A multi-purpose imaging endstation for high-resolution micrometer-scaled sub-second tomography

Time-resolved imaging of dynamic processes, ranging from biological in vivo studies to materials under in situ and in operando conditions, requires a flexible endstation capable of controlling complex components that interact in different configurations an ...

Prediction of transformation products during ozonation of micropollutant-containing waters

Minju Lee

Ozonation, which is widely used for drinking water disinfection, has recently been applied to mitigate potentially harmful effects of micropollutants (e.g., pharmaceuticals, personal care products, pesticides, etc.) present in municipal wastewater effluent ...

Improving Osteoblast Response In Vitro by a Nanostructured Thin Film with Titanium Carbide and Titanium Oxides Clustered around Graphitic Carbon

Giovanni Longo

Introduction Recently, we introduced a new deposition method, based on Ion Plating Plasma Assisted technology, to coat titanium implants with a thin but hard nanostructured layer composed of titanium carbide and titanium oxides, clustered around graphitic ...

Impulse waves generated by snow avalanches: Momentum and energy transfer to a water body

Christophe Ancey

When a snow avalanche enters a body of water, it creates an impulse wave whose effects may be catastrophic. Assessing the risk posed by such events requires estimates of the wave’s features. Empirical equations have been developed for this purpose in the c ...

Evaluation of silicon tuning-fork resonators under space-relevant radiation conditions

Herbert Shea, Alex Dommann, Tobias Bandi

This work reports on irradiations made on silicon bulk-acoustic wave resonators. The resonators were based on a tuning fork geometry and actuated by a piezoelectric aluminum nitride layer. They had a resonance frequency of 150 kHz and a quality factor of a ...

Optical microscopy for imaging through scattering media

Xin Yang

Optical microscopy has been widely used in the life sciences and biological research for several decades. It possesses many advantages over x-ray radiography, computed tomography, ultrasound imaging and magnetic resonance imaging, in terms of being low cos ...

Measured and Modeled Toxicokinetics in Cultured Fish Cells and Application to In Vitro - In Vivo Toxicity Extrapolation

Kristin Schirmer, Julita Maria Stadnicka-Michalak

Effect concentrations in the toxicity assessment of chemicals with fish and fish cells are generally based on external exposure concentrations. External concentrations as dose metrics, may, however, hamper interpretation and extrapolation of toxicological ...

Bioavailability of inorganic nanoparticles to planktonic bacteria and aquatic microalgae in freshwater

Paul Bowen, Nadia Rachel Von Moos

Over the past few years, engineered nanomaterials (ENMs) have penetrated nearly every sector of modern life and their broad-scale use is steadily and rapidly increasing. The (expected) elevated levels of ENMs in the environment raise concerns with regard t ...

Proton-Radiation Tolerance of Silicon and SU-8 as Structural Materials for High-Reliability MEMS

Herbert Shea, Antonia Neels, Alex Dommann, Tobias Bandi

The susceptibility of single-crystal silicon and SU-8 resonators to proton-radiation induced degradation was investigated. Both materials are in widespread use for microsystems structures, thus the stability of the mechanical properties must be ensured ove ...

Numerical modelling of optical trapping in hollow photonic crystal cavities

Romuald Houdré, Ulagalandha Perumal Dharanipathy

Photonic crystal (PhC) devices owing to their strong confinement of electromagnetic energy are considered to be excellent candidates for on chip optical trapping of dielectric or biological particles in the nanometer range. In this work, we study and prese ...
