Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

Advanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Thermonuclear Superburst of MAXI J1752−457 Observed with NinjaSat and MAXI

The Astrophysical Journal Letters
An uncatalogued bright X-ray transient was detected with MAXI on 2024 November 9, named MAXI J1752−457. The NinjaSat X-ray observatory promptly observed the source from November 10 to 18, while the small angular separation from the Sun hampered follow-up

High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite

Advanced Functional Materials, EarlyView.
This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Long-term Evolution of Sco X-1: Implications for the Current Spin Frequency and Ellipticity of the Neutron Star

The Astrophysical Journal
Sco X-1 is the brightest observed extrasolar X-ray source, which is a neutron star (NS) low-mass X-ray binary (LMXB) and is thought to have a strong potential for continuous gravitational waves (CW) detection due to its high accretion rate and relative ...

Dual Side Chain Functionalization of Small Molecule Acceptors Affords High‐Performance Organic Solar Cells With Refined Blend Morphology

Advanced Functional Materials, EarlyView.
A new small‐molecule acceptor (SMA‐Ph‐CF3) is developed using a dual side chain functionalization strategy that incorporates trifluoromethyl and phenyl groups. This approach enables precise tuning of blend morphology, leading to the fabrication of high‐performance organic solar cells with a power conversion efficiency of 18.5%.

X-Ray Polarimetry of the Dipping Accreting Neutron Star 4U 1624–49

The Astrophysical Journal
We present the first X-ray polarimetric study of the dipping accreting neutron star 4U 1624−49 with the Imaging X-ray Polarimetry Explorer. We report a detection of polarization in the nondip time intervals with a confidence level of 99.99%.
