Electrochemical Determination of the Ionization Energy and the Electron Affinity of Lead Halide Perovskite Thin Films: A Comparison to Ultraviolet Photoelectron Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Benchmarking cyclic voltammetry (CV), electrochemical voltage spectroscopy (EVS), and ultraviolet photoelectron spectroscopy (UPS), complemented by photothermal deflection spectroscopy (PDS), provides practical guidance for halide perovskite energy‐level studies. Strategies for consistent onset determination across techniques are additionally addressed.

Infrared Irradiation‐Assisted Sonogashira Cross‐Coupling Reaction

open access: yesChemSusChem, Volume 19, Issue 17, 14 September 2026.
The Pd‐catalyzed Sonogashira cross‐coupling was developed under sustainable conditions using IR irradiation in water and a recyclable Pd/C catalyst. The protocol promotes efficient C(sp2)─C(sp) bond formation under mild conditions with low Pd loading (1 mol%), providing good to excellent yields for various aryl iodides and terminal alkynes.

Polarimetric Measures in Biomass Change Prediction Using ALOS-2 PALSAR-2 Data

open access: yesRemote Sensing
The use of multiple synthetic aperture radar polarizations can improve biomass estimations compared to using a single polarization. In this study, we compared predictions of aboveground biomass change from ALOS-2 PALSAR-2 backscatter using linear ...
