A Layered Two‐Dimensional Hydrogen‐Bonded Organic Framework Based on 2,5,8,11‐Tetrakis(4‐Carboxyphenyl)Perylene Diimide: Structural Nature, Optical and Photophysical Properties

open access: yesAdvanced Optical Materials, EarlyView.
A novel hydrogen‐bonded organic framework (HOF) based on perylene diimide (PDI) is synthesized, structurally and spectroscopically characterized. Its photophysical behavior highlights how supramolecular organizations govern the optical properties, including emission from monomers, aggregates, and excimer‐like species. Structural transformations induced

The Mg‐Fe Isotope Compositions and Geochemical Effects of Supercritical Fluids: Constraints From an Ultrahigh‐Pressure Eclogite‐Vein System in the Dabie Orogen

open access: yesGeochemistry, Geophysics, Geosystems
Supercritical fluids are ideal media for mass transfer from the subducting slab into the mantle wedge. However, little is known about the Mg‐Fe isotope compositions of supercritical fluids in subduction zones.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

open access: yesAdvanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
