Continuous packed bed column removal of Cr6+, Cd2+, and Pb2+ ions from synthetic wastewater using polymeric ultra‐permeable and biodegradable ferromagnetic nanocomposite membrane

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Enhanced separation of used adsorbent with an external magnet. Abstract Water purification techniques, including membrane technologies, ion exchange and adsorption, chemical/biochemical reduction, and electrochemical processes, have been developed to remove/recover metal ions species from polluted wastewater.

A critical study of sustainable biocomposites developed from rheologically distinct poly(butylene adipate‐co‐terephthalate) (PBAT) reinforced with biocarbon from coconut (Cocos nucifera) for rigid applications

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This work highlights the development of a sustainable composite with improved dimensional and thermal stability as well as mechanical performance, for rigid application. To promote sustainability and a circular economy, we have reduced PBAT percentage content by half and incorporated waste coconut shell up to 50 wt.%.

Flexural Behavior and Design of Prestressed Ultra-High Performance Concrete (UHPC) Beams: Failure Mode and Ductility [PDF]

open access: yesarXiv
Ultra-high performance concrete (UHPC) is well-known for its ultra-high compressive strength and sustained post-cracking tensile ductility, making it an attractive choice for the construction of modern structures. Prestressed UHPC members, however, often fail quickly after crack localization accompanied by reinforcement rupture, which shows limited ...

Seismic performance of concrete tunnel–sand–pile interaction by the shake table test

open access: yesDeep Underground Science and Engineering, EarlyView.
This research presents the square root sum of squares response of displacements and tunnel moments under the Kobe and Loma Prieta seismic excitations with a peak ground acceleration of 0.05 g for various dry relative densities of local sand in Bangladesh.
