The preparation, properties and applications of electrospun co-polyamide 6,12 membranes modified by cellulose nanocrystals
(
Elsevier Ltd
, 2017 , Article)
In this paper, we present the preparation and properties of a unique material system manufactured by electrospinning of co-polyamide 6,12 (coPA) from an n-propanol solution. A significant advantage of this system is that ...
Effect of halloysite nanotubes on the thermal degradation behaviour of poly(ε-caprolactone)/poly(lactic acid) microfibrillar composites
(
Elsevier Ltd
, 2017 , Article)
This paper reports on the thermal degradation behaviour and kinetics of halloysite nanotubes containing microfibrillated poly(ε-caprolactone) (PCL)/poly(lactic acid) (PLA) blends. It was found that the nanotubes probably ...
Propagation rate coefficient for sulfobetaine monomers by PLP-SEC
(
Elsevier Ltd
, 2016 , Article)
Zwitterionic polymers have been extensively used in the biomedical field, however, the knowledge about the kinetics and mechanism of radical polymerization of their monomers is limited. This work introduces the first ...
Corrosion protection of electrospun PVDF-ZnO superhydrophobic coating
(
Elsevier B.V.
, 2016 , Article)
A one-step electrospinning technique was used to prepare a protective superhydrophobic PVDF–ZnO nanocomposite coating for aluminum against corrosion. The wettability and morphology of the prepared coating surfaces was ...
3D architectures of titania nanotubes and graphene with efficient nanosynergy for supercapacitors
(
Elsevier Ltd
, 2017 , Article)
One dimensional titanium dioxide nanotubes (titania nanotubes or TNT) are grown on the surface of two dimensional graphene sheets by hydrothermal method so that desirable out of plane properties are obtained in the final ...
An automatic fast optimization of Quadratic Time-frequency Distribution using the hybrid genetic algorithm
(
Elsevier B.V.
, 2017 , Article)
This paper presents a novel framework for a fully automatic optimization of Quadratic Time-frequency Distributions (QTFDs). This ‘black box’ approach automatically adjusts the QTFD kernel parameters by using a hybrid genetic ...
Cure kinetics of epoxy/MWCNTs nanocomposites: Isothermal calorimetric and rheological analyses
(
Elsevier B.V.
, 2017 , Article)
A combinatorial route has been applied in cure kinetics study of epoxy nanocomposites containing multi-walled carbon nanotubes (MWCNTs) based on differential scanning calorimetry and rheokinetic analyses under isothermal ...
Prevalence of microplastics in the marine waters of Qatar
(
Elsevier Ltd
, 2016 , Article)
Microplastics are firmly recognized as a ubiquitous and growing threat to marine biota and their associated marine habitats worldwide. The evidence of the prevalence of microplastics was documented for the first time in ...
Review on recent advances in polythiophene based photovoltaic devices
(
Elsevier Ltd
, 2016 , Article Review)
Discovery of conducting polymer introduced us to the total polymeric solar cells (PSC). During the last decade, power conversion efficiency (PCE) of these solar cells has increased from 1% to 11.5% (with the bulk heterojunction ...
Melt processing and properties of linear low density polyethylene-graphene nanoplatelet composites
(
Elsevier Ltd
, 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 ...
