First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Physics‐Informed Neural Networks for Modeling the Martian Induced Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Understanding the magnetic field environment around Mars and its response to upstream solar wind conditions provide key insights into the processes driving atmospheric ion escape. To date, global models of Martian induced magnetosphere have been exclusively physics‐based, relying on computationally intensive simulations. For the first time, we

A Third Star in the HAT-P-7 System and a New Dynamical Pathway to Misaligned Hot Jupiters

The Astrophysical Journal
The retrograde orbit of the hot Jupiter HAT-P-7b is suggestive of high-eccentricity (high-e) migration caused by dynamical interactions with a massive companion.

Hydride Nitrides: Crystal Structure Redetermination of LiSr2H2N and the Isostructural LiBa2H2N

European Journal of Inorganic Chemistry, Volume 29, Issue 16, 4 June 2026.
The quaternary hydride nitrides LiSr2H2N and LiBa2H2N are obtained in a non‐centrosymmetric crystal structure, different from previous reports. Crystal growth of the honey‐ and pale‐yellow compounds and essentially single phase synthesis is successful using alkali metal flux. The resulting fully ordered structures do not account for a structural reason

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Ultrafast Charge Carrier Dynamics in Layered CuO‐TiO2 Heterostructure via Time‐Resolved Soft X‐Ray Absorption Spectroscopy

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Schematic illustration of the carrier dynamics in the layered CuO∖TiO2 heterostructure. ABSTRACT Understanding the ultrafast carrier dynamics at the p‐n heterojunctions is indispensable for designing efficient photocatalysts. In this work, we used element‐specific time‐resolved soft X‐ray absorption spectroscopy (tr‐XAS) to investigate the ultrafast ...

Achieving Low Loadings yet Highly Active Catalysis by Ethylenediamine Promoted Dispersion of Palladium on Silica

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Uniform dispersion of low loadings of Pd nanoparticles on fumed silica was achieved using ethylenediamine (EN), resulting in highly stable and active catalytic propylene hydrogenation. ABSTRACT Deactivation of supported metal nanoparticles due to sintering is a key issue in industrial catalysts.

Semi‐Automated Platform for Early Prenatal Coelocentesis Testing Using Electrospun Nanofiber Technology

Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.
A semi‐automated approach for early prenatal diagnosis is developed for low‐cellularity samples from coelocentesis by exploiting biotin/streptavidin interaction to functionalize electrospun mats with antibodies. With potential microfluidic integration, the resulting platform enables fetal cell capture, offering a strategy toward improved efficiency and
