15 μm thick polycarbonate films were irradiated with Ni ions (11.64 MeV/n) having fluence of the order of 106 ions/cm2. Irradiated foils were etched chemically in 6N NaOH solution at 50°C for 12 minutes to obtain the cylindrical pores having average diameter of 100 nm. Cylindrical pores in these membranes have been used as templates for the synthesis of copper nanowires. A two-electrode electrochemical cell was used for copper electrodeposition in porous polycarbonate templates from acidic copper sulphate solution at 29 ± 1°C. The morphology of copper nanowires were studied by means of scanning electron microscopy (SEM). Effects of microwave treatment on these nanowires were also studied. [ABSTRACT FROM AUTHOR]

Reports an indirect method for estimating qualitative change in the resistivity of thermally annealed silver microstructures. Irradiation of polycarbonate samples; Etching in electrolytically controlled etching cell; Emission wavelengths for unannealed microstructures; Emission wavelengths upon annealing.

The article informs that the electrodeposition has been widely used to fabricate nano-structures in the nanochannels of templates. The ion track etched membranes are ideal templates to prepare nano-structures of desired shapes because of defined pore shapes and size under different etching conditions. The silver sulfide, has relatively high absorption coefficient. The compounds of silver sulfide's group have a wide variety of potential applications such as infrared detectors and photosensitive films in optoelectronic devices, principal elements in thermo power cells and solar selective coatings. The conical nano-structures of silver sulfide have been fabricated by electrodeposition.

This article presents information on chemical synthesis of polypyrrole nano/microstructures using track etch membranes. Among the different strategies to synthesize nanoscopic materials reported in the literature, template synthesis is an elegant approach. This technique consists of including metallic or organic constituents inside the void spaces of nanoporous host materials. In the present work, the chemical growth of polypyrrole nanofibrils obtained from polycarbonate nanoporous particle track-etched membranes is studied. The morphologies of the obtained microstructures have been carefully analyzed using a scanning electron microscope. A two-probe method has been used to measure the electrical conductivity of template-synthesized polypyrrole microstructures.

The article presents information related to the galvanic-fabrication of CdS microstructures using nuclear track filter membranes (NTF). Ordered or regimented arrays of nanostructures are potential vehicles for implementing a large number of high performance electronic, magnetic, optical, and multifunctional devices and sensors. Most of the semiconductors being synthesized chemically belong to the group II-VI, IV-V and III-V binary systems as well as ternary diluted magnetic semiconductor clusters. CdS, one of the well-known photonic materials, has been synthesized as clusters by adopting mimic organic polymerization reactions as synthesis strategy. NTFs have been put to numerous filtration applications besides their use in the synthesis of nano/microstructures and devices.

This article focuses on microstructure fabrication. It is not only of immense importance for microelectronics technology but also plays a vital role as a potent tool for carrying out investigations relating to behavior of materials at sub micron scales. In the recent years, it has broadened to encompass more and more areas of multidiscipline. A variety of possible applications include high power microwave generation, ultra fast computer and tetra hertz amplifier devices fabrication, radiation and temperature insensitive electronics.
