Migration of Accreting Planets and Black Holes in Disks

The Astrophysical Journal
Nascent planets are thought to lose angular momentum (AM) to the gaseous protoplanetary disk via gravitational interactions, leading to inward migration.

Planet-Planet gravitational scattering

, 2010
In planetary systems populated by two or more giant planets, planet--planet scattering can lead to collisions and ejections of one or more bodies. The original planetary configuration can be significantly altered by this kind of dynamical evolution and ...

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).

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.

Origin of the Asymmetric Gas Distribution near the Co-orbital Lagrange Points of an Embedded Planet

The Astrophysical Journal
Hydrodynamic simulations of planet–disk interactions often show material accumulation near the co-orbital Lagrange points L _4 and L _5 —features that may correspond to observed crescents in protoplanetary disks. Intriguingly, these simulations also show

The Disk Substructures at High Angular Resolution Project (DSHARP). VII. The Planet–Disk Interactions Interpretation

The Astrophysical Journal Letters, 2018
Abstract The Disk Substructures at High Angular Resolution Project (DSHARP) provides a large sample of protoplanetary disks with substructures that could be induced by young forming planets. To explore the properties of planets that may be responsible for these substructures, we systematically carry out a grid of ...

Regio‐Selective Electrocatalysis in Single‐Wall Carbon Nanotubes: Platinum Inside for Hydrogen Evolution Reaction/Hydrogen Oxidation Reaction and Ruthenium Outside for Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A Pt‐in/Ru‐out single‐wall carbon nanotube architecture spatially separates HER/HOR and OER active sites, enabling high HER/HOR currents at low overpotential, durable OER activity, and strong resistance to Fe3+ poisoning, offering a promising bifunctional platform for unitized regenerative fuel cells.

The Ophiuchus DIsk Survey Employing ALMA (ODISEA): A Unified Evolutionary Sequence of Planet-driven Substructures Explaining the Diversity of Disk Morphologies

The Astrophysical Journal Letters
Understanding the origin of substructures in protoplanetary disks and their connection to planet formation is currently one of the main challenges in astrophysics. While some disks appear smooth, most exhibit diverse substructures such as gaps, rings, or

Planet-Disk Interactions and Early Evolution of Planetary Systems [PDF]

, 2014
The great diversity of extrasolar planetary systems has challenged our understanding of how planets form, and how their orbits evolve as they form. Among the various processes that may account for this diversity, the gravitational interaction between planets and their parent protoplanetary disc plays a prominent role in shaping young planetary systems.

Cytoskeleton–Membrane Uncoupling in Duchenne Muscular Dystrophy: Implications for Newborn Screening and Early Protection

Cytoskeleton, EarlyView.
ABSTRACT The cytoskeleton of striated muscle integrates force transmission, mechanotransduction, and sarcolemmal stability through coordinated networks of sarcomeres, costameres, and intermediate filaments. Together, these systems establish mechanical continuity between the contractile apparatus, the sarcolemma, and the extracellular matrix.
