Challenges and Opportunities in Machine Learning for Light‐Emitting Polymers

Macromolecular Rapid Communications, EarlyView.
The performance of light‐emitting polymers emerges from coupled effects of chemical diversity, morphology, and exciton dynamics across multiple length scales. This Perspective reviews recent design strategies and experimental challenges, and discusses how machine learning can unify descriptors, data, and modeling approaches to efficiently navigate ...

Room-Temperature Phosphorescence of Quinine Sulfate in PVA Films: The Effect of Humidity

Optics
We report the first observation of room-temperature phosphorescence (RTP) of quinine sulfate (QS) in poly (vinyl alcohol) (PVA) films. Steady-state and time-gated measurements were performed to characterize the phosphorescence spectra, anisotropies, and ...

Inter‐/Intramolecular π‐Stacking in a Benzannulated NCN‐Coordinated Pd(II) Monomer and Dimer Pair: Synthesis, Structure, and Photophysics

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A cyclometalallated palladium complex and its acetate‐bridged dinuclear analogue, both supported by 1,3‐bis(2‐quinolinyl)benzene ligands, are described. The mononuclear (but not the dinuclear) complex is weakly phosphorescent in the deep red region of the spectrum in solution at room temperature, and both compounds phosphoresce in frozen media at 77 K ...

Alloxazine derivatives as multifunctional agents for photodynamic therapy, cancer cell imaging, and cell proliferation inhibition

Photochemistry and Photobiology, EarlyView.
Alloxazine photosensitizers, molecularly engineered through sugar conjugation and methoxy substitution to enhance solubility, photodynamic potency, and fluorescence, enable image‐guided photodynamic therapy while inhibiting cancer cell growth in the absence of photoactivation.

Noradrenergic regulation of skeletal muscle oxygen pressures: Impact of heart failure with preserved ejection fraction and heat therapy

Experimental Physiology, EarlyView.
Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

Real‐Time Kinetic Monitoring of Dental Composite Photopolymerization by Photo‐DSC

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Real time photo‐DSC was used to investigate polymerization kinetics of Bis‐GMA/TEGDMA dental composites. The study thoroughly examines how photo‐initiator type, concentration, silica filler content, and moisture affect conversion and curing rate. Results highlight optimal initiator systems, filler effects, and moisture tolerance, providing valuable ...
