Polyimide-Based Flexible Microelectrode Array for Non-Invasive Transcorneal Electrical Stimulation

open access: yesSensors
Transcorneal electrical stimulation (TES) is a promising treatment for several retinal degenerative diseases (RDDs). TES involves the application of a controlled electrical current to the anterior surface of the cornea, aimed at activating the retina and

The Corrosion Behavior of C-steel, Al-alloy and Pure-Cu in Red Oak Wood Extract: A Comparative Study

open access: yesInternational Journal of Electrochemical Science, 2019
The corrosion behavior of three metals (C-steel, Al-alloy, and Pure-Cu) in the red oak wood extract (ROWE) had been studied using weight loss (expressed as thickness loss), potentiodynamic polarization and electrochemical impedance spectroscopy.

Measurements of interactions between acoustic fields and nonuniform mean flow [PDF]

open access: yes, 1980
Two problems crucial to the stability of longitudinal acoustic waves in solid rocket motors are examined experimentally. The first is the dissipation of energy associated with an average flow inward at the lateral boundary.

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

Corrosion resistance of Cu-Fe deformation processed in situ alloy in chloride ion environment

open access: yesElectrochemistry Communications
To assess the corrosion resistance of Cu-Fe deformation in situ alloys in a chloride ion environment, Cu-Fe alloys with varying Fe contents (5 wt%, 10 wt%, and 14 wt%) were prepared using vacuum induction melting, and the impact of Fe content on the ...
