Conformational Fixation and Experimentally Guided Modeling of Excited‐State Relaxation in 3‐Morpholino Propenylidene Indolone Merocyanines

Aggregate, Volume 7, Issue 11, November 2026.
Conformational fixation of donor–acceptor merocyanines modulates excited‐state relaxation and fluorescence. Viscosity‐ and aggregation‐dependent emission, combined with TDDFT calculations, reveal a strongly twisted charge‐separated state in solution and a torsionally constrained emissive state in rigid environments, establishing a unified picture of ...

FTIR spectroscopy of conformational probes introduced into fullerene-containing branched poly (methyl methacrylate)

, 2020
In this paper we consider the effect of fullerene on the local molecular dynamics of the branched poly (methylmethacrylates). The temperatures of the secondary relaxation transitions were determined by FTIR spectra.

Assessing the microstructure of simple rhamphothecae in chickens (Aves: Galliformes: Gallus gallus domesticus)

Journal of Anatomy, Volume 249, Issue 5, Page 1099-1111, November 2026.
Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

A Terminal Carbazole Fused Ladder‐Type B,N‐Doped Multiresonant Thermally Activated Delayed Fluorescence Emitter: A Strategy for Deep‐Blue Emission

ChemistryEurope, Volume 4, Issue 10, October 2026.
Peripheral fusion of the boron/nitrogen (B/N)‐containing skeleton rigidifies the ladder‐type π‐extended framework of the literature compound α‐3BNMes, enabling precise control over its electronic and photophysical properties. The resulting emitter, B3N3, containing terminal annelated carbazole groups, exhibits a blueshifted, narrower emission spectrum,

Al2O3 Ring Array by Infiltration Synthesis in Polystyrene Antidot Template

Advanced Materials Interfaces, Volume 13, Issue 17, 8 September 2026.
Different morphologies, such as full dots for genuine PS‐b‐PMMA, residual dots for the PS antidot array (resulting from an Acetic Acid (AA) last PS‐b‐PMMA), and rings for the modified PS antidot array (derived from an O2 plasma last PS‐b‐PMMA), originated from SIS process in PS‐b‐PMMA BCP array, due to the different reaction sites for the TMA precursor

Optical Forces on Dielectric Microparticles: Exploring Size, Refractive Index, and Surface Charge Dependencies

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
This work systematically investigates the roles of particle size, refractive index, and surface charge in optical trapping. Calibrated force measurements combined with Mie theory calculations identify refractive index as the dominant factor governing trapping efficiency and reveal a correlation between ζ$$ \zeta $$‐potential and the phenomenological ...
