Ordering-mediated local nano-clustering results in unusually large Hall-Petch strengthening coefficients in high entropy alloys
This article reports a dramatic increase in the grain boundary strengthening or Hall-Petch coefficient, K, by systematically investigating the effect of Al addition on tensile yield strength in CoFeNi and CoCrFeNi high entropy alloys (HEAs) or complex concentrated alloys (CCAs). Such a trend is attributed to the ordering mediated nano-clustering in Al containing HEA/CCAs.

Sol-gel synthesized indium tin oxide as a transparent conducting oxide with solution-processed black phosphorus for its integration into solar-cells
This article describes the synthesis of indium tin oxide (ITO) thin films using solgel processing with a mixture of InCl₃, methanol, and SnCl₂, where the solutions were spin coated onto glass substrates. The combined architecture of black phosphorus on ITO thin films shows promise in its use for transparent electronics, which can also serve as a stepping stone for future solar cell platforms.
