A Bridge between Young Stars Formed by Gravitational Interaction

The Astrophysical Journal Letters
The majority of stars are born in clustered environments. In these environments, close encounters between young stars with planet-forming disks are expected to occur frequently. However, direct evidence of such interactions remains rare.

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

Small, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

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.

A Multimodal In‐Situ Liquid Phase TEM and Electrochemical Study on Boric Acid as Electrolyte Additive for Alkaline Zinc‐Air Batteries

Small Methods, EarlyView.
This study establishes a multimodal correlative workflow to bridge disparate analytical scales in battery research. By linking dynamic in‐situ liquid‐phase TEM at the nanoscale with microscale morphological analysis and macroscale electrochemistry, a comprehensive mechanistic evaluation of electrolyte additives is achieved.

Discovery of Jet–Bubble–Disk Interaction: Jet Feedback on a Protoplanetary Disk Via an Expanding Bubble in WSB 52

The Astrophysical Journal
While stellar jets and outflows are fueled by accretion from disks, their direct influence on disks remain unexplored. Here, we revisit Atacama Large Millimeter/submillimeter Array observations of ^12 CO ( J  = 2–1) line emission for the young stellar ...

Microfluidic Molecular Diagnostic Chips: Functional Modules, Integration Strategies, and Emerging Applications

Small Methods, EarlyView.
This comprehensive review delivers an engineering‐centric analysis of microfluidic molecular diagnostic chips, breaking them down into foundational modules from fluid manipulation to bio‐sensing. Beyond chip design, it evaluates sample‐to‐answer integration strategies and commercial readiness levels.

Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.

Synthesis and Pd(II) Complexes of an Unsymmetric and Flexible Ferrocene Bisphosphine

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Insertion of flexible spacers into the pivotal C(ferrocene)P bonds in dppf increases flexibility of the resulting homologated ligands and lowers their tendency to coordinate as P,P′‐chelating ligands. To expand the family of flexible homologated analogs of 1,1′‐bis(diphenylphosphino)ferrocene, the unsymmetric bisphosphine 1‐(diphenylphosphino)‐1′‐[2 ...

The HR 8799 debris disk: Shaped by planetary migration and a possible fifth outermost planet

International audienceContext. The HR 8799 system hosts four giant planets between a warm and cold debris disk and has an extended dusty tail beyond. It serves as an ideal laboratory for studying planetary formation and evolution.

Adversarialism in the Family Courts in Child Arrangements Cases in England and Wales

The Modern Law Review, EarlyView.
Most of the discussion of adversarialism has taken place in the context of criminal justice and it is often assumed that family courts are not adversarial, particularly in child arrangements cases where the stated focus is the future welfare of children.
