Locking Ni Atoms in Ordered PtNi for Durable Hydrogen Production: From Electrocatalyst Design to Practical AEMWE Stack Validation

open access: yesCarbon Energy, EarlyView.
DFT‐guided atomic ordering of PtNi intermetallic catalysts enhances HER activity and durability by optimizing hydrogen adsorption and increasing dissolution potential. Experimental validation from half‐cell to practical AEMWE stack demonstrates outstanding performance with less than 2% degradation over 3,000 h.

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

open access: yesCarbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and

Interplay of Bridge Topology and Conformation in Phenylene‐Bridged Trityl Diradicals

open access: yesChemistry – A European Journal, EarlyView.
We present a meta‐phenylene‐bridged trityl diradical that exhibits an unexpectedly weak antiferromagnetic exchange coupling J with a strong environment‐dependent magnitude. Combined VSM, EPR, DFT, and MD studies reveal that structural flexibility modulates σ‐, π‐, and through‐space exchange contributions, highlighting the crucial role of geometry in ...

Photothermal bubble: Dynamics, manipulation, and applications

open access: yesDroplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...

Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.
