  • Electronic transport across hydrogen bonds in organic electronics

    Hydrogen bonds (H–bonds) are relatively weak and result from non–covalent interactions. Despite their relatively low strength compared to other bonds of biochemical relevance, they play a vital role in determining the structure and function of biological molecules owing to their directionality and cooperativeness. This has led to an intense effort in harnessing the properties of these hydrogen ...

  • Numerical simulation of coolant mixing in a pressurised water reactor with different CFD methods based on complex meshes

    This paper describes the numerical simulation of coolant mixing in the downcomer and the lower plenum of the Rossendorf test facility, ROCOM. ROCOM is a 1:5 scale Plexiglas model of a German pressurised water reactor, allowing conductivity measurements by wire mesh sensors and velocity measurements by the LDA technique. The CFD calculations were carried out with the CFD codes CFX-4 and CFX-5. In ...

  • Long-Term Water Quality Monitoring Deployments with the Sea-Bird Hydrocat-Ep - Case Study

    The new Sea-Bird Scientific HydroCAT-EP incorporates a suite of physical and biogeochemical sensors into a single, robust instrument designed to maximize water quality parameters and give sustained accuracy. The instrument uses the same high quality Sea-Bird and WET Labs sensors found on their industry    leading    CTDs    and    ocean ...

  • Impact parameters investigation of DNA immobilisation process on DNA sensor response

    This paper studies impact parameters of DNA sequence immobilisation on DNA sensor response. The parameters were examined including immobilisation time, carbon nanotubes concentration, DNA probe concentration and pH value. The DNA probe sequences were immobilised on surface of microelectrodes by using multi–walled carbon nanotubes (MWCNTs) as mediator. The hybridisation between DNA probe and DNA ...

  • Characterization of water pollution in drainage networks using continuous monitoring data in the Citadel area of Hue City, Vietnam

    In the Citadel area of Hue City, drainage systems that include canals and ponds are considerable sources of fecal contaminants to inundated water during the rainy season because canals and ponds receive untreated wastewater. It is important to investigate the characteristics of hydraulics and water pollution in canals and ponds. At the canals and ponds, water sampling was conducted during dry ...

  • Rogowski Coil Current Sensing Method

    In an earlier blog post, we introduced the 6 different current sensing methods used in the current meters and sensors developed by Hioki. Here, we highlight the Rogowski coil method that enables the design of flexible sensors through the use of an air core (or coreless) structure. In a Rogowski sensor, there is no heat ...
