Tailoring of the thermal, mechanical and dielectric properties of the polypropylene foams using gamma-irradiation
(
Elsevier Ltd
, 2016 , Article)
This study investigate the influence of gamma-irradiation (GI) doses from 0 up to 50 kGy on the polypropylene (PP) foams, mainly the impact on their structural and physical properties. It was found that structural properties ...
Universal power law behavior of the AC conductivity versus frequency of agglomerate morphologies in conductive carbon nanotube-reinforced epoxy networks
(
John Wiley and Sons Inc.
, 2016 , Article)
The Jonscher universal power law for ac conductivity versus frequency (f = /2) in the dispersion region was tested for a multiwall carbon nanotube/epoxy nanocomposite. The effect of changes in agglomerate morphology on the ...
Heat transfer performance of paraffin wax based phase change materials applicable in building industry
(
Elsevier Ltd
, 2016 , Article)
Thermal characterization of phase change materials (PCMs) compose of linear low-density polyethylene (LLDPE), paraffin wax (W) with a melting point of 25 °C, and expanded graphite (EG), that are highly effective in thermal ...
High performance sulfonic acid doped polyaniline–polystyrene blend ammonia gas sensors
(
Springer Nature
, 2016 , Article)
In this work, we present a method of preparation and sensing measurement of four camphorsulfonic acid (CSA) doped polyaniline–polystyrene blends (PANI–PS), where PANI is obtained by dispersion polymerization and blending ...
Melt processing and properties of linear low density polyethylene-graphene nanoplatelet composites
(
Elsevier
, 2016 , Article)
Composites of Linear Low Density Polyethylene (LLDPE) and Graphene Nanoplatelets (GNPs) were processed using a twin screw extruder under different extrusion conditions. The effects of screw speed, feeder speed and GNP ...
Why Do People Participate in Surveys in Qatar?
(
Asian Online Journal Publishing Group
, 2016 , Article & Poster)
In this paper, we assesses respondent participation in academic public opinion surveys in the State of Qatar. Rates of participation in SESRI’s face-to-face surveys remain at levels that far exceed those observed in Western ...
Effect of two types of graphene nanoplatelets on the physico-mechanical properties of linear low-density polyethylene composites
(
Taylor and Francis Ltd.
, 2016 , Article)
The influence of two types of graphene nanoplatelets (GNPs) on the physico-mechanical properties of linear low-density polyethylene (LLDPE) was investigated. The addition of these two types of GNPs - designated as grades ...
An Experimental and Kinetic Study of the Sorption of Carbon Dioxide onto Amine-Treated Oil Fly Ash
(
Hindawi Publishing Corporation
, 2016 , Article)
A new CO2 adsorbent is produced from waste oil fly ash (OFA). Ammonium hydroxide solution is used to convert OFA to activated carbon. Then, the product is used for the adsorption of CO2 from a nitrogen/carbon dioxide ...
Pilot-scale spiral wound membrane assessment for THM precursor rejection from upland waters
(
Taylor and Francis Inc.
, 2016 , Article)
The outcomes of a pilot-scale study of the rejection of trihalomethanes (THMs) precursors by commercial ultrafiltration/nanofiltration (UF/NF) spiral-wound membrane elements are presented based on a single surface water ...
