Feb. 3, 2012, 12 p.m. - Microfluidic drops as biological and chemical reactors (Charles Baroud)

I will present two approaches that we have developed to create and manipulate microfluidic drops, with the aim of performing chemical and biological tests. The drops, which range in volume from 10 pL to 100 nL, can be created, sorted, or arrayed using a combination of simple tools. This provides ...

Feb. 10, 2012, 12 p.m. - Manufacturing Core-Shell Nanoparticles by Atomic Layer Deposition in a Fluidized Bed (Ruud van Ommen)

Core-shell nanoparticles have high potential in heterogeneous catalysis, energy storage, and medical applications. Currently, such particles are mainly synthesized in the liquid phase. However, gas phase methods offer several inherent advantages: (1) the absence of solvent waste; (2) a clean particle surface which may be desirable for applications such as ...

Feb. 17, 2012, 12 p.m. - Process Design via CFD Analysis in Carbothermic Aluminium and Slag Fiberization (Dimitrios I. Gerogiorgis)

A plethora of novel chemical processes of extreme industrial importance at various sizes cannot be reliably designed via standard modeling simplifications, because accurate models must rely on nonlinear PDE systems describing spatiotemporal variation, flow and reactions. Further challenges perplexing modeling efforts may include poor understanding of physics, high CPU cost ...

Feb. 24, 2012, 12 p.m. - Global guidance principles for Life Cycle Assessment databases (Guido Sonnemann)

Global guidance principles for Life Cycle Assessment (LCA) databases have been published by a group of leading experts from around the world under the leadership of the United Nations Environment Programme (UNEP) and the Society of Environmental Toxicology and Chemistry (SETAC). The guidance includes how to collect raw data, how ...
