Portable impedance-sensing device for microorganism characterization in the field

A variety of biosensors have been proposed to quickly detect and measure the properties of individual microorganisms among heterogeneous populations, but challenges related to cost, portability, stability, sensitivity, and power consumption limit their app ...

An in-situ synchrotron study on microplastic flow of electrodeposited nanocrystalline nickel

Steven Van Petegem, Helena Van Swygenhoven

Deformation in nanocrystalline (NC) materials is strongly influenced by the presence of a large fraction of grain boundaries. We present a comparative study on the role of intragranular root-mean-square strain and crystal-lographic texture on recovery proc ...

Visible spectrum extended-focus optical coherence microscopy for label-free sub-cellular tomography

Theo Lasser, Daniel Pawel Szlag, Arno Pino Bouwens, Jérôme Extermann, Adrien Charles-François Raymond Descloux, Paul James Marchand, Miguel Sison, David Nguyen, Séverine Coquoz

We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 μm axial and 0.4 μm lateral resolution maintained over a depth of 40 μm, while preserving the advantages of Fourier domain OCM. Our system uses an ultra-broad spectrum from ...

Plastic pollution in Swiss surface waters: nature and concentrations, interaction with pollutants

Luiz Felippe De Alencastro, Florian Faure, Colin Demars

Marine microplastic (,5 mm) water pollution has met growing public and scientific interest in the last few years. The situation in freshwater environments remains largely unknown, although it appears that they play an important role as part of the origin o ...

Microstructure and deformation mechanisms in nanocrystalline Ni-Fe. Part II. In situ testing during X-ray diffraction

Helena Van Swygenhoven, Steven Van Petegem

Deformation mechanisms in nanocrystalline electrodeposited Ni (26 nm) and Ni-Fe (12 nm) are studied by strain rate sensitivity experiments and in situ mechanical testing during X-ray diffraction. We find a relatively low strength for Ni-Fe, which may be as ...

Tailoring the hydraulic impedance of out-of-plane micromachined electrospray sources with integrated electrodes

Herbert Shea

Hydraulic impedance is a critical parameter for the operation of electrospray emitters, and for preventing flooding when spraying from arrays of emitters. Controlling flow rate by tuning the flow impedance allows accessing different operating modes, such a ...
