“…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 ].…”

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.

The effect of nitrogen gas flow rate on heat treatment of AISI Abstract. In this research, the deposition of (Fe-Cr)-50at.% Al coatings on low carbon steel was carried out by a mechanical alloying (MA) technique. The MA was performed in a shaker mill for 4 hours. Two types of Fe-Cr powders as starting material were used, high purity Fe-Cr powders: (Fe-12.5Cr)-50Al and (Fe-25Cr)-50Al, and Fe-Cr lump powder: (50FeCr)-50Al (in at.%). The coated samples were then annealed in a vacuum furnace at 700 o C for 1h. The characterizations of coating structure before and after annealing were studied by XRD and SEM-EDX, while the coating hardness was measured by micro-Vickers hardness tester. Before annealing, all of coating composition were composed mainly of (Fe,Cr)Al phase. After annealing, the FeAl and Fe0.99Cr0.02Al0.99 intermetallic phases was formed in the (Fe-12.5Cr)-50Al and (Fe-25Cr)-50Al coatings. In addition, Fe2CrAlwas also found in the (Fe-25Cr)-50Al coating. Whilethe AlCr2 intermetallic phase was detected as the main phase of (50FeCr)-50Al coating. The cross-sectional microstructure showed that the (Fe-12.5Cr)-50Al and (Fe-25Cr)-50Al coatings have a smoother structure compared to (50FeCr)-50Al coating. The annealing led to intermetallic phase formation and an increasing coating hardness.

Chemical vapor deposition (CVD) diamond film has high heat resistance, high thermal stability, and other excellent properties as nature single-crystalline diamond. The surface polishing, large size planarization, and high material removal rate of CVD diamond film are limited due to its special crystal structure and excellent physicochemical characteristics. Dynamic friction polishing (DFP) technology is a new and effective polishing method of diamond. In this paper, according to the theory of graphitization of diamond catalyzed by unpaired d electrons, two manganese-based alloys, Mn-Cu and Mn-Ni, are selected as polishing materials to achieve high quality and high efficiency polishing of diamond and verify the mechanism of DFP. Alloying polishing plates were prepared by mechanical alloying method and spark plasma sintering technology. The polishing results of Mn-Cu and Mn-Ni alloys were compared and analyzed through DFP experiments. The experimental results showed that since Mn-Ni alloy has more unpaired d electrons than Mn-Cu alloy, Mn-Ni alloy was more likely to form vacant rails and showed a higher material removal rate of CVD diamond film. The addition of Cu decreased the wear of polishing plate with the help of its lubrication action.
