40-Gbit/s single-wavelength alternate polarization soliton field experiment was performed on a dispersion-shifted fiber installed cable 500 km long. Comparison with an equivalent fiber installed in laboratory showed that the main impairment was due to the polarization-mode dispersion.
Herein, we report a novel approach for the design of a colorimetric aptasensor based on functionalized gold nanoparticle probes. This approach relies on the conjugation of nanoparticles by two functional DNA and RNA hairpins that engage specific kissing (loop-loop) interactions in response to the addition of a small analyte ligand, leading to particle(More)
Interfacial contact of two-dimensional graphene with three-dimensional metal electrodes is crucial to engineering high-performance graphene-based nanodevices with superior performance. Here, we report on the development of a rapid "nanowelding" method for enhancing properties of interface to graphene buried under metal electrodes using a focused electron(More)
We report on the first demonstration of controllable carbon doping of graphene to engineer local electronic properties of a graphene conduction channel using focused electron beam induced deposition (FEBID). Electrical measurements indicate that an "n-p-n" junction on graphene conduction channel is formed by partial carbon deposition near the source and(More)
