Atmospheric particle number size distributions (size range 0.003–10μm) were measured between March 2008 and August 2009 at Shangdianzi (SDZ), a rural research station in the North China Plain. These measurements were made in an attempt to better characterize the tropospheric background aerosol in Northern China. The mean particle number concentrations of the total particle, as well as the nucle...

An experimental study concerning particle behaviors in a horizontal dilute swirling flow pneumatic conveying was performed. Measurements of particle velocities and concentration profiles have been carried out using the photographic image technique. From the experimental results, it is found that mean particle velocity of swirling flow pneumatic conveying is lower than that of conventional pneum...

Long-term measurements (over 4 years) of particle number size distributions (submicrometer particles, 3– 800 nm in diameter), trace gases (NO, NO2, and O3), and meteorological parameters (global radiation, wind speed and direction, atmospheric pressure, etc.) were taken in a moderately polluted site in the city of Leipzig (Germany). The resulting complex data set was analyzed with respect to se...

Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...

The gelatin/gum Arabic microcapsules encapsulating peppermint oil were prepared by complex coacervation using tannic acid as hardening agent. The effects of various parameters, including concentration of wall material, core material, tannic acid and tween80 were investigated on particle size and encapsulation efficiency. For statistical evaluation of the parameters, Taguchi method has been used...

This paper presents a review and analysis of the research that has been carried out on dynamic calibration for optical-fiber solids concentration probes. An introduction to the optical-fiber solids concentration probe was given. Different calibration methods of optical-fiber solids concentration probes reported in the literature were reviewed. In addition, a reflection-type optical-fiber solids...

An investigation into the optimisation of a highly-concentrated (20 wt%) and stable platinum (Pt) organometallic ink, showing consistent jetting performance whilst minimising negatives associated with particle-containing inks. The ink was synthesised printing demonstrated onto glass by piezoelectric drop-on-demand inkjet printer. Stable rapid (Z number: 1.83, 8 m/s) achieved using cyclohexanol-...
