Understanding the formation of powder bed cavities in paving by the van der Waals force

Journal of Materials Research and Technology
Powder-bed-fusion (PBF) additive manufacturing of high-performance alloys (e.g. GH3536) necessitate stringent control of powder bed quality to mitigate defects, particularly cavities that compromise component integrity.

Temperature-Dependent van der Waals Forces

Biophysical Journal, 1970
Biological systems can experience a strong van der Waals interaction involving electromagnetic fluctuations at the low frequency limit. In lipid-water mixtures the free energy of this interaction is proportional to temperature, primarily involves an entropy change, and has qualitative features of a "hydrophobic bond." Protein-protein attraction in ...

MICRO-MATERIAL HANDLING, EMPLOYING E-BEAM COATINGS OF COPPER AND SILVER

South African Journal of Industrial Engineering, 2012
<p>ENGLISH ABSTRACT: Van der Waals forces and other adhesive forces impose great challenges on micro-material handling. Mechanical grippers fail to release micro-parts reliably because of them.

Surface enhanced van der Waals force [PDF]

Physica Scripta, 2009
We consider the van der Waals interaction of an excited atom and a ground state atom across a vacuum-medium interface under the circumstances of the resonant coupling of the excited atom to a surface polariton mode of the system. We demonstrate that the nonretarded interaction potential between the atoms is in this case the same as in an effective ...
