All-in-One, High-Power Microwave System
A device was developed that uses composite-based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. Read on to learn more.
Q&A: AR/AI
Dr. Aaron J. Wilson and his team at Oak Ridge National Laboratory, Lawrence Livermore National Laboratory, and Pacific Northwest National Laboratory have developed The Grid Event Signature Library — an open-access online collection of datasets containing waveforms that are visual representations of behaviors of the electric grid, which can help analyze anomalous events.

Briefs: Energy
Flow batteries can serve as backup generators for the electric grid. Flow batteries are one of the key pillars of a decarbonization strategy to store energy from renewable energy resources. Their advantage is that they can be built at any scale, from the lab-bench scale, as in this PNNL study, to the size of a city block.
