Comparative Study of Photopolymerized Gel Polymer Electrolytes Obtained via Thiol‐Ene Click Reaction for Li Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 5, September 2025.
In the context of Li metal batteries, gel polymer electrolytes (GPEs) offer enhanced cell safety and the optimum compromise between mechanical and electrochemical properties. A thiol‐ene approach to the GPE production was employed, evaluating the effect of two different crosslinkers, as well as the crosslinking environment and the production method ...

Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Active Galactic Nuclei Feedback in SDSS-IV MaNGA: AGNs Have Suppressed Central Star Formation Rates

open access: yesThe Astrophysical Journal, 2023
Despite the importance of feedback from active galactic nuclei (AGNs) in models of galaxy evolution, observational constraints on the influence of AGN feedback on star formation remain weak.

Localized Thermoresponsive Behavior in P(NIPAm‐co‐AAc) Copolymers: Structural Insights From Rheology and Small Angle X‐Ray Scattering

open access: yesJournal of Polymer Science, Volume 63, Issue 2, Page 393-405, 15 January 2025.
ABSTRACT Stimuli‐responsive polymers stand out for their ability to respond to small environmental changes. One of the most representative thermo‐sensitive materials is poly(N‐isopropyl acrylamide) (PNIPAm), which presents reversible phase transitions close to the human body temperature.

ASYMPTOTIC STRUCTURE OF SIMPLE COSMOLOGICAL MODELS

open access: yesAnales (Asociación Física Argentina), 2013
The future null infinity for all non-contracting Robertson-Walker spacetimes is studied systematically. A theorem is proved which establishes the expected relation between the nature of g + and the appearance or absence of cosmic event horizons.

On the Love Numbers of an Andrade Planet

open access: yesEarth and Space Science, Volume 11, Issue 9, September 2024.
Abstract The Andrade rheological model is often employed to describe the response of solar system or extra‐solar planets to tidal perturbations, especially when their properties are still poorly constrained. While for uniform planets with steady‐state Maxwell rheology the analytical form of the Love numbers was established long ago, for the transient ...

Astronomía y matemáticas, un matrimonio fecundo [PDF]

open access: yes, 2010
La conexión establecida a lo largo de la historia entre las matemáticas y la astronomía, ha sido profunda y fructífera para ambas. Las dos ciencias se han beneficiado mutuamente de un intercambio constituido por la formulación de problemas interesantes ...
