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,

Design of a test rig for grease endurance tests
Results in EngineeringBackground: The performance and endurance of lubricating greases is often assessed through model tests (like four-ball tests or SRV tests). This approach has some limitations, especially when greases with special fillers are investigated, because ...

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 ...

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 ...

Correlation between System Entropy and Structural Changes in Lubricating Grease
Lubricants, 2015 Lubricating greases are colloid disperse systems consisting of a base oil and a thickener (additional additives). The lubricant is modeled as a tribological system, and the reaction of a fluid friction stress is investigated.
