe blocks amended with cement and coconut fibers.

The Early Cretaceous clay-rich facies of the Sembar Formation represent the most significantly occurring organic-rich sediments in the Southern Indus Basin of Pakistan. In this study, detailed geochemical research of total organic carbon, biomarker, mineralogy and trace elemental compositions, together with kerogen microscopic analysis, were carried out and used to understand the organic matter input and the dispositional environmental setting of the organic-rich Sembar shale. The Sembar shales have high organic matter, as indicated by the total organic carbon (TOC) content of up to 2.

The Synergistic Effect of Calcained Coal-Series Kaolinite and Limestone on the Hydration of Portland Cement.

Materials (Basel)

September 2024

Nanjing Institute of Environmental Sciences, Ministry of Ecology and Environment of the Peopole's Republic of China, Nanjing 210042, China.

Limestone calcined clay cement (LC) presents a promising alternative material due to its reduced CO emissions and superior mechanical properties compared to traditional Portland cement (PC). This study investigates the synergistic effect of calcined coal-series kaolinite (CCK) and limestone (LS) on the hydration behavior of cement, specifically focusing on varying mass ratios. The combination of CCK and LS promotes the formation of strätlingite and carboaluminates, which enhances early-age strength development.
