Near‐Field Optical Nanopatterning of Graphene

open access: yesSmall Science, EarlyView.
Scattering‐type scanning near‐field optical microscopy‐driven near‐field optical nanopatterning of graphene is studied. 2D materials are emerging as transformative platforms for next‐generation memory, sensing, photonic, and quantum devices due to their extraordinary optical, mechanical, and electronic properties.

Experimental Kinetic Study of the Reactions of Hydroxyl Radicals With Three Oxymethylene Ethers and With 1,3,5‐Trioxane, Tetrahydrofuran, and Tetrahydrofuran‐d8

open access: yesInternational Journal of Chemical Kinetics, Volume 57, Issue 8, Page 497-506, August 2025.
ABSTRACT Polyoxymethylene dimethyl ethers, CH3O(CH2O)nCH3 with n ≥ 1 (abbreviated in the literature also as OME‐n, PODEn, POMDMEn, or OMDMEn) are currently discussed as renewable fuels. Despite fuel + OH reactions are crucial for the combustion chemistry and atmospheric degradation of fuels, experimental kinetic data on OME‐n + OH do not exist in the ...

Highly Off‐Centering Cations in Pavonite‐Structured Ag1.75InSb5.75Se11 with Competitive Thermoelectric Performance

open access: yesAdvanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping

Cooperativity of Electron Transfer Coupled Spin Transitions in a Tetranuclear Fe/Co Prussian Blue Analogue Revealed by Ultrafast Spectroscopy

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.
Ultrafast pump‐probe spectroscopies show that irradiation of a square Fe/Co Prussian blue analogue induces electron transfer within one Fe–Co subunit followed by fast spin crossover, and coupled equilibria between all states trigger a second electron transfer coupled to spin crossover in the other Fe–Co subunit on a ns timescale.

Design and Characterization of Mixed Ligand Mn (II) Complex With 4‐Iodo‐Pyridine‐2‐Carboxylic Acid for Enhanced Nonlinear Optical Applications: A Theoretical and Experimental Approach

open access: yesApplied Organometallic Chemistry, Volume 39, Issue 7, July 2025.
Mn (II) complex with 4‐iodo‐pyridine‐2‐carboxylic acid and 5,5′‐dimethyl‐2,2′‐bipyridine has shown significant potential for nonlinear optical (NLO) applications, as evidenced by both static and frequency‐dependent NLO analyses. This is attributed to the interaction between Mn (II) ion and the coordinated ligands, which facilitates intramolecular ...

Exploring the Interplay of Lattice Dynamics and Charge Transport in Organic Semiconductors: Progress Toward Rational Phonon Engineering

open access: yesAngewandte Chemie, Volume 137, Issue 26, June 24, 2025.
This Minireview highlights recent advances in understanding the role of lattice dynamics and electron–phonon coupling in organic semiconductors. Emphasis is placed on mode‐resolved insights into dynamics‐induced electronic disorder, emerging strategies for phonon engineering, and the implications of both low‐ and high‐frequency vibrations on charge ...
