• Flow electrodes may enable large-scale sea water desalination

  Across the world, millions of people cannot access fresh, clean water. With global populations rising and freshwater supplies regularly becoming overdrawn or contaminated, the ability to purify sea water is becoming increasingly important. Now, scientists from South Korea have modified a water treat more

• Pyroelectric nanogenerator charges Li-ion battery with harvested energy

  The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very large more

• Pumps for Spanish particle accelerator

  The Spanish KSB Group company KSB ITUR was awarded a contract for the supply of 57 cooling pumps to be used in a particle accelerator known as “Synchrotron Alba” which is currently under construction. The pumps are process pumps designed for flow rates of up to 646 cubic metres and a maximum discha more

• VACUU•LAN® Vacuum Local Area Networks
  

  In modern chemical and pharmaceutical lab buildings vacuum supply has become a standard for each work station, just as water or gas supply. Therefore vacuum supply solutions are considered at earliest stage for new laboratory buildings and are fully integrated in the planning and layouting procedure in many cases. Demands for vacuum vary over a wide range of applications – e.g. evaporation, distillation, vacuum drying, or simply filtration and aspiration. All of these can be covered well by Chemistry Diaphragm Pumps more

• Innovative column technology for liquid chromatography
  

  Fast, efficient and cost saving chromatography of various samples by application of a liquid stationary phase. Termination of disadvantages of the solid phase material used in classical chromatography. more

• Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS
  

  The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increased almost twentyfold from 54 to 1015. As active compounds these products contain ZnO for surface protection, TiO2 for sun screen or Ag for anti-bacterial purposes, only to name a few applications. Furthermore, Si, C and Au are frequently used. So far, no data are available concerning the release and the behaviour of nanoparticles during the spray process. Therefore, in spite of their beneficial properties, possible risks for humans and the environment need to be thoroughly investigated. Especially the exposure pathway via the lung seems to be very critical, as could be shown in a study recently published in the Journal of Nanoparticle Research more

• Catalytic oxidation of CO by N2O conducted via the neutral oxide cluster couple VO2/VO3

  Neutral vanadium and cobalt oxide clusters are generated at the same time employing a V–Co mixed target. Experimental results indicate that the reaction VO2 + N2O → VO3 + N2 occurs in a fast flow reactor. This interpretation is further supported for a gas mixture of CO and N2O in the flow cell: rege more

• Advances in low temperature gas-phase kinetics

  Rate constants for elementary gas-phase reactions were first measured reliably following the development of pulsed photolysis and flow methods in the 1960's. These techniques have continued to be employed as kinetics experiments have been performed at lower and lower temperatures. Sub-ambient temper more

• Cardiac-like flow generator for long-term imaging of endothelial cell responses to circulatory pulsatile flow at microscale

  In vitro models of circulatory hemodynamics are required to mimic the microcirculation for study of endothelial cell responses to pulsatile shear stress by live cell imaging. This study reports the design, fabrication and characterisation of a microfluidic device that generates cardiac-like flow in more
