“…[1][2][3][4] Although patterned nanowires and devices can be fabricated by conventional ultraviolet, e-beam, nanoimprint or other lithography technologies taking advantages of the precision and repeatability of the top-down fabrication, 5 it is becoming obvious that both physical and economic factors of current lithography technologies will limit further advances of the integrated circuit industry. Besides the top-down approaches, nanowires are commonly grown by the bottom-up approaches such as solution growth, vapor-liquidsolid method, and electrochemical deposition into nanoporous templates at a relatively low cost.…”

“…In the past decade, a wide range of nanowire-based devices such as field effect transistors, single virus detectors, photo-detectors, and chemical/biological sensors have been demonstrated to show superior performance than their thin-film counterparts. [1][2][3][4][5][6] Nevertheless, scalable and controlled assembly of nanowires on a variety of rigid or flexible substrates still presents a major challenge toward their potential integration for electronic circuitry, because most of the nanowire devices are limited to the demonstration of single devices, not adequate for production on a large scale at low cost.…”

Semiconducting inorganic nanowires (NWs), nanotubes and nanofibers have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics, chemical/biological/ optical sensing, and energy harvesting, storage and conversion, etc. Besides the top-down approaches such as conventional lithography technologies, nanowires are commonly grown by the bottom-up approaches such as solution growth, template-guided synthesis, and vapor-liquid-solid process at a relatively low cost. Superior performance has been demonstrated using nanowires devices. However, most of the nanowire devices are limited to the demonstration of single devices, an initial step toward nanoelectronic circuits, not adequate for production on a large scale at low cost. Controlled and uniform assembly of nanowires with high scalability is still one of the major bottleneck challenges towards the materials and device integration for electronics. In this review, we aim to present recent progress toward nanowire device assembly technologies, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic-field-directed assembly, contact/roll printing, planar growth, bridging method, and electrospinning, etc. And their applications in high-performance, flexible electronics, sensors, photovoltaics, bioelectronic interfaces and nano-resonators are also presented.

“…10,11 Due to the excellent thermal conduction behavior of CNTs, they are also used to enhance the thermal conductivity of polymeric composites not only for improving thermal conductivity but also electric conductivity and mechanical properties. 12,13 CNTs have a unique one-dimensional structure that enables the composites filled with CNTs to have low percolation threshold concentrations. 14,15 Due to these characteristics, composites filled with CNTs show the enhancement of thermal conductivity even at low concentrations.…”

In order to enhance the thermal conductivity of poly(dimethyl siloxane) (PDMS), boron nitride (BN) and carbon nanotubes (CNTs) were incorporated as the thermally conductive fillers. The amount of BN was increased from 0 to 100 phr (parts per hundred rubber) and the amount of CNTs was increased from 0 to 4 phr at a fixed amount of the boron nitride (100 phr). The thermal conductivity of the composites increased with an increasing concentration of BN, but the incorporation of CNTs had only a slight effect on the enhancement of thermal conductivity. Unexpectedly, the thermal degradation of the composites was accelerated by the addition of CNTs in 100 phr BN filled PDMS. Activation energy for thermal decomposition of the composites was calculated using the Horowitz-Metzger method. The curing behavior, electrical resistivity, and mechanical properties of PDMS filled with BN and CNTs were investigated.

Graphene-based nanomaterials have shown great promise not only in nanoelectronics due to ultrahigh electron mobility but also as biocatalytic scaffolds owing to irreversible protein surface adsorption and facilitating direct electron transfer. In this work, we synthesized stable dispersions of graphene using liquid-phase exfoliation approach based on non-covalent interactions between graphene and 1-pyrenesulfonic acid sodium salt (Py–1SO3), 1-pyrenemethylamine salt (Py − Me-NH2) and Pluronic® P-123 surfactant using only water as solvent compatible with biomolecules. The resulting graphene nanoplatelets (Gr_LPE) are characterized by a combination of analytical (microscopy and spectroscopy) techniques revealing mono- to few-layer graphene displaying that the exfoliation efficiency strongly depends upon the type of pyrene-based salts and organic surfactants. Moreover being completely water-based approach, we build robust nanoscaffolds of graphene-family nanomaterials (GFNs) namely, monolayer graphene, Gr_LPE (the one prepared with Pluronic® P-123), graphene oxide (GO) and its reduced form (rGO) on glassy carbon electrode surface with three important metalloproteins include cytochrome c (Cyt c) [for electron transfer], myoglobin (Mb) [for oxygen storage] and horseradish peroxidase (HRP) [for catalyzing the biochemical reaction]. In order to demonstrate the nanobiocatalytical activity of these proteins, we used electrochemical interfacial direct electron transfer (DET) kinetics and attempt to determine the rate constant (kET) using two different analytical approaches namely, linear sweep voltammetry and Laviron’s theory. We elucidated that all of the metalloproteins retain their structural integrity (secondary structure) upon forming mixtures with GFNs confirmed through optical and vibrational spectroscopy and biological activity using electrochemistry. Among the GFNs studied, Gr-LPE, GO and rGO support the efficient electrical wiring of the redox centers (with an increase in catalytic efficiency of Cyt c and Mb in the presence of GFNs attributed partially to the surface functional (carboxyl, epoxide and hydroxyl) groups on GO and rGO facilitating rapid charge transfer.
