Unveiling one-pot scalable fabrication of reusable carboxylated heterogeneous carbon-based catalysts from eucalyptus plant with the assistance of dry ice for selective hydrolysis of eucalyptus biomass
(
Elsevier Ltd
, 2020 , Article)
Biomass is the most abundant source for organic carbon-based substances on the earth; however, its utilization as sources for heterogeneous catalysts for biorefineries is rarely reported. Herein, a simple approach was ...
Facile synthesis of metal-polyphenol-formaldehyde coordination polymer colloidal nanoparticles with sub-50 nm for T1-weighted magnetic resonance imaging
(
Elsevier B.V.
, 2021 , Article)
Plant polyphenol-based coordination polymers (CPs) with ultra-small particle size and tailorable compositions are highly desired in biomedical applications, but their synthesis is still challenging due to the sophisticated ...
Significant Toxic Effect of Carbon Nanofibers at the Early Stage of Embryogenesis
(
NLM (Medline)
, 2020 , Article)
Implementation of carbon nanofibers (CNFs) in biomedical applications have successful outcomes, however, they are still considered as a potential hazard. We herein used avian embryos at 3 days and its chorioallantoic ...
Fabrication of fouling resistant Ti3C2Tx (MXene)/cellulose acetate nanocomposite membrane for forward osmosis application
(
Elsevier Ltd
, 2020 , Article)
In this study, Ti3C2Tx (MXene) was used to enhance the fouling resistance of FO flat-thin film membranes. Mixed-matrix Ti3C2Tx (MXene)/ cellulose acetate (CA) membranes with different (wt%) loading of MXene were fabricated ...
Recent advance in synthesis and application of heteroatom zeolites
(
Elsevier B.V.
, 2021 , Article)
Incorporation of heteroatoms into the framework of zeolites has become a significant strategy to improve their performance in catalysis and adsorption, because the obtained heteroatom zeolites exhibit quite different ...
A review of MXenes as emergent materials for dye removal from wastewater
(
Elsevier B.V.
, 2022 , Article)
MXenes have emerged as a superlative contestant water purification technology due to their two-dimensional multilayered structures, multifarious chemical composition, photocatalytic properties, and activated metallic ...
Rational construction and triethylamine sensing performance of foam shaped a-MoO3@SnS2 nanosheets

This study reports on the development and implementation of the Student Learning Outcomes Assessment process and the system implemented at Qatar University. This system consists of two phases, initiation and enhancement, ...
One-pot microwave-assisted green synthesis of amine-functionalized graphene quantum dots for high visible light photocatalytic application
(
Elsevier Masson SAS
, 2019 , Article)
Nowadays, graphene quantum dots (GQDs) have gained a huge interest in the field of visible-range photocatalysts because of their tunable band gap and stable photochemical properties. In this work, amine-functionalized GQDs ...
Roll-over cyclometalation: A versatile tool to enhance the catalytic activity of transition metal complexes
(
Elsevier B.V.
, 2018 , Article)
Roll-over cyclometalation is a special case of cyclometalation. While in classical cyclometalation, C,H-activation (deprotonation or oxidative addition) has to occur at the ligand to result in a metallacycle, in roll-over ...
