Curing enhancement and network effects in multi-walled carbon nanotube-filled vulcanized natural rubber: evidence for solvent sensing
(
John Wiley and Sons Ltd
, 2017 , Article)
Electrically and thermally conductive polymer composites offer great possibilities in various electronic fields because of their low weight and ease of processing. This paper addresses the curing behaviour and network ...
Microstructure and compressive behavior of Al-Y2O3 nanocomposites prepared by microwave-assisted mechanical alloying
(
MDPI AG
, 2019 , Article)
In this study, Al–Y2O3 nanocomposites were synthesized via mechanical alloying and microwave-assisted sintering. The effect of different levels of yttrium oxide on the microstructural and mechanical properties of the Al–Y2O3 ...
Enhanced photocatalytic performance of WON@porous TiO2 nanofibers towards sunlight-assisted degradation of organic contaminants
(
Royal Society of Chemistry
, 2018 , Article)
In the last few decades, TiO2 has been widely used in different types of photocatalytic applications. However, the relatively large optical band gap (∼3.2 eV), low charge carrier mobility and consequently its low quantum ...
Synthesis and Performance Evaluation of Pulse Electrodeposited Ni-AlN Nanocomposite Coatings
(
Hindawi Limited
, 2018 , Article)
This research work presents the microscopic analysis of pulse electrodeposited Ni-AlN nanocomposite coatings using SEM and AFM techniques and their performance evaluation (mechanical and electrochemical) by employing ...
Active and stable methane oxidation nano-catalyst with highly-ionized palladium species prepared by solution combustion synthesis
(
MDPI AG
, 2018 , Article)
We report on the synthesis and testing of active and stable nano-catalysts for methane oxidation. The nano-catalyst was palladium/ceria supported on alumina prepared via a one-step solution-combustion synthesis (SCS) method. ...
Erosion behavior of API X120 steel: Effect of particle speed and impact angle
(
MDPI AG
, 2018 , Article)
The dry erosion behavior of API-X120 pipeline steel was investigated, under the erosive interaction of aluminum oxide particulates, in a range of speed (43-167 m·s-1) and impact angle (30°-90°). Erosion behavior is ...
Epidemiological, Molecular, and Clinical Features of Norovirus Infections among Pediatric Patients in Qatar
(
MDPI
