Getter sputtering system for high-throughput fabrication of composition spreads.
We describe a sputtering system that can deposit composition spreads in an effectively UHV environment but which does not require the high-throughput paradigm to be compromised by a long pump down each time a target is changed. The system deploys four magnetron sputter guns in a cryoshroud (getter sputtering) which allows elements such as Ti and Zr to be deposited with minimal contamination by ...
متن کاملInsulin pumps.
I nsulin pump therapy—continuous subcutaneous insulin infusion (CSII)—was developed in the UK in the 1970s. Rapid technological developments changed the initial pumps from the size of a house brick, charged by mains electricity to an acceptable dimension, battery driven. We described the use of pumps in young people with type 1 diabetes (T1D) in the UK in Archives of Disease in Childhood in the...
متن کاملComparing pumps.
Comparative evolutionary studies have greatly aided our understanding of how the heart develops. Two recent articles from Benoit Bruneau’s laboratory reveal the power of the so-called evo-devo approach and provide yet further details of development, both of the heart itself and of the cells that build it. Thanks to our many and varied primitive cousins, developmental biologists are gaining a go...
متن کاملPeristaltic Pumps
Peristaltic pumps are mechanical displacement pumps that induce flow in a fluid-filled, flexiblewalled conduit through peristalsis – transport due to traveling contraction waves. While macroscale peristaltic pumps appear in a variety of configurations, micropumps based on this principle almost exclusively use the sequenced contraction and expansion of a small number of discrete actuators – typi...
متن کاملPumps in wearable ultrafiltration devices: pumps in wuf devices.
The wearable artificial kidney (WAK) is a device that is supposed to operate like a real kidney, which permits prolonged, frequent, and continuous dialysis treatments for patients with end-stage renal disease (ESRD). Its functioning is mainly related to its pumping system, as well as to its dialysate-generating and alarm/shutoff ones. A pump is defined as a device that moves fluids by mechanica...
