Hydrogen bonding in different pyrimidine-methanol clusters probed by polarized Raman spectroscopy and DFT calculations

We report on the hydrogen bonding between pyrimidine (Pd) and methanol (M) as H-donor in this study. Hydrogen bonds between pyrimidine andmethanolmolecules as well as those between differentmethanolmolecules...

Optical resonances of self-organized monocrystalline Au nanoparticles embedded in SrTiO3 matrix

We report on a novel fabrication scheme obtaining metal nanoparticles grown in a crystal high index ambient, i.e. SrTiO3 (STO). Starting from a deposited Au layer ellipsoidal and orientated Au nanoantennas...

Spectral optical monitoring of nitrate in inland and seawater with miniaturized optical components

Miniaturized spectral analytical systems become ever increasingly important for in situ monitoring of natural waters’ nutrients, such as nitrate, phosphate or ammonium. A miniaturized UV spectral photometer...

Microstructured Optical Fiber Sensors Embedded in a Laminate Composite for Smart Material Applications

Fiber Bragg gratings written in highly birefringent microstructured optical fiber with a dedicated design are embedded in a composite fiber-reinforced polymer. The Bragg peak wavelength shifts are measured...

Mikrospektroskopie an lebenden Pilzen und Pflanzen

Um Wachstumsvorgänge in Pilzen oder Umwelteinflüsse auf Pflanzen zu untersuchen, eignen sich Verfahren der Ramanspektroskopie und -mikroskopie. Sie machen in lebenden Organismen die Morphochemie sichtbar,...

Protein-Induced Excited-State Dynamics of Protochlorophyllide

The light-drivenNADPH:protochlorophyllide oxidoreductase (POR) is a key enzyme of chlorophyll biosynthesis in angiosperms. POR’s unique requirement for light to become catalytically active makes the...

Biofunctionalization of zinc oxide nanowires for DNA sensory applications

We report on the biofunctionalization of zinc oxide nanowires for the attachment of DNA target molecules on the nanowire surface. With the organosilane GOPS (Glycidyloxypropyltrimethoxysilane) acting as...

Temperature Fiber Laser Sensor Based on a Hybrid Cavity and a Random Mirror

In the present work, a simple temperature fiber laser sensor configuration is proposed. The temperature fiber laser sensor is based in the combination of a Fabry-Perót hybrid cavity and a random mirror....

Optical Refractometer Based on Multimode Interference in a Pure Silica Tube

It is presented a multimode interferometer based-fibre optic sensor with a silica tube section aimed to measure refractive index variations of surrounding liquids. The sensing head is a silica tube section...
