Friction between Cohesive Soils and Steel

Soils and Foundations, 1993
ABSTRACT Laboratory tests on friction between cohesive soils and mild steel were carried out using a direct simple shear type of test apparatus. The cohesive soils were normally consolidated Kawasaki clay and four kinds of normally consolidated sand-clay mixtures. All tests were carried out under consolidated drained shear condition.

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain
