Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Constructing Ionic Fast Diffusion Channels on LiNi0.5Mn1.5O4 for Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐modification strategy is developed for LNMO cathode, where bulk Ti doping stabilizes the oxygen framework and simultaneously drives the in situ formation of LaTi2O6 nano‐islands as ion diffusion channels on (111) surfaces, enabling high‐rate capacity (∼100 mAh g−1 at 30 C) and excellent cycling retention (87.8% after 1000 cycles).

Investigation of Halogen Substitution Effects in π‐Conjugated Organic Ligands of Chiral Hybrid Perovskites on Their Chiroptical Activity

open access: yesAdvanced Functional Materials, EarlyView.
The role of novel thiophene‐based ligands with halogen substitutions in enhancing the chiroptical and optoelectronic properties of 2D chiral HOIPs has been investigated. By tailoring ligand design, enhanced CD and CPL properties are achieved, with improved CPL discrimination in photodetectors.

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Unlocking Multi‐Valley Energy Pockets and Interface‐Induced Phonon Filtering in InSb Thermoelectrics by Reaction‐Driven Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
InSb, a narrow‐bandgap semiconductor with high carrier mobility, is promising for thermoelectric energy conversion but suffers from high lattice thermal conductivity and strong bipolar conduction. Here, in situ interface engineering using Co2O3 nanoprecursors forms hierarchical CoSbx/In2O3/CoSb3 heterostructures that enhance phonon scattering and ...
