Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

Advanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

Advanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

Advanced Materials Interfaces, EarlyView.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between
