in this study, the removal of cadmium and lead ions from aqueous solution by nanocrystalline magnetite was investigated. the nanocrystalline magnetite was synthesized by mechanochemical activation of hematite in a high energy planetary mill in argon atmosphere for 45 hours. the ability of the synthesized nanocrystalline magnetite for removal of cd(ii) and pb(ii) from aqueous solutions was studi...

Mechanochemical interaction of tungsten with gallium was studied. Using x-ray diffraction and electron microscopy, it shown that after mechanical activation a W-Ga mixture for 1 min, is completely spread, as thin layer, onto the surface, while longer leads to formation W(Ga) solid solution. Moreover, be incorporated into lattice only if grains reach certain critical nanosize.

The swelling force exerted by solvents in polymer gels is revealed to trigger mechanochemical reactions, as reported Takuma Watabe and Hideyuki Otsuka their Research Article (e202216469). A multinetwork strategy based on sequential monomer polymerization processes makes the original network sensitive mechanical stimuli. slight volume expansion caused leads activation of mechanoresponsive linker...

Abstract Mechanochemical reactions of the GaN-Al 2 O 3 interface offer a novel principle for scientific and technological merits in micro-/nano-scale ultra-precision surface machining. In this work, mechanochemical on Ga- N-faced GaN surfaces rubbed by Al nanoasperity as function environmental humidity were investigated. Experimental results indicate that N-face exhibits much stronger removal o...

Cobalt ferrite (CoFe2O4) nanoparticles were synthesized and investigated as a catalyst in the reaction of nitrous oxide (N2O) decomposition. was by solid–phase interaction at 1100 °C preliminary mechanochemical activation roller-ring vibrating mill 400 °C. The characterized X-ray diffraction (XRD), synchronous thermal analysis (TG DSC) scanning electron microscopy (SEM). A low-temperature nitro...

Covalent polymer mechanochemistry offers promising opportunities for the control and engineering of reactivity. To date, covalent mechanochemistry has largely been limited to individual reactions, but it also presents potential for intricate reaction systems and feedback loops. Here we report a molecular architecture, in which a cyclobutane mechanophore functions as a gate to regulate the activ...

NiFe2O4 (nickel ferrite), ZnFe2O4 (zinc ferrite) and Ni0.5Zn0.5Fe2O4 (nickel-zinc ferrite) were prepared by mechanochemical route in a planetary ball mill starting from mixture of the appropriate quantities of the Ni(OH)2/Fe(OH)3, Zn(OH)2/Fe(OH)3 and Ni(OH)2/Zn(OH)2/Fe(OH)3 hydroxide powders. In order to monitor the progress of chemical reaction and confirm phase formation, powder samples obtai...
