Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Electrode state‐of‐charge heterogeneity critically limits lithium‐ion battery performance and safety. This Perspective highlights iSCAT, a powerful optical technique for real‐time, nanoscale visualization of lithium dynamics within single particles. By revealing the origins of heterogeneity, iSCAT enables rational electrode design.

The deactivation of CrOx/Al2O3 by two stages under PDH is revealed via in situ TEM. Initially, CrOx particles disperse and transform into AlxCryO solid solutions that promote graphitic coke growth. Subsequently, the continuous migration of Cr results in the formation of Cr‐rich solid solutions that only partially revert under oxidative regeneration ...

Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...
