Electrochemically Driven Dissipative Growth of Affinity Hydrogels for Bioresponsive Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Voltage pulses drive the growth and reinforcement of hydrogel films under dissipative conditions. This biocompatible strategy enables efficient integration of affinity ligands into the hydrogel matrix, enhancing the selective capture of growth factors and allowing precise temporal control over their release, making them well‐suited as adaptive ...

CHIME/FRB Discovery and Localization of the Swift-observed FRB 20241228A

open access: yesThe Astrophysical Journal
On 2024 December 28, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project detected the thus-far nonrepeating FRB 20241228A with a real-time signal-to-noise ratio of >50.

Viscoelasticity‐Induced Controllable Periodic Meso‐Textures of Liquid Crystal Polymers in Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
Viscoelasticity‐driven instabilities are harnessed to create tunable, periodic textures in 3D‐printed liquid crystalline polymers. This study illustrates how processing parameters control these spontaneous meso‐scale patterns. These unique structural architectures unlock new possibilities for functional devices, ranging from photonic components to ...

The Impact of Accretion on FRB Radiation Mechanisms in Binary Systems: Constraints and Implications

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) are intense, millisecond-duration radio transients that have recently been proposed to arise from coherent radiation mechanisms within the magnetosphere of neutron stars.

Jet induced star formation in centrally dominant galaxies? [PDF]

open access: yes
Using U-I CCD color maps of two centrally dominant cluster galaxies, we find unusual color structures which may be due to star formation which has been induced by their radio sources.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

open access: yesAdvanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Constraints on Evolutions of Fundamental Constants from Clustering of Fast Radio Burst Dispersion Measure

open access: yesThe Astrophysical Journal
Constrained measurements of fundamental physical constants using astronomical observational data represent a powerful method for investigating potential new physics. In particular, the dispersion measure (DM) of fast radio bursts (FRBs), which probes the

Coexisting Rashba/Dresselhaus Spin Splitting in Solution‐Processed Bournonite Films Using Circular Photogalvanic Effect

open access: yesAdvanced Functional Materials, EarlyView.
Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Can Repeating and Nonrepeating Fast Radio Bursts Be Drawn from the Same Population?

open access: yesThe Astrophysical Journal
Do all fast radio burst (FRB) sources repeat? We present evidence that FRB sources follow a Zipf-like distribution, in which the number density of sources is approximately inversely proportional to their burst rate above a fixed energy threshold—even ...
