Refining source-oriented ecological-health risk assessments of soil potentially toxic elements using region-specific geochemical baseline values in a high geological background region

Naturally mineralized regions exhibit elevated geochemical backgrounds of soil potentially toxic elements (PTEs). However, the use of uniform geochemical baseline values (GBVs) frequently leads to misclassification between natural enrichment and anthropogenic contamination, hinde...

Coupling Effects of Texture Density and Counterpart Material Hardness on the Dry Sliding Friction of TC4 Titanium Alloy

Circular microtextures with area densities of 5%, 10%, 15%, and 20% were fabricated on TC4 titanium alloy surfaces and tested under dry sliding conditions against four counterpart balls of varying hardness (Brass, SUS304, AISI 52100, and K20). Through coefficient of friction (COF...
