Excitation using femtosecond laser pulses induced ultrafast heating of discontinuous gold nanowires, resulting in transient thermal expansion of the gold nanostructures that constitute the nanowires. The cross-plasmon resulting from the closely arranged gold nanostructures along the nanowires was modified by the change in the small gaps due to the thermal effect. This led to the spectral shift ...

The construction of a donor–acceptor Stenhouse adduct molecular layer on gold surface is presented. To avoid the incompatibility thiol surface-binding group with polyene structure switch, an interfacial reaction approach was followed. Poly(dopamine)-supported nanoparticles quartz slides were chosen as substrates, which expected to facilitate both and switching process by providing favorable ste...

We propose a technique to measure the opening time for micromachined switches and present substantial experimental data for switches with gold–gold contacts. The data demonstrate that contact opening time increases dramatically as apparent contact area increases or as pull-apart force or contact resistance decreases. A model of opening time is also presented with model parameters that fit the e...

The effect of enhancement the hydrophobic properties ensemble micro- and nanostructures ZnO as a result coating with gold was discovered. For first time, it has been shown that nanoparticle layer leads to sharp increase in wetting edge angle from 145 168 ° (water drop volume 5 mm3) decrease hydrophobicity/hydrophilicity transition time under ultraviolet irradiation. Keywords: ZnO, gold, superhy...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

In this paper we propose a novel method of realizing discrete-time (D-T) signal amplification using NanoElectro-Mechanical (NEMS) devices. The amplifier uses mechanical devices instead of traditional solid-state circuits. The proposed NEMS-based D-T amplifier provides high gain and operate on a wide dynamic range of signals, consuming only a few micro watts of power. The proposed concept is sub...

This paper describes the significance of iterative approach and structure damping analysis which help to get better performance validation shunt capacitive RF MEMS switch. The micro-cantilever based electrostatic ally actuated switch is designed after multiple iterations on cantilever a modification obtained that requires low actuation voltage 7.3 V for 3 ?m deformation. To validate we have per...

Lithography can be performed with beams of neutral atoms in metastable excited states to pattern self-assembled monolayers (SAMs) of alkanethiolates on gold. An estimated exposure of a SAM of dodecanethiolate (DDT) to 15 to 20 metastable argon atoms per DDT molecule damaged the SAM sufficiently to allow penetration of an aqueous solution of ferricyanide to the surface of the gold. This solution...

Solving the atomic structure of metallic clusters is fundamental to understanding their optical, electronic, and chemical properties. Herein we present the structure of the largest aqueous gold cluster, Au146(p-MBA)57 (p-MBA: para-mercaptobenzoic acid), solved by electron micro-diffraction (MicroED) to subatomic resolution (0.85 Å) and by X-ray diffraction at atomic resolution (1.3 Å). The 146 ...
