Powder cohesivity

WebAbstract The permeability of a powder bed reflects its particle size distribution, shape, packing, porosity, cohesivity, and tensile strength in a manner relevant to powder fluidization. The relationship between the permeability and the performance of carrier-based dry powder inhalation (DPI) mixtures has, however, aroused controversy. http://revistafitos.far.fiocruz.br/index.php/revista-fitos/article/download/341/pdf/2289
