Origami Inspired Self-assembly of Patterned and Reconfigurable Particles
There are numerous techniques such as photolithography, electron-beam lithography and soft-lithography that can be used to precisely pattern two dimensional (2D) structures. These technologies are mature, offer high precision and many of them can be implemented in a high-throughput manner. We leverage the advantages of planar lithography and combine them with self-folding methods(1-20) wherein ...
متن کاملSynthesis and directed self-assembly of patterned anisometric polymeric particles.
A simple and versatile method for making chemically patterned anisotropic colloidal particles is proposed and demonstrated for two different types of patterning. Using a combination of thermo/mechanical stretching followed by a wet chemical treatment of a sterically stabilized latex, both patchy ellipsoidal particles with sticky interactions near the tips as well as particles with tunable fluor...
متن کاملPreparing nurses for retirement: A concept analysis
Background and Purpose: Retirement is an important event in nurses’ life. Preparation and planning are the essential necessities before nurses get retired. Healthcare leaders play an important role in preparing nurses for retirement. This study aims to explore the process by which nurses were prepared for retirement. Methods: The theory development method according to Walker and Avant was...
متن کاملConjunctival Pockets.
SYMBLEPHARON is described by all authors discussing conjunctival diseases as adhesion between the palpebral and bulbar conjunctivae. Its aetiology is described as purulent conjunctivitis, diphtheritic conjunctivitis, trachoma, trauma, and so on. These factors do not always cause symblepharon, but may result in a very troublesome condition, apparently not mentioned in the literature, viz. conjun...
متن کاملAn AC electrokinetic technique for collection and concentration of particles and cells on patterned electrodes.
We report an electrohydrodynamic effect arising from the application of alternating electric fields to patterned electrode surfaces. The AC fields were applied to dilute suspensions of latex microspheres enclosed between a patterned silicon wafer and an ITO-coated glass slide in a small chamber. The latex particles became collected in the center of the conductive "corrals" on the silicon wafer ...
