Sustainable alkali-activated binders with municipal solid waste incineration ashes as sand or fly ash replacement
(
Springer Nature
, 2022 , Article)
The present study investigates the feasibility of using two types of municipality solid wastes incineration ashes, namely, fly ash and bottom ash in the production of sustainable alkali-activated binder. The ashes are ...
Structural equation modeling of public transport use with COVID-19 precautions: An extension of the norm activation model
(
Elsevier
, 2021 , Article)
This study aims to identify the travelers' attitudes and preferences towards the use of public transport during COVID-19 through the Norm-Activation Model (NAM). A questionnaire survey was designed to assess the traveler's ...
Factors Affecting the Performance of Sub-1 GHz IoT Wireless Networks
(
Hindawi Limited
, 2021 , Article)
Internet of Things (IoT) devices frequently utilize wireless networks operating in the Industrial, Scientific, and Medical (ISM) Sub-1 GHz spectrum bands. Compared with higher frequency bands, the Sub-1 GHz band provides ...

(
American Chemical Society
, 2020 , Article)
The spinel structure LiNi0.5Mn1.5O4 (LNMO) is a propitious cathode material for next-generation lithium-ion batteries for fast charge-discharge applications, but its capacity decay mechanism and rate-limiting process are ...
Monitoring the variation of soil quality with sewage sludge application rates in absence of rhizosphere effect
(
Elsevier
, 2020 , Article)
Agricultural soils in semi-arid regions have frequently been degraded due to adverse climatic conditions, organic matter depletion, and poor farming practices. To enhance soil quality, this study examines the reuse of ...
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 ...
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 ...
