“…This hypothesis is supported by findings recently published for Zn nanofibers prepared by evaporation of Zn powder. [37] The TEM image ( Figure 3 d) also shows the presence of agglomerated particles with lower contrast. EDX measurements on these agglomerated particles indicate a 1:1 atomic ratio of zinc and oxygen.…”

“…To the best of our knowledge there is as yet no report on the formation of "Zn whiskers" at such a low temperature. [37] It can be suggested that the Zn whiskers grow by a vapor-solid (VS) mechanism caused by the high volatility of elemental zinc. This hypothesis is supported by findings recently published for Zn nanofibers prepared by evaporation of Zn powder.…”

ZnO can be regarded as one of the most important metal oxide semiconductors for future applications. Similar to silicon in microelectronics, it is not only important to obtain nanoscale building blocks of ZnO, but also extraordinary purity has to be ensured. A new gas-phase approach to obtain size-selected, nanocrystalline ZnO particles is presented. The tetrameric alkyl-alkoxy zinc compound [CH 3 ZnOCH(CH 3 ) 2 ] 4 is chemically transformed into ZnO, and the mechanism of gas-phase transformation is studied in detail. Furthermore, the morphological genesis of particles via gas-phase sintering is investigated, and for the first time a detailed model of the gas-phase sintering processes of ZnO is presented. Various analytical techniques (powder XRD, TEM/energy-dispersive X-ray spectroscopy, magic-angle spinning NMR spectroscopy, FTIR spectroscopy, etc.) are used to investigate the structure and purity of the samples. In particular, the defect structure of the ZnO was studied by photoluminescence spectroscopy.

“…Furthermore, since there is no catalyst particle at the tips of the nanowires, these Zn nanowires should be formed via a vapor-solid (VS) mechanism [31]. It is clear that the ball milling treatment of the starting materials enhances the nanowire formation in both density and quantity, which could be associated with a faster reaction between B and ZnO, as well as a reduced reaction temperature.…”

One-dimensional (1D) nanomaterials including nanotubes, nanowires and nanorods have many new properties, functionalities and a large range of promising applications. A major challenge for these future industrial applications is the large-quantity production. We report that the ball milling and annealing process has the potential to achieve the mass production. Several examples including C, BN nanotubes and SiC, Zn nanowires are presented to demonstrate such capability. In addition, both size and structure of 1D nanomaterials can be controlled by varying processing conditions. New growth mechanisms involved in the process have been investigated and the highenergy ball milling has an important role in the formation of these 1D nanomaterials. r

“…Of the various physical and chemical methods, radiation chemistry, laser ablation technique [11], thermal evaporation [12][13][14], biosynthesis [15,16], and electrodeposition [17][18][19][20][21] are often used to synthesise zinc nanostructures. Of all the methodologies developed for the preparation of Zn NPs, the electrochemical method (bottom-up approach) offers a simple alternative mean for high yield of nanoparticles.…”

Nanocrystalline zinc was electrodeposited by reducing the Zn 2? ion from acid sulphate bath at room temperature. The effect of reaction parameters on the particle size, nature and spectral characteristics are deliberated. The surface morphology and texture of zinc nanoparticles (Zn NPs) were characterised by high resolution scanning electron microscopy (HR-SEM) and high resolution transmission electron microscopy (HR-TEM). SEM and TEM images showed the Zn NPs were in hexagonal structural morphology. Energy dispersive X-ray analysis reveals the chemical stoichiometry, and purity of the particles formed. The powder X-ray diffraction data indicates that the reflections of Zn NPs correspond hexagonal close packing structure with space group of P63/mmc. The line broadening was analysed by Debye-Scherrer equation and the average crystallite size of the zinc Nps synthesised at room temperature was in the range of 29 nm. WilliamsonHall analysis was used to study the contribution of crystallite size and lattice strain on the peak broadening. The surface plasmon resonance peak for the Zn NPs was observed near the blue shift with optical band gap of 3.38 eV. The influences of the current density, pH, additives, and concentration medium were analysed.
