TL;DR: In this article, the environmental geochemistry of molybdenum and tungsten is not well known, and the authors use batch equilibria to predict Mo and W concentrations in the presence of ferrihydrite (hydrous ferric oxide).

TL;DR: In this article, an analysis of the balling mechanism reveals that melting is a process where melt spreading and solidification compete with each other and the final result is determined by intrinsic tungsten properties and the set laser processing parameters, and it was observed that balling of melted droplets at the laser focal points and entrapped cavities hindered the preparation of fully dense parts.

TL;DR: In this article, the potential of metallic nanoparticles for use in ultraviolet plasmonics (3-6 eV) applications was assessed by an exhaustive numerical analysis, and the potential for applications such as surface-enhanced Raman spectroscopy, accelerated photodegradation and photocatalysis was addressed.
Abstract: The practical efficacy of technologically promising metals for use in ultraviolet plasmonics (3–6 eV) is assessed by an exhaustive numerical analysis. This begins with estimates of the near- and far-field electromagnetic enhancement factors of isolated hemispherical and spherical metallic nanoparticles deposited on typical dielectric substrates like sapphire, from which the potential of each metal for plasmonic applications may be ascertained. The ultraviolet plasmonic behavior of aluminum, chromium, copper, gallium, indium, magnesium, palladium, platinum, rhodium, ruthenium, titanium, and tungsten was compared with the well-known behavior of gold and silver in the visible. After exploring this behavior for each metal as a function of nanoparticle shape and size, the deleterious effect caused by the metal’s native oxide is considered, and the potential for applications such as surface-enhanced Raman spectroscopy, accelerated photodegradation and photocatalysis is addressed.
