JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

Astronomische Nachrichten, EarlyView.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

Cathode Processing Optimization Toward Solid‐State Batteries with Monolithic Oxysulfide Glassy Solid Electrolytes

Batteries &Supercaps, EarlyView.
Mixing order and mixing time affect the ionic and electronic transport properties through a composite cathode made from lithium iron pyrophosphate, an oxysulfide glassy solid electrolyte, and conductive carbon. It is proposed that optimized milling conditions help create robust conduction networks in the composite. Seeking to further the development of

Sodium Mesoxalate as Sacrificial Salt for Biomass‐Derived Hard Carbon // Polyanionic Cathode Na‐Ion Full Cells

Batteries &Supercaps, EarlyView.
This study investigates whether using sodium mesoxalate as a sacrificial additive in two different cathode materials, Na3V2(PO4)3@C and Na3V2O2(PO4)2F@C, can compensate for the initial capacity loss experienced by biomass‐derived hard carbon anodes in full‐cell batteries.

Quantifying Sodium Dendrite Formation in Na5SmSi4O12 Solid Electrolytes

Batteries &Supercaps, EarlyView.
Dendrite formation during cell charging continues to be a key challenge for solid‐state batteries. This study provides insights into dendrite formation in ceramic Na5SmSi4O12 sodium solid electrolytes, discusses the thermodynamical understanding behind the sodium dendrite growth mechanism, and introduces methods to test and statistically quantify ...
