Computer program pins down carbon capturing ionic liquids

Scientists have developed a computer-aided method that designs carbon capturing ionic liquids and at the same time finds their optimal operating conditions.

Capturing and storing carbon dioxide decreases its global warming potential. Ionic liquids, salts that are liquid at room temperature, can trap large amounts of carbon dioxide. However, there are thousands of ionic liquids – their properties are dictated by their comprising anions and cations, and their ability to dissolve CO2 depends on temperature and pressure.

Crawling chemical system acts as if it’s alive

They crawl. They eat. They excrete. So you’d be forgiven for thinking these globules created by a team Japan were alive – but they’re not.

Discovering life-like motion in non-living systems fascinates Akihisa Shioi, from Doshisha University. He and his team are constantly combining new chemicals to investigate the idea.

They already knew that droplets of didodecyldimethylammonium bromide (DDAB), a cheap surfactant, react with iodide ions, then scoot around and leave chemical traces, like miniature turbo-snails. Unlike snails though, these vesicles shrank, and collapsed after a few seconds. They needed feeding. Oleic acid and calcium ions proved the missing link.
