Nanostructured Origami�� describes a method of manufacturing three-dimensional (3D) nanostructures on a silicon wafer. Nanometer-scale structures are best fabricated with various two-dimensional (2D) lithography techniques. This project addresses the problem of building 3D structures using only 2D lithography. The general method of the Nanostructured Origami�� approach involves three steps: lit...

Origami is the centuries-old art of folding paper, and recently, it is investigated as computer science: Given an origami with creases, the problem to determine if it can be flat after folding all creases is NP-hard. Another hundreds-old art of folding paper is a pop-up book. A model for the pop-up book design problem is given, and its computational complexity is investigated. We show that both...

We report a simple method of fabricating graphite nanoribbons by utilizing a self-collapsing mechanism of multi-walled carbon nanotubes during their growth. In the growth process, a nanotube is expelled from a γ-Fe seed nanoparticle, and then collapses spontaneously forming a nanoribbon. Our microscopic analysis of the structures and crystal orientations of γ-Fe nanoparticles and graphite nanor...

In nucleic acid nanotechnology, designed RNA molecules are widely explored because of their usability originating from RNA's structural and functional diversity. Herein, a method to design and prepare RNA nanostructures by employing DNA origami strategy was developed. A single-stranded RNA scaffold and staple RNA strands were used for the formation of RNA nanostructures. After the annealing of ...

Membrane-Mediated Self-Organization of DNA Origami In article number 2101094, Alena Khmelinskaia, Eugene Petrov, and co-workers find surprisingly strong surface-mediated interparticle attraction otherwise repulsive origami particles on locally deformable lipid membranes, resulting in spatial self-organization. On the cover, authors contrast two different worlds (macro nano) with very laws, howe...

We paste together patches of AdS6 to find solutions which describe two 4-branes intersecting on a 3-brane with non-zero tension. We construct explicitly brane arrays with Minkowski, de Sitter and Anti-de Sitter geometries intrinsic to the 3-brane, and describe how to generalize these solutions to the case of AdS4+n, n > 2, where n n + 2-branes intersect on a 3-brane. The Minkowski and de Sitter...

Researchers have been using DNA for the rational design and construction of nanoscale objects for nearly 30 years. Recently, 'scaffolded DNA origami' has emerged as one of the most promising assembly techniques in DNA nanotechnology with a broad range of applications. In the past two years alone, DNA origami has been used to assemble water-soluble probe tiles for label-free RNA hybridization, t...

Software product lines are defined in terms of feature sets that can be orthogonally arranged, according to different design criteria, to constitute dimensions in a design space. When feature sets are well-structured, it is possible to use Origami, a feature-oriented programming technique, to guide feature modelling and composition. However, a considerable manual effort still remains to maintai...
