This in vitro study examined how an externally applied electric field influences the self-assembly of oppositely charged molecules in water into an ordered membrane. The authors report that electric fields changed the kinetics of membrane formation and altered membrane thickness, nanofiber growth orientation, and…

This study reports an aqueous two-phase extraction method for equine spleen ferritin using polyethylene glycol (PEG) and hydroxyethyl starch (HES). Ferritin partitioning depended on PEG/HES concentrations and PEG molecular weight, and applying a magnetic field increased ferritin accumulation in the PEG-rich phase…

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 experimental and modeling study examined pulsed electric field (PEF) permeabilization in several fruit and vegetable tissues at 293 K using 1000 μs pulses and field strengths of 400 and 1000 V·cm(-1). While electroporation theory predicts greater damage in tissues with larger cells, the authors report this…

This engineering-focused mouse fMRI study evaluated a 400-MHz cryogenic RF probe (CryoProbe) versus a conventional room-temperature surface coil during electrical forepaw stimulation. The CryoProbe increased image SNR and temporal SNR and reduced temporal noise compared with the room-temperature coil. The authors…

This paper presents a theoretical model of giant phospholipid vesicle deformation in an alternating-current electric field, based on minimizing membrane bending energy and electric-field energy. The model treats the membrane and surrounding aqueous media as leaky dielectrics and reports good quantitative agreement…

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 condensed-matter study investigates highly oriented pyrolytic graphite under very strong magnetic fields at low temperature. It reports a magnetic-field-induced charge density wave transition and a subsequent sign reversal of the Hall coefficient from negative to positive. The reported angular dependence…

This paper presents a mesoscopic transport modeling framework (NEGF plus a real-space π-orbital model) to study how a uniform perpendicular magnetic field affects electronic transport in armchair graphene nanoribbons. The authors report width-dependent equilibrium current profiles and edge-localized transport under…

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 neutron diffraction study quantifies how tetragonal structural domains in SrTiO3 redistribute below 105 K under external electric fields and uniaxial mechanical stress. The authors report that electric field and stress act competitively, and that applying both produces complex domain redistribution. The results…

This laboratory study investigates how magnetic field and pressure affect valence and magnetic transitions in the compound EuPtP. High-field analysis suggests a mixed valence state at low temperature and discontinuous changes in Eu2+ fraction at two transition temperatures. Pressure increases the transition…

This paper analyzes anomalous magnetic-field and temperature dependences observed in MgB(2) superconductivity experiments using a two-order-parameter Ginzburg-Landau theory with two length scales. The authors numerically solve the nonlinear Ginzburg-Landau equations for arbitrary applied fields between Hc1 and Hc2 to…

This theoretical/physics paper examines how an in-plane uniform electric field affects the de Haas-van Alphen (dHvA) effect in graphene. It reports that magnetization, magnetic susceptibility, and dHvA oscillation behavior depend on a dimensionless parameter β = E/(vF B), with divergences described at a critical…

This experimental study examined nucleation of superconductivity at the surface of a single-crystal yttrium hexaboride (YB6) in a tilted dc magnetic field. The authors measured Hc3 on each side of the sample as a function of the angle between the field and the surface. They report Hc3/Hc2 ≈ 1.28 for a perpendicular…

This laboratory/engineering study examined electric-field-induced structuring in clay-oil suspensions using WAXS, SEM, rheometry, and electrical measurements. Particle orientation was quantified via an orientational order parameter derived from diffraction peak azimuthal changes, and chain versus column formation was…

This laboratory study examined how temperature and prior electric-field exposure affect low-field conductivity in the charge density wave material o-TaS3. Conductivity differed between cooling and heating below the CDW transition, and applying increasing electric fields drove the system toward a stable,…

This paper studies the spin-glass transition in a magnetic field using a diluted one-dimensional long-range Ising model with distance-dependent bond probability. The authors report evidence for a spin-glass transition in a magnetic field both within and beyond the mean-field regime. They also report such evidence for…
