There is great interest in aluminum based plasmonic devices due to the relatively high plasma frequency of this material as well as its low cost and self-passivating oxide layer. The passivation layer provides aluminum plasmonics with the long-term stability required for practical applications. While several studies have investigated the impact of this oxide layer on the plasmon resonances of a...

We present a study of the specific heat and effective thermal conductivity in anisotropic and randomly oriented multi-wall carbon nanotube (MWCNT) and randomly oriented single-wall carbon nanotube (SWCNT) composites from 300 to 400 K. Measurements on randomly oriented MWCNTs and SWCNTs were made by depositing a thin film of CNTs within a calorimetric cell. Anisotropic measurements were made on ...

in this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(v/v) percent of the reports. the overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

One of the ways to waste energy in buildings is wasting it from the walls. For this reason, insulating materials are used to prevent the loss of energy in buildings. Typically, common insulations are high thickness and thin coatings are used less. The purpose of this research is to introduce nanocomposite thin polymer coatings and its effect on thermal conductivity. For achieving this, chemical...

A sonochemistry-based synthesis method was used to produce nanocrystalline nickel oxide powder with ≈ 20 nm average crystallite diameter from Ni(OH)(2) precursor. Ultrasound waves were applied to the primary solution to intensify the Ni(OH)(2) precipitation. Dried precipitates were calcined at 320°C to form nanocrystalline NiO particles. The morphology of the produced powder was characterized b...

We compared the reactivity of spherical particles composed aluminum (Al) and silicon (Si) with Al similar size (nominal diameter 1–2 ?m). Both were synthesized using a liquid atomization technique such that both encapsulated in native oxide passivation shell. Differential scanning calorimetry (DSC) thermogravimetric analysis (TGA) inert oxidative environments performed coupled X-ray Diffraction...

   Magnetic iron oxide nanoparticles have numerous applications in the biomedical field. This paper reports the preparation and properties of iron oxide nanoparticles synthesised by thermal decomposition method from iron chelates. The iron oxide nanoparticles were characterized by FTIR, powder XRD, VSM, SEM and TEM techniques. FTIR and powder XRD studies show that iron oxide was fo...

The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper...

Anodic oxide fabricated by anodizing has been widely used for nanostructural engineering, but the nanomorphology is limited to only two oxides: anodic barrier and porous oxides. Therefore, the discovery of an additional anodic oxide with a unique nanofeature would expand the applicability of anodizing. Here we demonstrate the fabrication of a third-generation anodic oxide, specifically, anodic ...

BioAggregate is a new product that was formulated for root-end filling, perforation repair, and pulp capping. This study examined the chemical differences between white mineral trioxide aggregate (MTA) and BioAggregate in both powder and set forms using X-ray diffraction. The results showed that white MTA and BioAggregate have a similar chemical composition with some differences: BioAggregate c...
