Biomass heavy oil is employed to partially substitute the petroleum-based asphalt due its renewability, environmentally friendly, and cost-effective advantages. However, usage weakens high-temperature performance of petroleum asphalt. Therefore, nano-ZnO was as a modifier make composite-modified improve in this paper. It prepared two steps: first, bio-asphalt by adding biomass based on certain ...

A nano-composite powder composed of silica and carbon with a unique property could be prepared from a mixture of a silicate compound and an epoxy compound, in which the silica within the nano-composite powder has a BET surface area of as high as greater than 800m2/g although the nano-composite powder has a BET surface area of less than 10m2/g. It was estimated that the silica and the carbon are...

25 ABSTRACT: In this work the synthesis of polyaniline/chitosan/functionalized singlewalled carbon nanotube nanocomposite is carried out. For this purpose, single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) Ch...

Nanoporous templates have been developed and fabricated employing technology based on heavy ion bombardment and track etching of polymer films or polymer layers deposited on substrates; an alternative and unique tool based on the adaptation of an atomic force microscopy has been also developed to elaborate nanotemplates with pores of ultra-small dimensions down to a few nanometers. Different ty...

abstract background and aim: one of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. considering the diverse composition of available ...

Currently, Malaysia has significantly increased its reputation as a country ripe for investments in the palm-based lignocellulosic biomass space. Lignocellulosic palm biomass is composed of cellulose, hemicellulose and lignin, as well as other minor components. The presence of highly cellulose content in palm biomass is potentially convert to nanocellulose, which is a promising bio-polymer that...

Nanotechnology (nano-materials and nano-process) has been developed for both industrial and medical applications. The use of nano-medicine has been used in bio-imaging and bio-sensing, drug delivery, cancer cell diagnostics and therapeutics [1,2]. Nanoparticles (NPs) can cause tumor cell death by photothermal ablation, photodynamic toxicity, mechanical damage, or increase in the localized drug ...

Photo-catalysts have many applications in different fields of industry especially in elimination of pollutants and heavy metals from wastewater. In this study first three component nano composite and two components nano composite were prepared. These composite were applied on non-woven textiles by Pad-dry method and their effect on elimination of color and heavy metals were investigated. Morpho...

Development of new generation bio-tribological, multilayer coatings opens an avenue for fabrication of future hightech functional surfaces. In the presented work, nano-composite, Cr/CrN+[Cr/ a-C:H implanted by metallic nanocrystals] multilayer coatings have been developed for surface protection of medical tools. Thin films were fabricated by a hybrid Pulsed Laser Deposition technique. Complex m...
