“…The success of this methodology has increased the scope of ball milling to the controlled synthesis of NPs. [66][67][68] Fig. 1 (bottom region) illustrates this method, where the NPs are produced by the reduction of precursor compounds generating the growth species (metal atoms).…”

Mechanicalg rinding/milling can be regarded as historically the first technology for changing the properties of matter.M echanicallya ctivated molecular units (mechanophores) can be present in various structures:p olymers,m acromolecules, or smallm olecules. However,o nly polymers have been reported to effectively transduce energy to mechanophores,w hich induces breakage of covalentb onds. In this paper,asecond possibility is presented-molecular capsules as stress-sensitiveu nits. Mechanochemical encapsulation of fullerenes in cystine-based covalent capsules indi-cates that complexation takes place in the solid state, despite the fact that the capsules do not possess large enough entrance portals. By using as et of solvent-free MALDI (sf-MALDI) and solid-state NMR (ss-NMR) experiments,i th as been provent hat encapsulation proceedsduring milling and in this process hydrazones and disulfides get activated for breakage, exchange, and re-forming. The capsules are porousa nd therefore prone to collapse under solvent-free conditions and their conformational rigidity promotes the collapse by the breaking of covalent bonds.[a] Dr.

“…This approach comprises the reduction or decomposition of salt precursors, the generation of the growth species, and their nucleation and growth to produce the final NPs. [16] Qualitative investigations have demonstrated the capacity of ball milling to generate NPs and nanoclusters. [10][11][12][17][18][19][20][21] The targeted control over NP size and shape, however, remains challenging and poorly understood.…”

<div>The development of time-resolved in situ approaches for monitoring mechanochemical</div><div>transformations has revolutionized the field of mechanochemistry. Currently, the established in</div><div>situ approaches greatly limit the scope of investigations that are possible. Here we develop a new</div><div>approach to simultaneously follow the evolution of bulk atomic and electronic structure during a</div><div>mechanochemical synthesis. This is achieved by coupling two complementary synchrotron-based</div><div>X-ray methods: X-ray absorption spectroscopy and X-ray diffraction. We apply this method to</div><div>investigate the bottom-up mechanosynthesis of technologically important Au nanoparticles in the</div><div>presence of three different reducing agents. Moreover, we demonstrate how X-ray absorption</div><div>spectroscopy offers unprecedented insight into the early stage generation of growth species (e.g.</div><div>monomers and clusters), which lead to the subsequent formation of nanoparticles. These</div><div>processes are beyond the detection capabilities of diffraction methods. The approach is general,</div><div>and not limited to monitoring NP mechanosynthesis. This combined X-ray approach paves the</div><div>way to new directions in mechanochemical research of advanced electronic materials.</div>
