Noise reduction in optically pumped magnetometer assemblies

Application of an asymmetric helical tube reactor for fast identification of gene transcripts of pathogenic viruses by micro flow-through PCR

We have established a fast PCR-based micro flow-through process consisting of a helical constructed tube reactor. By this approach we can detect transcripts of measles and human papilloma virus (HPV) by...

Quantitative mineral analysis using Raman spectroscopy and chemometric techniques

In Situ Electron Microscopy Mechanical Testing of Silicon Nanowires Using Electrostatically Actuated Tensile Stages

Two types of electrostatically actuated tensile stages for in situ electron microscopy mechanical testing of 1-D nanostructures were designed, microfabricated, and tested. Testing was carried out for mechanical...

Experimental determination of the dispersion relation of light in metamaterials by white-light interferometry

Design and implementation of cryogenic semiconductor amplifiers as interface between RSFQ circuits

Rapid single flux quantum (RSFQ) circuits create high interest in cryogenic amplifiers as interface to commercial room temperature electronics. The requirements for the amplifiers are an extremely high...

Nanobiophotonics: photons that shine their light on the life at the nanoscale

Tunable light source for narrowband laser excitation: application to Raman spectroscopy

In many laser spectroscopic techniques, such as fluorescence Raman and resonance Raman spectroscopy the choice of laser excitation wavelength is of central importance. Thus, it is desirable to have a single...

Gold and gold-silver core-shell nanoparticle constructs with defined size based on DNA hybridization

Nanoparticles represent versatile building blocks in material science and nanotechnology. Thereby, the defined assembly of nanostructures (13 and 56 nm in diameter, respectively) is of significant importance....

Toward in Vivo Chemical Imaging of Epicuticular Waxes

Epicuticular waxes, which are found on the outer surface of plant cuticles, are difficult to study in vivo. To monitor the growth, development, and structural alterations of epicuticular wax layers, coherent...
