Clay-based nanostructured multilayers, such as clay-polymer multilayers and clay-oxide multilayers, have attracted growing attention owing to their remarkable mechanical properties and promising application in various fields. In this paper, synthesis of a new kind of nanostructured clay-oxide multilayers by layer-by-layer self-assembly was explored. Nano-mechanical characterization of 18 clay-b...

Composites based on high density polyethylene (HDPE), pine flour, and organic clay were made by melt compounding and then injection molding. The influence of clay on crystallization behavior, mechanical properties, water absorption, and thermal stability of HDPE/pine composites were investigated. The HDPE/pine composites containing exfoliated clay were made by a two-step melt compounding proced...

INTRODUCTION Clays, and more specifically 2 :1 phyllosilicates consisting of aluminoor magnesiosilicate negatively charged staked layers separated by van der Walls spacings where inorganic countercations (sodium, calcium,... cations) are located, can be associated with polymers to give interesting new materials called polymer/clay nanocomposites. Polymer/clay nanocomposites have been intensivel...

The present paper should be considered as a review of the application of Fourier Transform Infra-Red for surface clay characterization. The application of surface clay materials for water treatment, oil adsorption, excipients or as active in drugs has largely increased these recent years. The surface clay material presents hydroxyl groups, which can link very easily water molecules. These hydro...

To control the molecular organization of octadecyl rhodamine B (RhB18), hybrid Langmuir–Blodgett monolayers containing clay minerals were prepared. The orientation and conformation of the RhB18 molecule were analyzed by polarized attenuated total reflection Fourier transform infrared (ATR–FTIR) spectroscopy and fluorescence spectroscopy. Monomers and dimers of RhB18 were observed by UV-Vis abso...

Detailed geological mapping contributed towards the tectonic framework of the Kala Chitta Range for the purpose of a compressive knowledge of the mode of occurrence of the Fire Clay horizons in the Datta Formation .Furthermore, detailed analytical work was carried out to elucidate the mineralogy of the Fire Clays. Lithological details and the depositional style have been highlighted comparative...

Arsenic (As) contaminated aquifers contain iron minerals and clays that strongly bind As at their surfaces. It was suggested that As mobilization is driven by natural organic matter (including fulvic acids (FA) and humic acids (HA)) present in the aquifers either via providing reducing equivalents for reductive dissolution of Fe(III) (hydr)oxides or via competitive desorption of As from the min...

Studies on recycled materials emerged during recent years. This paper investigates samples’ sound absorption properties for panels fabricated of a mixture sludge (PS) and clay mixture. PS was the core material. The measured. We also consider influence an air gap between rigid backing. Different gaps (50, 100, 150, 200 mm) simulate existing acoustic panel systems. Finally, composite coefficients...

We report on the synthesis, microstructure and mass transport properties of a colloidal hydrogel self-assembled from a mixture of colloidal silica and nontronite clay plates at different particle concentrations. The gel-structure had uniaxial long-range anisotropy caused by alignment of the clay particles in a strong external magnetic field. After gelation the colloidal silica covered the clay ...

The aim of this study is to convert mixed plastic waste into usable liquid fuel via pyrolysis technique using Ukpor clay as a low-cost catalyst and commercial grade kaolin. Waste was catalytically degraded in laboratory scale semi-batch reactor at temperature 400 °C, residence time 45 min, heating rate 16 ˚C/min. catalysts were characterized by XRF analysis while proximate the feed carried out ...
