enhanced electroanalytical sensitivity via interface miniaturisation ion transfer voltammetry at an array of nanometre liquid liquid interfaces
Electroanalysis, 2011Co-Authors: Micheal D Scanlon, Damien W M ArriganAbstract:The benefit of Miniaturization towards the nanoscale of electroanalytical systems was evaluated by assessment of the sensitivity of the response. Ion transfer voltammetry across the interface between two immiscible electrolyte solutions (ITIES) was employed as the basis for detection of nonredoxactive ions. The analytical sensitivity increased on miniaturisation of the interface from millimetre-, to micrometre-, to nanometre-scale, with an improvement in sensitivity of more than three orders of magnitude. This is due to the enhanced mass transport via convergent diffusion as the size of the ITIES is minimised. These results illustrate the benefit of miniaturisation of electrochemical detection methods to the nanoscale.

a topology based Miniaturization of circularly polarized patch antennas
IEEE Transactions on Antennas and Propagation, 2013Co-Authors: K SarabandiAbstract:A novel approach for the Miniaturization of circularly polarized patch antennas is presented. This enables a size reduction of as high as 75%, compared to a conventional corner-truncated circularly polarized patch antenna. The proposed design procedure consists of a number of intermediate steps, each of which produces antenna Miniaturization as well as the desired polarization and impedance matching properties. This is very challenging in miniaturizing circularly polarized probe-fed patch antennas. It is shown that two resonant frequencies can be tuned independently to produce a dual band antenna with two orthogonal polarizations. Finally, two circularly polarized miniaturized patch antennas with different Miniaturization factors are fabricated, and their input impedances, radiation patterns and axial ratios are discussed.

Miniaturization in biocatalysis
International Journal of Molecular Sciences, 2010Co-Authors: Pedro FernandesAbstract:The use of biocatalysts for the production of both consumer goods and building blocks for chemical synthesis is consistently gaining relevance. A significant contribution for recent advances towards further implementation of enzymes and whole cells is related to the developments in miniature reactor technology and insights into flow behavior. Due to the high level of parallelization and reduced requirements of chemicals, intensive screening of biocatalysts and process variables has become more feasible and reproducibility of the bioconversion processes has been substantially improved. The present work aims to provide an overview of the applications of miniaturized reactors in bioconversion processes, considering multi-well plates and microfluidic devices, update information on the engineering characterization of the hardware used, and present perspective developments in this area of research.

Miniaturization of microstrip antennas by the novel application of the giuseppe peano fractal geometries
IEEE Transactions on Antennas and Propagation, 2012Co-Authors: Homayoon Oraizi, Shahram HedayatiAbstract:We investigate the possibilities and properties of the application of Giuseppe Peano fractal geometry for the Miniaturization of microstrip patch antennas and compare its performance with those of the usual fractals, such as Koch, Tee-Type and Sierpinski. The length of the Giuseppe Peano fractal patch perimeter increases, while its surface area remains constant without any more space occupation. Consequently the antenna Miniaturization, maintenance of its gain and increase of its relative frequency bandwidth are achieved. The proposed antenna has circular polarization at one of its resonance frequencies, which is realized by producing a perturbation on its initial structure. Further Miniaturization of antenna may be obtained by cutting slots on its structure and its broadbanding may be achieved by placing an air gap under its metallic patch and more effective Miniaturization is obtained by placing a Giuseppe Peano fractal strip along the microstrip patch antenna.
