Recurrent Novae, Classical Novae, Symbiotic Novae, and Population II Novae
, 2001 Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs.

International Astronomical Union Colloquium, 1988 AbstractSymbiotic Novae are composite spectrum variables, whose light history is characterized by a single nova-like outburst. Their behaviour and time evolution is rather similar to that of classical novae, except for the much longer time scale, and the associated physics could be the same.

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame
Advanced Functional Materials, EarlyView.High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Novas histórias, novas personagens
Revista de Estudos Literários, 2022 Uma das possiblidades de sobrevida da personagem, na perspectiva de uma teoria da figuração, projetada pelo crítico Carlos Reis, é a sua incorporação a uma narrativa subsequente àquela em que foi originalmente construída. A mulher do médico, por exemplo, é concebida na célebre obra Ensaio sobre a cegueira, de José Saramago, e refigurada como personagem

Advanced Healthcare Materials, EarlyView.ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

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

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

International Astronomical Union Colloquium, 1990 AbstractThermonuclear models of recurrent novae demand white dwarf accretors near the Chandrasekhar mass. In this case, the known recurrent novae should possess classical counterparts bearing the same structural parameters and space distribution, save for having only marginally less massive white dwarfs.
