Nano–Crystalline Mn–Ni–Co–O Thermistor Powder Prepared by Co–Precipitation Method

open access: yesPowders, 2023
Here, we demonstrate that nano–sized Mn–Ni–Co–O powder can be prepared at a low temperature via a co–precipitation method. In this work, Mn2+ was partially oxidized to Mn3+ ions in an aqueous solution by adding an oxidizing agent (H2O2).

Vibratory Powder Feeding for Powder Bed AdditiveManufacturing using Water and Gas Atomized MetalPowders [PDF]

open access: yes, 2021
Commercial powder bed fusion additive manufacturing systems use recoaters for the layer-by-layer distribution of powder. Despite the known limitations of recoaters, there has been relatively little work presented on the possible benefits of alternative powder delivery systems.

Aging of PA12 Powder in Powder Bed Fusion

open access: yesApplied Sciences, 2023
Powder Bed Fusion (PBF) is a popular additive manufacturing technology due to its high build resolution and ability to produce microscale geometries without the use of additional support. Despite the many benefits of PBF, there are still some limitations associated with the materials to be built. A critical industrial limit is the aging of PA12 powder,
