Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) have recently been recognized as important techniques for R&D of products and processes, as is attested by several successful applications in different areas of chemical engineering in recent years. In this article we present new experimental methods based on MRI to study flow and microstructure of concentrated emulsions. The...

Non homogeneous particle distribution is one of the greatest problems in casting Metal Matrix Composites (MMC's). To optimize some of the parameters for uniform particle distribution for batch compocasting the present simulation studies were conducted. The simulation involves visualisation experiments. In the visualisation experiments liquid and semi solid aluminium are replaced by other fluids...

The role of vegetation in mitigating the effects of PM(10) pollution has been highlighted as one potential benefit of urban greenspace. An integrated modelling approach is presented which utilises air dispersion (ADMS-Urban) and particulate interception (UFORE) to predict the PM(10) concentrations both before and after greenspace establishment, using a 10 x 10 km area of East London Green Grid ...

The particulate matter (PM) concentration and composition, the PM10, PM2.5, PM1 fractions, were studied in the urban area of Genoa, a coastal town in the northwest of Italy. Two instruments, the continuous monitor TEOM and the sequential sampler PARTISOL, were operated almost continuously on the same site from July 2001 to September 2004. Samples collected by PARTISOL were weighted to obtain PM...

The route for single step synthesis and encapsulation of a model hydrophilic drug onto homogeneous microparticles for controlled release applications is described. The microfluidic spray drying technique, able to handle complex fluids, was used to produce uniform particles with adjustable functionality. Here, an aqueous polymeric dispersion of Eudragit NE was used as the controlled release matr...

For the past few years, there has been a considerable research on the basis of Novel drug delivery system, using particulate vesicle systems as such drug carriers for small and large molecules. Nanoparticles, Liposomes, Microspheres, Niosomes, Pronisomes, Ethosomes, Proliposomes have been used as drug carrier in vesicle drug delivery system. Various polymers have been used in the formation of N...

Background: We present a Support Vector Machine (SVM) approach to the localization of hazardous particulate releases in an urban area using features constructed only from measurements obtained from a network of sensors. Results: We find high levels of localization accuracy when a reasonable number of noisy sensors are deployed within the environment. We also compare SVM source localization perf...

In the region of minimum porosity of particulate binary mixtures, heat exchange and permeability were found to be higher than the ones obtained with a mono-size packing built with the same small size particles used in the binary packing. This effect was noticed in the range of the particles size ratio 0.1–1.0. The obtained improvement on thermal performance is related to the increase of effecti...

The aim of the present study was to evaluate the possible association between occurrence of soft tissue sarcomas in Verona (Italy) and residence near a steel foundry, whose emissions of dioxin-like compounds may be relevant. Exposure to total suspended particulate (TSP) emitted from the plant as estimated by ADMS-urban dispersion model was used as an indirect index of exposure to dioxin-like co...

Theoretical background for SAXS analysis In view of our TEM observations (Figure 2) and previously reported SAXS data obtained for a PLMA16PBzMA37 solution in n-dodecane1, it was assumed that the SAXS patterns corresponded to (i) a pure worm phase (Figure 4a) for the dilute PLMA16-PBzMA37 dispersion and (ii) spherical aqueous droplets stabilised by a layer of adsorbed worms for the concentrated...
