Microfluidic Gratings for X‐Ray Phase Contrast Imaging

Advanced Science, EarlyView.
This work establishes a new protocol for the fabrication of X‐ray gratings that exploits the advantages of microfluidics and enables a more inexpensive, faster, and scalable production process. These X‐ray devices are fundamental for implementing X‐ray phase contrast imaging (XPCI) in laboratory and clinical settings, yet their costly and complex ...

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

Advanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Crystallized Domain Walls in HfO2 Enable Chessboard‐Type Ultra‐High‐Dense Ferroelectric Memory

Advanced Science, EarlyView.
In general, DWs in ferroelectrics stabilize within a widely spread transition region between two oppositely polarized domains, which severely limits the achievable memory density. Here, the reported DWs in HfO2 constitute perfect crystalline structures along arbitrary crystallographic directions, enabling the formation of the narrowest square‐shaped ...
