High Pressure Densification Investigation of Li3PS4 and Li6PS5Cl Solid Electrolytes using Combine X‐Ray Diffraction, X‐Ray Absorption Tomography and Ionic Measurement

Advanced Functional Materials, EarlyView.
We used multiple analytical techniques at the Psiché beamline, Synchrotron Soleil, and at D20 instrument in Institut Laue Langevin, to study the densification of thiophosphate solid electrolytes Li3PS4 and Li6PS5Cl. Our combined X‐ray diffraction, absorption tomography, absorption density, neutron power diffraction, and ionic conductivity analyses ...

Multiwavelength ALMA Imaging of HD 34282: Dust-trapping Signatures of a Vortex Candidate

The Astrophysical Journal
Azimuthal arcs in millimeter continuum emission from protoplanetary disks are often attributed to dust-trapping vortices, but definitive observational confirmation of vortices remains lacking.

Reassessing late-stage impact assumptions in light of modern planet formation paradigms

Frontiers in Astronomy and Space Sciences
In this Perspective, we examine the implications of modern cold-accretion and disk-mediated paradigms for two widely cited impact hypotheses: the Moon-forming giant impact and the Late Heavy Bombardment, with attention to consequences for planetary ...

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

Advanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Chemistry of Complex Organic Molecules in the V883 Ori Disk Revealed by ALMA Band 3 Observations

The Astronomical Journal
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary disks remains poorly understood.

Planet formation constraints from exoplanet population synthesis and simulation based inference

Frontiers in Astronomy and Space Sciences
This work introduces a statistical framework to obtain Bayesian constraints on planet formation parameters, which offers a probabilistic interpretation of uncertainties and degeneracies contained within planet formation models.

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

Advanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

A mantle source formed after the lunar magma ocean crystallisation for the 3000 Ma-old lunar basalts

Communications Earth & Environment
There is no satisfactory model explaining the incompatible element-enriched chemical characteristics observed in few ~3000 Ma-old, low-titanium lunar basalts.

Terrestrial planet formation during giant planet formation and giant planet migration

Astronomy & Astrophysics
Context. Terrestrial planet formation (TPF) is a difficult problem that has vexed researchers for decades. Numerical models are only partially successful at reproducing the orbital architecture of the inner planets, but have generally not considered the effect of the growth of the giant planets.

Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids

Advanced Healthcare Materials, EarlyView.
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...
