Microstructural impact on the optical properties of ZnO nanostructures for dye-sensitized solar cells

Propagating Surface Plasmon Polaritons: Towards Applications for Remote-Excitation Surface Catalytic Reactions

Plasmonics is a well-established fi eld, exploiting the interaction of light and metals at the nanoscale; with the help of surface plasmon polaritons, remote-excitation can also be observed by using silver...

Magnetic domain wall gratings for magnetization reversal tuning and confined dynamic mode localization

High density magnetic domain wall gratings are imprinted in ferromagnetic-antiferromagnetic thinfilms by local ion irradiation by which alternating head-to-tail-to-head-to-tail and head-to-headto-tail-to-tail...

Acetone evaporation and water vapor detection using a caterpillar-like microstructured fiber

A new microstructured optical fiber is presented as a sensor of acetone evaporation. Sensing is performed by observing the time response of the reflected signal at 1550 nm when the device is dipped in...

Standardizing the resolution claims for coherent microscopy

The definition and reporting of spatial resolution for coherent imaging methods varies widely in the imaging community. We advocate the use of a standard spoke-pattern imaging target and the mandatory...

Regenerated Bragg gratings in Panda fibres for simultaneous temperature and force measurements at high temperatures

Simultaneous temperature and force measurements in an extended temperature range up to 500°C were shown with a regenerated fibre Bragg grating in a polarisation maintaining fibre of type Panda. Type I...

Spectroscopy of a superconducting flux qubit in a quasidispersive mode

The properties of a superconducting flux quantum bit (qubit) in the quasidispersive mode, where the frequency of a probe signal is lower than the qubit excitation frequency but is close to it, have been...

A microwave cryogenic low-noise amplifier based on sige heterostructures

A low-noise cryogenic amplifier for the measurement of weak microwave signals at sub-Kelvin temperatures is constructed. The amplifier has five stages based on SiGe bipolar heterostructure transistors...

Josephson systems based on ballistic point contacts between single-band and multi-band superconductors

The Josephson effect in ballistic point contacts between single-band and multi-band superconductors was investigated. It was found that in the case of Josephson junctions formed by a single-band and an...

A shifted-excitation Raman difference spectroscopy (SERDS) evaluation strategy for the efficient isolation of Raman spectra from extreme fluorescence interference

A biochemical characterization of pathologies in biological tissue can be provided by Raman spectroscopy. Often, the raw spectrumis severely affected by fluorescence interference. We report and compare...
