Effect of Hydrogen Bonding Interaction on the Properties of Caprolactam-Modified Casein/Waterborne Polyurenthane Composite
Hydrogen Bonding Interaction Modified Casein Waterborne Polyurethane (WPU)
2011/12/15
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...
Calculation of Electrostatic Interlayer Bonding Energy and Lattice Energy of Polar Phyllosilicates: Kaolinite and Chlorite
Chlorite Electrostatic energy Interlayer bonding Kaolinite Lattice energy
2012/2/6
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 ...
Hydroxyl Orientations and Interlayer Bonding in Amesite
Amesite Fluorine Hydroxyl orientation Interlayer bonding Serpentine
2012/2/8
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...
The Influence of Hydroxyl Orientation, Stacking Sequence, and Ionic Substitutions on the Interlayer Bonding of Micas
Hydroxyl Orientation Stacking Sequence Ionic Substitutions Micas
2012/2/13
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...
New Approach to the Problem of the Interlayer Bonding in Kaolinite
Interlayer Kaolinite New Approach
2012/2/13
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...
Adsorption Of Ethylenediamine (EDA) On Montmorillonite Saturated with Different Cations—V. Ammonium- and Triethylammonium-Montmorillonite: Ion-Exchange, Protonation and Hydrogen-Bonding
Triethylammonium-Montmorillonite Adsorption Ethylenediamine
2012/2/15
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...

Adsorption Ethylenediamine Montmorillonite Hydrogen-Bonding
2012/2/14
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...
Adsorption of Ethylenediamine (EDA) on Montmorillonite Saturated with Different Cations—III. Na-, K- and Li-Montmorillonite: Ion-Exchange, Protonation, Co-Ordination and Hydrogen-Bonding
Adsorption of Ethylenediamine Montmorillonite Co-Ordination Hydrogen-Bonding
2011/11/18
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...
