Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Microstructure Characteristics and Strength–Ductility Mechanisms of a Novel Neutron Shielding Al‐6Mg‐5Gd Alloy Fabricated by Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Al‐based neutron shielding materials suffer from poor laser powder bed fusion (LPBF) processibility, hindering their simultaneous achievement of good printability and exceptional mechanical properties. In this work, the newly developed rare‐earth Al alloy (i.e., Al‐6Mg‐5Gd) was processed by LPBF technique to meet the printability, mechanical ...

Process–Structure–Property Relationship of Laser Additive Manufactured Thermoelectric Silver Selenide

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
This research establishes process–structure–property connections for n‐type silver selenide fabricated via laser powder bed fusion. By correlating laser processing parameters with melt pool and microstructural features, the study demonstrates the feasibility of additively manufacturing dense thermoelectric structures.
