Enhanced Permeability of Fe-Based Amorphous Powder Cores Realized through Selective Incorporation of Carbonyl Iron Powders at Inter-Particle Voids.
Publication Type: Academic Journal
Source(s): Metals (2075-4701). Aug2021, Vol. 11 Issue 8, p1220. 1p.
Abstract: In this study, we demonstrate a hybrid multimodal soft magnetic composite (SMC) comprising gas-atomized spherical amorphous powder (AP) and carbonyl-iron powder (CIP), and present its enhanced electromagnetic properties. CIP is selectively incorporated...
Tailoring characteristic thermal stability of Ni-Au binary nanocrystals via structure and composition engineering: theoretical insights into structural evolution and atomic inter-diffusion.
Publication Type: Academic Journal
Source(s): AIP Advances. 2014, Vol. 4 Issue 11, p1-9. 9p.
Abstract: We report on the structural evolution and atomic inter-diffusion characteristics of the bimetallic Ni-Au nanocrystals (NCs) by molecular dynamics simulations studies. Our results reveal that the thermal stability dynamics of Ni-Au NCs strongly depends ...
Nanoparticle Additivation Effects on Laser Powder Bed Fusion of Metals and Polymers—A Theoretical Concept for an Inter-Laboratory Study Design All Along the Process Chain, Including Research Data Management.
Publication Type: Academic Journal
Source(s): Materials (1996-1944). Sep2021, Vol. 14 Issue 17, p4892. 1p.
Abstract: In recent years, the application field of laser powder bed fusion of metals and polymers extends through an increasing variability of powder compositions in the market. New powder formulations such as nanoparticle (NP) additivated powder feedstocks are...
Prediction of Inter-particle Adhesion Force from Surface Energy and Surface Roughness.
Publication Type: Academic Journal
Source(s): Journal of Adhesion Science & Technology. 2011, Vol. 25 Issue 4/5, p367-384. 18p. 1 Black and White Photograph, 3 Charts, 7 Graphs.
Abstract: Fine powder flow is a topic of great interest to industry, in particular for the pharmaceutical industry; a major concern being their poor flow behavior due to high cohesion. In this study, cohesion reduction, produced via surface modification, at the ...
Identification of inter-particular forces by atomic force microscopy and how they relate to powder rheological properties measured in shearing tests.
Publication Type: Academic Journal
Source(s): Powder Technology. Nov2015, Vol. 284, p396-402. 7p.
Abstract: In this study, we used atomic force microscopy (AFM) to measure and identify the nature of the forces acting between single pharmaceutical powder particles, namely a crystalline and a semi-crystalline form of lactose. The experiments done at different ...
Quantifying stress-induced anisotropy using inter-void constrictions.
Publication Type: Academic Journal
Source(s): Géotechnique. Jan2013, Vol. 63 Issue 1, p85-91. 7p.
Abstract: In particulate geomechanics it is common to quantify fabric anisotropy using contact and particle orientations. Measurement of void anisotropy is less common, most likely owing to the difficulties associated with defining individual voids. Here a Delau...
Analysis of Au-Ag Mineralization in the Caribou Base-Metal VMS Deposit, New Brunswick; Examination of Micro-Scale Inter- and Intra-Sulphide Distribution and Its Relation to Geometallurgy.
Publication Type: Academic Journal
Source(s): Minerals (2075-163X). Dec2016, Vol. 6 Issue 4, p113. 25p.
Abstract: The Caribou Zn-Pb-Cu-Ag volcanogenic massive sulphide deposit located in northeast New Brunswick represents a significant base-metal resource in the Bathurst Mining Camp. Zinc, Pb and Cu are the primary resources that are being extracted from this depo...
Improving deposition efficiency and inter-particle bonding of cold sprayed Cu through removing the surficial oxide scale of the feedstock powder.
Publication Type: Academic Journal
Source(s): Surface & Coatings Technology. Feb2021, Vol. 407, pN.PAG-N.PAG. 1p.
Abstract: In cold spray, surficial oxide scale of the feedstock powder not only reduces the deposition efficiency of spraying powder, but also deteriorates the properties of the deposit due to its influence on inter-particle bonding. To simultaneously improve th...

Publication Type: Academic Journal
Source(s): Metals (2075-4701). Apr2023, Vol. 13 Issue 4, p741. 15p.
Abstract: A systematic study on the densification behavior and build quality of 2205 duplex stainless steel fabricated using laser powder bed fusion (LPBF) was performed by experiment and simulation, aiming to offer some supplementary work for research on additi...
Estimating inter-patient variability of dispersion in dry powder inhalers using CFD-DEM simulations.
Publication Type: Academic Journal
Source(s): European Journal of Pharmaceutical Sciences. Jan2021, Vol. 156, pN.PAG-N.PAG. 1p.
Abstract: Drug delivery from a capsule-based dry powder inhaler depends on the inhaler's design, the drug's formulation, and the inhalation maneuver. The latter affects both the air flow and the capsule motion in the inhaler. It is well known that patient-to-pat...
