“…In their method, thiol end groups were produced chemically on the SWNT ends and defects, and then by surface acoustic waves to a SWNT suspension, the SWNT were oriented with respect to the electrodes. [44] Thus, the AuNPs were tethered to the thiolated SWNTs. The SWNTs and AuNPs were characterized by SEM images.…”

“…[60] The driving force for the self-assembly was the formation of a surface-combined pseudorotaxane (Scheme 3). The stable dispersion of dodecanethiol-modified AuNPs was prepared by the method described by Brust et al [44] The nearly size-monodisperse fraction was subsequently modified by the exchange of the adsorbed thiol for thiol-incorporating crown molecules (dodecanethiol incorporating a crown moiety in the terminal position). [61] The MWNTs were modified by two amide-coupling reactions: the first was between the carboxy-modified MWNTs and ethylenediamine, and the second between the remaining amine of the coupled ethylenediamine and the cation precursor [N-(4-carboxydibenzylamine)carbamate].…”

Carbon nanotubes constitute a novel class of nanomaterials with potential applications in many areas. The attachment of metal nanoparticles to carbon nanotubes is new way to obtain novel hybrid materials with interesting properties for various applications such as catalysts and gas sensors as well as electronic and magnetic devices. Their unique properties such as excellent electronic properties, a good chemical stability, and a large surface area make carbon nanotubes very useful as a support for gold nanoparticles in many potential applications, ranging from advanced catalytic systems through very sensitive electrochemical sensors and biosensors to highly efficient fuel cells. Here we give an overview on the recent progress in this area by exploring the various synthesis approaches and types of assemblies, in which nanotubes can be decorated with gold nanoparticles and explore the diverse applications of the resulting composites.

The paper numerically studies the contribution of the electric field accompanying the surface acoustic wave to the actuation of the acoustic streaming in microchannels. The finite element method is used. The results obtained as applied to the surface waves on 128° and 64°-rotated Y cuts of LiNbO3 demonstrate that the force created by the electric field is capable of accelerating appreciably the acoustic streaming. In particular, examples are given for the situations where the electric field increases the streaming velocity by a factor of about 2–3 and significantly changes the flow pattern as compared to predictions of computations ignoring the electric field.

“…11,12 It was found that the velocity of propagation of the domain walls depends on the amplitude of the SAW. In the area of microfluidics, recent research demonstrates that SAWs provide an effective means to manipulate fluids (fluid mixing, [13][14][15] translation, [16][17][18] jetting, 19 and atomization 20 ) and manipulate particles (handling, 21 focusing, 22 separation, 23,24 sorting, 25,26 concentration, [27][28][29][30] and reorientation 31 ) in lab-on-a-chip devices for applications in chemistry, biology, and medicine. The ability for a SAW to mix, translate, jet, and atomize droplets is dictated by its amplitude.…”

Vector network analyzer measurement of the amplitude of an electrically excited surface acoustic wave and validation by X-ray diffraction Surface acoustic waves are used in magnetism to initiate magnetization switching, in microfluidics to control fluids and particles in lab-on-a-chip devices, and in quantum systems like two-dimensional electron gases, quantum dots, photonic cavities, and single carrier transport systems. For all these applications, an easy tool is highly needed to measure precisely the acoustic wave amplitude in order to understand the underlying physics and/or to optimize the device used to generate the acoustic waves. We present here a method to determine experimentally the amplitude of surface acoustic waves propagating on Gallium Arsenide generated by an interdigitated transducer. It relies on Vector Network Analyzer measurements of S parameters and modeling using the Coupling-Of-Modes theory. The displacements obtained are in excellent agreement with those measured by a very different method based on X-ray diffraction measurements. Published by AIP Publishing.
