This narrative review focuses on RF exposure in military contexts, emphasizing thermal effects as the established mechanism of harm and discussing safety limits set by bodies such as ICNIRP and IEEE. It reports that whole-body SAR limits (≤4 W/kg) generally prevent dangerous core temperature rises, but localized…

This engineering study describes and simulates a helmet radio-frequency phased array applicator for Thermal Magnetic Resonance (ThermalMR), which combines MRI with targeted RF heating. Using EMF and temperature simulations in a phantom and human head model (including a modeled glioblastoma tumor volume), the authors…

This laboratory/engineering study examined how sulfide modification of nanoscale zero-valent iron interacts with an electromagnetic field to degrade decabromodiphenyl ether. The combined sulfidation+EMF condition reportedly increased the specific reaction rate constant by 7–10× versus nZVI alone. The abstract…

This laboratory/engineering study evaluated thermally enhanced desorption of m-xylene from soil using heat generated by zero-valent iron (ZVI) under low-frequency electromagnetic fields. The abstract reports rapid heating (to ~60°C in 20 minutes) and substantially lower residual m-xylene after 60 minutes versus soil…

This engineering/simulation study evaluates RF applicator array designs for Thermal Magnetic Resonance (ThermalMR), which combines MRI with RF hyperthermia for brain tumor theranostics. Using EMF and temperature simulations at 7.0 T, 9.4 T, and 10.5 T, hybrid loop+SGBT dipole arrays are reported to provide superior…

This laboratory remediation study evaluates low-frequency AC electromagnetic field (AC EMF) induction heating of sulfidated microscale zero-valent iron (S-mZVI) to enhance dechlorination of trichloroethene (TCE). The authors report substantially higher heating of S-mZVI under AC EMF and faster TCE degradation than…

This materials proof-of-concept study explored using radiofrequency EMF to heat magnetic nanoparticles dispersed in PLLA to modulate polymer properties. Heating was monitored by infrared camera, and polymer changes were assessed by differential scanning calorimetry and nanoindentation. The authors report that EMF…

This paper presents an in vitro, noncontact solenoid-coil device designed to deliver intermediate-frequency induced electromagnetic fields that generate electric fields in cell and tissue cultures. The system aims to improve field characterization and reduce conductive heating compared with electrode-based approaches…

This engineering/simulation study evaluates RF applicator concepts for ThermalMR brain tumor heating at 297 MHz (7.0 Tesla) using clinically realistic GBM-based models. EMF simulations compared 10 applicator designs and two SAR-based planning algorithms for small and large target volumes. Power-focused optimization…

This engineering study designed and tested a compact wideband self-grounded bow-tie RF antenna module for a whole-body 7.0 T MRI system, aiming to enable 1H/19F MRI, MR thermometry, and broadband RF thermal intervention. The authors report validated B1 efficiency measurements and phantom-based heating experiments…

This engineering/materials study tested how microwave heating power affects properties of ZnO nanoparticles produced by microwave solvothermal synthesis. Aggregate size reportedly varied (60–120 nm) with microwave power, while individual nanoparticle size and morphology remained constant (average 27 ± 3 nm) under the…

This laboratory study assessed how pH, temperature, and pulsed electric fields (PEF) affect turbidity and protein aggregation in ovomucin-depleted egg white solutions. Heating to 60°C for 10 minutes produced marked aggregation at several pH levels, while PEF caused some aggregation only at pH 5 and 7 under the…
