Superconductivity in Metastable KMoSe: A Potassium-Intercalated Chevrel Phase.

The Chevrel phase (CP), characterized by its unique MoX (X = S, Se, Te) cluster structure, represents a class of promising materials demonstrating exceptional performance in various applications, including battery cathodes, electrocatalysts, and superconductors. However, the exploration of new CP derivatives remains challenging due to the inherent lattice destabilization caused by cation intercalation, particularly evident in selenide and telluride systems. This study reports the successful synthesis of thermodynamically metastable KMoSe ( ∼ 0.

Government regulation or market mechanism? A study on the collaborative innovation pathways of the emergency industry based on evolutionary game models.

Promoting collaborative innovation within the emergency industry has become a crucial task, which is of great significance for enhancing emergency response capabilities and ensuring public safety. On the basis of considering the economic attributes of the emergency industry and the uncertainty characteristics of market returns, this study constructs an evolutionary game model for collaborative innovation among emergency enterprises, universities and research institutions (UR), and government departments, which are the main entities considered. It analyzes the evolutionary process of the strategy choices and equilibrium states of different entities, thereby revealing the key factors and intrinsic mechanisms affecting collaborative innovation pathways.
