The mechanical, electrical, and thermal expansion properties of carbon nanotube（CNT）-based silver and silver–palladium（10：1, w/w） alloy nanocomposites are reported. To tailor the properties of silver, CNTs were incorporated into a silver matrix by a modified molecular level-mixing process. CNTs interact weakly with silver because of their non-reactive nature and lack of mutual solubility. Therefore, palladium was utilized as an alloying element to improve interfacial adhesion. Comparative microstructural characterizations and property evaluations of the nanocomposites were performed. The structural characterizations revealed that decorated type-CNTs were dispersed, embedded, and anchored into the silver matrix. The experimental results indicated that the modification of the silver and silver–palladium nanocomposite with CNT resulted in increases in the hardness and Young＇s modulus along with concomitant decreases in the electrical conductivity and the coefficient of thermal expansion（CTE）. The hardness and Young＇s modulus of the nanocomposites were increased by 30%？40% whereas the CTE was decreased to 50%-60% of the CTE of silver. The significantly improved CTE and the mechanical properties of the CNT-reinforced silver and silver–palladium nanocomposites are correlated with the intriguing properties of CNTs and with good interfacial adhesion between the CNTs and silver as a result of the fabrication process and the contact action of palladium as an alloying element.

This manuscript presents a new fourquadrant analog multiplier using a recently reported current mode active building block, namely the Fully differential second generation current conveyor(FDCCⅡ).The proposed circuit employs single FDCCⅡ and two NMOSFETs only, thus has simple architecture. It is fully-integrable as no other external passive component has been used. Non-ideal behaviour of the reported configuration has been analysed considering current and voltage tracking errors of the FDCCⅡ. Workability of the derived multiplier is verified with PSPICE(Cadence16.6) simulations using model parameter of TSMC 0.35μm CMOS process and found to be in close agreement with theoretical anticipations. The static power consumption of the circuit is 0.107 mW. The circuit works well with good linearity(nonlinearity error ≤ 0.96%) for the input voltage range of ±0.5 V for a supply voltage of ±1 V and the output is insensitive to temperature variation. Simulation results show that the –3 dB bandwidth of the proposed multiplier is 20.67 MHz and the output referred noise√is less than 9 nV/Hz at 1 kΩ load condition. MonteCarlo analysis has also been performed for the proposed configuration. The applicability of the reported multiplier as amplitude modulator, squarer, and frequency doubler are also demonstrated.

Nonlinear materials have been well established as photo refractive switching material. Important applica- tions of isotropic nonlinear materials are seen in self-focusing, defocusing phenomena, switching systems, etc. The nonlinear correction term is basically responsible for the optical switches. Mach-Zehnder inter- ferometer （MZI） is a well-known arrangement for determining the above correction term, but there are some major problems for finding out the term by MZI. We propose a new method of finding the nonlinear correction term as well as the second order nonlinear susceptibility of the materials by using a modified MZI system. This method may be used to find out the above parameters for any unknown nonlinear material.
