Earth and Mars were formed from material that largely originated in the inner solar system; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of researchers led by the University of Münster (Germany) report these findings today in the journal Science Advances...

Material created with high heat yields record power output density. With energy conservation expected to play a growing role in managing global demand, materials and methods that make better use of existing sources of energy have become increasingly important. Researchers reported this week they have demonstrated a step forward in converting waste heat – from industrial smokestacks, power generating plants or even automobile tailpipes – into electricity.

The work, using a thermoelectric compound composed of niobium, titanium, iron and antimony, succeeded in raising the material’s power output density dramatically by using a very hot pressing temperature – up to 1373 Kelvin ...

The French “Microscope” orbiter will try to poke a hole in one of Einstein’s most famous theories, which provides the basis for our modern understanding of gravity. Scientists will use the kit to measure how 2 different pieces of metal—one titanium and the other a platinum-rhodium alloy—behave in orbit.

“In space, it is possible to study the relative motion of two bodies in almost perfect and permanent free fall aboard an orbiting satellite, shielded from perturbations encountered on Earth,” said Arianespace, which put the satellite into orbit on Monday.
Einstein’s theory suggests that in pe...

Researchers are testing an array of new combinations that may vastly expand the options available to create faster, smaller, more efficient energy storage, advanced electronics and wear-resistant materials.

They created 2 entirely new, layered 2D materials using molybdenum, titanium and carbon. “By ‘sandwiching’ one or two atomic layers of a transition metal like titanium, between monoatomic layers of another metal, such as molybdenum, with carbon atoms holding them together, we discovered that a stable material can be produced,” Anasori said. “It was impossible to produce a 2D material having just 3 or 4 molybdenum layers in such structures, but because we added the extra layer of titanium as a connector, we were able to synthesize them.”

It represents a new way of combining element...
