Effect of reflected Ar neutrals on tantalum diboride coatings prepared by direct current magnetron sputtering

ABSTRACT: The magnetron sputtered tantalum diboride (TaBy) coatings from stoichiometric TaB2 target are often reported to be deposited in broad B/Ta interval with diverse structure and mechanical properties. In this article, the effect of Ar neutrals reflected from...

Durability characterization of mechanical interfaces in solar sail membrane structures

ABSTRACT: The construction of a solar sail from commercially available metallized film presents several challenges. The solar sail membrane is made by seaming together precut lengths of ultrathin metallized polymer film into the required geometry. This assembled sail...

Electrochemical preparation and homogenization of face-centered FeCoNiCu medium entropy alloy electrodes enabling oxygen evolution reactions

ABSTRACT: The exploitation of facile preparation methods and novel applications of entropy alloys has gained ever-increasing attention in recent years. In this paper, homogeneous FeCoNiCu medium entropy alloys (MEAs) with a face-centered cubic (FCC) structure are...
