New Arabic Records From Cairo on Supernovae 1181 and 1006

Astronomische Nachrichten, EarlyView.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...

Exploring Rochelle Salt Aqueous Solutions for Supercapacitors: Transport, Stability, and Performance

Batteries &Supercaps, EarlyView.
This study investigates potassium sodium tartrate tetrahydrate (SPTa) as a sustainable and reliable electrolyte for electrochemical double‐layer supercapacitors. SPTa dissolves in water, forming Na+ and K+ ions that enable high ionic conductivity, low viscosity, and stable electrochemical performance with activated carbon electrodes offering a ...
