Chemical signatures of iron predict red supergiant temperature

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers have ...

Vibrating 2-D materials

Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure ...

Improving high-energy lithium-ion batteries with carbon filler

Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible ...

Oligomeric materials to enhance water splitting

Researchers from the Llobet group have developed a new molecular material made out of oligomers and used it as a catalyst in water oxidation, achieving unprecedented current densities for molecular catalysts. The paper "Water ...
