Evaluation of the galvanic corrosion of high copper dental amalgams by means of electrochemical techniques

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
The galvanic interaction between three high copper dental amalgams with another four dental metallic materials, was evaluated. The dental amalgams were: a national Nu Alloy®dp (New Stetic) and two imported Contour®TM (Kerr, USA) and GS-80® (SDI ...

Zinc-rich paint coatings containing either ionic surfactant-modified or functionalized multi-walled carbon nanotube-supported polypyrrole utilized to protect cold-rolled steel against corrosion [PDF]

open access: yes, 2013
The intense anodic action of sacrificial zinc pigments ensured viable galvanic function of the highly porous liquid zinc-rich paints (ZRPs) result in deteriorated long-term corrosion resistance often accompanied by cathodic delamination phenomena. In our

Ultrafast Room‐Temperature Nanofabrication via Ozone‐Based Gas‐Phase Metal‐Assisted Chemical Etching for High‐Performance Silicon Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Locking Metastable Topological Domains in Nematic Liquid Crystal Pi Cells

open access: yesAdvanced Functional Materials, EarlyView.
Selective photopolymerization in the presence of a controlled voltage defines permanent director walls that lock‐in metastable bend and twist configurations within nematic liquid crystal Pi cells. Q‐tensor simulations corroborate the experiments, demonstrating the topological state stabilization.
