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)

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
