This paper deals with the preparation of organoclays by intercalating poly(ethylene glycol) molecules (PEG) between Na montmorillonite (Na-MMT) layers in a clay-water suspension system. X-ray diffraction (XRD) results of ...

The organic modification of Na-montmorillonite (Na-MMT) clay by a reaction with the sodium salts of octadecanoic acid (SOD) and dodecanoic acid (SDD) was studied for the production of effectively intercalated and organophilic ...

The variations in the structure of mineral during adsorption have been examined comparing the results of X-ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetry (TG) and infrared (IR) spectroscopy ...

The adsorption of β-carotene from solution in benzene on acid-activated Canakkale montmorillonite of Turkey has been investigated. The adsorption isotherm had two steps. The first step was of the Langmuir type, and the ...

The activation energies of dehydration and combustion of organic materials in a clay sample, and of dehydration of natural and acid-activated montmorillonite have been determined using a rising temperature programme ...

Samples of the clay mineral from the Çanakkale reserve in Turkey were activated with sulphuric acid under three different sets of conditions. DTA and TG curves of both natural and activated samples were then obtained and ...

New thermal energy storage materials were developed as poly(acrylonitrile) (PAN) nanofibers with encapsulatedphase change materials (PCMs). Sixteen samples composed of PAN shells and PEG or PEGME cores, and onecontrol ...

This study concerns with interfacial in-situ encapsulation of n-hexadecane and n-octadecane cores in poly(urea-formaldehyde) shells to fabricate microcapsules, capable of absorbing and releasing high amounts of heat ...

Owing to their high heat absorption and release capacities, chemical and thermal stability, non-toxicity, two fatty acid alkyl esters (FAAEs), methyl palmitate (MP) and isopropyl palmitate (IPP), were investigated for their ...
