Characterization of copper & stainless steel interface produced by electron beam powder bed fusion

Materials & Design, 2021
Unalloyed copper (Cu) powder was deposited and melted onto a pre-existing stainless steel substrate using electron beam powder bed fusion (EB-PBF) additive manufacturing (AM) to form dense, bimetallic structures. The AM fabricated Cu was fully dense, and

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

Advanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...
