Modeling of Human Body-coupled Electric Field Interference in Unshielded Ultra-Low Field MRI
Jiali He, Yamei Dai, Sheng Shen +2
Portable ultra-low field MRI (ULF-MRI) systems operated in unshielded environments are susceptible to electromagnetic interference (EMI). Subject presence in the imaging region wil…
Active noise cancellation in ultra-low field MRI: distinct strategies for different channels
Jiali He, Sheng Shen, Jiamin Wu +4
Ultra-low field magnetic resonance imaging(ULF-MRI) systems operating in open environments are highly susceptible to composite electromagnetic interference(EMI). Different imaging…
Hybrid antiferroelectric-ferroelectric domain walls in noncollinear antipolar oxides
Ivan N. Ushakov, Mats Topstad, Muhammad Z. Khalid +15
Antiferroelectrics are emerging as advanced functional materials and are fertile ground for unusual electric effects. For example, they enhance the recoverable energy density in en…
Local doping of an oxide semiconductor by voltage-driven splitting of anti-Frenkel defects
Jiali He, Ursula Ludacka, Kasper A. Hunnestad +12
Layered oxides exhibit high ionic mobility and chemical flexibility, attracting interest as cathode materials for lithium-ion batteries and the pairing of hydrogen production and c…
Ferroelectric domain walls for environmental sensors
L. Richarz, I. C. Skogvoll, E. Y. Tokle +9
Domain walls in ferroelectric oxides provide fertile ground for the development of next-generation nanotechnology. Examples include domain-wall-based memory, memristors, and diodes…
