Pixelation‐Free, Monolithic Iontronic Pressure Sensors Enabling Large‐Area Simultaneous Pressure and Position Recognition via Machine Learning

Advanced Functional Materials, EarlyView.
A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...

Exploring the Maximum Magnitude versus Rate of Decline Relation for Novae in M31

The Astrophysical Journal Supplement Series
The results of a two-decade-long R -band photometric survey of novae in M31 are presented. From these data, R -band light curves have been determined for 180 novae with data sufficient for estimating the peak brightness and subsequent rate of decline ...

Effects of Molecular Designs and Double‐Network Morphologies for Bioadhesive Semiconductors

Advanced Functional Materials, EarlyView.
This study establishes molecular‐to‐mesoscale design rules for bioadhesive semiconducting polymers (BASCs). It identifies how side‐chain length, double‐network formation, and film thickness modulate adhesion strength and electronic performance, providing insight into the rational design of intrinsically adhesive semiconductors for stable and efficient ...

Medical Fabrics with Non‐Antibiotic, Supramolecular Antimicrobial Coatings: A Preventive Approach to Combat Biofilm Formation and Bacterial Dissemination

Advanced Healthcare Materials, EarlyView.
The study presents an antibiotic‐free strategy using medical fabrics coated with supramolecular assemblies of polyarginine and hyaluronic acid. These coatings showed strong antimicrobial and anti‐biofilm activity in vitro and in vivo, achieving major bacterial load reductions, including against MRSA.

Orbital Period Changes of Recurrent Nova U Scorpii Demonstrate That Mejecta = 26 × Maccreted, So U Sco Is Not a Type Ia Supernova Progenitor

The Astrophysical Journal
Recurrent nova U Scorpii (U Sco) is one of the prototypes for a Type Ia supernova progenitor. The logic is that the white dwarf is near the Chandrasekhar mass and gas is accumulating onto its surface at a near-maximal accretion rate, so it will soon ...

On the observability of recurrent nova super-remnants

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACTThe nova super-remnant (NSR) surrounding M 31N 2008-12a (12a), the annually erupting recurrent nova (RN), is the only known example of this phenomenon. As this structure has grown as a result of frequent eruptions from 12a, we might expect to see NSRs around other RNe; this would confirm the RN–NSR association and strengthen the connection ...

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

Advanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...

Recurrent Nova V2487 Oph Had Superflares in 1941 and 1942 with Radiant Energies of 1042.5±1.6 erg

The Astrophysical Journal
V2487 Ophiuchi (V2487 Oph) is a recurrent nova with classical nova eruptions in 1900 and 1998, and it is also the most extreme known superflare star. These superflares are roughly hour-long flares with amplitudes and optical energies reaching up to 1.10 ...

Recurrent Symbiotic Nova T Coronae Borealis before Outburst

Astronomy Letters, 2023
The results of photometric and spectral observations of T CrB obtained in a wide range of wavelengths in 2011–2023 are presented. We use the near-IR light curves to determine a new ephemeris JDmin=2455828,9+227,55E for the times of light minima when the red giant is located between the observer and the hot component. The flux ratio Ha/Hb varied from -3
