Tantalum‐Driven Interfacial Reconstruction Enables Ultra‐Low Contact Resistance in TiAlTa/Au GaN HEMTs

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The transformative potential of gallium nitride high electron mobility transistors (GaN HEMTs) in advancing carbon‐neutral power systems remains bottlenecked by contact resistance (Rc) at the metal–semiconductor (M‐S) interface, a critical determinant of switching losses and frequency response.

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Identifying priority areas for conservation to promote connectivity and mitigate the impacts of anthropogenic disturbance

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract As nations seek to expand protected area (PA) networks to cover 30% of land and seas by 2030 (30×30), there is an urgent need for systematic conservation planning and spatial prioritization that considers the broad range of ecological and socioeconomic factors influencing the persistence of biodiversity.

Networking strategies for coordinating interdependent policy issues: A motif approach

Policy Studies Journal, Volume 53, Issue 4, Page 925-943, November 2025.
Abstract Complex societal challenges, such as climate change and environmental degradation, are encumbered by numerous interdependences across different policy issues. Coordination of interdependent policy issues is thus critical. However, coordination challenges persist, partly because coordinating interdependent policy issues among actors often ...

Policy Effectiveness in Managing Drug Shortages: Evidence From South Korea (2015–2024)

World Medical &Health Policy, Volume 17, Issue 3, Page 561-572, September 2025.
ABSTRACT Drug shortages represent a growing policy challenge for healthcare systems worldwide. This study investigates actual drug shortage events in South Korea from 2015 to 2024, using a “Shortage Occurred vs. Shortage Non‐Occurred” framework to distinguish real‐world disruptions from administrative classifications.
