چکیده
The basic structures for linking squares into polyhedra and networks (reticulation) are enumerated, and corresponding examples are described in which crystals were synthesized by linking paddle wheel (square) units into metal-organic frameworks (MOFs)--named MOF-102 to MOF-112.

Assembly by Intelligent Scaffolding ; CU-CS-1080-11
We propose a novel class of algorithms for autonomously assembling structures from inert building blocks guided by intelligent scaffolding components. Intelligent scaffold units are equipped with sensing, actuation, computation and communication abilities and facilitate the attachment of inert building blocks to the structure. After attaching an inert building block, the scaffold structure reco...

متن کاملDiamondoids and DNA Nanotechnologies
Diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. The Diamondoids family of compounds is one of the best candidates for molecular building blocks (MBBs) in nanotechnology to construct organic nanostructures compared to other MBBs known so far. The challenge is to find a route for self-assembly of these cage hydrocarbons and their applications in the bottom-...
متن کاملANT COLONY ALGORITHMS FOR NONLINEAR ANALYSIS AND OPTIMAL DESIGN OF STRUCTURES
In this paper nonlinear analysis of structures are performed considering material and geometric nonlinearity using force method and energy concepts. For this purpose, the complementary energy of the structure is minimized using ant colony algorithms. Considering the energy term next to the weight of the structure, optimal design of structures is performed. The first part of this paper contains ...
