The physics of wind-blown sand and dust (2012, background): “When granular particles such as dust and sand are brought into contact, they are subjected to several kinds of cohesive interparticle forces, including van der Waals forces, water adsorption forces and electrostatic forces (e.g. Castellanos 2005).”
An overview of powder granulometry on feedstock and part performance in the selective laser melting process (2017, background): “Powder cohesivity is dependent on its inter-particle forces (Fi) and particle weight (mg) according to the granular bond ratio (BN = Fi mg ⁄ ) previously defined by [106].”
Scaling forces to asteroid surfaces: The role of cohesion (2010, methodology): “Castellanos studies the effects of surface asperities and the inclusion of relatively small particles within printing toners and analytically characterizes their effects on cohesive forces [8].”
Powder flowability characterisation methodology for powder-bed-based metal additive manufacturing (2016, background): “It is well known that a high amount of fine particles does negatively affect the flowability of a powder, as for fine particles the cohesive granular bond number (BN) [12] becomes high.”
The strength of regolith and rubble pile asteroids (2013, background): “In terrestrial settings, these forces and their effects are only significant at particle sizes below 100 lm, and become dominant for powders of size <10 lm (Castellanos 2005).”
The Physics of Sediment Transport Initiation, Cessation, and Entrainment Across Aeolian and Fluvial Environments (2020, background): “Cohesive interparticle forces, including van der Waals [Castellanos, 2005], water adsorption [Herminghaus, 2005], and electrostatic forces [Lacks and Sankaran, 2011], become significant in the collision process for sufficiently small particles (on Earth, for d .”
