New indicator for oxygen levels in early oceans developed

Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth. It was not until the evolution of photosynthetic bacteria that the oceans saw a significant increase ...

Unusual electron sharing found in cool crystal

A team of scientists led by Nagoya University in Japan has detected a highly unusual atomic configuration in a tungsten-based material. Until now, the atomic configuration had only been seen in trihydrogen, an ion that exists ...

Scientists develop tungsten-based hydrogen detectors

A team of physicists from Immanuel Kant Baltic Federal University together with their colleagues from National Research Nuclear University MEPhI (NRNU MEPhI) has developed a tungsten oxide-based detector of hydrogen in gas ...

An unlikely marriage among oxides

The term alloy usually refers to a mixture of several metals. However, other materials can also be alloyed. In the semiconductor industry, for instance, oxide and nitride alloys have long been used successfully to tune the ...
