Composite elastomer microwave absorbers were developed based on two-phase hybrid filler. Nanosized magnetite was synthesized for the first time in porous texture of activated carbon. Combination fillers with high dielectric losses such as active carbon, and magnetic into filler is considered a new Hightech generation specific technical characteristics. The influence obtained shielding effective...

OBJECTIVES Bulk-fill composites have emerged, arguably, as a new "class" of resin-based composites, which are claimed to enable restoration in thick layers, up to 4mm. The objective of this work was to compare, under optimal curing conditions, the physico-mechanical properties of most currently available bulk-fill composites to those of two conventional composite materials chosen as references,...

In this work the fracture toughness of epoxy resin has been improved through the addition of low loading of single part and hybrid nanofiller materials. Functionalised multi-walled carbon nanotubes (f-MWCNTs) was used as single filler, increased the critical strain energy release rate, GIC, by 57% compared to the neat epoxy, at only 0.1 wt% filler content. Importantly, no degradation in the ten...

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 ...

Abstract Technical control of filler distribution in polymer composites has been great interest because the structural modulation embedded assembly leads to superior property enhancement with reduced amounts filler. However, sophisticated technologies fillers, including alignment, assembly, filler-to-filler connection and localization nanocomposites, still pose challenges. Herein, we introduce ...

Mixed matrix membrane used to selective removal of CO2 was considered as an efficient solution to energy and environmental sustainability. In this study, a MMM that consists of amide functionalized porous coordination polymer filler (MIL-53-NH2) was successfully prepared, which sharply promotes the CO2/N2 selectivity from 44 (neat polymeric membrane) to 75. Remarkably, the positive effect of am...

Abstract Epoxy resin (EP) materials are frequently used in high voltage power equipment because of their excellent electricity, force, and heat properties. However, under the condition DC voltage, surface EP insulation material is more likely to accumulate charge, which distorts nearby electric field causes flashover along surface. In this article, a nanocomposite coating was prepared by sprayi...

The use of UHMWPE has attracted the attention of many researchers and industries. The aim of the present work is to fabricate UHMWPE/MoS2-Oxide nano-composites using in-situ polymerization. For this purpose, modified molybdenum disulfide was used. In order to perform the polymerization, a Ziegler-Natta catalytic system, with MoS2-Oxide and magnesium Ethoxide as support, was used. In order to fa...

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...
