Preface

“…In this context, O'Quinn and coworkers apply in our next paper a very powerful analytical method (High-resolution Neutron Total Scattering experiments with Pair Distribution Function (PDF) analysis), to compare short-versus long-range structural features of a multicomponent oxide, pyrochlore-type Er 2 Ti 2 O 7 , obtained by two different powder processing methods: conventional solid-state reaction at high temperature and mechanical milling [7]. Our next group of papers deals with mechanochemical effects in the synthesis, structure and properties of a wide variety of inorganic systems including metal alloys [8][9][10][11][12][13][14], oxides [15][16][17][18] and composites [19][20][21]; these studies include for example using cryomilling (milling attrition of powders with a cryogenic medium) to obtain nanocrystalline highentropy alloys [8], a shaker mill to produce nonequilibrium alloys in immiscible systems at room temperature [9], obtaining nanoparticulated LiFeM 2-O 6 (M = Ge, Ti) pyroxenes [18] and assessing the reactivity of highly exothermic metal oxide thermitetype composites subjected to mechanical activation [20], to mention some. Another group of papers studies the synthesis and properties of lanthanidedoped silicon nitride nanowires [22], Ti and Hf carbides [23], Ni boride [24], Zr boride ceramics [25] and Cu-and Sn-based sulfides [26,27].…”
