-
PhysicsElectron Superhighway
The remarkable strength and electrical properties of graphene, a chicken-wire network of carbon atoms, make it a promising new material for computer chips.
-
PhysicsAlliance of Opposites: Electrons and positrons make new molecule
Positronium, consisting of electrons and their antimatter counterparts, has been made into a molecular form.
-
PhysicsCrueltyfree: Counting photons without killing them
A delicate quantum measurement counts photons without destroying them.
-
PhysicsFrizzed molecular carpets
Measurements of the speed with which heat travels along single hydrocarbon molecules could aid in the design of molecular electronics.
-
PhysicsRoad Bumps: Why dirt roads develop a washboard surface
Experiments and a computer simulation show why dirt roads develop a washboard surface, and indicate the only way to prevent it: Drive very slowly.
-
Materials ScienceShocking Sheets: Power paper packs a punch
Ultrathin sheets made from cellulose and carbon nanotubes could serve as flexible, versatile batteries.
-
PhysicsNewton’s Dusty Mirror: Old experiment inspires ultrafast imaging
An experiment devised by Isaac Newton inspires a modern successor, in which X rays capture the image of a microscopic explosion.
-
Materials SciencePliable carbon
The layers of carbon atoms that form graphite can be assembled into strong but flexible "graphene paper."

PhysicsSlick serpent
Oil poured into a pan of the same liquid drags along a surrounding air layer, which can make it skip in and out of the surface before it mixes in.

Materials ScienceSop Story: New porous gel soaks up heavy metal
A new porous gel efficiently removes mercury from contaminated water and may also have the ability to catalyze chemical reactions such as those that generate hydrogen for fuel.
