Scope The use of mechanical energy to stimulate physical and chemical processes in the solid state has been intensively studied. However, the recent availability of new, and more powerful milling devices, abrasion-resistant milling tools, and the advances gained in understanding the fundamentals of mechanochemical processes, have opened a whole new world of opportunities and triggered renewed interest in the subject. Currently, mechanical milling is applied in materials science for the synthesis of almost any type of substance, including inorganic, organic, and organometallic compounds, nanostructures and composites, and for the preparation of alloys and intermetallics. Mechanical activation is also used in conjunction with mineral processing, and solid state processing technologies as well as to increase the reactivity of energetic materials. Several novel phases, and new phenomena has been discovered. The fourth edition of this Symposium in the MS&T Conferences, seeks to reinforce its role as a premier interdisciplinary forum for researchers and practitioners to exchange ideas, and share experiences and recent results in all aspects of mechanochemical reactions, from fundamentals to methods, materials, applications, opportunities, and challenges.
The scientific program will consist of keynote and invited lectures from renowned experts in the field, oral presentations and posters. The symposium will cover, but is not limited to, the following topics:
Thermodynamics, kinetics and modeling of mechanochemical processes (e.g., fundamentals and models, mass and energy transfer, and phase changes).
Solid state synthesis, and processing (e.g., mechanochemistry, mechanical alloying, mechanical activation, combustion synthesis of activated precursors, reaction milling, cryomilling, liquid- and electric discharge-assisted milling).
Atomic and electronic structures, and structural analysis (e.g., formation and recovery of mechanically induced defects, non-equilibrium structures, amorphization, the role of point defects, grain boundaries and dislocations).
Properties and (micro)structure-property relationships of mechanochemically prepared materials (e.g., chemical, electrical, magnetic, thermal and mechanical).
New materials and composites obtained using mechanochemical methods (e.g., amorphous alloys, quasicrystalline phases, cocrystals, nanomaterials, and nanocomposites).
Applications (e.g., gas-solid reactions, catalysis, hydrides, organics and organometallics, mineral processing, extractive metallurgy and waste treatment, cement and glass manufacturing).
Recent developments in instrumentation and techniques (e.g., equipment for large scale production and with improved milling dynamics)

Attendees will have the opportunity to move the field forward through collaborative efforts.
