Article Synopsis
- Researchers need nanocrystals with specific shapes for better catalysts, but traditional methods don’t allow for shape control.
- This study successfully synthesized concave platinum nanocubes with {110} facets and showed how they grow on a Pt(111) support, creating detailed nanostructured surfaces.
- By carefully selecting the support's crystallographic orientation, scientists can selectively immobilize desired nanostructures from a mixed solution, leading to new possibilities in nanocrystal development.
Oxidative stress is considered as an important factor and an early event in the etiology of Alzheimer's disease (AD). Cu bound to the peptide amyloid-β (Aβ) is found in AD brains, and Cu-Aβ could contribute to this oxidative stress, as it is able to produce in vitro H2O2 and HO˙ in the presence of oxygen and biological reducing agents such as ascorbate. The mechanism of Cu-Aβ-catalyzed H2O2 production is however not known, although it was proposed that H2O2 is directly formed from O2 via a 2-electron process.

This was made possible by the use of a new water-soluble chelator, the properties of which have also been described. Changes in the peptide sequence that impact Zn affinity are briefly discussed.
