Electric Solar sail (ESAIL) tethers may be subjected to barrage of incident charged particles, high energy photons and strong vibrations, depending on their working mechanism. Atomic Layer Deposition (ALD) technique can produce light-weight, conformal and defect-free coatings that can protect the metallic tethers from many anticipated harsh space effects. In addition to this, the coatings may be used to steer the equilibrium temperature of the tethers, especially when used in the deep solar system.

In this article, we propose the fabrication of ZnO nanostructures through the thermal oxidation of ball-milled doped powders. We investigate the applications, advantages, and challenges of this two steps process for the production and fabrication of high-quality and high-performance nanowires to be used in a large variety of applications.

Candida albicans is the most common pathogenic fungus that is isolated in nosocomial infections in medically and immune-compromised patients. The ability of C. albicans to convert its form from yeast to hyphal morphology contributes to biofilm development that effectively shelters Candida against the action of antifungals molecules. In the last years, nanocomposites are the most promising solutions against drug-resistant microorganisms.
