Modulating Electronic Structure of Atomic Iron Catalyst by Metallic Cobalt Cooperation for Boosting Oxygen Reduction/Evolution Reactions in Rechargeable and Flexible Zinc‐Air Battery

Carbon Energy, EarlyView.
Porous Co,Fe@NCNF‐900 catalyst has been innovatively synthesized as enhanced bifunctional catalysts by modulating the electronic structure of the atomic Fe catalyst through metallic Co cooperation. DFT analysis indicates that metallic Co as an electron donor can induce electron redistribution of the atomic Fe catalyst, thereby reducing the rate ...

Sculpting of Exoplanetary Systems Driven by a Misaligned Disk and Stellar Oblateness: Origin of Perpendicular Orbits in HD 3167

The Astrophysical Journal Letters
A significant proportion of exoplanets have been detected with highly tilted or even polar orbits relative to their host stars’ equatorial planes. These unusual orbital configurations are often linked to postdisk secular interactions among multiple ...

Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

Carbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

Bifurcated Evolutionary Pathways in Multiplanet Systems Driven by Misaligned Protoplanetary Disks

The Astrophysical Journal Letters
Stellar obliquities, or spin–orbit angles, prevalent in exoplanet systems, can impose important constraints on their formation and evolution histories.

Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments

Astronomy & Astrophysics
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems.

Strongly‐Anchored Ionomer‐Free Anode Catalyst Layer Fabricated via Joule Heating Achieves Efficient Electron/Mass Transfer for Acidic Water Electrolysis

Carbon Energy, EarlyView.
An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.

Resonant Chains and the Convergent Migration of Planets in Protoplanetary Disks

The Astronomical Journal
An increasing number of compact planetary systems with multiple planets in a resonant chain have been detected. The resonant chain must be maintained by convergent migration of the planets due to planet–disk interactions if it is formed before the ...

Excitation of planetary inclinations via dynamical bifurcations driven by misaligned disks

Astronomy & Astrophysics
Context. Primordial misalignments between protoplanetary disks and their host stars’ spin axes have been proposed to be important origins of the widespread stellar obliquities observed in exoplanets. Recent works have further revealed nontrivial and rich

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...
