Small, EarlyView.Direct injection synthesis with short‐chain decylammonium iodide produces uniform FAPbI3 perovskite nanocubes through isotropic growth and surface passivation. The resulting films show reduced defect‐mediated recombination, improved phase stability, and efficient charge transport.

Ultrafast Coherent Phonon Dynamics in GeTe and GeSe: Contrasting Metavalent and Covalent Bonding
Small, EarlyView.Ultrafast laser measurements reveal the differences in the optical response of atomic vibrations in GeTe and GeSe thin films. While crystalline GeTe exhibits strong, highly excitation‐sensitive coherent vibrations linked to metavalent bonding, covalently bonded GeSe shows weak or absent coherent phonons.

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.A highly electron‑accepting derivative of cyclobisbiphenylenecarbonyl (CBBC‐TIC) is reported. CBBC‐TIC functions as an electron‐transport layer for perovskite solar cells, achieving a power conversion efficiency of 20.6%. Furthermore, the enantiomers of CBBC‐TIC exhibited spin‐selective electron transport with high enantiospecific magnetic conductance ...

Small Methods, EarlyView.Microspectroscopy combines a standard optical microscope with a spectrometer to measure reflectance and transmittance of samples down to the microscale. A numerical formalism that explicitly accounts for the high numerical aperture of magnifying optics retrieves complex refractive indices.

Surface and Interface Analysis, Volume 58, Issue 12, Page 1071-1080, December 2026.ABSTRACT Hydration structures govern the properties and functions of hydrogels, yet selectively measuring hydration water in the presence of abundant bulk water remains analytically challenging. Here we applied pressure‐controlled attenuated total reflection infrared spectroscopy (ATR‐IR) combined with multivariate curve resolution (MCR) analysis, a ...

Advanced Materials, Volume 38, Issue 61, 2 November 2026.Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...
