How core-mantle differentiation influenced the distribution of volatile elements on Earth. Imagine Earth's history as a ...

Most people can't answer this science trivia ... can you? How well do you know science trivia? Even if it’s been years since ...

Imagine if Earth's history had a mystery novel, and one of its biggest unsolved puzzles was: Where did all the nitrogen go?

This hierarchy—nitrogen > carbon > argon in core preference—may solve two mysteries. To quantify this, the researchers built a model of Earth’s accretion 4.6 billion years ago. Suppose Earth ...

The problem is that the half-reaction that produces oxygen, known as the oxygen evolution reaction (OER), is difficult and inefficient and takes more energy than predicted by theory. “It should ...

To deal with this drawback, we propose a two-dimensional multiple frequency atomic norm minimization algorithm (2DMFANM) to estimate the elevation and azimuth angles of wide-band signals in a gridless ...

Of those six compositions, only the mixture of nitrogen and argon proved suitable, modifying the material in a way that doubled its areal capacitance. While this is in no way a record for such ...

The model also accounts for effects of soil nitrogen and atmospheric CO 2 concentration on gaseous exchange of water and carbon by the leaf. With different nitrogen and water input values, TGFS ...
