Breaking Giant Chains: Early-stage Instabilities in Long-period Giant Planet Systems

The Astrophysical Journal
Orbital evolution is a critical process that sculpts planetary systems, particularly during their early stages where planet–disk interactions are expected to lead to the formation of resonant chains.

Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

Advanced Science, EarlyView.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

Microwave‐Driven Dielectric‐Magnetic Regulation of Graphite@α‐MnO2 Toward Enhanced Electromagnetic Wave Absorption

Advanced Science, EarlyView.
This study presents a microwave‐activated composite integrating expanded graphite with α‐MnO2 nanowires, engineered to synergistically optimize dielectric and magnetic properties. The innovative microwave‐driven process enables rapid structural transformation, yielding ultrathin, scalable electromagnetic wave‐absorbing films.

Formation of Giant Planets

Annual Review of Astronomy and Astrophysics
Gas giant planets, if present, are the most massive objects in a planetary system and play a pivotal role in shaping its overall architecture. The formation of these planets has constantly been a central issue in planetary science. Increasing evidence from spacecraft explorations of Jupiter and Saturn, as well as telescope observations of exoplanets ...

White dwarf planets

EPJ Web of Conferences, 2013
The recognition that planets may survive the late stages of stellar evolution, and the prospects for finding them around White Dwarfs, are growing. We discuss two aspects governing planetary survival through stellar evolution to the White Dwarf stage ...

Configuration and Charge Dynamics of Defect‐Cluster‐Dipoles in CaTiO3 for Enhanced Permittivity

Advanced Electronic Materials, EarlyView.
In La‐doped CaTiO3, the clustering of La ion and Ca vacancies is clearly observed and the configuration of such defect‐cluster is validated. Combining photoelctronic and dielectric spectroscopy enables the dielectric relaxation process with the charge transfer routes.
