Laser Powder Bed Fusion of Copper–Tungsten Composites for Heat Sink Applications in High‐Power Electronics

Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was

Modeling and Design Principles for Plasmonic Nanoparticle‐Enhanced Perovskite Solar Cells: A Comprehensive Review

Solar RRL, Volume 10, Issue 7, 15 April 2026.
Perovskite solar cells have reached high power‐conversion efficiencies, yet further gains require improved optical design, particularly in the near‐infrared. This review surveys analytical and numerical studies on plasmonic nanoparticle‐enhanced perovskite solar cells (PSCs), clarifying key enhancement mechanisms. The influence of nanoparticle material,
