A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Channel Evolution During Drawdown of Iron Gate and Copco I Reservoirs, Klamath River, CA

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract This study used the world's largest dam removal on the Klamath River to investigate channel evolution in unconsolidated silt and clay sediment during reservoir drawdown. Timelapse imagery revealed retrogressing rotational slides and flowslides as key sources of sediment to the re‐emerging channels.

A Call to Industry: Unearthing Synergies in Subsurface Storage Technologies

open access: yesGreenhouse Gases: Science and Technology, Volume 16, Issue 2, Page 187-195, April 2026.
ABSTRACT Subsurface storage technologies (SSTs), including geological CO2 sequestration, underground hydrogen storage, compressed‑air energy storage and thermal energy storage, are emerging as a scalable route for industry to achieve the terawatt‑hour storage flexibility and permanent carbon removal that evolving energy systems demand.

Contrasting patterns of population structure in two habitat‐forming kelp species in southeastern Australia

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 412-426, April 2026.
Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.

Simulations of Photovoltaic Systems on Different Types of Ships in Sweden: Solar Energy Generation, Comparison to Energy Consumption, and Reduction of CO2 Emission

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1273-1285, March 2026.
Investigation of the potential of using solar cells on different types of ships, to see how it reduces energy consumption and emissions of carbon dioxide (CO2). From the reduction in fuel consumption, the fuel cost reduction was estimated, and an approximate payback time for the solar cell system was calculated.
