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 ...
Effective NiMn nanoparticles-functionalized carbon felt as an effective anode for direct urea fuel cells
(
MDPI AG
, 2018 , Article)
The internal resistances of fuel cells strongly affect the generated power. Basically, in the fuel cell, the anode can be prepared by deposition of a film from the functional electrocatalyst on a proper gas diffusion layer. ...
Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process
(
MDPI
, 2019 , Article)
In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with ...
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 Ag nanoparticles on state of the art MnO2 nanorods performance as an electrocatalyst for lithium air batteries
(
Elsevier
, 2018 , Article)
Abstract The need for an alternative and efficient electrocatalyst to replace Pt-based noble materials is a goal of prime importance in Li– air battery technology. In this work, novel silver nanoparticles-incorporated MnO2 ...
Preparation and characterization of wollastonite/titanium oxide nanofiber bioceramic composite as a future implant material
(
Elsevier
, 2016 , Article)
In this study, novel composites consisting of electrospun titanium dioxide (TiO2) nanofibers incorporated into high-purity wollastonite glass ceramics were prepared as materials for use in hard tissue engineering applications. ...
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 ...
The potential impact data of Tylosin and Enrofloxacin veterinary antibiotics on germination and accumulation in barley seed as a forage crop and good dietary sources using LC/MS-MS
(
Elsevier
, 2019 , Article)
In this study, the phytotoxic effects caused by the exposure to five different concentrations of two veterinary antibiotics (Tylosin, and Enrofloxacin) that are commonly used for the treatment of farm animals as antibacterial ...
Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.
(
Nature Research
, 2019 , Article)
Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates ...
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 ...
