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...
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 ...
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...
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 ...
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...
Comparative evaluation of powder flow parameters with reference to particle size and shape.
Publication Type: Academic Journal
Source(s): International journal of pharmaceutics [Int J Pharm] 2018 Aug 25; Vol. 547 (1-2), pp. 133-141. Date of Electronic Publication: 2018 May 24.
Abstract: Powder flow is critical to the success of various pharmaceutical processes such as tableting and capsule filling. Despite a plethora of flow characterisation techniques and parameters available, powder flow still remains to be a not well understood sub...
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...
Densification Behavior and Build Quality of Duplex Stainless Steel Fabricated by Laser Powder Bed Fusion.

Assessment of Cytocompatibility and Anti-Inflammatory (Inter)Actions of Genipin-Crosslinked Chitosan Powders.
Publication Type: Academic Journal
Source(s): Biology (2079-7737). Jul2020, Vol. 9 Issue 7, p159. 1p.
Abstract: Chitosan is a polysaccharide commonly used, together with its derivatives, in the preparation of hydrogel formulations, scaffolds and films for tissue engineering applications. Chitosan can be used as such, but it is commonly stabilized by means of che...
How does secondary processing affect the physicochemical properties of inhalable salbutamol sulphate particles? A temporal investigation.
Publication Type: Academic Journal
Source(s): International journal of pharmaceutics [Int J Pharm] 2017 Aug 07; Vol. 528 (1-2), pp. 416-428. Date of Electronic Publication: 2017 Jun 12.
Abstract: As pulmonary drug delivery is extended from low doses to high doses, physicochemical characteristics of the active pharmaceutical ingredient gain importance in the development of dry powder inhalers. Therefore, the present work aims to understand the i...
