Spectrographic Analysis of Hafnium in Zirconium Oxide

Journal of the Spectroscopical Society of Japan, 1959
This method is devised for the determination of hafnium in zirconium oxide as reactor material.The“sifter electrode-spark excitation technique ” employed by C.Feldman and J.Y.Ellenburg is utilized and the sensitivity is extended to 100 ppm hafnium.In this technique, samples, finely ground and mixed with equal amount of graphite powder, are put into the

A Single‐Metal‐Doped Nanoplatform for Ferroptosis‐Driven cGAS‐STING Pathway Activation in Hepatocellular Carcinoma Immunotherapy

Advanced Functional Materials, EarlyView.
The cGAS‐STING pathway boosts HCC antitumor immunity but lacks specific activation. Nanoplatform ZMRPF induces HCC ferroptosis via lipid ROS, releasing mtDNA. It synergizes with ZMRPF‐released Mn2⁺ to activate cGAS‐STING, amplifies antigen‐presenting cell activity, reverses HCC immunosuppression, and enables robust systemic antitumor immunity ...
