Carbon hydrogasification is the slowest reaction among all carbon-involved small-molecule transformations. Here, we demonstrate a mechanochemical method that results in both faster rate and new synthesis route. The was dramatically enhanced by up to 4 orders of magnitude compared traditional thermal method. Simultaneously, exhibited very high selectivity (99.8 % CH4, versus 80 under conditions)...

Mechanochemical activation and steam-assisted interzeolite transformation offer a simple, fast cost-efficient synthesis route to gmelinite (GME) zeolite. The use of faujasite (FAU) as the parent zeolite precursor facilitates reaction results in high yields high-quality GME less than 20 h under optimized conditions. accessible porosity amounts stacking-faults were determined by N2 physisorption ...

With the current increase of interest in amorphous MOFs and ZIFs for various applications, there is a need optimal environmentally friendly synthesis parent materials. One that has received most research to date, along with ZIF-62, ZIF-76. ZIF-62 already been produced mechanochemically, while majority ZIF-76 currently using solvothermal an autoclave DMF as solvent. Herein, we present two new gr...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...

Type II restriction endonucleases protect bacteria against phage infections by cleaving recognition sites on foreign double-stranded DNA (dsDNA) with extraordinary specificity. This capability arises primarily from large conformational changes in enzyme and/or DNA upon target sequence recognition. In order to elucidate the connection between the mechanics and the chemistry of DNA recognition an...

A new mechanism for fast reaction of Al nanoparticles covered by a thin oxide shell during fast heating is proposed and justified theoretically and experimentally. For nanoparticles, the melting of Al occurs before oxide fracture. The volume change due to melting induces pressures of 1–2 GPa and causes dynamic spallation of the shell. The unbalanced pressure between the Al core and the exposed ...

A recently suggested melt-dispersion mechanism (MDM) for fast reaction of aluminium (Al) nano- and a few micrometre-scale particles during fast heating is reviewed. Volume expansion of 6% during Al melting produces pressure of several GPa in a core and tensile hoop stresses of 10 GPa in an oxide shell. Such stresses cause dynamic fracture and spallation of the shell. After spallation, an unload...

Highly conductive, transparent, flexible and scalable graphene hybrid thin films with controlled domain size were successfully fabricated via a mechanochemical method, screen printing and pressure-assisted reduction process.

Strong and stable under tension? In this review we present the recent efforts investigating the mechanochemical properties of interlocked structures by atomic force microscopy and polymer mechanochemistry.

In this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. An impression of grinding time on the structural and thermal properties of Sr-doped LaMnO3 system with La1-xSrxMnO3 (x=0.2) stoichiometric ratio was investigated.
