CO2 Hydrogenation Induced by Mechanochemical Activation of Olivine With Water Under CO2 Atmosphere

open access: yesFrontiers in Energy Research, 2019
A study on the mechanochemical activation of the olivine in presence of H2O and under CO2 atmosphere have been approached, focusing both on the structural nature of the transformation and the conversion of CO2 to methane and light hydrocarbons.

Solvent-Free Mechanochemical Synthesis of ZnO Nanoparticles by High-Energy Ball Milling of ε-Zn(OH)2 Crystals

open access: yesNanomaterials, 2021
A detailed investigation is presented for the solvent-free mechanochemical synthesis of zinc oxide nanoparticles from ε-Zn(OH)2 crystals by high-energy ball milling. Only a few works have ever explored the dry synthetic route from ε-Zn(OH)2 to ZnO.

Cooperation of dual modes of cell motility promotes epithelial stress relaxation to accelerate wound healing. [PDF]

open access: yesPLoS Computational Biology, 2018
Collective cell migration in cohesive units is vital for tissue morphogenesis, wound repair, and immune response. While the fundamental driving forces for collective cell motion stem from contractile and protrusive activities of individual cells, it ...

Pasteur made simple – mechanochemical transformation of racemic amino acid crystals into racemic conglomerate crystals

open access: yes, 2020
Conglomerate crystallization is required for many deracemization or enantioenrichment protocols. Here, we report the metal-mediated mechanochemical transformation of racemic compounds of some proteinogenic amino acids – valine, leucine and isoleucine ...

The formation kinetic of mechanochemical synthesized perovskites [PDF]

open access: yes, 2021
In this study, we aimed to achieve mechanochemical perovskite synthesis and to quantify the energy used during milling (Eb - impact energy and Ecum - cumulative energy) and to describe the relationship between them.
