Batch study for herbicide bentazon adsorption onto palm oil fronds activated carbon
(2012 , Article)
The adsorption of herbicide bentazon from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both; initial concentration of the bentazon (ranging ...
Treatment as prevention for hepatitis C virus in the Middle East and North Africa: a modeling study
(
Frontiers Media SA
, 2023 , Article)
Background: Direct-acting antivirals opened an opportunity for eliminating hepatitis C virus (HCV) infection in the Middle East and North Africa (MENA), the region most affected by HCV infection. Impact of HCV treatment ...
Conformal Invariants in Simply Connected Domains
(
Springer Link
, 2020 , Article)
This paper studies the numerical computation of several conformal invariants of simply connected domains in the complex plane including, the hyperbolic distance, the reduced modulus, the harmonic measure, and the modulus ...
Turning waste avocado stones and montmorillonite into magnetite-supported nanocomposites for the depollution of methylene blue: adsorbent reusability and performance optimization
(
Springer Nature
, 2023 , Article)
The existence of methylene blue (MB) in wastewater even as traces is raising environmental concerns. In this regard, the performances of four adsorbents, avocado stone biochar (AVS-BC), montmorillonite (MMT), and their ...
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 ...
Efficient electrochemical conversion of CO2 into formic acid using colloidal NiCo@rGO catalyst
(
Elsevier
, 2024 , Article)
A simple approach was used to synthesize a catalyst based on colloidal NiCo with rGO support. The catalyst was uniformly deposited on acid-treated Sn foil using drop-casting method. The prepared NiCo@rGO catalyst was ...

Heart disease remains a global leading cause of death and disability, necessitating a comprehensive understanding of the heart’s development, repair, and dysfunction. This review surveys recent discoveries that explore the ...
Academic self-concept and its relationship to academic achievement among university students.
(2022 , Article)
This research sought to study the academic self-concept and the relationship between the academic self-concept and students’ academic achievement among university Qatari students. Research of the academic self-concept is ...
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 ...
The effect of graphene on the activation energy of grain growth for the nanocrystalline thermoelectric n-type Bi2Te2.7Se0.3
(
Springer Nature
, 2022 , Article)
Even though bismuth telluride is frequently produced by mechanical alloying for thermoelectric materials, no data has been published addressing the thermal behavior and activation energy of the milled n-type Bi2Te2.7Se0.3 ...
