Impurities enhance polymer LED efficiencies

Molecular dynamics simulations have shown that the mysteriously high efficiency of polymer LEDs arises from interactions between triplet excitons in their polymer chains, and unpaired electrons in their molecular impurities.

Polyimide membranes for the purification of natural gas

Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be 'sweetened' by removal of its acidic impurities. Through fine tuning ...

Protein discovered inside a meteorite

A team of researchers from Plex Corporation, Bruker Scientific LLC and Harvard University has found evidence of a protein inside of a meteorite. They have written a paper describing their findings and have uploaded it to ...

A thermometer that can be stretched and deformed by water

Recent outbreaks of the novel coronavirus have emphasized the importance of quarantine and prevention more than ever. When monitoring changes in our body, body temperature is measured first, so it is very important to measure ...

Self-assembled artificial microtubule like LEGO building blocks

Simple LEGO bricks can be assembled to more complicated structures, which can be further associated into a wide variety of complex architectures, from automobiles, rockets, and ships to gigantic castles and amusement parks. ...

Widening metal tolerance for hydrogels

Researchers seeking to develop self-healing hydrogels have long sought to mimic the natural ability of mussels to generate strong, flexible threads underwater that allow the mussels to stick to rocks.
