Mechanochemical activation as a tool of increasing catalytic activity

Catalysis Today, 2009
Abstract The role of structure–energy properties of mechanically induced defects in the crystal structure of heterogeneous catalysts is considered. The main concepts of the mechanochemical activation effect on the activity and selectivity of catalysts are discussed.

Drug mechanochemical activation

Journal of Pharmaceutical Sciences, 2009
The aim of this review is to describe the theoretical background lying behind the solid drug mechanochemical activation by cogrinding pointing out its advantages and drawbacks. A brief historical introduction precedes the discussion about the mechanisms leading to solid drug activation.

Mechanochemically Active Soft Robots

ACS Applied Materials & Interfaces, 2015
The functions of soft robotics are intimately tied to their form-channels and voids defined by an elastomeric superstructure that reversibly stores and releases mechanical energy to change shape, grip objects, and achieve complex motions. Here, we demonstrate that covalent polymer mechanochemistry provides a viable mechanism to convert the same ...

Mechanochemical Activation of Anthracene [4+4] Cycloadducts

The Journal of Physical Chemistry Letters, 2023
Controlled formation and breaking of weak chemical bonds is a versatile method for modifying the properties of materials. Anthracene [4+4] cycloadducts are a prime example that can be formed by light and opened by external forces. We address the theoretical description of mechanochemistry of these cycloadducts, where the standard constraint geometry ...

Preparation of polyboronphenylsiloxanes by mechanochemical activation

Russian Journal of General Chemistry, 2014
Linear polyboronphenylsiloxanes containing fluorine atom at silicon and acetylacetonate group at boron have been synthesized by mechanochemical activation. Mechanochemical activation of polyphenylsilsesquioxane and boron difluoride acetylacetonate taken in molar ratio 1 : 1 was shown to lead to the formation of polyboronphenylsiloxane with the given Si/
