Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

The Synergism of β‐Cyclodextrin and Fe3+ Enabled Anti‐Swelling Ion‐Conductive Hydrogels for Multimodal Underwater Sensing Aided by Machine Learning Algorithms

Advanced Science, EarlyView.
An anti‐swelling ion‐conductive hydrogel is developed via β‐cyclodextrin and Fe3+ synergism, enabling reliable underwater motion sensing and Morse code communication. Integrated with machine learning, the system achieves 98.6% accuracy in real‐time underwater handwriting recognition for rapid information transmission.

Absorption of Millimeter-band CO and CN in the Early Universe: Molecular Clouds in the Radio Galaxy B2 0902+34 at Redshift 3.4

The Astrophysical Journal
Using the Karl G. Jansky Very Large Array, we have detected absorption lines due to carbon monoxide, CO( J = 0 → 1), and the cyano radical, CN( N = 0 → 1), associated with radio galaxy B2 0902+34 at redshift z = 3.4.

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence

Advanced Science, EarlyView.
A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...

Analyzing Polycyclic Aromatic Hydrocarbons as a Tracer of Anomalous Microwave Emission near the Galactic Plane Using the COSMOGLOBE DIRBE Reduction

The Astrophysical Journal
The physical mechanism producing anomalous microwave emission (AME) has been an unresolved puzzle for close to 30 yr. One candidate mechanism is rotational emission from polycyclic aromatic hydrocarbons (PAHs), which can have the necessary electric ...
