A Low‐Cost and Compact High‐Frequency Gallium Nitride Gradient Power Amplifier for Low‐Field MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2992-2999, May 2026.
ABSTRACT Purpose To reduce the upfront cost of small, low‐field MRI systems, while expanding the capabilities of their gradient systems. Methods A gradient power amplifier was designed to leverage the lowering cost of Gallium Nitride (GaN) power transistors and high speed logic, to achieve high efficiency and responsiveness for driving gradient coils ...

Pressurized Solid Oxide Electrolysis—Operational Strategies

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT Pressurized high‐temperature electrolysis is a promising pathway for high‐efficiency hydrogen production that enables direct compression and heat recovery opportunities not accessible to low‐temperature electrolysis. While laboratory testing is routinely conducted near atmospheric pressure, there is increasing interest in commercial deployment

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

InfoMat, Volume 8, Issue 4, April 2026.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...
