Scientists discover new forms of feldspars

In high-pressure experiments, scientists have discovered new forms of the common mineral feldspar. At moderate temperatures, these hitherto unknown variants are stable at pressures of Earth's upper mantle, where common feldspar ...

Earth's lower mantle can be oxidized in the presence of water

If we took a journey from Earth's surface to the center, the midway point is roughly at 1900 km depth in the lower mantle. The lower mantle ranges from 660 to 2900 km depth and occupies 55% of our planet by volume. The chemical ...

Platinum-free catalysts could make cheaper hydrogen fuel cells

The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency ...

'Water wires' may play bigger role in cellular function

Each of our cells is surrounded by a complex membrane that functions as a biological border, letting ions and nutrients such as salt, potassium and sugar in and out. The guards are membrane proteins, which do the hard work ...

Study reveals single-step strategy for recycling used nuclear fuel

A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused ...

Red light for stress: A color-changing organic crystal

Researchers at the Institute of Industrial Science, part of The University of Tokyo, and Yokohama City University have introduced novel color-changing organic crystals that spontaneously return to their original shape and ...

Upgrading biomass with selective surface-modified catalysts

Scientists have designed a catalyst composed of very low concentrations of platinum (single atoms and clusters smaller than billionths of a meter) on the surface of titanium dioxide. They demonstrated how this catalyst significantly ...
