This study evaluated pulsed electric fields (PEF) as a pasteurization method for raw skim and whole milk across multiple treatment intensities and storage conditions. The abstract reports only minor changes in physicochemical properties and small decreases in some composition measures under stronger treatments.…

This paper describes an engineering method for nucleating nanocrystalline carbon films on monocrystalline silicon using a combination of microwave and radio frequency plasma-assisted chemical vapor deposition. The approach is demonstrated via deposition of nanocrystalline diamond after a seeding step and growth of…

This retrospective cross-sectional study evaluated pulsed radiofrequency (PRF) for chronic pain in patients who did not respond to conventional treatment. Across 24 patients treated at different anatomical regions, 66.7% reportedly achieved at least a 50% reduction in VAS pain scores over a mean follow-up of 8.5…

This paper describes a new magnetization transfer 31P MRS approach (MT-ISIS) for measuring the creatine kinase forward reaction rate in the human brain using a volume 31P/1H RF coil on a clinical 3-T MRI system. The method aims to reduce acquisition time (30 min), avoid scalp muscle contamination, improve RF…

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 engineering study describes a microwave-assisted method to synthesize polyaniline (PANI) nanofibers. Reported yields under microwave irradiation were similar to conventional synthesis but achieved in minutes rather than hours. Structural and morphological characterization (FTIR, Raman, SEM, TEM) reportedly…

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 engineering/food science study examined ohmic heating of peaches at 60 V/cm using bipolar pulses across frequencies from 50 Hz to 1 MHz. Heating time to a target temperature and multiple electrical properties were frequency-dependent, particularly for intact tissue. The authors report faster electro-thermal…

This experimental study examined how pulsed electric fields affect onion tissue integrity and texture across different field strengths and pulse counts. It reports distinct critical field strengths for plasma membrane versus tonoplast membrane breakdown, with higher thresholds needed for tonoplast disruption. Effects…

This study evaluated high-intensity pulsed electric fields (HIPEF) as a processing method to inactivate polyphenoloxidase (PPO) in strawberry juice. Using response surface methodology at a constant electric field of 35 kV/cm, the authors report strong PPO reductions across tested parameter ranges. Bipolar mode,…

This paper is a review of two-dimensional electron dynamics in microscopically inhomogeneous magnetic fields, focusing on magnetic potentials varying on scales smaller than the mean free path. It covers early work on localization in random magnetic fields, methods to fabricate magnetic potentials, and drift-diffusion…

This study characterizes the electrical potential on the surface of ~300 nm SiO2 grown on single-crystalline Si under ambient conditions using electric field microscopy. It reports an inhomogeneous surface potential with fluctuations up to ~0.4 V over ~1 µm regions. The authors propose these fluctuations could affect…

This in vitro study tested electromagnetic compatibility between passive RFID readers and 15 pacemakers plus 15 ICDs across 134 kHz, 13.56 MHz, and 915 MHz bands. EMI reactions were common with low-frequency RFID and rare with high-frequency RFID, while no reactions were observed with ultra-high-frequency or…

This SCENIHR Opinion updates earlier 2009 SCENIHR documents on EMF health effects and research needs, focusing on new information and remaining knowledge gaps. The abstract primarily characterizes sources and patterns of exposure across static, ELF, IF, and RF fields in both public and occupational settings. It notes…

This cross-sectional questionnaire study of 196 parent–adolescent dyads examined how cell phone calling patterns relate to perceptions of truthfulness, parental knowledge, and family relationships. More frequent parental calling was associated with lower perceived truthfulness, and calls made when upset were linked…

This monocentric study evaluated outpatient feasibility and outcomes of radiofrequency transurethral needle ablation (TUNA) for benign prostatic hyperplasia in patients who did not respond to medical therapy. In the outpatient subgroup, urinary symptom scores, quality of life, flow measures, and residual urine…

This paper describes a procedural technique for transseptal puncture that uses brief pulses of radiofrequency energy delivered from a standard electrosurgical cautery generator through the needle tip. The approach is presented as a way to facilitate septal traversal when tissue is elastic, aneurysmal, or thickened,…

This engineering-focused study examines failure of needle-shaped specimens exposed to very high electric fields in field-ion microscopy. The authors report experiments indicating breakdown may be initiated by nanoparticles detached from a point anode. They propose a mechanism in which expanding cathode plasma…

This study compared slow conventional air defrosting with fast radio frequency (RF) defrosting/tempering in lean beef (whole, minced, and comminuted) using drip loss, NMR relaxometry, and dielectric spectroscopy. RF thawing was associated with lower drip loss and lower micronutrient loss in drip than air thawing,…

This theoretical paper analyzes vortex solutions in two-component superconductors within a U(1) x U(1) Ginzburg-Landau framework. It reports that exponentially screened magnetic fields are only found in special cases, while most parameter choices yield delocalized magnetic fields with slowly decaying tails. It also…

This Physical Review Letters paper reports magnetotransport measurements on a gated LaAlO3/SrTiO3 interface to assess the main effect of an applied gate electric field. The authors find that mobility changes dominate over sheet carrier density changes (mobility variation reported as nearly fivefold larger). They also…
