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.

The First Orbital Period of a Very Bright and Fast Nova in M31: M31N 2013-01b [PDF]
The Astrophysical Journal, 2018 Abstract We present the first X-ray and UV/optical observations of a very bright and fast nova in the disk of M31, M31N 2013-01b. The nova reached a peak magnitude R ∼ 15 mag and decayed by 2 mag in only 3 days, making it one of the brightest and fastest novae ever detected in Andromeda.

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 ...

A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii
The Astrophysical JournalA 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.

A Very-High-Energy Gamma-Ray View of the Transient Sky
UniverseThe development of the latest generation of Imaging Atmospheric Cherenkov Telescopes (IACTs) over recent decades has led to the discovery of new extreme astrophysical phenomena in the very-high-energy (VHE, E > 100 GeV) gamma-ray regime.

Probing Strong Gravitational Fields in X-ray Novae
, 1998 Most X-ray novae (aka soft X-ray transients) contain black hole primaries. In particular, the large mass functions measured for six X-ray novae directly clinch the argument (within general relativity) that they contain black holes.

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

Advanced Materials, EarlyView.This study demonstrates a monolithic perovskite OELG device that performs all eight logic operations, including XOR and XNOR, without external bias. Enabled by trap‐engineered MAPbI3:PLL and dual photogates, it achieves reconfigurable logic and parallel decoding of amplitude–frequency signals, supporting scenario‐configured logic‐level separation for ...
