Rapid Ascent of Hollow Particles in Water Induced by an Electric Field
Powders, 2023 A novel method has been proposed to induce rapid upward movement of colloidal particles with a density lower than water by applying an electric field of several V/mm in water.

Aging of PA12 Powder in Powder Bed Fusion
Applied 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,

Influence of Powder Deposition on Powder Bed and Specimen Properties [PDF]
Materials, 2019 Three-dimensional printing used to be a rapid prototyping process, but nowadays it is establishing as an additive manufacturing (AM) process. One of these AM techniques is selective laser sintering (SLS), which most often involves partial melting of the particles and therefore belongs to the category of powder bed fusion processes.
