Individual semiconductor nanowires (NWs) TiO2 were successfully welded together by using novel one-dimensional (1D) Au80Sn20 (mass ratio) nanosolders at the nano scale for the first time. The nanosolders were electrodeposited into nanoporous templates to form 1D structure, and their morphology, crystal structure, chemistry and elemental electronic states were systematically characterized. Individual Au80Sn20 nanowires were proved to consist of mixed crystal phases, including Au5Sn phase with trigonal structure, AuSn phase with hexagonal structure and little SnO2 phase produced by oxidation of the surface portion. Chemical analysis indicates that the composition is Au80Sn20. The testing of welding capability either in situ TEM or in situ SEM by nanomanipulators and Infiltration experiment reveal a good wet ability and diffusion ability between the Au80Sn20 nanosolder and TiO2 nanowire. It is believed that our work contribute a special nanosolders for future nanoscale welding techniques, which also make the bondings of titanium-based semiconductor oxide nanomateirals at the nanoscale a reality.

“…5 To date many different approaches have been used to control and direct self-assembly of NCs. Notable strategies include those based on prefabricated templates, 6 small-molecule 7,8 and electrostatic interactions, 9 solution-deposition methods, 10 nanowelding, 11 and bio molecular tools. [12][13][14] Each of these methods offers alternative pathways towards self-assembly and leads to a variety of structures with different sizes, shapes, and architectures.…”

The self-assembly of inorganic nanoparticles is a research area of great interest aiming at the fabrication of unique mesostructured materials with intrinsic properties. Although many assembly strategies have been reported over the years, chemically induced self-assembly remains one of the dominant approaches to achieve a high level of nanoparticle organization. In this feature article we will review the latest developments in assembly driven by the active manipulation of nanoparticle surfaces.

“…In all of these cases, the increased and often new functionality coming from the synergetic combination of parent properties allows to expand the already wide applicability of NCs [28,51,52]. HYNCs in which spherical, rod or branched sections are connected in a controlled morphology present promises for a number of potential uses ranging from nanoelectronics to biomedical, photovoltaic and catalytic applications [52][53][54]. Thus, magnet-semiconductor NCs are very interesting as dual-use biological tags offering the ability to visualize labeled cells using both magnetic resonance and fluorescence imaging techniques while external magnetic field may be employed for the directed assembly of such materials.…”

Abstract:The design of new protocols for the colloidal synthesis of complex nanocrystals (NCs) with advanced functionalities, comprising both hybrid and hollow structures, and the study of their fundamental properties is of paramount importance for the development of a new generation of nanostructured materials. The possibility of tailoring the dimensional regime of NCs, along with its composition and structure, represents a landmark achievement in the control of their unique physico-chemical properties. These properties, alongside with the ability to cheaply produce high quality NCs in fairly large amounts by wetchemistry techniques, leads to their potential applicability from materials science to nanomedicine. Within this context, this review is focused on describing a successful framework for designing synthetic strategies for the production of advanced complex NCs, integrating the development of new synthetic methods with its structural characterization, monitoring of their properties, and study of its reactivity. As a result, it is expected to provide new routes to produce robust and easy-to-process NCs in a wide range of sizes, shapes and configurations that can be explored to achieve the combination of all degrees of control, aiming to produce a complete and diverse library of material combinations that will expand its applicability in a wide diversity of fields.
