Ultralow Interfacial Tension Measurement through Jetting/Dripping Transition

In this paper, we present a dynamic microfluidic tensiometer able to perform measurements over more than four decades and which is suitable for high throughput experimentations. This tensiometer is able to withstand hard conditions such as high pressure, h ...

Multistep Photoluminescence Decay Reveals Dissociation of Geminate Charge Pairs in Organolead Trihalide Perovskites

Shaik Mohammed Zakeeruddin, Marius Franckevicius

Charge carrier dynamics in organolead iodide perovskites is analyzed by employing time-resolved photoluminescence spectroscopy with several ps time resolution. The measurements performed by varying photoexcitation intensity over five orders of magnitude en ...

Ordering Events Based on Intentionality in Cyber-Physical Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab

We consider cyber-physical systems (CPSs) comprising a central controller that might be replicated for high-reliability, and one or more process agents. The controller receives measurements from process agents, causing it to compute and issue setpoints tha ...

Adaptive control of a deployable tensegrity structure

Ian Smith, Ann Christine Sychterz, Nicolas Willy Veuve

Deployable structures belong to a special class of moveable structures that are capable of form and size change. Controlling movement of deployable structures is important for successful deployment, in-service adaptation and safety. In this paper, measurem ...

Nonadiabatic effects in electronic and nuclear dynamics

Majed Chergui, Ursula Röthlisberger, Jiri Vanicek, Martin Peter Bircher, Tomas Zimmermann, Elisa Liberatore, Aurélien Kevin Fabrice Patoz, Nicholas John Browning

Due to their very nature, ultrafast phenomena are often accompanied by the occurrence of nonadiabatic effects. From a theoretical perspective, the treatment of nonadiabatic processes makes it necessary to go beyond the (quasi) static picture provided by th ...

Thermal Modeling and Experimental Verification of an Air Cooled Medium Frequency Transformer

Drazen Dujic, Marko Mogorovic

This paper provides detailed analytical modeling and finite elements method (FEM) analysis of the thermal behavior of the medium frequency transformer (MFT). A comprehensive analytical model in form of a thermal network consisting of conduction, convection ...

Quantum limits on measurement and control of a mechanical oscillator

Vivishek Sudhir

The precision measurement of position has a long-standing tradition in physics. Cavendish's verification of the universal law of gravitation using a torsion pendulum, Perrin's confirmation of the atomic hypothesis via the precise measurement of the Brownia ...

Multiscattering-enhanced optical probes for biosensing

Volodymyr Koman

Although reactive oxygen species (ROS) are an inescapable part of every living organism, we are only beginning to understand their functions and mechanics. As of now, we know that ROS are involved in cell signalling, stress-response and defence against pat ...

6 DOF repeatability measurement setup for measuring position of assembled silicon parts with nanometric resolution

Simon Nessim Henein, Florent Cosandier, François Barrot, Johannes Richard Cornelis Geerit Kruis, Pascal Gentsch

This article presents a test setup dedicated to the measurement of the 6 degrees of freedom relative positioning assembly repeatability of three micro-manufactured parts equivalent to those composing a mesoscale flexure-based robot. The typical size of the ...
