The acidity of surface groups of dioctahedral smectites

open access: greenClay Minerals, 2011
AbstractSuspensions of thirty six bentonites were equilibrated for 24 h and then adjusted to pH 3. After an hour, pH titrations up to pH 12 at varying ionic strengths were performed within 4.5 h. The titration data were recalculated into proton affinity distributions (PAD) using the condensed approximation.

Vanadium occupation and its leachability differences in trioctahedral and dioctahedral mica. [PDF]

open access: yesRSC Adv, 2019
Vanadium in black shale prefers to locate in the octahedron of mica and can be more easily released from trioctahedral mica than dioctahedral mica.

Dioctahedral mixed K-Na-micas and paragonite in diagenetic to low-temperature metamorphic terrains: bulk rock chemical, thermodynamic and textural constraints [PDF]

open access: bronze, 2008
Metamorphic mineral assemblages in low-temperature metaclastic rocks often contain paragonite and/or its precursor metastable phase (mixed K-Na-white mica).

Anti-Diarrheal Effects of a Combination of Korean Traditional Herbal Extracts and Dioctahedral Smectite on Piglet Diarrhea Caused by Escherichia coli and Salmonella typhimurium [PDF]

open access: greenPakistan Veterinary Journal, 2011
The present study evaluated anti-diarrheal effects of a mixture of Coptidis rhizoma, Lonicerae flos, and Paeonia japonica (1:1:1, v/v/v) methanol extracts and dioctahedral smectite (CLPD) on piglet diarrhea caused by Escherichia coli (E.

USAGE OF DIOCTAHEDRAL SMECTITE IN CHILDREN WITH ATOPIC DERMATITIS

open access: greenВопросы современной педиатрии, 2008
The results of enter sorbent — dioctahedral Smectite (Neosmektin) — usage as part of complex therapy of children with atopic dermatitis (ATD). It is shown that the administration of Smectite favored better efficacy of baseline treatment of ATD, more express and quick regression of skin manifestations of the disease, decrease in number of children with ...

Clays for Low-Carbon Cements: Overview, Progress, and Challenges. [PDF]

open access: yesGlob Chall
This review provides a critical overview of recent developments of activated clays to function as artificial pozzolans. After a thorough description of the clays that yield good pozzolanic performances, selected examples are given on thermal and mechanical activations. Chiefly, general correlations are extracted from reported data despite its scattered

Effect of reactant ratio and nanofillers type on the microstructural properties, porosity fluctuations and heavy metal removal ability of chitosan-clay hybrid materials

open access: yesApplied Surface Science Advances, 2023
The structure, porosity, and functionality of synthesized chitosan-clay nanocomposites (NCs) are examined throughout this work in relation to the initial stoichiometry and octahedral cavity occupation of the clay fraction.

Synthesis and structure of macrocyclic dinickel(II) complex with 5-(4-pyridyl)tetrazolate as coligand

open access: yesЖурнал Белорусского государственного университета: Химия, 2021
The dinuclear nickel(II) complex [Ni2LmClO4] + , where Lm represents a 24-membered macrocyclic hexaaza-dithiophenolate ligand, reacts with 5-(4-pyridyl)tetrazole (PyrCN4H) to give the dinuclear complex [Ni2Lm(PyrCN4)]+ . The new complex was both isolated
