Scientists now able to map defects in 2D crystals in liquid

Published:19.04.21 — A team of EPFL scientists has studied the behavior of defects on 2D crystals in water in order to better understand the crystals’ properties and assess their quality.

Rivers and streams emit much more CO2 at night than during the day

Published:16.04.21 — EPFL scientists have found that streams and rivers – or “running waters” – emit on average 27% more CO2 at night than during the day. That matters because most estimates of global CO2 emissions are made using measurements taken during the day, thereby introducing a potential bias into the calculation of the global carbon cycle.

Water and quantum magnets share critical physics

Published:16.04.21 — Water can freeze from liquid to solid ice or boil into a gas. In the kitchen these “phase transitions” aren’t smooth, but their discontinuous nature is smoothed out at high pressure. An international team of physicists led by EPFL has now discovered the same behavior in certain quantum magnets, which may have consequences for the technology of qubits.

Uncovering the secrets of some of the world's first color photographs

Published:15.04.21 — EPFL researchers have shed new light on one of the earliest color photography techniques, G. Lippmann’s Nobel Prize–winning multispectral imaging method.

New hydrogel can repair tears in human tissue

Published:14.04.21 — EPFL scientists have developed an injectable gel that can attach to various kinds of soft internal tissues and repair tears resulting from an accident or trauma.
