1. Particle dynamics during biomass devolatilization : Momentum exchange and particle dispersion
Abstract : Devolatilization is a heat-driven thermochemical process in which a liquid or a solid fuel releases mass in the form of volatile compounds after drying, as a result of the combination of endothermic and exothermic reactions. It differs from pyrolysis in that it does not require an inert atmosphere and that the reactant must be either solid or liquid. READ MORE

2. On Particle Transport and Turbulence Modification in Air-Particle Flows
Abstract : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. READ MORE

3. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth
Abstract : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). READ MORE

5. Approaches to particle acceleration in intense laser-matter interaction
Abstract : In the interaction of ultra-intense laser fields with matter, the target is rapidly ionized and a plasma is formed. The ability of a plasma to sustain acceleration gradients, orders of magnitude larger than achievable with conventional accelerators, has led to a great interest in laser-driven plasma-based particle acceleration and radiation generation, with applications in materials science, biology and medicine.
