Oxyacetylene torch testing and microstructural characterization of tantalum carbide [PDF]
SummaryTantalum carbide samples have been subjected to high‐temperature testing at ∼2300°C using an oxyacetylene torch to evaluate their potential for ultra‐high temperature applications. While large samples cracked during the rapid heating, indicating their inability to withstand thermal shock, small samples survived the severe test conditions.

Core‐passivation: A concept for stable core‐shell nanoparticles in aqueous electrocatalysis
The stability of nanoparticles is a major challenge in thermal and electrocatalysis. This is especially true for core‐shell nanoparticles where only a few monolayers of noble metal protect the usually non‐noble core material. In this work, we utilize the
