Acoustic Trapping of Bacteria and Nanoparticles in Disposable Glass Capillaries Using Seed Particles
This paper describes a novel method for acoustic trapping of submicron particles in glass capillaries using secondary acoustic forces. By using preloaded larger particles (seed particles) to initiate clustering, trapping of submicron particles is greatly improved and can be accomplished at lower concentrations. As a potential application for this new method we demonstrate capture and enrichment...
Formation, properties, transformations, and temporal evolution of secondary organic aerosol (SOA) particles depend strongly on SOA phase. Recent experimental evidence from both our group and several others indicates that, in contrast to common models' assumptions, SOA constituents do not form a low-viscosity, well-mixed solution, yielding instead a semisolid phase with high, but undetermined, v...
Objective of this study is to investigate the effect secondary motion particles in multiphase gas-solid flows parametrically and test relative impacts particle shape orientation information on distribution. For that purpose, predictive accuracies simplified drag coefficient models are assessed for conditions relevant a wood recovery plant operating at dilute flow regime. After demonstrating str...
The heterogeneous structure of Al alloys renders them susceptible to localized corrosion due to the different electrochemical properties existing in the Al-rich solid solution matrix and secondary phase particles. The galvanic interactions between these two phases can result in pit formation either through dissolution of the particles or corrosion of the matrix adjacent to the particles. This d...
Time-resolved single-particle measurements were conducted during Chinese New Year in Nanning, China. Firework displays resulted in a burst of SO2, coarse mode, and accumulation mode (100-500nm) particles. Through single particle mass spectrometry analysis, five different types of particles (fireworks-metal, ash, dust, organic carbon-sulfate (OC-sulfate), biomass burning) with different size dis...
