H-NbO₂—a novel van der Waals oxide synthesized by researchers from Japan—exhibits strongly correlated electronic properties ...

Two-dimensional (2D) shapes are completely flat. They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they ...

2D shapes are flat, plane shapes. Triangles have three sides and three angles that add up to 180°. Quadrilaterals have four sides and four angles that add up to 360°. Constructing triangles Learn how ...

In a surprising turn of events, an international team of scientists has found that lead-208 (208 Pb), the heaviest known "doubly magic" nucleus, exhibits unexpected shape characteristics that current ...

Princeton engineers are twisting, stretching and creasing structures to create a new type of origami, one that changes its ...

Scientists have observed that when the shape of a thin film of metal oxide known as titania is confined at the mesoscale, its conductivity increases. This finding demonstrates that nanoscale ...

Handaxes represent one of the most temporally enduring and geographically widespread of Palaeolithic artifacts and thus comprised a key technological strategy of many hominin populations.
