Spatial mapping of the localized corrosion behavior of a magnesium alloy AZ31B tungsten inert gas weld [PDF]

Journal of Magnesium and Alloys
Sections of a magnesium alloy, AZ31B, joined with tungsten inert gas (TIG) welding, were examined with scanning electrochemical microscopy (SECM) and scanning Kelvin probe force microscopy (SKPFM) to investigate corrosion mechanisms by correlating ...

Molecular Doping of CVD-Graphene Surfaces by Perfluoroalkyl-Substituted Perylene Diimides Derivatives [PDF]

Nanomaterials, 2022
Non-covalent π-π and dipolar interactions with small aromatic molecules have been widely demonstrated to be a valid option to tune graphene work functions without adding extrinsic scattering centers for charge carriers.

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.
