Sub-Microscopic Phenomena of Metallic Corrosion Studied by a Combined Photoelectron Spectroscopy in Air (PESA) and Scanning Kelvin Probe Force Microscopy (SKPFM) Approach

International Journal of Electrochemical Science, 2012
The management of metallic corrosion has relied on large-scale, ultra-conservative protection strategies such as the extensive use of anti-corrosion metals and alloys, all-inclusive coating and surface passivation, and substantial use cathodic protection.

Surface Defects Control Bulk Carrier Densities in Polycrystalline Pb-Halide Perovskites. [PDF]

Adv Mater
Doping, the controlled addition of imperfections or impurities to a material, is crucial for semiconductors. This study shows that for Halide Perovskites, which have (very) low (intrinsic) defect densities because of effective self‐healing and defect tolerance, the title's statement holds in an unprecedented fashion.

TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...
