A new type of hybrid colloidal quantum dot/organic solar cells

Solution-processed semiconductors, including materials such as perovskites and quantum dots (i.e., small particles of matter in the quantum size regime), are substances with a conductivity ranging between that of insulators ...

Kirigami designs hold thousands of times their own weight

The Japanese art of origami (from ori, folding, and kami, paper) transforms flat sheets of paper into complex sculptures. Variations include kirigami (from kiri, to cut), a version of origami that allows materials to be cut ...

Researchers make robots from self-folding kirigami materials

Researchers have demonstrated how kirigami-inspired techniques allow them to design thin sheets of material that automatically reconfigure into new two-dimensional (2-D) shapes and three-dimensional (3-D) structures in response ...

Assembler robots make large structures from little pieces

Today's commercial aircraft are typically manufactured in sections, often in different locations—wings at one factory, fuselage sections at another, tail components somewhere else—and then flown to a central plant in ...

Machines that learn language more like kids do

Children learn language by observing their environment, listening to the people around them, and connecting the dots between what they see and hear. Among other things, this helps children establish their language's word ...

Origami, 3-D printing merge to make complex structures in one shot

By merging the ancient art of origami with 21st century technology, researchers have created a one-step approach to fabricating complex origami structures whose light weight, expandability, and strength could have applications ...

Structure

Structure is a fundamental and sometimes intangible notion covering the recognition, observation, nature, and stability of patterns and relationships of entities. From a child's verbal description of a snowflake, to the detailed scientific analysis of the properties of magnetic fields, the concept of structure is an essential foundation of nearly every mode of inquiry and discovery in science, philosophy, and art.

A structure defines what a system is made of. It is a configuration of items. It is a collection of inter-related components or services. The structure may be a hierarchy (a cascade of one-to-many relationships) or a network featuring many-to-many relationships.
