Researchers have confirmed the original model of the molecular structure of water and have thus made it possible to resolve a long-standing scientific controversy about the structure of liquid water.

Tetrahedral kites make for a great DIY project. Originally developed by Alexander Graham Bell, these simple kites can be built out of straws, fishing line and paper. The weight to sail area coupled ...

Voltage fade has long haunted high-energy lithium-ion batteries, quietly eroding performance long before capacity ...

Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed. Physicists ...

The tetrahedral geometry of four-coordinate carbon atoms is a steadfast property of organic compounds. Nevertheless, chemists are still attracted to the possibility of twisting or squashing a ...

Water holds a special place among liquids for its unusual properties, and remains poorly understood. For example, it expands just upon the freezing to ice, and becomes less viscous under compression, ...

Lithium-rich layered oxides (LRLOs) offer exceptionally high capacities but suffer rapid energy loss because of irreversible migration of ...

[Dan Hemingson’s] been refining a design for building a tetrahedral ambisonic recording system. This is a set of four microphones used to record audio that can later be mixed down for a ...

occupying the octahedral holes. Notice that the octahedral holes are along the edges (for a net of three cations) and in the center of the cube (one more cation). Thus we have four anions (FCC) and ...
