Redox‐Active Guanidines

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Computational Analysis of Chromophore‐Controlled Photoactivation in Monofunctional Platinum(II)–BODIPY Conjugates for Dual Chemo‐Photodynamic Therapy

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
BODIPY‐decorated monofunctional Pt(II) complexes were computationally designed as dual chemo‐photodynamic agents. π‐conjugation engineering shifts absorption into the therapeutic window (up to 661 nm) while preserving singlet oxygen generation and DNA platination capability.

Simultaneous Type‐0 and Type‐I Optical Parametric Oscillation in Submicron Poled Thin‐Film Lithium Niobate

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Backward optical parametric oscillation is realized in a submicron‐poled thin‐film lithium niobate microring. By engineering the quasi‐phase‐matching condition, both type‐0 and type‐I degenerate oscillation emerge in the same device and are selectively accessed through temperature tuning, providing a versatile on‐chip platform for polarization‐diverse ...

Optimum Cross‐Sections for Wurtzite‐Structure Nanowires From Analytic Thermodynamic and Crystallographic Arguments

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
Using the analytic cross‐section morphing of wurtzite nanowires to arbitrary shapes (König, Bian, Fu, and Smith, Adv. Theo. Simul. 2025, 8 2400951), the cross‐section shape with the maximum number of nanowire‐internal bonds per nanowire atom is derived, representing the most stable intrinsic crystalline form (structural‐thermodynamic optimum).

Luminescence Spectra Simulation of Ce3+‐Activated Phosphors by Accumulating Emission Lines Along First‐Principles Molecular Dynamics Trajectories

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
A density functional theory‐based method is introduced to predict the luminescence emission spectra of candidate compounds, including broadening caused by atomic thermal motion. For each snapshot from the molecular dynamics of the Ce‐activated system using the excited‐state electron configuration, the transition energies and probabilities are ...
