Membrane fouling from ammonia recovery analyzed by ATR-FTIR imaging

The composition of membrane fouling from membrane distillation ammonia from model pig manure and the change in fouling composition as a result of three cleaning approaches was examined using ATR-FTIR imaging...

Trends and future of Fiber Bragg Grating sensing technologies: tailored Draw Tower Gratings (DTG(r)s)

Today fiber Bragg gratings are commonly used in sensing technology as well as in telecommunications. Numerous requirements must be satisfied for their application as a sensor such as the number of sensors...

Resolving a misconception about structured illumination

Applying structured illumination microscopy to coherent imaging modalities such as scattering does not yield any additional information beyond that provided by oblique illumination. It thus yields no resolution...

Synthesis and Bioconjugation of Plasmonic Nanoparticles for Bioanalytical Sensing

Localized Surface Plasmon Resonance (LSPR) biosensing using gold nanotriangles: Detection of DNA hybridization events at room-temperature

We present a proof-of-concept of the application of gold nanotriangles in sequence specific DNA detection, using localized surface plasmon resonance (LSPR) spectroscopy and dark field optical microscopy....

Comparative two- and three-dimensional analysis of nanoparticle localization in different cell types by Raman spectroscopic imaging

The increasing production and application of engineered nanomaterials requires a detailed understanding of the potential toxicity of nanoparticles and their uptake in living cells and tissue. For that...

Transient absorption in pumped Yb fibers opens a path to photodarkening

We investigated the strong absorption change appearing in ytterbium (Yb)-doped silica simultaneously with Yb3+ excitation and vanishing immediately after pump power switch-off. The transient absorption...

Calibration of SQUID vector magnetometers in full tensor gradiometry systems

Measurement of magnetic vector or tensor quantities, namely of field or field gradient, delivers more details of the underlying geologic setting in geomagnetic prospection than a scalar measurement of...

Reconstructing the 3D shapes of droplets in glass microchannels with application to Bretherton’s problem

The outstanding potential of absorbance imaging for the 3D shape analysis of dynamic scenes in multiphase flows is demonstrated and experimentally confirmed. The experimental procedures and workflows have...

Hydrodynamic Models of a Microchannel System with Integrated Nanofilter Membranes for Capturing Blood Cells at the Pore Array of the Membrane
