“…[61,63] An alternative to elemental combination is to combine a binary oxide powder and a reducing agent, which can be one of the metals to be alloyed, such as the reaction of TiO 2 and Mg to form TiMg, [66] or PbO and Te to form PbTe. [67] Alternately the reducing agent may not be intended for inclusion, such as carbon, which will be removed as a vapour (CO 2 ) -an example is the synthesis of brass from CuO, ZnO and PbO in the presence of graphite.

“…It has been reported that ball milling can trigger solid-solid reactions to synthesize PbTe alloy from PbO and Te. 11 Zhang et al reported that solid-liquid reactions happened during milling of titanium in the benzene solution of pyrazine with the formation of intermediate Ti 2 N. 12 Solid-gas reactions were also investigated systematically by milling of titanium and zirconium in a nitrogen-containing atmosphere. [13][14][15] Other than these, ball milling has also been used recently to fabricate a nanostructured material that has unique properties.…”

Technological and scientific challenges coupled with environmental considerations have attracted a search for robust, green and energy-efficient synthesis and processing routes for advanced functional nanomaterials. In this article, we demonstrate a high-energy ball milling technique for large-scale synthesis of nitrogen doped carbon nanoparticles, which can be used as an electro-catalyst for oxygen reduction reactions after a structural refinement with controlled thermal annealing. The resulting carbon nanoparticles exhibited competitive catalytic activity (5.2 mA cm(-2) kinetic-limiting current density compared with 7.6 mA cm(-2) on Pt/C reference) and excellent methanol tolerance compared to a commercial Pt/C catalyst. The proposed synthesis route by ball milling and annealing is an effective process for carbon nanoparticle production and efficient nitrogen doping, providing a large-scale production method for the development of highly efficient and practical electrocatalysts.

“…The main objective of milling is the mechanical reduction of the particle size out of a solid sample by grinding with one or more inert balls rotating around a horizontal axis. One can use this solid-state powder processing route to synthesize PbTe alloy from PbO and Te [9] [13]. Other than these, ball milling has also been used recently to fabricate a nanostructured material that has unique properties.…”

Alloying of metals is known from antiquity. Alloy making i.e., homogenizing metals started in a "hit-or-miss" way. The 1 st alloy from copper (Cu) and tin (Sn) was produced around 2500 BC and from then Bronze Age began. Subsequently iron (Fe) age started after the Bronze Age. Aluminium (Al) alloying was discovered much later because pure Al could not be recovered easily even though Al is the most abundant metal in the earth's crust. Refining of Al is a very difficult job because of its strong affinity towards oxygen. To ease alloying, melting points (mp) of the individual constituents and reactivity of metal towards oxygen were the hurdles. Now understanding the thermodynamics of metal mixing has paved alloying. Periodic properties of elements concerning size, electronegativity, crystal structure, valency, lattice spacing, etc. are considered for alloying. In this feature article, more emphasis is given to Hume-Rothery rules in which the necessary parameters for alloying have been illustrated. Importantly standard electrode potential (E 0 ) values, eutectic, phase diagram, size-related strain in metals, etc. have been looked into in the present discussion. One elegant example is Sn-Pb alloy, known as soft solder. Soft solder was in use for many years to connect metals and in electric circuitry. Low melting, flowability, and conductivity of soft solder had placed Sn-Pb alloy a unique position in industries, laboratories and even in cottage industries. However, toxic Pb volatilizes during soldering and hence soft solder is banned almost in all countries. We felt the need for a viable alternative to obtain soldering material and then silver (Ag) based highly conducting, an eco-friendly alloy of Sn resulted in from a high boiling liquid. The discovery engenders not only a new conducting soldering alloy but also a new concept of melting metals together. Furthermore, new ideas of alloying have been generalized at their nanostages from a suitable high boiling solvent.
