Solar cell material can assist self-driving cars in the dark

Material used in organic solar cells can also be used as light sensors in electronics. This has been shown by researchers at Linköping University, Sweden, who have developed a type of sensor able to detect circularly polarized ...

'Brainless' robot can navigate complex obstacles

Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a "brainless" soft robot that can navigate more complex and dynamic environments. ...

The robustness of the world's skyscrapers stress-tested by model

The safety of tall buildings in the world's cities, in the face of extreme external traumas like vehicle impacts, blasts or fires, has been tested using a model developed by structural engineers at the University of Surrey—with ...

Engineers use kirigami to make ultrastrong, lightweight structures

Cellular solids are materials composed of many cells that have been packed together, such as in a honeycomb. The shape of those cells largely determines the material's mechanical properties, including its stiffness or strength. ...

We could soon be getting energy from solar power harvested in space

The idea of space-based solar power (SBSP)—using satellites to collect energy from the sun and "beam" it to collection points on Earth—has been around since at least the late 1960s. Despite its huge potential, the concept ...

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.
