Novel anodic aluminium oxide (AAO) films and hollow nanostructures were synthesized via a simple electrochemical and chemical etching route; fluctuating nanotube growth inside AAO film fabricated under ultra-high voltage was considered to be the main reason for the formation of such new structures.

Using anodic aluminium oxide films as collectors, all four well known carbon forms, diamond, graphitic, fullerenic and amorphous particles, are identified inside a candle flame, suggesting a new nucleation mechanism for diamond growth and fullerene formation in a combustion synthesizing process.

AIM OF THE WORK Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. MATERIALS AND METHODS It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in Engli...

In this communication, we demonstrate the inter-conversion of crystal structure of aluminium doped zinc oxide (AZO) thin films from highly (002) plane oriented vertical growth to (103) plane oriented lateral growth by adjusting the polarity of the self-assembled monolayers (SAMs) on glass substrates at room temperature.

Electron Beam Melting (EBM R ©) is a near-net-shape additive manufacturing technology developed by Arcam AB, where Ti-6Al-4V alloy powder is commonly used to manufacture medical implants and components for the aerospace industry. Although Arcam has developed special specifications of some parameters for the powders, the powders from different manufacturers do not behave in the same way in the E...

Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...

In this study, the effect of different concentration Aluminium oxide-based nanofluid on performance Solar Desalination system was discussed. The Oxide used in concentrations 1%, 2% and 6% weight basis. flow rate also varied its efficiency compared with water there improvement occurred during variation incident radiation. With an increase oxide nanoparticles, attained. More attained at nanoparti...
