Solar photocatalytic degradation of 2-chlorophenol with ZnO nanoparticles: optimisation with D-optimal design and study of intermediate mechanisms
(
Springer Verlag
, 2017 , Article)
In this study, the photocatalytic degradation of toxic pollutant (2-chlorophenol) in the presence of ZnO nanoparticles (ZnO NPs) was investigated under solar radiation. The three main factors, namely pH of solution, solar ...
Effect of membrane performance including fouling on cost optimization in brackish water desalination process
(
Institution of Chemical Engineers
, 2017 , Article)
Membrane selection is a crucial step that will affect the economic feasibility of the membrane water treatment process. A comprehensive evaluation consisting of Verberne Cost Model, assessment of membrane performance and ...
Variation in temperature and light but not salinity invokes antioxidant enzyme activities in germinating seeds of Salsola drummondii
(
Taylor and Francis Ltd.
, 2016 , Article)
Seeds with efficient antioxidant defence system show higher germination under stress conditions; however, such information is limited for the halophyte seeds. We therefore studied lipid peroxidation and antioxidant responses ...
Improvement in Photovoltaic Performance of Dye Sensitized Solar Cell Using Activated Carbon-TiO2 Composites-Based Photoanode
(
IEEE Electron Devices Society
, 2016 , Article)
In this study, the activated carbon (AC) is synthesized from the oil fly ash (FA). Noncarbonaceous impurities were eliminated by acidic treatment of oil FA. Brunauer-Emmett-Teller and scanning electron microscopy ...
Rheological and thermal properties of novel surfactant-polymer systems for EOR applications
(
Wiley-Liss Inc.
, 2016 , Article)
In this work, two surfactant-polymer (SP) systems were evaluated for enhanced oil recovery applications. The first SP system contained partially hydrolyzed polyacrylamide and alkyl polyethylene glycol ether-based non-ionic ...
Enhanced photocatalytic degradation of a phenolic compounds' mixture using a highly efficient TiO2/reduced graphene oxide nanocomposite
(
Springer New York LLC
, 2016 , Article)
A nanocomposite (namely rGOTi) was prepared by loading 0.33 weight percent of reduced graphene oxide (rGO) on commercial TiO2 nanoparticles using a hydrothermal method. The as-prepared nanocomposite was characterized using ...
Cryopreservation of microalgae from desert environments of Qatar
(
Springer Netherlands
, 2016 , Article)
The Qatar University Culture Collection of Cyanobacteria and Microalgae (QUCCCM) is a unique resource containing a diverse collection of microalgae and cyanobacteria, isolated from the Qatar desert environment. In order ...
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 ...
Using block cipher for confidentiality of images in cloud-based systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
This paper deals with outsourcing of computing to cloud servers where clients' images are computed and stored. It proposes a technique that obfuscates images before sending them to servers. Cloud servers can perform ...
A comparative study on the performance of hybrid solar cells containing ZnSTe QDs in hole transporting layer and photoactive layer
(
Springer Netherlands
, 2016 , Article)
In this paper, ZnSTe quantum dots-based hybrid solar cells (HSC) with two different device architectures have been investigated. The improved performance of the poly(3-hexylthiophene) (P3HT) and [6,6]phenyl C71 butyric ...
