Development of sustainable geopolymer composites for repair application: Workability and setting time evaluation
(
Elsevier
, 2023 , Other)
One of the most used construction materials worldwide is concrete. It has a lot of advantages over the other construction materials. However, the production process of concrete produces a huge amount of carbon dioxide. ...
Synthesis and characterization of sodium alginate/polyvinyl alcohol/zinc oxide/iron oxide nanocomposites for electrochemical applications
(2023 , Article)
Polymer nanocomposites films, based on sodium alginate (NaAlg) and polyvinyl alcohol (PVA) complexed with zinc oxide nanoparticles (ZnO NPs) and iron oxide nanorods (Fe3O4 NRs) as nanofiller, were prepared by solution ...
Electrochemical Nonenzymatic Acetone Sensing: A Novel Approach of Biosensor Platform Based on CNT/CuO Nanosystems
(
John Wiley and Sons Inc
, 2023 , Article)
A promising approach for noninvasive medical diagnosis may be to measure the VOCs produced by metabolic changes or pathological disorders in human sweat, such as measuring the acetone levels in the presence of diabetes. ...
Integrating of electrocoagulation process with submerged membrane bioreactor for wastewater treatment under low voltage gradients
(
Elsevier
, 2023 , Article)
Treating and reusing wastewater has become an essential aspect of water management worldwide. However, the increase in emerging pollutants such as polycyclic aromatic hydrocarbons (PAHs), which are presented in wastewater ...
Electrocatalytic CO oxidation on porous ternary PdNiO-CeO2/carbon black nanocatalysts: Effect of supports and electrolytes
(
Elsevier
, 2023 , Article)
The catalytic activity and durability of porous ternary Pd-based electrocatalysts are augmented by alloying with other metals and using supports, however, the effect of supports and electrolytes at varied pH on the ...
Porous transition metal-based nanostructures as efficient cathodes for aluminium-air batteries
(
Elsevier
, 2023 , Article)
Aluminum-air batteries (AABs) are green and efficient energy systems due to their earth-abundant, safety, low price, excellent theoretical capacity (2.98 Ah/g) and energy density (8.1 Wh/g), which are significant merits ...
A comparison between iron and mild steel electrodes for the treatment of highly loaded grey water using an electrocoagulation technique
(
Elsevier
, 2023 , Article)
In the last years, the electrocoagulation (EC) process has been widely used as a potential technique for grey water treatment. However, only a few studies have focused on treating highly loaded GW (HLGW) by EC. In this ...
Self-Standing Pd-Based Nanostructures for Electrocatalytic CO Oxidation: Do Nanocatalyst Shape and Electrolyte pH Matter?
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2023 , Article)
Tailoring the shape of Pd nanocrystals is one of the main ways to enhance catalytic activity; however, the effect of shapes and electrolyte pH on carbon monoxide oxidation (COOxid) is not highlighted enough. This article ...
Novel surface-treatment for bottom ash from municipal solid waste incineration to reduce the heavy metals leachability for a sustainable environment
(
Elsevier
, 2023 , Article)
Unconventional treatments can provide a modification to convert ash waste into valuable materials that can be used in various applications. This study focuses on bottom ash (BA) collected from a local incineration plant ...
Repair of Heat-Damaged RC Beams Using Micro-concrete Modified with Carbon Nanotubes
(
Korean Society of Civil Engineers
, 2021 , Article)
This paper investigates the use of micro-concrete modified with carbon nanotubes (CNTs) for the repair of heat-damaged reinforced concrete (RC) beams. Ten RC beams were cast and then subjected to elevated temperature of ...
