Thermal Analysis of Phase Change Material Based Energy Storage Module With Triply Periodic Minimal Surfaces

Energy Storage, Volume 8, Issue 4, June 2026.
ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...
