We used density functional theory (DFT) calculations to investigate the physical origin of mechano-chemical response materials interfaces. Our results show that can be decomposed into contribution from interface itself (deformation interfacial bonds) and a underlying solid. The relative contributions depend on stiffness these regions contact geometry, which affects stress distribution within bu...

The purpose of this research is to study the effect methods preliminary preparation thermally activated clay, which a pozzolanic component in water-resistant composite gypsum binders, as well mechanochemical activation joint grinding clay with addition plasticizer on activity and change required number composition binders. It was found that amount gypsum-cement-pozzolan when ground specific sur...

In this work, “lead free” 0.99K0.5Na0.5NbO3-0.01BiFeO3 (KNN–BF) piezoceramics were prepared by a combination of mechanochemical activation, Spark Plasma Sintering and post-annealing treatment. Results show that the annealing treatment causes important microstructural electrical changes. The SPS sample was characterized low resistance, while air annealed samples showed better insulating properti...

a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...

The bulk solvent-free synthesis of cyclopropanes via a ball-milling-enabled Simmons–Smith reaction is herein described.

Kaolinite contains the largest amount of aluminosilicate, has a high surface area and volume ratio, is closely connected with tetrahedral Si2O5 octahedral AI2(OH)4 sheets, thus forms two-sheet phyllosilicate structure. It belongs to 1:1 type clay structural classification. also an important commonly used mineral. In this study, mineral properties Khongor-Ovoo kaolinite, located in Khar-Airag su...

Abstract Mineral carbonation is a potentially attractive sequestration technology for the permanent safe disposal and immobilization of CO 2 . In this technology, chemically reacted with calcium, sodium, magnesium containing materials to form thermodynamically stable environmentally harmless minerals, usually carbonates. our research, mechanical activation red mud was carried out in order enhan...
