Soft Periodic Microstructures Containing Liquid Crystals

The Journal of Physical Chemistry B, 2013
An empty polymeric structure has been realized by combining a high precision level optical holographic setup and a selective microfluidic etching process. The distinctive features of the realized periodic microstructure enabled aligning several kinds of liquid crystal (LC) compounds, without the need of any kind of surface chemistry or ...

Composites with periodic microstructure

Computers & Structures, 1983
For an elastic body containing periodically distributed inhomogeneities, a general procedure is developed for estimating the overall properties of the composite in terms of several infinite series which, for the isotropic matrix (but anisotropic inclusions), depend only on the geometry of the inhomogeneities and hence can be calculated once and for all

Periodic and aperiodic superconducting microstructures

SPIE Proceedings, 1998
Abstract We summarize some recent activities of our group involving e-beam and optically patterned,Nbbased, superconducting nanostructures, as well as related computer modeling studies. Thedevices described are: i) Fiske cavities buried in a Nb base layer and driven by an overlyingNb/AlOx/Nb Josephson oscillator junction, ii) Nb/AlOx/AIJAIOx/Nb (SINIS)

Preparation of Periodic Microstructured Diamond Surfaces

Chemistry Letters, 2000
Abstract Two types of periodic surfaces were fabricated by utilizing two-dimensionally ordered arrays, in one case as a template and in another as a mask. In the first case, a bulb-like microstructured surface was formed, and, in the second, a cylinder-like microstructure.

Analysis of Periodical Microstructures Using Optical Methods

Advanced Materials Research, 2012
In this work we present an optical laser based method for characterization of periodical microstructure. It allows indirect evaluation of geometrical and optical parameters of periodical microstructures. Proposed method is applicable for optimization and control of technological processes in the cases when traditional measurement techniques are not ...

Periodic Area Minimization Surfaces in Microstructural Science

MRS Proceedings, 1989
AbstractAn A/B block copolymer consists of two macromolecules bonded together. In forming an equilibrium structure, such a material may separate into distinct phases, creating domains of component A and of component B. A dominant factor in the determination of the domain morphology is area-minimization of the intermaterial surface, subject to fixed ...

Periodic magnetic microstructures by glancing angle deposition

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2000
An advanced deposition technique known as glancing angle deposition (GLAD) [K. Robbie, J. C. Sit, and M. J. Brett, J. Vac. Sci. Technol. B 16, 1115 (1998); K. Robbie and M. J. Brett, U.S. Patent No. 5,866,204 (filed 1999)] has been used to fabricate periodic arrays of magnetic pillars and randomly seeded magnetic helices, posts, and chevrons.
