Defect‐Cascades‐Induced Photodegradation in InP/ZnSe/ZnS Quantum Dots

Advanced Science, Volume 13, Issue 4, 19 January 2026.
Surface sulfur vacancies in InP/ZnSe/ZnS quantum dots trigger vacancy cascades under blue light, propagating toward the ZnSe interface. In situ ESR (g = 2.004, 2.012) and DFT reveal a defect‐driven shift from type‐I to type‐II band alignment, reducing radiative recombination and EQE.

Qualitative Comparison of LED and LASER Effects on Cutaneous Wound Healing: A Systematic Review of Experimental Studies

Cell Biochemistry and Function, Volume 44, Issue 1, January 2026.
ABSTRACT This systematic review presents qualitative comparisons between LED and LASER photobiomodulation in cutaneous wound healing, limited by the substantial heterogeneity of experimental parameters. Chronic wounds represent a major clinical challenge due to prolonged healing times, high risk of infection, and increased healthcare costs ...

Integrated polarisation handling devices

IET Optoelectronics, 2020
Photonic integrated circuits (PICs) suffer from birefringence due to high‐index contrast. Polarisation handling devices improve the performance of the PICs by reducing the polarisation‐dependent dispersion and loss.

Surface Dynamics of Clean and Oxygenated InP(001) Surfaces in Contact with Water—Insights from Computational Spectroscopy

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Optical fingerprints of the electrochemical interface allow to correlate dynamic surface fluctuations to the electronic structure of oxidized InP(001). Ab initio molecular dynamics (AIMD) coupled with reflection anisotropy spectroscopy (RAS) helps in uncovering distinct spectral features related to surface reconstruction, hydroxylation, and solvent ...
