Entanglement enabled intensity interferometry in ultrarelativistic ultraperipheral nuclear collisions

Physical Review Research
An important tool in studying the subfemtoscale spacetime structure of matter in ultrarelativistic heavy-ion collisions is Hanbury Brown–Twiss (HBT) intensity interferometry of identical particles in the final state of the collisions.

Enhancing Grayscale E‐Beam Lithography: Thermal Treatment of Novolak‐Based Resist for 3D Nanostructures

Advanced Materials Interfaces, EarlyView.
Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible

Incorporating Heavy Atom Effect onto Molecular Rotors for Realizing Exceptionally Photocatalytic Oxidation Reaction under Low‐Temperature Conditions

Advanced Materials Interfaces, EarlyView.
Here, we reported a series of molecular‐rotor‐based photoactivated oxidase mimics, DAPy‐Xm, in which heavy atom incorporation enhances both ROS generation and cold‐adapted property. Among them, DAPy‐Im enables efficient photo‐oxidation of ergosterol and photocatalytic H2O2 production at low temperature.

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

Advanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

TADF‐Emitting Dendrimers for Scalable Bar‐Coating Fabrication of Light‐Emitting Electrochemical Cells

Advanced Materials Technologies, EarlyView.
TADF‐emitting dendrimers promise to enable scalable solution‐based fabrication of efficient electroluminescent devices by the virtue of an attractive set of properties. Here, we report on how light‐emitting electrochemical cells, comprising the TADF‐dendrimer tBuCz2m2pTRZ, can be fabricated by scalable bar‐coating under ambient air and deliver uniform ...

Zone‐Sectored Organic Crystals with Spatially Resolved Exciton Dynamics

Advanced Optical Materials, EarlyView.
Novel type of rubrene microcrystals in the orthorhombic phase are grown exhibiting spatial contrast in spectra and dynamics due to differences in unit cell orientation. Distinct zones selectively host redshifted luminescence band at ≈650 nm driven by high photon absorption.

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals

Advanced Optical Materials, EarlyView.
Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

Advanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.
