This paper describes the synthesis of low dimensional structures of copper by electrodeposition method using polycarbonate track etch membrane (PCTEM) as template. Copper microwires of different diameters were fabricated by using the membranes of pore diameters 0.2 & 0.4 um as template. The morphology of fabricated microwires was characterized by scanning electron microscope and material confir...

purpose: to compare the complications of pegging between the polycarbonate peg system and the titanium peg system. method: complications associated with pegging (polycarbonate: bio-eye or titanium: dr-perry new p-k) were reviewed from the hospital records of 153 patients over 5 years. results: out of 153 cases, 96 (62.3%) were male and 57 (37.7%) were female. mean age was 27.7 yr (6-59 yr). in ...

The effect of pore morphology on fluid flow through track-etched polycarbonate membrane was studied numerically by using the fluid flow software FLUENT. The model of membrane structure is a 3D bi-periodic porous surface with circular holes of finite thickness. Both of the effects of constriction and expansion of inner pore geometries on fluid flow are taken into consideration in numerical calcu...

One-dimensional (1D) nanoparticle chains with defined nanojunctions are of strong interest due to their plasmonic and electronic properties. A strategy is presented for the assembly of 1D gold-nanoparticle chains with fixed and rigid cucurbit[n]uril-nanojunctions of 9 Å. The process is electrokinetically accomplished using a nanoporous polycarbonate membrane and controlled by the applied voltag...

One-dimensional iron metallic nanotubes were prepared by electroless deposition within the pores of polycarbonate (PC) membranes. The longitudinal nucleation of the nanotubes along the pore walls was achieved by mounting the PC membrane between two halves of a U-shaped reaction tube. Palladium nanoparticles were post-deposited on the inner wall of the nanotubes. The composition, morphology, and...

A technique was developed to study microcolony formation by silicone-immobilized bacteria on polycarbonate membrane filters under anaerobic conditions. A sudden shift to anaerobiosis was obtained by submerging the filters in medium which was depleted for oxygen by a pure culture of bacteria. The technique was used to demonstrate that preinduction of nitrate reductase under low-oxygen conditions...

We have realised a microsystem for the culture and electrical characterisation of epithelial cell layers for cell-based diagnostic applications. The main goal of this work is to achieve both cell culture and impedimetric and potentiometric characterisation on a single device. The miniaturised cell culture system enables the uses of scarce epithelial cells, as obtained from transgenic mice or fr...

Four techniques for the detection and quantification of Dirofilaria immitis microfilariae in peripheral blood were compared, namely the conventional thick smear, thick films prepared by cytocentrifugation, filtration of blood through polycarbonate membranes, and density gradient centrifugation followed by membrane filtration. The efficiency of the methods and their sensitivity was assessed by d...

This work reports for the first time possibility of green synthesis and antibacterial effect silver nanoparticles (AgNPs) on commercialized polycarbonate membrane. The AgNPs were loaded membrane serving as substrate via ultra-sonication centrifugation. extracts from red flowers Callistemon viminalis used chelating agent. synthesised thin film characterized by various techniques such Scanning El...
