Advancing Direct Alcohol Fuel Cells: Innovations in Composite‐Based Electrocatalysts and Polymer Support Materials for Enhanced Efficiency

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.
This graphical abstract emphasizes the working principle and the various essential factors of the direct methanol fuel cell (DMFCs). Additionally, various parameters, such as the nanoparticle's size and shape, the nature of the electrolyte, the type of support materials, and their fabrication process, also play essential roles in the functioning of the

Discovery of Evolution of the Temporal Features of X-Ray Bursts from SGR J1935+2154

open access: yesThe Astrophysical Journal
SGR J1935+2154 has undergone eight active episodes since its discovery in 2014. In this study, our focus is on the evolution of the temporal characteristics including burst duration, minimum variation timescale (MVT), and waiting time across these active

An Accessible Large‐Language‐Model‐Based Framework for Power Converter Design

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article proposes an LLM‐based autonomous design framework that incorporates a universal circuit‐encoding method for power converter design and verification, delivering high scalability across diverse scenarios. The most dominant feature of the work is that all the designs are generated by customised generative pre‐trained transformers (GPTs ...

Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKA

open access: yesThe Open Journal of Astrophysics
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutrons and protons. Neutron stars, therefore, provide a unique laboratory for

Noisy Timing Behavior is a Feature of Central Compact Object Pulsars

open access: yesThe Astrophysical Journal
We present a timing study of the three known central compact object (CCO) pulsars, isolated cooling neutron stars in supernova remnants, using observations from Chandra, XMM-Newton, and NICER spanning two decades.

A Giant Glitch in the Energetic 69 ms X-ray Pulsar AXS J161730-505505

open access: yes, 2000
We present new results on the recently discovered 69 ms X-ray pulsar AXS J161730-505505, the sixth youngest sample of all known pulsars. We have undertaken a comprehensive X-ray observing campaign of AXS J161730-505505 with the ASCA, SAX, and XTE observatories and follow its long term spin-down history between 1989 and 1999, using these, archival GINGA
