Materials made of self-spinning particles

Matter is either gas, liquid or solid based on how its molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found ...

Scientists study the types of carbon nanotube 'stuffing'

Marianna Kharlamova of the Lomonosov Moscow State University Department of Materials Science examined different types of carbon nanotube "stuffing" and classified them according to the influence on the properties of the nanotubes. ...

The computational hunt for weird and unusual tech materials

Scientists at U.S. Department of Energy's Ames Laboratory are turning to the world of computation to guide their search for the next new material. Their program uses software code developed to map and predict the distinct ...

Scientists take nanoparticle snapshots

Just as a photographer needs a camera with a split-second shutter speed to capture rapid motion, scientists looking at the behavior of tiny materials need special instruments with the capacity to see changes that happen in ...

The formation of carbon-rich molecules in space

The space between stars is not empty, but contains an abundance of diffuse material, about 5-10% of the total mass of our galaxy (excluding dark matter). Most of the material is gas, predominantly hydrogen, but with a small ...

Water was plentiful in the early universe

Astronomers have long held that water—two hydrogen atoms and an oxygen atom—was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and ...

Water could have been abundant in the first billion years

How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. Then that oxygen had to disperse and unite with hydrogen in significant ...

Improving the theory of phase transitions with supercomputers

When water molecules evaporate from a liquid phase into a gaseous phase, they alter their aggregate state. The mathematical description of such a phase transition harbours pitfalls as nucleation is needed for the change to ...
