The transmission spectrum of single-molecule junctions provides fingerprint information on the charge-transport properties. A technique called single-molecule photoelectron tunnelling spectroscopy has ...

This illustration depicts a white dwarf star merging with a red giant star. A bow shock forms as the dwarf plunges through the star’s outer atmosphere. The passage strips down the white dwarf’s outer ...

The term ‘Bio/blood compatibility’ is generally used to indicate the properties of polymeric materials that do not cause adverse effects when in contact with components of living organisms, such as ...

In a recent study published in Nature Astronomy, astronomers using NASA’s Hubble Space Telescope have uncovered an extraordinary white dwarf star, named WD 0525+526. Unlike typical white dwarfs, which ...

A distant white dwarf star has been observed consuming a frozen, Pluto-like world rich in ice and volatile materials. Astronomers have detected nitrogen, oxygen, sulphur and carbon in the remnants.
