The Long-Term Spectroscopic Misadventures of AG Dra with a Nod Toward V407 Cyg: Degenerates Behaving Badly

open access: yesOpen Astronomy, 2012
We present some results of an ongoing study of the long-term spectroscopic variations of AG Dra, a prototypical eruptive symbiotic system. We discuss the effects of the environment and orbital modulation in this system and some of the physical processes ...

Swift X-ray Observations of Classical Novae

open access: yes, 2007
The new gamma-ray burst mission Swift has obtained pointed observations of several classical novae in outburst. We analyzed all the observations of classical novae from the Swift archive up to 30 June, 2006.

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

open access: yesAdvanced 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 ...

Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae

open access: yes, 2009
We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications. In many systems, the evolution of superhump period are found to be composed of three distinct stages: early ...

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion

open access: yesAdvanced 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

A Cryoprotectant‐Compatible Nanoporous Platform for Stable and Scalable Delivery of Biopharmaceuticals

open access: yesAdvanced Materials, EarlyView.
A cryoprotectant‐compatible nanoporous platform enables ambient‐stable and scalable delivery of gene editing therapeutics. By combining hierarchical pore architecture with optimized lyophilization chemistry, the system preserves Cas9‐RNP activity post‐freeze‐drying.

Hybrid Liquid Metal Cathode Enables High‐Performance Intrinsically Stretchable OLEDs

open access: yesAdvanced Materials, EarlyView.
We report a hybrid liquid metal (Hyb‐LM) cathode engineered via selective rupture of liquid metal particles (LMPs), forming a bilayer architecture with a surface liquid metal (LM) layer and underlying LMP layer, which has benefits of both LM and LMPs.

Surface‐Capped Protein Nanoparticles for Nonviral Gene Delivery

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Developing simple, safe, and efficient nonviral delivery systems remains a significant challenge in bioengineering. Nanoparticles offer promising gene delivery capabilities with reduced toxicity; however, long‐standing challenges related to effective plasmid encapsulation and delivery exist.

Fully Self-consistent Nova Explosion Models Reproducing Light Curves of KT Eri, V339 Del, V597 Pup, and SMC NOVA 2016-10a

open access: yesThe Astrophysical Journal
The rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free–free emission model light curves based on our fully self-consistent nova explosion models, we present several theoretical light ...

Fermi-LAT detections of the classical novae V1723 Sco and V6598 Sgr in a multi-wavelength context

open access: yesAstronomy & Astrophysics
Context. Numerous classical novae have been observed to emit γ-rays (E > 100 MeV) detected by the Fermi-LAT. The prevailing hypothesis attributes this emission to the interaction of accelerated particles within shocks in the nova ejecta.
