Raman spectroscopy of the Dukhan sabkha: identification of geological and biogeological molecules in an extreme environment
(
The Royal Society
, 2010 , Article)
The characterization of minerals and biogeological deposits in a terrestrial Arabian sabkha has a direct relevance for the exploration of Mars since the discovery by the NASA rovers Spirit and Opportunity of evaporate ...

Photochemical grafting of polysulfobetaine onto polyethylene and polystyrene surfaces and investigation of long-term stability of the polysulfobetaine layer in seawater
(
John Wiley and Sons Ltd
, 2018 , Article)
Low-density polyethylene (LDPE) and polystyrene (PS) films with hydrophilic surface were prepared by photochemical grafting of sulfobetaine-based copolymer containing photolabile moiety, and long-term stability of the ...
EFFECT OF COMPATIBILIZER ON MECHANICAL AND PHYSICAL PROPERTIES OF GREEN COMPOSITES BASED ON HIGH DENSITY POLYETHYLENE AND DATE PALM FIBER
(
DEStech Publications
, 2013 , Conference Paper)
Date palm leaves and wood are common wastes in the middle east. These natural fibers can be used as additives for polymers to develop new desired properties; they also have important economic and environmental advantages. ...
Joint replenishment model for multiple products with substitution
(
Elsevier Inc.
, 2016 , Article)
We extend the classical economic order quantity model to address the joint replenishment of multiple products under substitution. The proposed model optimizes ordering quantities for each product under substitution effects ...
Effect of Trace 100 vppm H2S on the Corrosion Behaviour of Plain Carbon and Microalloyed Steels in a Predominant Sweet Environment in High Flow Regime
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
We investigate the effects of the presence of trace (100 vppm) H2S on the corrosion behaviour of plain carbon steel and its various micro-alloyed counterparts in a CO2 saturated (sweet) brine (0.5 M NaCl) environment, in ...
Are mangroves in arid environments isolated systems? Life-history and evidence of dietary contribution from inwelling in a mangrove-resident shrimp species
(
Elsevier
, 2013 , Article)
The Arabian Gulf represents one of the more northerly extremes of mangrove distribution in the Indo-Pacific, and is populated only by Avicennia marina, due to its tolerance of high salinity and wide temperature extremes. ...
Preparation and Preliminary Dielectric Characterization of Structured C60-Thiol-Ene Polymer Nanocomposites Assembled Using the Thiol-Ene Click Reaction
(
MDPI
, 2015 , Article)
Fullerene-containing materials have the ability to store and release electrical energy. Therefore, fullerenes may ultimately find use in high-voltage equipment devices or as super capacitors for high electric energy storage ...

(
Politecnico di Torino - Department of Mechanical and Aerospace Engineering Italy
, 2012 , Conference Paper)
In this paper investigates the environment impact for recycle polypropylene which reinforced
with natural wood fiber by extrusion. The purpose of this work was to reduce the
environmental impact for the new products by ...
