Smart current collector—fibre optic hit detection system for improved security on railway tracks

In a deregulated EU railway market, monitoring the vehicle and infrastructure interfaces is mandatory for the enhanced availability of operation and for reducing costs. Therefore, infrastructure managers...

Competition in structural analysis-old wine in new skins

Applying contact to individual silicon nanowires using a dielectrophoresis (DEP)-based technique

One major challenge for the technological use of nanostructures is the control of their electrical and optoelectronic properties. For that purpose, extensive research into the electrical characterization...

Effect of methylation on wavenumber shift of ring breathing mode of pyrimidine in the solution of H2O and D2O by employing Raman difference spectroscopic technique and DFT approach

The relative structural and dynamic properties of hydrogen-bonding between Pyrimidine (Pmd) + H2O and Pmd + D2O, and 4-Methylpyrimidine (Mpmd) + H2O and Mpmd + D2O are investigated experimentally by linear...

High-Visibility Photonic Crystal Fiber Interferometer as Multifunctional Sensor

A photonic crystal fiber (PCF) interferometer that exhibits record fringe contrast (~40 dB) is demonstrated along with its sensing applications. The device operates in reflection mode and consists of a...

A miniaturised autonomous sensor based on nanowire materials platform: the SiNAPS mote

A micro-power energy harvesting system based on core(crystalline Si)-shell(amorphous Si) nanowire solar cells together with a nanowire-modified CMOS sensing platform have been developed to be used in a...
