(
Springer New York LLC
, 2018 , Article)
The exceptional chemical and physical properties of nanostructured materials are extremely suitable for designing new and enhanced sensing devices, particularly gas sensors and biosensors. The present work describes the ...
Institutional arrangements for beneficial regional cooperation on water, energy and food priority issues in the Eastern Nile Basin
(
Elsevier B.V.
, 2018 , Article)
Research on water cooperation in the Eastern Nile Basin has focused on expanding policy and diplomacy tools for a better allocation of transboundary water resources confined to the river. Regional cooperation on water and ...
Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells
(
Elsevier B.V.
, 2018 , Article)
In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ...
Decline in oyster populations in traditional fishing grounds; is habitat damage by static fishing gear a contributory factor in ecosystem degradation?
(
Elsevier
, 2018 , Article)
The territorial waters of Qatar once supported dense assemblages of the pearl oyster Pinctada radiata. The oysters settled on a patchy network of limestone platforms (hairãt) and provided a suite of ecosystem services to ...
Light-controllable viscoelastic properties of a photolabile carboxybetaine ester-based polymer with mucus and cellulose sulfate
(
Springer Nature
, 2018 , Article)
In this study, the interaction of a photoswitchable carboxybetaine ester-based polymer with mucus and cellulose sulfate was elucidated, showing light-controllable viscoelastic properties. This polymer contains photolabile ...
Emerging clay-aryl-gold nanohybrids for efficient electrocatalytic proton reduction
(
Elsevier
, 2018 , Article)
There is an ever growing demand for renewable sources of energy to replace conventional fossil fuels. One of the alternatives is usage of hydrogen production by electrochemical hydrogen evolution reaction (HER). Toward ...
A resource provisioning framework for bioinformatics applications in multi-cloud environments
(
Elsevier
, 2018 , Article)
The significant advancement in Next Generation Sequencing (NGS) have enabled the generation of several gigabytes of raw data in a single sequencing run. This amount of raw data introduces new scalability challenges in ...
Foamy phase change materials based on linear low-density polyethylene and paraffin wax blends
(
Springer Nature
, 2018 , Article)
Foamy phase-change materials (FPCMs) based on linear low-density polyethylene (LLDPE) blended with 30 wt.% of paraffin wax (W) were successfully prepared for the first time. The advantage of these materials is their double ...
Template-assisted growth of nanoporous VTTBNc films: Morphology and moisture sensitivity studies
(
Elsevier B.V.
, 2018 , Article)
A novel structured of nanoporous vanadyl 2,11,20,29-Tetra Tert-Butyl 2,3 Naphthalocyanine (VTTBNc) films were prepared by template-assisted method. The structure and morphology of the fabricated VTTBNc nanostructures were ...
Bentonite-decorated calix [4] arene: A new, promising hybrid material for heavy-metal removal
(
Elsevier
, 2018 , Article)
There is global concern about the contamination of ground, river, and tap waters as well as soil contamination with heavy metal ions; these chemical species are known to not degrade and to cause severe health problems if ...
