A powder pycnometry method, using a commercially available instrument (GeoPyc® with DryFlo® displacement media), was evaluated as a means of measuring the envelope density of hydroxyapatite (HA) ...

True density is commonly measured using helium pycnometry. However, most water-containing powders, for example, hydrates, amorphous drugs and excipients, and most tablet formulations, release water ...

ABSTRACT: The ultrastructure and physicochemical and thermal properties of Palm Kernel Shells (PKS) in comparison with Coconut Kernel Shells (CKS) were investigated herein. Powder samples were ...

ABSTRACT: Waste management after coconut harvesting is a real problem at a national level. Coconut production in Benin increases considerably every year, especially in the coastal and Atlantic ...
