Dual‐Site Ru Single‐Atoms and RuP Nanoclusters on N, P, and B Co‐Doped Porous Carbon for Efficient Alkaline HER and AEM Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Ru single atoms and RuP nanoclusters are co‐anchored in N, P, and B co‐doped porous carbon nanospheres via in situ carbonization/phosphidation of a boronate polymer precursor. RuP activates water, while nearby Ru single atoms accelerate H2 formation through H* transfer. The catalyst delivers low overpotential and high durability in alkaline HER and AEM

Laser Engineering of HfN‐Based Nanoparticles for Safe NIR‐I Photothermal and X‐ray Enhancing Cancer Therapies

open access: yesAdvanced Functional Materials, EarlyView.
In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

Atomic‐Level Ionic Displacement Polarization Enhanced Piezocatalytic Hydrogen Evolution in Covalent Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Two isomorphic COFs were synthesized and compared, including an amphoteric COF (SQ‐TAPT) and a neutral COF (PDA‐TAPT). The ionic bonds in SQ‐TAPT introduce more Born effective charges, thereby enhancing its ionic displacement polarization. Experimental and theoretical calculations demonstrated that SQ‐TAPT exhibited higher polarity and stronger ...

Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.
