Electrical conductivity and Raman imaging of double wall carbon nanotubes in a polymer matrix [PDF]

, 2011
Raman spectroscopy is used to access the dispersion state of DWNTs in a PEEK polymer matrix. The interaction of the outer tube with the matrix can be determined from the line shape of the Raman G band.

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

Coordination‐Modulated Catalytic Pathways at Carbon Dots‐Supported Single‐Atom Sites Revealed by Thiol Interactions

Advanced Functional Materials, EarlyView.
Carbon dots‐supported single‐atom catalysts provide a model platform for uncovering how coordination interactions regulate catalytic reactivity. Thiol binding at Ru‒N4 centers reshapes the reaction energy landscape of H2O2 activation, dynamically modulating ROS‐generation pathways through electronic‐structure perturbation.

Water Organization and Hydration‐Dependent Hydroxide Transport in Anion Exchange Membranes (AEM)

Advanced Functional Materials, EarlyView.
Hydroxide transport in anion exchange membranes is governed by the organization of water within the polymer rather than by hydration alone. A hydration‐window framework is presented to unify transport, swelling, and mechanical stability, providing guidance for designing durable membranes for fuel cells and other hydroxide‐based electrochemical ...
