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 ...

Influence of Laser Powder‐Based Directed Energy Deposition and Heat Treatment on the Thermal Conductivity of Cold‐Work Tool Steel X65MoCrWV3‐2

steel research international, Volume 97, Issue 5, Page 2796-2804, May 2026.
The studied X65MoCrWV3‐2 press hardening tool steel, produced via laser‐based direct energy deposition DED‐LB/M, exhibits a 15‐20% lower thermal conductivity than its conventionally produced equivalent when heat‐treated to operational hardness. The microstructural evolution during the employed direct tempering leads to anisotropic thermal transport, as

Glass bead games: enumeration of possible polytypes based on two stacking vectors and applications to the iron‐ore sinter phases SFCA and SFCA‐I

Acta Crystallographica Section A, Volume 82, Issue 3, Page 145-162, May 2026.
General formulas are presented that allow for the enumeration of polytypes based on translationally equivalent layers and two equivalent arrangements of adjacent layers involving distinct possible stacking vectors, t1 and t2. The results have been applied to the polytypism among two different polysomes of the family of so‐called silico‐ferrites of ...
