Thermal–Hydraulic Performance and Entropy Generation Analysis of a Nanoencapsulated Phase Change Material Suspension Flow Between Fixed and Rotating Cylinders Under Magnetic Field Influence

open access: yesHeat Transfer, EarlyView.
ABSTRACT This study investigates the thermal–hydraulic performance of a nanoencapsulated phase change material (NEPCM) suspension in a rectangular enclosure featuring two counterrotating cylinders positioned between three fixed hot and three fixed cold cylinders under magnetic field influence.

Manipulating Anti‐Site Defects in α‐MgAgSb for Thermoelectric Cooling Enhancement

open access: yesInterdisciplinary Materials, EarlyView.
This study reveals that Mg‐Ag anti‐site defects in α‐MgAgSb create staggered nanoscale zones, effectively scattering phonons while preserving carrier transport. Zn doping optimizes defect formation, achieving a high zT of ~0.45 at 200 K and ~0.75 average (200–400 K).

Raman Study of the Slobodka Ordinary Chondrite

open access: yesJournal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.
