One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐

Shaping Carbon Nitrides for Advanced Macrostructures
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Unprecedented 19 Day Type IV Radio Burst as a Corotating Electron Reservoir
We report a hectometric (0.5–3 MHz) type IV continuum observed over nearly 19 days (2025 August 21–September 9) in three successive visibility windows as the source corotates with the Sun—first at Solar Orbiter, then 12 days later in the near-Earth ...
