Caprolactam modified casein(CA-CPL) was prepared by using casein and caprolactam firstly. Caprolactam modified casein/waterborne polyurethane composite (CA-CPL/WPU) was prepared from CA-CPL and WPU. E...
Reading the second edition of Moore and Reynolds°OX-ray Dif- fraction and the Identification and Analysis of Clay Minerals is an absolute delight. It is rare to come away from reading a scientific ...
2H NMR spectra of synthetic deuterated kaolinite have been collected in the temperature range from 150 K to 350 K. Hydroxyl groups show a Pake doublet pattern with an asymmetry factor of 0. They are a...
The electrostatic lattice energy of polar phyllosilicates can be calculated when a correction term Ecorr equal to −2鸬2/V is taken into account, where ?is the dipole moment of a slice d(001) and ...
The hydroxyl orientations in the 2H2 polytype of amesite, Mg2Al(SiAl)O5(OH)4, have been determine by minimizing the electrostatic potential energy as a function of OH orientation. The angles, ρ, betwe...
Hydroxyl orientation has a major influence on the strength of the ionic interlayer bonding in micas because of the strong repulsion between the hydrogen and the interlayer cation (IC). In order to det...
The possibility of recording the absorption band which is related to oscillations of free OH in a superficial plane of the octahedral sheet of kaolinite inspired the present authors to review the prob...
On NH4- as well as on (C2H5)3NH-montmorillonite EDA was adsorbed in protonated form. The extent of protonation depended on the relative basicities and concentrations of the interacting compounds. In t...
Ethylenediamine (EDA) adsorbed from aqueous solution or vapor phase on Al-, Ca- and Mg-montmorillonite was retained to a more or less large extent in protonated form. The NH3+ :NH2 ratio decreased wit...
Abstract: Ethylenediamine (EDA) is adsorbed from aqueous solution on Na-, K- and Li-montmorillonite as the monoprotonated cation (EDAH+) through an ion-exchange process. On washing with distilled wate...
A simple electrostatic model has been used to demonstrate that the inner surface hydroxyls in kaolinite, dickite and nacrite are responsible for the interlayer bonding in these minerals. The contribut...
The form under which ethylenediamine (EDA) is adsorbed from aqueous solution by hydrogen- and ethylenediammonium-montmorillonite was studied as a function of the amount of amine present in the system....
