Use of lignite as a low-cost material for cadmium and copper removal from aqueous solutions: Assessment of adsorption characteristics and exploration of involved mechanisms
(
MDPI
, 2021 , Article)
Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ...
Co-doped zigzag graphene nanoribbon based gas sensor for sensitive detection of H2S: DFT study
(
Academic Press
, 2021 , Article)
In this work, we present a highly sensitive gas sensor for the detection of poisonous hydrogen sulfide gas (H2S) based on copper and zinc co-doped zigzag graphene nanoribbon (Cu/Zn-ZGNR). The electronic properties as well ...
A framework for the analysis of damage and recovery characteristics of asphalt mixtures
(
Taylor & Francis
, 2020 , Article)
This study presents two approaches for evaluating damage and recovery characteristics of asphalt mixtures. The first approach focuses on determining damage by extracting recoverable viscoelastic strain that has no damage ...
Sludge-derived biochars: A review on the influence of synthesis conditions on pollutants removal efficiency from wastewaters
(
Elsevier
, 2021 , Article)
Pyrolysis is a thermochemical process that permits the conversion of biomasses into energy (bio-oil and biogas) and a solid residue called biochar. The generation of biochar from lignocellulosic materials has been, for ...
Forced vibration characteristics of embedded graphene oxide powder reinforced metal foam nanocomposite plate in thermal environment
(
Elsevier
, 2021 , Article)
Dynamic behavior of a new class of nanocomposites consisted of metal foam as matrix and graphene oxide powders as reinforcement is presented in this study in the framework of forced vibration. Graphene oxide powders are ...
Microstructure and mechanical behavior of hot extruded aluminum/tin-bismuth composites produced by powder metallurgy
(
MDPI AG
, 2020 , Article)
In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the ...
Magnetorheological elastomer-based variable stiffness flexible coupling for vibration isolation
(
Canadian Science Publishing
, 2021 , Article)
Rotating mechanical equipment such as pumps and motors can suffer from unattenuated torsional vibration. The causes of such vibration range from imbalance within the rotating system to misalignment, or even operating at ...
Electrodeposition of Duplex Ni–B–Zn/Co Composite Coatings
(2020 , Article)
This research article focusses on the Ni–B–Zn/Co composite coatings synthesized via an electrodeposition process. Electrodeposited Ni–B composite coatings have several advantages, such as excellent corrosion as well as ...
WEALTH AND THE PERSISTENCE OF AUTHORITARIANISM IN THE GULF STATES: ECONOMIC PRIVILEGE OR A CULTURAL PHENOMENON?
(
Foundation for Good Politics
, 2021 , Article)
During the Arab Spring the idea of the Middle East as an authoritarian exception appeared to be no longer valid. Yet the Gulf states seem to be safe from political turmoil. This paper examines the persistence of authoritarianism ...
Highly crystalline and thermally stable poly(aniline-co-2-nitroaniline)
(
Springer Nature
, 2020 , Article)
Abstract: To synthesize a crystalline polymer is unconventional. Here, we found the well-defined hexagonal or rectangular cubical shape of poly(aniline-co-2-nitroaniline)s PA-co-2-NAs through scanning electron microscopy. ...
