Накратко на български
Механохимията изследва как се протичат химичните реакции между твърди вещества, например чрез смилане с добавяне на минимално количество течност. Това помага за оптимизиране на индустриалните процеси и намаляване на вредното въздействие върху околната среда.

Liquid-Assisted Grinding - from Fundaments to Applications
The action and my future plans beyond are dedicated to understanding of the processes underlying the further development of new technologies based on solid-state reactions that will help energetics and industry to prevent the imminent global environmental threats. Specifically, this research is intended to improve the established scientific collaboration between EU and Canada in the field of mechanochemistry, an emerging and increasingly important field of contemporary preparational chemistry with minimized environmental impact. From the fundamental fact that any chemical reaction requires mobility of reactant molecules to allow their collisions, it seems that regularly observed amorphous or even liquid phases play an active role at the first stages of solid-state reactions, acting as a medium that enables mobility of involved chemical species, thus providing an environment in which a chemical reaction is possible. Additionally, it is clear that solid-state chemical reactions are initiated by the contact of two substances. However, this fundamental aspect has not been dealt with in sufficient detail so far. Our experimental approach enable us to qualitatively and quantitatively detect and characterize the evolution of chemical species involved in fundamental processes under the hood of solid-state reactivity. In a specific context of green chemistry, understanding and optimization of the mechanochemical procedures, which are inherently solvent-free or use minimal, catalytic amounts of solvents, is highly beneficiary to optimization of the performance of chemical industry with minimization of its environmental impact. In perspective, this action could position both included institutions at the fore-front of clean technologies and sustainability on the global scale.

Цел на проекта
Liquid-assisted grinding (LAG) is a mechanochemical process in which a catalytic amount of added liquid tremendously accelerate the reaction kinetics, and often significantly alter reaction outcome. Due to high applicability potential of LAG and still a huge amount of ambiguities, it has become essential to improve understanding of reaction mechanisms at molecular level. Establishing a correspondence between solution and solid-state reaction mechanisms would enable utilisation of huge body of knowledge in the currently barely grazed mechanistic framework of solid-state milling reactions, which is a prerequisite for their systematic use and utilisation in Green Chemistry synthetic alternatives, which would be a critical requirement for any industrial application of LAG. This project should contribute implementation of MCh for a cleaner chemical laboratory and a sustainable, low-waste and low-emissions chemical and pharmaceutical industry. It is unacceptable that further development of such an important methodology depends on a mere trial and error or, at best, on the experimenter's experience and instincts. Here, recently developed techniques for in situ real-time monitoring of MCh reactions by X-ray diffraction and Raman spectroscopy will be employed to enable insight into uninterrupted reactions and thus resolution of mechanistic pathways and kinetics of the selected representative simple reactions. The obtained data will be interpreted with respect of properties of liquids added to LAG systems. It is expected that in this way the catalytic action of liquids in LAG reactions will be put to a firmer ground. The accumulated fundamental understanding of LAG reactions will be then applied to develop or improve Green Chemistry procedures for selected environmentally relevant processes and materials. This should consequently lead to optimisation of these processes, setting them ready for scale-up to ecologically friendlier, sustainable industrial processes.
