Mixing conditions were explored as a possible avenue for improvement of demulsifier performance in solvent diluted bitumen de-watering process. The effects of demulsifier bulk concentration, demulsifier injection concentration and mixing energy on water and solids removal from the oil phase were...

D2 tool steel powders were produced using a drop tube-impulse atomization technique. In order to measure the radiant energy and droplet size of atomized D2 steel droplets, DPV-2000 (Tecnar Automation Ltée, St. Hubert Quebec, Canada) was utilized. In-situ velocity and droplet size of the atomized...

We numerically study different forms of nanoscale gaseous domains on a model for rough surfaces. Our calculations based on the constrained lattice density functional theory show that the inter-connectivity of pores surrounded by neighboring nanoposts, which model the surface roughness, leads to...

Cryopreservation plays a key role in the long-term storage of native and engineered cells and tissues for research and clinical applications. The survival of cells and tissues after freezing and thawing depends on the ability of the cells to withstand a variety of stresses imposed by the...

Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic...

Biologically inert gases play important roles in the biological functionality of proteins. However, researchers lack a full understanding of the effects of these gases since they are very chemically stable only weakly absorbed by biological tissues. By combining X-ray fluorescence, particle...

This paper reports on the quantification of primary dendritic and eutectic nucleation undercoolings during rapid solidification of impulse atomized hypo-eutectic Al-Cu droplets. The procedure consists in determining the eutectic fraction of each investigated droplet from the fraction of...

Poor control of hot strip mill loopers degrades strip width and gauge, and may even lead to mill breakdowns due to instability. In this study, dynamics of the looper-strip system and the control challenges it poses are discussed, and covariance control theory is applied to variance control design...

The assembly of colloidal particles from evaporating suspension drops is seen as a versatile route for the fabrication of supraparticles for various applications. However, drop contact line pining leads to uncontrolled shapes of the emerging supraparticles, hindering this technique. Here we...
