The paper describes the development of RF-shielded hats using a microwave absorbing sheet intended to reduce EMF exposure to a cameraman’s head. Three hat designs are described, and measurements are planned/performed in an anechoic chamber using a wireless video camera operating around 1.9–2.7 GHz, including a 2.45…

This engineering/physical chemistry study quantified interfacial electric fields in dye-sensitized solar cells using a newly described electroabsorption signature. Reported field strengths depended on the electrolyte cation (higher for divalent cations) and were linked to TiO2(e−) + I3− charge recombination kinetics…

This engineering study assesses the risk of failure of composite high-voltage insulators in desert environments where sand accumulation and moisture can create conductive layers and leakage currents. Using realistic Sinai sand grain size and salinity data and an ABB composite insulator as a case study, the authors…

This engineering-focused paper reports the design principle and performance of a MALDI ion source ("MALDI-2") combining rarefied supersonic gas jets with weak electric fields and injection into gas-filled RF multipoles. The abstract reports rapid collisional cooling (

This animal study evaluated a therapeutic 120 Hz pulsed EMF device (10–20 mT) in C3H mice bearing implanted murine mammary adenocarcinoma tumors. Across seven treated groups, EMF exposure over 12 days was reported to suppress tumor growth, with specific dose/time regimens described as most effective. The authors also…

This paper describes a SAR measurement system for a 3G mobile phone (1718.5 MHz) using brain phantom material in a Perspex box sized to a small rat volume, with induced fields measured at multiple locations. SAR was computed from induced-field measurements and also estimated experimentally via temperature rise, with…

This engineering study describes using antenna-coupled microwave radiation to enhance laser-induced breakdown spectroscopy (LIBS) emission from a Gd2O3 sample at reduced pressure. The authors report substantially increased plasma emission intensity, higher-temperature plasma, and longer emission lifetime when…

This study models nematic liquid crystals embedded in random polymer networks, where disorder disrupts long-range order and produces a glassy state. It uses simulations and an Imry-Ma-like analytic approach to visualize domains, predict domain size, and calculate the response to an applied electric field. The authors…

This animal experiment assessed integral and pulsed bioelectric activity across rabbit brain regions during exposure to low-intensity magnetic and electromagnetic fields. The authors report that brain-region participation in CNS reactions varied across exposure parameters and conditions and depended strongly on…

This paper proposes that Pb nanowires created by repeated indentation of a Pb tip on a Pb substrate may exhibit topological superconducting properties in an external magnetic field. The authors analyzed conductance curves from different nanowires and report that, in a few cases, the critical current shows a peculiar…

This physics study uses analytical calculations and Monte Carlo simulations to determine ground-state structures of monodisperse ferrofluid monolayers under external magnetic fields. It reports structural transitions depending on whether the field is perpendicular or parallel to the monolayer plane, with different…

This paper presents a theoretical calculation of the stationary probability density for a harmonic oscillator embedded in an electromagnetic field by solving the Fokker-Planck equation exactly. The magnetic field is treated as constant, while the electric field is modeled as an external stochastic force with…

This engineering/materials study describes a template-free solution-phase method to synthesize well-aligned nickel nanochains under applied magnetic fields. The authors report that nanochain size and morphology can be tuned by reaction temperature and magnetic field conditions, and explain alignment via magnetic…

This engineering paper proposes a control method for a photo-electromagnetic field (EMF)-based ammonia gas sensor that uses a wireless network and adjusts illumination light intensity. It reports that measurement error is minimized over 3800 ppm ammonia when the concentration corresponds to an optimal illumination…

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability. The authors state…

This study investigated how exposure to a static magnetic field affects electricity production in Shewanella-inoculated microbial fuel cells across different reactor configurations. A 100 mT field was reported to increase maximum voltage and the effect was described as immediate and reversible, with possible adverse…

This materials study reports that ZnO nanorod polymer hybrids can form liquid-crystalline phases and exhibit orientation switching under an applied AC electric field. The orientation reportedly changes from planar to homeotropic, analogous to switching in low-molecular liquid crystals. Dielectric measurements and…

This paper presents a theoretical model to investigate the origin of a mixed symmetry pairing state in the high-Tc superconductor YBa2Cu3O7-δ under applied magnetic fields between Hc1 and Hc2. The authors report that the model’s results, and their stated agreement with relevant experimental data, suggest orthorhombic…

This materials-physics study investigated quadrupolar hyperfine interactions of (111)In→(111)Cd probes in polycrystalline Zr4Al3 and Hf4Al3 containing minority (Zr/Hf)3Al2 phases. The authors observed a strong preference of (111)In solutes for the minority (Zr/Hf)3Al2 phases. Ab initio EFG calculations were used to…
