Dielectric‐Confinement‐Induced in‐Plane Photoelectric Anisotropy in Isotropic Quasi‐1D γ‐GaS Nanoribbon

Advanced Science, Volume 13, Issue 45, 13 August 2026.
We investigate the geometry‐governed optoelectronic anisotropy arising from dielectric confinement in quasi‐1D γ‐GaS nanoribbons with intrinsically isotropic atomic structures. Dielectric mismatch between the nanoribbon and its surroundings leads to a general polarization‐dependent photoresponse during near‐field scattering.

Bright and Durable Copper‐Iodide‐Based Nanowire Scintillators

Aggregate, Volume 7, Issue 8, August 2026.
A surface‐protective‐agent (SPA)‐coordinated low‐temperature crystallization strategy regulates the surface microenvironment of CsCu2I3 nanowires at the atomic level. The SPA simultaneously suppresses iodine‐vacancy‐related defects and nonradiative recombination while eliminating Cu2+ species and surface oxide formation, offering a coherent pathway to ...

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Giant Phonon‐Enhanced Terahertz Electro‐Optic Response in Ferroelectric van der Waals NbOX2 (X = Br, I)

Laser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
Van der Waals ferroelectric NbOX2 thin films exhibit phonon‐resonance enhanced electro‐optic responses, 332 pm/V at 3.1 THz (NbOI2) and 192 pm/V at 3.7 THz (NbOBr2), the highest among vdW materials, and show 4% non‐resonant SHG modulation together with resonant phonon‐enhancement under a 150 kV/cm THz pump.

Feasibility of convection‐enhanced delivery of unlabeled 225Ac for glioblastoma: Transport, dosimetry, and clonogenic survival modeling

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Glioblastoma (GB) is an aggressive primary brain tumor with local recurrence rates exceeding 90% and a five‐year survival rate of approximately 5%. Standard treatments such as surgical resection, external beam radiotherapy (EBRT), and chemotherapy often leave residual tumor cells that are resistant to therapy.
