Pinch valves are operated by squeezing a flexible tube in a part of the valve by either moving a separate squeezing device against the tube or by impinging the squeezing part with an actuator. However, with current state of the art valves it is necessary to manually insert the tube between the squeezing device and the counter bearing which is in most cases rather complicated. Besides this, most of the pinch valves are as well pretty large and cannot be used in miniaturized or highly integrated systems. Thus the secure dosing of liquids that contain cells or other solids is with the currently available valves only possible when using exchangeable pinch valves.<br><br> <strong>Technology</strong><br> HScientist at the Technische Universität Berlin have now developed a pinch valve that overcomes the current disadvantages of the state of the art as it can be integrated into existing dosing systems as inexpensive single use valve.<br><br> It allows dosing very little amounts of liquid in a very fast, precise and highly dynamic way. As the valve is modularly constructed it allows an inexpensive mass production via injection molding, is easily adaptable to various applications and can be automatized mounted. Moreover it is uncomplicated to incorporate the valve into existing dosing systems without great effort. <br><br> For further information please see also the following link: http://www.process.vogel.de/index.cfm?pid=7085&pk=336319&print= (article in German)

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
