Multiresponse Tribological Ranking Alternatives of Al–Cu Alloys via an Integrated Taguchi Experimental Design, AHP Weighting, and WASPAS Decision Framework

Engineering Reports, Volume 8, Issue 5, May 2026.
To optimize aluminium–copper alloy compositions and tribological parameters for improved wear performance using an integrated hybrid MCDM approach. The Al–Cu alloy compositions were fabricated through die casting. Their tribological performance was evaluated and optimized using a hybrid Taguchi–AHP–WASPAS methodology under varying loads, sliding speeds,

Phytoremediation of Wastewater From Oil Well Drilling: Potential of Different Plant Species

Water Environment Research, Volume 98, Issue 5, May 2026.
Purple fountain grass (Cenchrus setaceus “Rubrum”) is a promising plant for using in constructed wetlands treating complex oil drilling effluents. ABSTRACT This study evaluated the removal of contaminants present in wastewater from oil well drilling in the presence of three plant species: water hyacinth (Eichhornia crassipes), cattail (Typha ...

Carbohydrate–Protein Hydrogels as Fat Replacers: Design Criteria and Benchmarking Against Full‐Fat Systems

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Reducing saturated fat while preserving the sensory quality of full‐fat foods remains a major formulation challenge because fat contributes simultaneously to body, lubrication, flavor delivery, and thermal transitions. Carbohydrate–protein (CP) hydrogels are increasingly explored as oil‐free fat replacers, but many systems are developed and ...
