Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Formation of an Optically Thick Shocked Shell in the Very Fast Nova V1674 Herculis: The Origin of Superbrightness

The Astrophysical Journal
V1674 Her is the fastest ( t _2 ∼ 1 day) classical nova in our Galaxy, and its absolute V peak of ${M}_{V,{\rm{\max }}}\sim -10.2$ is 1 mag brighter than typical very fast novae. Such a nova is sometimes called a superbright nova.

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion

Advanced Materials, EarlyView.
This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

Observations and simulations of recurrent novae: U Sco and V394 CrA [PDF]

, 1988
Observations and analysis of the Aug. 1987 outburst of the recurrent nova V394 CrA are presented. This nova is extremely fast and its outburst characteristics closely resemble those of the recurrent nova U Sco.

Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors

Advanced Materials Interfaces, EarlyView.
ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.

A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii

The Astrophysical Journal
A near-infrared spectrum of nova V1716 Scorpii (PNV J17224490-4137160), a recent bright ( ${V}_{\max }=7.3$ mag), Fermi-LAT detected γ -ray source, was modeled using the photoionization code CLOUDY.

Archival Gravitational-Wave Optical Transient Observer Photometry and Zwicky Transient Facility Localization of Galactic Novae: Quiescent Constraints and Improved Coordinates

Universe
We present archival photometry from the Gravitational-wave Optical Transient Observer (GOTO) for four Galactic novae discovered between 2017 and 2024, spanning some of the faintest ZTF24aaomlxy and PGIR22akgylf (at a marginal near-limit level consistent ...

A Multiwavelength Light-curve Model of the Classical Nova V339 Del: A Mechanism for the Coexistence of Dust Dip and Supersoft X-Rays

The Astrophysical Journal
The classical nova V339 Del 2013 is characterized by a 1.5 mag dip of the V light curve owing to a dust shell formation, with which soft X-ray emissions coexist.
