  • Analysers and next generation SRU control

    The history of on-line process analytics is a relatively short one. Development was driven by the need for process control of high value hydrocarbonbased products. The first on-line analyser applications came during the second war. Rapid development came in the 1970s with the advent of the microprocessor and resultant chemometric techniques. Led by Phillips Petroleum, Union Carbide and Dupont ...

  • Gold nanoparticles functionalised with Ru–dicarboxybipyridine–trimercaptotriazine: SERS effect and application in plasmonic dye solar cells

    A dicarboxybipyridine–trimercaptotriazine ruthenium complex, primarily designed for dye–sensitised solar cells (DSSC), has been successfully employed in the generation of electrostatically stabilised gold colloids, because of its high negative charge and capability of binding to gold nanoparticles via the sulphur groups. Strong SERS enhancements have been obtained for the isolated gold ...

  • Effect of sulfate and lactate loading rates on the respiration process and microbial population changes measured by ecological indices

    In a sulfate reducing process, increasing loading rates and sulfide accumulation may induce population changes resulting in decreasing effectiveness of the process. Thus, the relationship between microbial metabolism changes and population dynamics was studied. An upflow anaerobic sludge blanket reactor was operated at different sulfate loading rates (SLR), from 290 to 981 mg SO4 − S/L d ...
