Analysis of a topping-cycle, aircraft, gas-turbine-engine system which uses cryogenic fuel [PDF]
A topping-cycle aircraft engine system which uses a cryogenic fuel was investigated. This system consists of a main turboshaft engine that is mechanically coupled (by cross-shafting) to a topping loop, which augments the shaft power output of the system.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area
Batteries &Supercaps, Volume 8, Issue 3, March 2025.Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.
