Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

open access: yesAdvanced Materials, Volume 38, Issue 37, 2 July 2026.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

The Centre of Attention: A Powerful Radio Galaxy Pinpoints a Near-infrared-dark Protocluster at z ∼ 3.9

open access: yesThe Astrophysical Journal
We report the discovery of a z ∼ 3.9 protocluster identified from Atacama Large Millimeter/submillimeter Array Band 3 spectral scans of a bright radio source selected from the Galactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey ...

Driver behind the bimodal distribution of Eddington-scaled radio luminosity in nearby early-type galaxies

open access: yesAstronomy & Astrophysics
Context. Early-type galaxies host low-luminosity active galactic nuclei, as indicated by radio emission spanning up to several orders of magnitude in terms of the physical scale, ranging from compact parsec-scale to extended kiloparsec-scale radio ...

Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition

open access: yesChemistry–Methods, Volume 6, Issue 7, July 2026.
We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

Radio Diagnostics Of Galaxy Interactions [PDF]

open access: yesSymposium - International Astronomical Union, 1999
The Hickson Compact Groups (Hickson 1982) are relatively isolated systems of galaxies with projected separations comparable to the diameters of the galaxies themselves and are an ideal laboratory for the study of the effects of interactions on the various properties of galaxies.

Identification of 4876 Bent-tail Radio Galaxies in the FIRST Survey Using Deep Learning Combined with Visual Inspection

open access: yesThe Astrophysical Journal Supplement Series
Bent-tail radio galaxies (BTRGs) are characterized by bent radio lobes. This unique shape is mainly caused by the movement of the galaxy within a cluster, during which the radio jets are deflected by the intracluster medium.

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...
