Scalable Room‐Temperature Terahertz Graphene Cameras
Small Methods, EarlyView.ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Reforming Export Control Regimes: Addressing Emerging Technologies Through Responsible Innovation
Global Policy, EarlyView.ABSTRACT The proliferation of dual‐use emerging technologies—such as artificial intelligence (AI), quantum computing, and additive manufacturing—poses a growing challenge for multilateral export control regimes. Designed for tangible goods and slower innovation cycles, existing arrangements increasingly struggle to govern technologies that are ...

Asia Pacific Viewpoint, EarlyView.ABSTRACT Contemporary rural change in Southeast Asia is shaped by complex, intersecting forces that defy simplistic narratives. Researchers must therefore develop new ways to grasp nuanced, non‐linear, and locally specific processes to understand how transformational shifts may occur (or not) in the region.
