“…CuNPs of size about 20-80 nm have been formed by irradiating copper salts by gamma rays, using Poly N-vinyl pyrrolidone and Poly vinyl alcohol as capping agents (Joshi et al 1998). Nanocopper has also been produced through solid-state reactions activated by high energy ball milling (Sheibani et al 2007). Ponce and Klabunde (2005) demonstrated the metal vapor synthesis technique to produce CuNPs by various groups.…”

“…Most of the current methods used for the synthesis of nanoparticles use either toxic chemicals and/or complex processes, which require high amounts of energy (Sheibani et al 2007). The toxic chemicals serve either as reducing agents for various metal salts to their corresponding zero valent metallic nanoparticles or as stabilizing agents to prevent nanoparticles from agglomeration.…”

We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.

“…However, the activation energies and mechanisms of displacement reactions as a function of milling time need more investigation. The possibility of mechanochemical reduction of cuprite (Cu 2 O) with graphite has been already investigated [15], but the kinetics of mechanochemical reduction and thermal reduction of mechanically activated powder mixtures have not been studied thoroughly. This paper presents detailed descriptions of the effects of mechanochemical activation on the Cu 2 O reduction with graphite and production of Cu.…”

“…Nano-crystalline copper with a mean crystallite size of 27 nm was synthesized by S. Sheibani et al [86] through solid state reduction of Cu 2 O by graphite using high energy planetary ball mill. Mechanochemical reduction of Cu 2 O with graphite resulted in a continuous decrease in the Cu 2 O mean crystallite size and an increase in internal strain during initial stage of milling operation.…”

Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience. Various bottom and top down approaches have been developed so far, for the commercial production of nanomaterials. Among all top down approaches, high energy ball milling, has been widely exploited for the synthesis of various nanomaterials, nanograins, nanoalloy, nanocomposites and nano -quasicrystalline materials. Mechanical alloying techniques have been utilized to produce amorphous and nanocrystalline alloys as well as metal/non-metal nanocomposite materials by milling and post annealing, of elemental or compound powders in an inert atmosphere. Mechanical alloying is a non-equilibrium processing technique in which different elemental powders are milled in an inert atmosphere to create one mixed powder with the same composition as the constituents. In high-energy ball milling, plastic deformation, cold-welding and fracture are predominant factors, in which the deformation leads to a change in particle shape, cold-welding leads to an increase in particle size and fracture leads to decrease in particle size resulting in the formation of fine dispersed alloying particles in the grain-refined soft matrix. By utilizing mechanical milling various kind of aluminium/ nickel/ magnesium/ copper based nanoalloys, wear resistant spray coatings, oxide and carbide strengthened aluminium alloys, and many other nanocomposites have been synthesized in very high yield. The mechanical milling has been utilized for the synthesis of nanomaterials either by milling and post annealing or by mechanical activation and then applying some other process on these activated materials. This review is a systematic view of the basic concept of mechanical milling, historical view and applications of mechanical milling in the synthesis of various nanomaterials, nanosomposites, nnaocarbons and nano quasicrystalline materials.
