Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

open access: yesAdvanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Detection of Hydrocarbons in the Disk around an Actively Accreting Planetary-mass Object

open access: yesThe Astrophysical Journal
We present the 0.6–12 μ m spectrum of Cha 1107-7626, a 6–10 Jupiter-mass free-floating object in the ∼2 Myr-old Chamaeleon-I star-forming region, from observations with the NIRSpec and MIRI instruments on board the James Webb Space Telescope.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

FORGE'd in FIRE III: The IMF in Quasar Accretion Disks from STARFORGE

open access: yesThe Open Journal of Astrophysics
Recently, we demonstrated self-consistent formation of strongly-magnetized quasar accretion disks (QADs) from cosmological radiation-magnetohydrodynamic-thermochemical galaxy-star formation simulations, including the full STARFORGE physics shown ...

The Formation of Brown Dwarfs: Observations

open access: yes, 2006
We review the current state of observational work on the formation of brown dwarfs, focusing on their initial mass function, velocity and spatial distributions at birth, multiplicity, accretion, and circumstellar disks.

From Fiber Architecture to Functional Attachment: A Clinically Relevant, Mechanically Tunable Cardiac Patch

open access: yesAdvanced Materials, EarlyView.
A personalizable platform featuring a multi‐zonal cardiac patch design at clinical scale enables precise customization of fiber architecture at micro‐ and macroscale via melt electrowriting. Distinct scaffold zones support cell alignment with mechanical force transfer and epicardial attachment.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

Testing Magnetospheric Accretion as an Hα Emission Mechanism of Embedded Giant Planets: The Case Study for the Disk Exhibiting Meridional Flow Around HD 163296

open access: yesThe Astronomical Journal
Recent high-sensitivity observations reveal that accreting giant planets embedded in their parental circumstellar disks can emit H α at their final formation stages.
