Inhalation of pirfenidone is one the possible methods for effective treatment idiopathic pulmonary fibrosis. In this study, we attempted to prepare inhaled dry powder through reasonable design precursor formulation and parameter adjustment spray drying process. The mechanism polyvinyl alcohol (PVA) polymer as surfactant used assist dissolution in water, instead using organic solvents (such etha...

In recent years, the rolling densification process has become increasingly widely used to strengthen powder metallurgy parts. The original composition of the rolled powder metallurgy blank has a significant effect on the rolling densification technology. The present work investigated the effects of different carbon contents (0 wt. %, 0.2 wt. %, 0.45 wt. %, and 0.8 wt. %) on the rolling densific...

The dried fruit of Terminalia chebula is widely used for its laxative properties. The objective of the present study was to examine the flowability and compressibility of Terminalia chebula fruit powder, subsequently developing its tablet formulations by utilizing wet granulation and direct compression technology. Initial studies on flowability and compressibility revealed that the fruit powder...

A potential way of improving the material efficiency and cost effectiveness of the Direct Metal Laser Deposition (DMLD) process is to take powder that is not utilised in each deposition attempt and re-use it in subsequent attempts (powder recycling). Currently, this is not widely implemented for fear of a detrimental effect on part quality. This study examines how powder recycling, using simple...
