Simulation of superresolution holography for optical tweezers [PDF]

, 2008
Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

A time-variant reliability analysis framework for selective laser melting fabricated lattice structures with probability and convex hybrid models

Virtual and Physical Prototyping, 2022
We propose a time-variant reliability analysis framework to quantitatively predict the lifetime of the lattice structures fabricated by selective laser melting (SLM), including confirming hybrid uncertainties, establishing a hybrid model, and proposing ...

The stability of supported liquid membranes [PDF]

, 1990
In this paper a new hypothesis about the instability mechanism of SLMs will be discussed: emulsion formation induced by lateral shear forces. Experimental results show that a water phase with a low salt concentration which flows along the membrane ...
