In this work, ZnO nanoparticle resistive sensors decorated with rare earths (REs; including Er, Tb, Eu and Dy) were used at room temperature to detect atmospheric pollutant gases (NO2, CO and CH4).Sensitive films were pentair hose prepared by drop casting from aqueous solutions of ZnO nanoparticles (NPs) and trivalent RE ions.The sensors were conti
Influenza A viruses are often present in environmental and clinical samples at concentrations below the limit of detection (LOD) of molecular diagnostics.Here we report an integrated microfluidic preconcentration and nucleic amplification read more system (μFPNAS) which enables both preconcentration of influenza A virus H1N1 (H1N1) and amplifi
The evolution of aggregate (floc) size distributions resulting from hydrophobic flocculation has been investigated using a laser light scattering technique.By measuring floc size distributions it is possible to distinguish clearly among floc formation, growth and breakage.Hydrophobic flocculation of hematite suspensions with sodium oleate under a v
