Siloxane‐Functionalized Silicon Phthalocyanine OTFTs: High Hole Mobility and Unexpected p‐Type Character

open access: yesAdvanced Functional Materials, EarlyView.
In this paper, the first use of a siloxane‐substituted silicon phthalocyanine (iso(Si3O)2SiPc) in OTFTs is reported. Moreover, this compound displays the highest hole mobility (exceeding 1 cm2 V−1 s−1) ever recorded for SiPc, and the GIWAXS study reveals thin films with an exceptionally uniform crystalline texture.

Search for the Optical Counterpart of Einstein Probe–discovered Fast X-Ray Transients from the Lulin Observatory

open access: yesThe Astrophysical Journal Supplement Series
The launch of the Einstein probe (EP) mission has revolutionized the detection and follow-up observations of fast X-ray transients (FXTs) by providing prompt and timely access to their precise localizations.

Thermal Phase‐Modulation of Thickness‐Dependent CVD‐Grown 2D In2Se3

open access: yesAdvanced Functional Materials, EarlyView.
A comprehensive study of CVD‐grown 2D In2Se3 reveals a distinct thickness‐dependent phase landscape and a reversible, thermally driven transformation between β″ and β* variants. In situ TEM electron diffraction and Raman spectroscopy reveal structural dynamics, while the structural invariance of the α‐phase in ultrathin regimes highlights its stability—

GRB 221009A: Observations with LST-1 of CTAO and Implications for Structured Jets in Long Gamma-Ray Bursts

open access: yesThe Astrophysical Journal Letters
GRB 221009A is the brightest gamma-ray burst (GRB) observed to date. Extensive observations of its afterglow emission across the electromagnetic spectrum were performed, providing the first strong evidence of a jet with a nontrivial angular structure in ...

Ultrafast Adhesion/Friction Bidirectionally Switchable Control by Vibration

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired gradient smooth architectures enable vibration‐switchable adhesion/friction with 62.02 kPa adhesion strength, 131.57 kPa shear strength, tilt angles ≥ 3°, roughness ≥ Ra 0.8 µm, 400 Hz antivibration robustness, and dual‐mode control. The synergy of geometry optimization and vibration modulation tuning bridges multidomain adaptability and ...

The Redshift Distribution of Einstein Probe Transients Supports Their Relation to Gamma-Ray Bursts

open access: yesThe Astrophysical Journal Letters
The launch of the Einstein Probe unleashed a new era of high-energy transient discovery in the largely unexplored soft X-ray band. The Einstein Probe has detected a significant number of fast X-ray transients that display no gamma-ray emission ...
