Grinding in some form or other has been instrumental for the development of early medical remedies, something thatweareoftenstillremindedofbythemortar-and-pestlesymbolfoundoutsideof manypharmacists’stores.Chemistryresultingfrommechanicalscratchingandmill- inghasattractedtheattentionofsomeofthelegendsofearlychemistryandphysical sciences,asseeninM.Faraday’sexplorationsofreactivityofhydratedinorganicsol- ids,orinthereporteduseofKügelchenbyWöhler.Whilechemicalreactionsinduced bymechanicalactionwereestablishedandwellrecognizedintheearly20thcentury, with the subject given the name mechanochemistry in Ostwald’s The Fundamental Principles ofChemistry, thisareasubsequently fellintodisregard and oblivion.That is, until now – modern days have seen a true renaissance of mechanical reactivity acrossprobablyallmajorareasofchemicalsynthesisandmaterialschemistry,rang- ingfromorganicsynthesistonanoparticlematerials. This exciting spirit of new exploration and recognizing new opportunities of- fered by the cleaner, safer and simply “greener” solvent-free reaction medium of mechanochemistryis perfectlycaptured by thisintroductory textbookto the topic, edited by Colacino, Ennas, Halasz, Porcheddu and Scano. These authors are, each intheirownway,pushingforwardthenewmechanochemistrywhichhasbeenun- dergoingvirtuallyexplosive,previouslyunseenlevelofdevelopment.Thisdevelop- ment has created a clear need for a broader, but still accessible, overview of the field, in the form that could be attractive, approachable and taken as an introduc- torymaterialtothewiderangeofapplicationsthatarenowbeingaddressedbyme- chanosynthesis by milling or grinding. This book covers that need in the most satisfactoryway,providinganeasytofollowoverviewofthefield,whichincludesa brief and broad discussion of the area in Chapter 1, followed by a succinct, clear and useful discussion of the available apparatus in Chapter 2, highlighting their fundamental designs, and importantly the similarities and differences, advantages anddisadvantages.Thebookalsoprovidesamoredetailedfocusonselectedareas ofmechanochemistry,someofwhicharebasedontraditionaldivisionsofreactivity ininorganicsystems(Chapter3),whileothersprovideadifferentlineofreasoning.

The authors have surmounted this challenge with outstanding success and I warmlyrecommendMechanochemistry–APracticalIntroductionFromSofttoHard Materials as an excellent introductory synthesis-by-mechanochemistry text to stu- dents,educators,afficionadosandexpertsalike.
