Since September 2020, there have been several global supply chain attacks such as SolarWinds, Kaseya, NPM IconBurst, and Cyber Av3ngers Unitronics. Many of these incidents involved nation-state actors and resulted in significant disruptions and failures. In this threat landscape, the Department of Defense and critical infrastructure sectors have frequently and repeatedly come under attack, sustaining extensive damage.

Photothermal therapy is a new, promising approach for treating cancer in a non-invasive way. In this work, we synthesized a photothermally efficient nanomaterial, by exposing bulk WS2 powder, dispersed in carbon-rich acetonitrile, to high-intensity femtosecond laser pulses. The photothermal measurements showed a significantly higher rise in temperature and enhanced photothermal efficiency for the laser-treated material.
