Isolation, screening and activity of hydrocarbon-degrading bacteria from harsh soils
(
Avestia Publishing
, 2016 , Conference Paper)
The study of microbial communities in relation to their ecology, interaction, and genetics must be covered in Qatar with special soil, weather and water. Microorganisms of an environment never having been exposed to such ...
Synthesis of thioether-functional poly(olefin)s via ruthenium-alkylidene initiated ring-opening metathesis polymerization
(
John Wiley and Sons Inc.
, 2019 , Article)
Ring-opening metathesis polymerization (ROMP) of thioether-derived oxanorbornene imide (M1) and its copolymerization with various cycloolefin comonomers such as cyclopentene (M2), cyclopent-3-en-1-ol (M3), cycloheptene ...
Engineering of nickel based catalyst for direct urea fuel cell-energy from municipal liquid waste (Mlw)
(
Nova Science Publishers, Inc.
, 2019 , Book chapter)
Alternatives to conventional fuels are required to meet the global energy demand, urea is a relatively non-toxic crystalline substance that is perhaps best known for its presence in municipal liquid waste (MLW) and ...
Assessment Of The Global Fallout Of Plutonium Isotopes In The Topsoil Of Qatar: Establishing A Baseline Concentrations Of 238pu, 239pu, And 240pu
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
A radio-analytical technique for determination of plutonium (Pu) isotopes in soil samples is tested against NIST and IAEA standard reference materials to determine its accuracy and precision for reliable results. The ...
Microplastics in coastal environments of the Arabian Gulf
(
Elsevier Ltd
, 2017 , Article)
Eight sandy beaches along the coastline of Qatar and four sea surface stations on the eastern coast, adjacent to Doha Bay, were surveyed between December 2014 and March 2015. Microplastics, mainly low density polyethylene ...
A combined pathway for the synthesis of nitidine family alkaloids
(
Springer Netherlands
, 2019 , Article)
Three related alkaloids, oxynitidine, nitidine and 5,6-dihydronitidine, have been afforded by the new synthetic protocols. In this approach, the Ni-catalyzed annulation reaction is indicated as the key step to construct ...
Influence of bimetallic nanoparticles composition and synthesis temperature on the electrocatalytic activity of NiMn-incorporated carbon nanofibers toward urea oxidation
(
Elsevier
, 2018 , Article)
High efficiency, cost effectivity and the availability of hydrogen are the advantages of
electrolysis as a strategy for urea-containing wastewater treatment. Composition,
morphology, and synthesis-temperature distinctly ...
Mediation of carbonate minerals formation by aerobic bacterial strains isolated from Dohat Faishakh Sabkha in Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Carbon dioxide (CO2) is increasingly released to the environment as a result of the extensive use of various industrial facilities. According to the Intergovernmental Panel on Climate Change Report (2015), cumulative ...
Synthesis of 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles and features of their NMR spectra
(
Wiley
, 2019 , Article)
Two different methods leading to 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles were investigated. Reactions of 3-aminocrotonirile with substituted salicylaldehydes provided 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles ...
Influence of nitrogen doping on the electrocatalytic activity of Ni-incorporated carbon nanofibers toward urea oxidation
(
Elsevier Ltd
, 2017 , Article)
Overall, boosting the formation of the active NiOOH layer distinctly improves the electro catalytic activity of nickel-based materials. Moreover, due to the adsorption capacity, the carbonaceous supports improve the ...
