Entropy Landscaping of High-Entropy Carbides
Mohammad Delower Hossain,Trent Borman,Corey Oses,Marco Esters,Cormac Toher,Lun Feng,Abinash Kumar,William G. Fahrenholtz,Stefano Curtarolo,Donald W. Brenner,James M. LeBeau,Jon Paul Maria +11 more
TL;DR: In this article, the entropy landscape of high-entropy carbides is used to understand and predict their structure, properties, and stability, using first principles calculations, the individual and temperature-dependent contributions of vibrational, electronic, and configurational entropies are analyzed, and compare them qualitatively to the enthalpies of mixing.

Kate Reidy,Georgios Varnavides,Joachim Dahl Thomsen,Abinash Kumar,Thang Pham,Arthur M. Blackburn,Polina Anikeeva,Prineha Narang,James M. LeBeau,Frances M. Ross +9 more
TL;DR: In this article, advanced scanning transmission electron microscopy techniques are used to image the atomic structure at the interface between 2D MoS2 and 3D Au nanoislands, revealing a moire superlattice and illustrating the potential for (to-)electronic moire engineering at the 2D/3D interface.
