Cobalt Tungstate Characterization Using Matryoshka‐Structure Filter
Advanced Engineering Materials, EarlyView.The green synthesis of cobalt tungstate (CoWO4) using natural polymerizing agents from agar–agar and commercial produces environmentally friendly materials with tunable structural and electromagnetic properties. X‐ray diffraction and Rietveld refinement correlate crystal structure with microwave transmission losses in Matryoshka‐type filters.

Production of Metallic Foam Precursors Using Current‐Activated Pressure‐Assisted Densification
Advanced Engineering Materials, EarlyView.A powder compaction metallurgical method, known as current‐activated pressure‐assisted densification, is applied to enhance the compaction of metal foam precursors. This method improves precursor quality by achieving higher density, lower electrical resistivity, and more uniform pore nucleation in the resulting foams, reducing energy consumption and ...

Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles
Advanced Engineering Materials, EarlyView.Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

Advanced Engineering Materials, EarlyView.This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...
