A new role for chlorine: Uncovering anion redox in solid-state battery cathodes

Science via Phys.org
Quick Read

As demand grows for safer and more capable rechargeable batteries, scientists are looking beyond the familiar metal-centered chemistry of conventional cathodes. A promising route is to draw additional charge from anions—the negatively charged atoms in a material—rather than relying on transition metals alone. Oxygen and sulfur have attracted substantial attention in this area. Whether chlorine can play a comparable role in chloride-based battery cathodes has been less clear.

Repeat thieves without kleptomania struggle to adapt to rewards in decision-making test

Theft is almost universally considered an exploitative behavior. The conventional view underlying judicial systems is that the act of taking resources from others without offering compensation stems from moral and personal failings. As a result, these systems rely on the assumption that the threat or imposition of punishment will motivate criminal offenders to adjust their future behavior. Yet the outcome is not always success.

Team designs molecules that efficiently generate orange-to-red light for OLED displays

Most of us spend much of our day staring at organic light-emitting diodes, or OLEDs, which convert electricity into light to produce the colorful displays on smartphones, computer monitors and televisions. Although metal-free light-emitting materials that produce all colors are in demand, it has been difficult to make ones that efficiently emit orange-to-red light. Now, researchers led by the University of Osaka have shown that such materials do not need to be held in a rigid shape to work well: flexible molecules that can change shape can also emit orange-to-red light.

A catalyst that protects itself while producing hydrogen

Cobalt phosphide (CoP) is a promising alternative to platinum for producing hydrogen from water. However, scientists have struggled to explain why it performs so well. Computer models have suggested that CoP should become unstable under the conditions used to produce hydrogen, yet experiments show that it remains active and durable in acidic, neutral and alkaline environments.
