Effects of Electrochemical Activation Methods on the Restructuring and Oxygen Reduction Performance of PtNix “Core–Shell” Carbon‐Nitride/Carbon Supported Electrocatalysts

open access: yesChemElectroChem, Volume 13, Issue 22, 17 November 2026.
Reversible‐potential‐sweep, constant‐potential, and constant‐current methods are applied in a flow‐through electrochemical cell to activate the precursor P. Extreme dealloying and nanorestructuring convert its coarse PtNi9–10 domains into Pt‐rich PtNix (x ≈ 0.3) nanoparticle nanoaggregates forming metal‐alloy “nanosponge‐like domains.” The recovered ...

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers
