Metal-Organic Frameworks as Adsorbents for Hydrogen Purification and Precombustion Carbon Dioxide Capture

Selected metal-organic frameworks exhibiting representative properties-high surface area, structural flexibility, or the presence of open metal cation sites-were tested for utility in the separation of CO2 from H 2 via pressure swing adsorption. Single-com ...

Self-entrainment of air on stepped spillways

Michael Pfister

The pseudo-bottom-inception point related to air entrainment is located further upstream on stepped spillways than on smooth spillways, for otherwise identical conditions. Its position is relevant concerning cavitation aspects, flow losses and flow depths. ...

Improving the accuracy of four-receiver acoustic Doppler velocimeter (ADV) measurements in turbulent boundary layer flows

Ulrich Lemmin, Fereshteh Bagherimiyab Hunkeler

Acoustic Doppler instrument measurements suffer from random spikes and Doppler noise. Using a four-receiver ADV (acoustic Doppler velocimeter; Vectrino manufactured by Nortek) that allows recording beam velocities, we combine a spike-removal procedure on t ...

Distributed Communication in Swarms of Autonomous Underwater Vehicles

Felix Stephan Schill

Effective communication mechanisms are a key requirement for schools of submersible robots and their meaningful deployment. Large schools of identical submersibles require a fully distributed communication system which scales well and optimises for ”many-t ...

A virtual valve for smooth contamination-free flow switching

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Nicolas Demierre, Anja Kunze, Raphaël Tornay, Joël Theytaz, Mario Schlund, Grazia Loche

We present a channel geometry that allows for clean switching between different inlets of a microchip without any contamination of the inlets or the downstream flow. We drive this virtual valve with a pneumatic pressure setup that minimizes disturbance of ...

Hybrid Ultrasonic Motor and Electrorheological Clutch System for MR-Compatible Haptic Rendering

Hannes Bleuler, Dominique Chapuis, Roger Gassert, Etienne Burdet

Using haptic interfaces in combination with functional magnetic resonance imaging (fMRI) could lead to important insights into the brain mechanisms of human motor control and related dysfunctions. However, in addition to the usual requirements for haptic i ...

Scattering experiments with a diving cylinder

Olivier Martin

We present numerical experiments of light scattering by a circular dielectric cylinder embedded in a stratified background, using the Greens tensor technique. The stratified background consists of two or three dielectric layers, the latter forming an anti- ...

Passive micro-flow regulator for drug delivery system

Philippe Renaud

In this paper an innovative micromachined passive flow regulator for implantable drug delivery systems is presented. The aim is to passively achieve a constant flow rate over a certain pressure range through linear variation of a flow resistance. This flow ...

Prediction of Two-Phase Flow Patterns for Evaporation of Refrigerant R–407C Inside Horizontal Tubes.

John Richard Thome, Daniel Favrat, Olivier Zürcher

Two-phase flow pattern data have been obtained experimentally for R-407C flowing inside 12 mm bore sight glasses, which were located at the outlets of 3 m long, plain bore copper tube heat transfer test sections. The tests covered nominal mass velocities o ...
