Self-alignment of glass spheres using the electromeniscus phenomenon
نویسندگان
چکیده
This letter reports on the self-alignment of glass spheres using a liquid interacting with an electric field for surface modification. The liquid is electrically attracted and trapped between the glass spheres as a result of the electromeniscus phenomenon. The liquid between the spheres removes the electric charge on the spheres, enhances the attractive forces between the spheres, and works as a lubricant for their smooth alignment. These roles of the liquid enable the electric field to smoothly self-assembly glass spheres three-dimensionally. The three-dimensional self-assembly of glass spheres will greatly contribute to the fabrication of micro-optics and biomedical devices using a laser. © 2005 American Institute of Physics.

Acoustics of water saturated packed glass spheres
2014 We have measured the velocity and attenuation of sound in a pack of water saturated glass spheres. The frequency range spreads from 200 kHz to 10 MHz and the diameter of the spheres is varied from 50 03BCm to 500 03BCm. Our experimental data clearly confirm the validity of Biot’s theory of the propagation of sound in porous medium. J. Physique LETTRES 42 (1981) L-477-L-480 Classification P...
متن کاملEffect of Sn Doping on Structural and Optical Properties of 2D α-MoO3 Nanostructures
Undoped and Tin (Sn) doped Molybdenum trioxide (α-MoO3) nanostructured thin films (which has lamellar (2D) structure) have been prepared using a simple and cost effective technique of spray pyrolysis on glass substrates at 450 ℃. Surface morphology, optical and structural properties of samples have been investigated using FESEM, UV-Vis spectroscopy and XRD analysis techniques, respectively. FES...
متن کاملDisk-sphere Transformation in Mammalian Red Cells
THE purpose of this paper is to try to explain the phenomenon of the transformation of the mammalian erythrocytes from disks to spheres when a small drop of a saline suspension is placed between glass slide and cover-glass. Ponder (1934) several years ago reviewed the work which had been done in connexion with this phenomenon. As was pointed out by Ponder, who was the first to show clearly the ...
متن کاملPushing the glass transition towards random close packing using self-propelled hard spheres.
Although the concept of random close packing with an almost universal packing fraction of approximately 0.64 for hard spheres was introduced more than half a century ago, there are still ongoing debates. The main difficulty in searching the densest packing is that states with packing fractions beyond the glass transition at approximately 0.58 are inherently non-equilibrium systems, where the dy...
متن کاملSelf-organized nanogratings in glass irradiated by ultrashort light pulses.
Periodic nanostructures are observed inside silica glass after irradiation by a focused beam of a femtosecond Ti:sapphire laser. Backscattering electron images of the irradiated spot reveal a periodic structure of stripelike regions of approximately 20 nm width with a low oxygen concentration, which are aligned perpendicular to the laser polarization direction. These are the smallest embedded s...
