Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two variables, building an array ...

Exploring mysteries on the surface 2D materials reveal surprising properties Date: February 10, 2017 Source: Ames Laboratory Summary: Scientists have discovered the unique properties of two ...

The angle of the interlayer twist stems from a mismatch between the flat 2D crystals and the curved surfaces they grow on, they explain, and two different types of spiral are possible. When a spiral ...

A research team has developed a tape that can be used to stick two-dimensional (2D) materials to many different surfaces, in an easy and user-friendly way. Their finding will aid research into and ...

Until now, no 2D piezoelectric material has been manufactured in large sheets, making it impossible to integrate into silicon chips or use in large-scale surface manufacturing, the researchers say.

Spectroscopic scans provide information about surface composition at the atomic and molecular levels. The scans are converted into images, forming topographical maps of the material’s surface. “With ...

Like a pond, these 2D surfaces have tiny ripples that affect their properties. The researchers used machine learning-based computer models that represent 2D sheets of graphene and other materials.

For example, the surface of a giant doughnut is another 2D space. Through a field called geometric topology, mathematicians like me study all possible spaces in all dimensions.
