These are novel molecules for OLEDs that can store electrical energy for significantly longer than is conventionally assumed. Credit: Image: Prof. Dr. John Lupton/Uni Regensburg Researchers from the universities of Bonn and Regensburg have developed a novel type of organic light-emitting diode (OLED). These lights are suitable for the design of particularly energy-efficient cheap displays,

Excited-state intramolecular proton transfer (ESIPT) makes possible organic light-emitting diodes (OLEDs) that are highly efficient by creating the necessary conditions to enable thermally activated delayed fluorescence (TADF). After excitation of the emitting molecule, a hydrogen atom — technically, just its nucleus — is transferred to a different atom in the same molecule through a process

Rice University scientists have fabricated a durable catalyst for high-performance fuel cells by attaching single ruthenium atoms to graphene.

Catalysts that drive the oxygen reduction reaction that lets fuel cells turn chemical

Image of Enceladus with the location of a possible confined methanol cloud, the methanol spectrum from the study and images of the methanol molecule. A serendipitous detection of the organic molecule methanol around an intriguing moon of Saturn suggests that material spewed from Enceladus undertakes a complex chemical journey once vented into space. This is

Researchers at Berkeley Lab and MSU have obtained the first atomic-level view of an intact bacterial microcompartment, shown here. Credit: Markus Sutter/Berkeley Lab and MSU Scientists are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle’s protein shell. The work, led by scientists

This confocal microscopic image shows a human colon organoid generated in the laboratory with human pluripotent stem cells. The organoid is shown after it was transplanted into a mouse. The engineered colon secreted proteins found in natural human colon. Credit: Cincinnati Children’s Scientists used human pluripotent stem cells to generate human embryonic colons in a

A “film” drop (red) and “jet” drop (blue) from bursting bubble filmed 8 milliseconds apart.

This is a graphic showing how sugar and carbon dioxide is converted to plastic. Credit: Georgina Gregory Some biodegradable plastics could in the future be made using sugar and carbon dioxide, replacing unsustainable plastics made from crude oil, following research by scientists from the Centre for Sustainable Chemical Technologies (CSCT) at the University of Bath.

The results of tests conducted by UConn chemists show that nicotine electronic cigarettes are equivalent, if not slightly worse, than unfiltered (nf) tobacco cigarettes when it comes to causing DNA damage. Non-nicotine (nn) e-cigarettes cause damage similar to filtered tobacco cigarettes. The amount of relative DNA damage is reflected by the intensity of the color
