“…The environmental aspects of these processes are particularly attractive [24,25,26]. Several chalcogenide/ZnS nanocrystals obtained by mechanochemical synthesis by our research group was published in several papers [27,28,29,30,31,32]. Regarding to the topic of this paper–preparation of CuInS 2 /ZnS, the core-shell structures or QDs have been predominantly prepared previously e.g.…”

In this study, CuInS2/ZnS nanocrystals were synthesized by a two-step mechanochemical synthesis for the first time. In the first step, tetragonal CuInS2 was prepared from copper, indium and sulphur precursors. The obtained CuInS2 was further co-milled with zinc acetate dihydrate and sodium sulphide nonahydrate as precursors for cubic ZnS. Structural characterization of the CuInS2/ZnS nanocrystals was performed by X-ray diffraction analysis, Raman spectroscopy and transmission electron microscopy. Specific surface area of the product (86 m2/g) was measured by low-temperature nitrogen adsorption method and zeta potential of the particles dispersed in water was calculated from measurements of their electrophoretic mobility. Optical properties of the nanocrystals were determined using photoluminescence emission spectroscopy.

“…The micro-Raman and micro-photoluminescence spectra with the calculated quantum yield of ZnS nanocrystals were published in our previous paper [25]. The Raman spectrum of ZnS showed one intensive peak, centered at 346 cm −1 , and a weak peak, centered at 690 cm −1 , associated with the first-order longitudinal optimal photon (1LO) and second (2LO) vibrational mode of ZnS, respectively.…”

The ZnS nanocrystals were prepared in chitosan solution (0.1 wt.%) using a wet ultra-fine milling. The obtained suspension was stable and reached high value of zeta potential (+57 mV). The changes in FTIR spectrum confirmed the successful surface coating of ZnS nanoparticles by chitosan. The prepared ZnS nanocrystals possessed interesting optical properties verified in vitro. Four cancer cells were selected (CaCo-2, HCT116, HeLa, and MCF-7), and after their treatment with the nanosuspension, the distribution of ZnS in the cells was studied using a fluorescence microscope. The particles were clearly seen; they passed through the cell membrane and accumulated in cytosol. The biological activity of the cells was not influenced by nanoparticles, they did not cause cell death, and only the granularity of cells was increased as a consequence of cellular uptake. These results confirm the potential of ZnS nanocrystals using in bio-imaging applications.

“…Other, more recent examples include the formation of silver amalgam by trituration of AgCl with HgCl 2 [ 107 ], and numerous examples of large-scale processing of slightly soluble inorganic minerals [ 108 ]. Mechanochemistry and milling are used in the synthesis of a wide range of inorganic materials, as in oxide, sulfide, carbide, nitride or boride formation [ 109 , 110 , 111 , 112 , 113 ], and are central to mechanical alloying [ 114 , 115 ]. Milling and grinding appear to have been adopted as synthetic techniques first by organic chemists, including Wöhler in the 19th century [ 116 ] and a number of solid-state organic chemistry research groups in the 20th century, notably Paul and Curtin [ 117 ], and Etter [ 118 , 119 ].…”

Advances in Solid-State Transformations of Coordination Bonds: From the Ball Mill to the Aging Chamber

2017

Controlling the formation of coordination bonds is pivotal to the development of a plethora of functional metal-organic materials, ranging from coordination polymers, metal-organic frameworks (MOFs) to metallodrugs. The interest in and commercialization of such materials has created a need for more efficient, environmentally-friendly routes for making coordination bonds. Solid-state coordination chemistry is a versatile greener alternative to conventional synthesis, offering quantitative yields, enhanced stoichiometric and topological selectivity, access to a wider range of precursors, as well as to molecules and materials not readily accessible in solution or solvothermally. With a focus on mechanochemical, thermochemical and “accelerated aging” approaches to coordination polymers, including pharmaceutically-relevant materials and microporous MOFs, this review highlights the recent advances in solid-state coordination chemistry and techniques for understanding the underlying reaction mechanisms.
