Polycyclic aromatic hydrocarbons in dust from the indoor environment of Qatar
(
Hamad Bin Khalifa University Press
, 2016 , Conference Paper)
Polyaromatic Hydrocarbons (PAHs) concentrations in dust trapped on air conditioning unit filters operating in residential and workplace locations in Doha, Qatar were sampled and measured. Fourteen samples were collected ...
Two-stage cultivation of N-rich and N-deprived Acutodesmus obliquus biomass: Influence of cultivation and dewatering methods on microalgal biomass used in anaerobic digestion
(
Elsevier
, 2016 , Article)
Microalgae can be manipulated to accumulate certain cellular compounds of interest without the need for genetic modification - simply by controlling growth parameters such as nitrogen (N). Therefore, A. obliquus was ...
Anthropogenic related variations in the epibiotic biodiversity and age structure of the “Pearl Oyster” Pinctada radiata within the eulittoral zone of Qatar
(
Elsevier
, 2016 , Article)
Abstract Oyster aggregations provide critical habitat that contain diverse communities, with epibiota and oysters sensitive to environmental disturbance. The monitoring of oysters and associated organisms has become an ...
The influence of paraffin wax addition on the isothermal crystallization of LLDPE
(
Wiley
, 2016 , Article)
The influence of paraffin wax addition on the isothermal crystallization kinetics of linear low density polyethylene (LLDPE) was studied in a temperature range where the wax was always in the molten state and could be ...
Electrospun PVDF graphene oxide composite fibre mats with tunable physical properties.
(
Springer Verlag
, 2016 , Article)
This article is aimed at a basic physical characterization of electrospun PVDF/graphene oxide (GO) composite non-woven fibre mats. The morphological characterization of the prepared fabrics was performed via SEM investigations. ...
Plasticization and co-crystallization in LLDPE/wax blends.
(
Wiley Periodicals, Inc
, 2016 , Article)
The structure and thermal properties of linear low density polyethylene (LLDPE)/medium soft paraffin wax blends, prepared by melt mixing, were investigated by differential scanning calorimetry (DSC) and small- and wide-angle ...

This paper reports on an investigation of the influence of the presence of two different clays, Cloisite 15A
and Cloisite 30B, and fibre drawing on the degradation behaviour and kinetics of PCL/PLA composites. It
was ...
Influence of the Ce :YAG amount on structure and optical properties of Ce :YAG-PMMA composites for white LED
(
De Gruyter
, 2016 , Article)
Ce:YAG-poly(methyl methacrylate) (PMMA) composites were prepared by using a melt compounding method, adding several amounts of Ce:YAG in the range 0.1–5wt.%. The optical properties of the obtained composites and of the ...
Morphology and magnetic properties of the ethylene-co-vinyl acetate/iron nanocomposite films prepared by implantation with Fe6+ ions
(
Elsevier
, 2016 , Article)
Ethylene-co-vinyl acetate/iron nanocomposite films were fabricated by implantation with multiplecharged ions at different fluencies. The films obtained with ion fluency of 1 × 1017cm−2were used forspecific studies. It was ...
