Abstract

Tungsten and its alloys, due to their excellent high-temperature performance, radiation resistance, and mechanical properties, have become ideal candidate materials for key components in nuclear fusion reactors. This paper reviews the progress of research on the application of tungsten and tungsten alloys in the field of nuclear fusion, focusing on their performance in plasma-material interactions, heat load tolerance, and radiation damage. By analyzing current research results and technical challenges, this paper proposes future research directions and development trends, providing a reference for promoting the application of tungsten and tungsten alloys in the field of nuclear fusion.

Tungsten diiodide clusters can be used as X-ray contrast agents in interventional radiology. Tungsten diiodide cluster is a general term for a certain number of tungsten diiodide atoms or molecules, with a high degree of photoluminescence, this property makes it an excellent material for X-ray contrast agents.

Tungsten diiodide clusters are used as photosensitizers in photodynamic therapy. 

Tungsten diiodide molecules and clusters differ in structure and interaction force.
