INTRODUCTION The aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (NZOE) sealer in comparison with Pulp Canal Sealer (ZOE based) and AH-26 (epoxy resin sealer). METHODS AND MATERIALS A total of 27 Wistar rats were used. Four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

Motivated by recent work on nano tubes indicating one dimensional quantum effects and studies of two dimensional electron gas, we consider a recent model of Fermions as Kerr-Newman type black holes with quantum mechanical effects. Such an anyonic fractionally charged quasi-electron picture is deduced and identified with quarks. Very recently experiments with nano tubes reveal one dimensional Qu...

The study investigated the thermal performance of a photovoltaic (PVT) collector with twisted absorber tube and nanoparticle-enhanced phase change material (nano-PCM). PVT consisted tubes, container filled nano-PCM, (PV) panel. To assess its efficiency, five different configurations were tested using an indoor solar simulator. analyzed as follows: (a) unenhanced PV panel, (b) circular tubes (C-...

As we continue miniaturization of circuits into nano-scale, interconnects have been recognized as the limiting factor for next generation of computing structures. To increase the density of integration many approaches have been proposed such as System on Chip (SoC), System in Package (SIP), and Networks on Chip (NoC)which all must address the interconnect issue address. Current approaches to So...

Hospital-acquired infections remain a costly clinical problem. Barium sulfate (BaSO4, in micron particulate form) is a common radiopacifying agent that is added to catheters and endotracheal tubes. Due to the recently observed ability of nanostructured surface features to decrease functions of bacteria without the aid of antibiotics, the objective of this in vitro study was to incorporate nano-...

Sulfur Nanoparticles was prepared by different method with different size and shapes, when the sulfur present as nanoparticles they have many practical application in our life. This paper discuses different sulfur nanoparticles synthesis, characterizations and application. Different methods were used for nanosize particle synthesis; among those, chemical precipitation, electrochemical method, m...
