Mechanochemical Transformations of Biomass into Functional Materials
ChemSusChem, 2022AbstractBiomass is one of the promising alternatives to petroleum‐derived materials and plays a major role in our fight against climate change by providing renewable sources of chemicals and materials. Owing to its chemical and structural complexity, the transformation of biomass into value‐added products requires a profound understanding of its ...

Kinetics of mechanochemical transformations
Physical Chemistry Chemical Physics, 2020To help understanding the mechanisms underlying mechanochemical transformations, we propose a kinetic model that relates macroscopic and microscopic scales while accounting for the statistical nature of the mechanical processing of powder.

Mechanochemical synthesis of alumina nanoparticles: Formation mechanism and phase transformation
Powder Technology, 2012 Nanosized alumina powders were synthesized by mechanochemical treatment of stoichiometric mixture of anhydrous AlCl3 and CaO. X-ray powder diffraction (XRD), differential thermal and thermogravimetric analysis (DSC-TG), Fourier transform infrared ...

Reaction Coordinates and Pathways of Mechanochemical Transformations
The Journal of Physical Chemistry B, 2015The notions of a reaction path and a reaction coordinate are central to chemistry as they provide low-dimensional descriptions of complex molecular processes. Here we discuss how to define, compute, and use the reaction paths for chemical transformations in molecules that are subjected to mechanical stress and thus driven toward regions of ...

Mechanochemical transformation of haematite to magnetite
Nanostructured Materials, 1995Abstract The transformation of α-Fe 2 O 3 to Fe 3 O 4 on wet-milling α-Fe 2 O 3 under low energy conditions in vacuum has been investigated by Mossbauer effect spectroscopy. The structural transformation is discrete with no evidence of interdissolution of the 2 phases.

Mechanochemical Radical Transformations in Organic Synthesis
Chemistry – A European JournalAbstract Organic synthesis has historically relied on solution‐phase, polar transformations to forge new bonds. However, this paradigm is evolving, propelled by the rapid evolution of radical chemistry. Additionally, organic synthesis is witnessing a simultaneous resurgence in mechanochemistry, the formation of new bonds in the solid ...
