Organic AIE Nanoradiosensitizer Potentiates X‐Ray Triggered Continuous Reactive Oxygen Species Generation for Potent Cancer Radioimmunotherapy

Advanced Materials, EarlyView.
Herein, a glutathione‐responsive system (named THN) is prepared for X‐ray‐triggered sustained ROS generation for efficient antitumor immunotherapy. The double‐promoting ROS generation of THN induced massive immunogenic cancer cell death and polarized M2 macrophages into the M1 phenotype for enhanced antitumor immunotherapy.

Long-duration Gamma-Ray Burst Progenitors and Magnetar Formation

The Astrophysical Journal, 2023
Millisecond magnetars produced in the center of dying massive stars are one prominent model to power gamma-ray bursts (GRBs). However, their detailed nature remains a mystery. To explore the effects of the initial mass, rotation rate, wind mass loss, and

Remnants from Gamma-Ray Bursts

, 2000
We model the intermediate time evolution of a "jetted" gamma-ray burst by two blobs of matter colliding with the interstellar medium. We follow the hydrodynamical evolution of this system numerically and calculate the bremsstrahlung and synchrotron ...
