“…From Figure 8 it is clear that up to a sintering temperature range 100 • C, the electrical conductivity of pure silver pellet remains almost constant and increases slightly from 100 to 150 • C and then decrease beyond the 150 • C. While in CNT reinforced silver matrix nanocomposites (6 vol % and 12 vol %) the electrical conductivity increases within a temperature range of 35 -100 • C and then decreases at 150 • C. This is due to the presence of more pores in the matrix which provide easy path for the expansion even at low temperature. Coalescence of the Ag nanoparticles during the sintering process increases the density [19] and hence the conductivity of the nanocomposites. At higher temperature, the grain size starts increasing which further reduces the electrical conductivity.…”

Metal matrix nanocomposites reinforced with carbon nanotubes (CNTs) have become popular in industrial applications. Due to their excellent thermophysical and mechanical properties, CNTs are considered as attractive filler for the improvement in properties of metals. In the present work, we have synthesized noncovalently functionalized CNT reinforced nanosilver composites by using a modified molecular level mixing method. The structure and morphology of nanocomposites are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy dispersive spectroscopy. The electrical conductivity of silver-CNT nanocomposites measured by the four-point probe method is found to be more than that of the pure nanosilver. The significant improvement in electrical conductivity of Ag/CNT nanocomposites stems from homogenous and embedded distribution of CNTs in a silver matrix with intact structure resulting from noncovalent functionalization. The low temperature sintering also enhances the electrical conductivity of Ag/CNT nanocomposites.

“…Research in the field of nanotechnology has gained significant momentum as the properties demonstrated by these structures at the nanoscale level are remarkable in terms of their applicability (Duncan 2011). Silver nanoparticles have been the prime focus of the nanoparticles' research industry due to their unique thermal (Moon et al 2005), electrical (Chen et al 2009) and optical (Kelly et al 2003) properties and also because of the use of these structures in products that range from photovoltaics (Yoon et al 2010) to biological and chemical sensors (McFarland and Van Duyne 2003). Also nanosilver has been used extensively as an anti-bacterial agent in the health industry (Jain and Pradeep 2005), food storage (Costa et al 2011), textile coatings (Perelshtein et al 2008) and also for a number of environmental applications (Li et al 2008).…”

In the present paper, biosynthesis of silver nanoparticles using Zizyphus xylopyrus bark extract is reported. Z. xylopyrus bark extract is efficiently used for the biosynthesis of silver nanoparticles. UV-Visible spectroscopy showed surface plasmon resonance peaks in the range 413-420 nm confirming the formation of silver nanoparticles. Different factors affecting the synthesis of silver nanoparticles like methodology for the preparation of extract, concentration of silver nitrate solution used for biosynthesis and initial pH of the reaction mixture were studied. The extract prepared with 10 mM AgNO 3 solution by reflux extraction method at optimum initial pH of 11, resulted in higher conversion of silver ions to silver nanoparticles as compared with those prepared by open heating or ultrasonication. SEM analysis showed that the biosynthesized nanoparticles are spherical in nature and ranged from 60 to 70 nm in size. EDX suggested that the silver nanoparticles must be capped by the organic components present in the plant extract. This simple process for the biosynthesis of silver nanoparticles using aqueous extract of Z. xylopyrus is a green technology without the usage of hazardous and toxic solvents and chemicals and hence is environment friendly. The process has several advantages with reference to cost, compatibility for its application in medical and drug delivery, as well as for large-scale commercial production.

“…Moon et al investigated the thermal behavior of silver nanoparticles (size: <20 nm), and revealed that shrinkage of the silver nanoparticles occurred over the temperature range of 150-250 °C [120]. On the other hand, Auyeung et al investigated the effect of laser decal transfer to micro cantilevers, and they found that mass deduction of micro cantilevers occurs after curing at 200-400 °C [121].…”

The aim of this work was to develop a novel hybrid manufacturing method for nanoscale three-dimensional (3D) printing with multi-material capabilities. 3D structuring methods at the micro/nanoscale are major goals of various engineering fields, and much work has been carried out to improve the minimum feature size, geometrical complexity, and material selection. With the aim of nanoscale multimaterial printing, a hybrid process was reported with an integrated nanoparticle deposition system (NPDS) and focused ion beam (FIB) system; however this process has limitations in terms of surface roughness and control over the layer thickness, as well as with the process scale, and furthermore, lack of sacrificial layers.In this dissertation, a novel hybrid process is described, which combines aerodynamically focused nanoparticle (AFN) printing, micro-machining and focused ion beam (FIB) milling. AFN printing is based on NPDS, and micromachining was used for local planarization. In addition to these processes, spincoating was used to fabricate sacrificial layers. By bridging these different II micro/nanoscale processes, the resulting hybrid process can address the limitations of the individual processes.To create the hybrid process, each process was investigated to enable compatibility. With the AFN printing system, the surface morphology of a detached substrate was observed, and the bonding mechanism between the substrate and nanoparticles was investigated. A novel printing strategy was identified to reduce the scale of the process. With the micro-machining system, different tool geometries were investigated. Complex geometries inspired by conventional-scale tools were implemented on the micro-scale, and their effects were investigated. With the FIB system, material re-deposition phenomena were investigated to reduce defects that occur during ion sputtering. A novel path-generation strategy was identified and investigated for different scanning paths.Process capability is discussed using fabrication examples and functional applications. The novel hybrid process represents a significant advance in the state of the art, and enables far improved process scales or dimensional degree of freedom, without losing the advantages of broad choice of materials.3D-pinted micro bi-material cantilevers were fabricated as a thermal actuator.The mechanical and thermal properties of the structure were investigated using an in-situ measurement system, and irregular thermal phenomena were analyzed. It is expected that these in-situ measurements of the 3D printed microstructure will contribute to materials research.Various 3D structures can be fabricated using the process described here from a range of metal/ceramic inorganic materials, including polymers. In particular, it is expected that the process will contribute to the area of customized nanoscale structuring, with potential applications in medical treatments. It is also expected that this work will contribute to further improvements in manufacturing technology by combining different m...
