This engineering paper describes a fiber-based method for stable radio-frequency dissemination using a hybrid frequency modulation approach. Two RF components are transmitted simultaneously using a single laser diode, with one component used for phase fluctuation detection and the other providing a compensated stable…

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 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 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 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 study describes an electrooptical technique for polydisperse colloid solutions using short pulses of strong sine-shaped electric field, intended for systems that cannot withstand prolonged field exposure. The authors report that key particle parameters can still be extracted from the resulting experimental data.…

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 study measured dielectric properties of beef Semitendinosus across 27, 915, and 1800 MHz and temperatures from -5 to 130 °C using an open-ended coaxial probe. The results indicate that frequency, temperature, and muscle fiber orientation influence dielectric constant, dielectric loss, and calculated penetration…

This engineering-focused paper compares carbon nanotube growth in dense low-temperature plasma versus on a substrate surface using hybrid/Monte-Carlo simulations. It reports that plasma parameters strongly influence ion fluxes and nanotube growth kinetics, with large differences in growth rates and fluxes between…

This engineering study examines multi-wall carbon nanotubes suspended in water exposed to AC electric fields generated by 3D electrodes. It reports field-induced polarization leading to nanotube alignment and long-range, electrically conducting assemblies spanning the electrode gap, with assembly length controlled by…

This paper reports that the electronic gap in bilayer graphene can be controlled externally via a gate bias (electric field effect). Using magnetotransport (Shubnikov-de Haas) data and a tight-binding model, the authors extract the gap as a function of electronic density. They report tuning the gap from zero to…
