(
Elsevier
, 2020 , Article)
© 2020 Bacillus thuringiensis (Bt) is a Gram-positive soil bacterium that has been recognized as an effective bioinsecticide active against plant, animal and human pathogenic and disease vector insects. During its sporulation ...
Investigation on the effect of LiTFSI salt on PVDF-based Solid Polymer Electrolyte Membranes for Lithium-Ion Batteries
(
Qatar University Press
, 2021 , Poster)
Solid polymer electrolytes provide an alternative approach to providing improved safety whilst concurrently acting as a performance enhanced separator within Lithium-ion batteries (LIBs). This investigation studies the ...
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 ...
Detecting Organic Nitrogen with 1H-15N HMBC Spectra
(
Qatar University Press
, 2021 , Poster)
NMR spectroscopy has been the most important tool for organic chemistry research, providing detailed structure information. While 1H and 13C NMR spectra were frequently measured, 15N NMR spectra were relatively rare, even ...
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. ...
Electrolytic oxidation as a sustainable method to transform urine into nutrients
(
MDPI
, 2020 , Article)
© 2020 by the authors. In this work, the transformation of urine into nutrients using electrolytic oxidation in a single-compartment electrochemical cell in galvanostatic mode was investigated. The electrolytic oxidation ...
