Ionic liquids pack a punch for biofuels (Day 327)

In my blog, ‘the sweet smell of success‘, I discussed the use of ionic liquids – salt in a liquid state as a result of poor ionic co-ordination – in perfumes and alluded to other fields of research where they are used. Today I’m delving a little further and shining a light on the use of ionic liquids in biofuels.

Researchers at North Carolina State University, US, (NCSU) are investigating the use of ionic liquids to strip lignin from plant cells. Their aim is to find a cost-effective method of processing biomass for biofuel production.

Lignin is a complex phenolic polymer that is found in plant cell walls. It plays an important structural role, providing the plant with strength and rigidity due to a cross-linked structure that is difficult to break down. After cellulose, it is the most abundant source of renewable carbon on earth.

Breakthrough in 3D printing inspired by the Terminator (Day 314)

3D printing is a misnomer; it is actually 2D printing over and over again.

Most 3D printing occurs by building up objects layer-by-layer. However, Carbon3D Inc has developed a new method that allows objects to rise continuously from a liquid media.

Joseph M. DeSimone, professor of chemical engineering at NC State University, US, and of chemistry at the University of North Carolina (UNC) at Chapel Hill, US, is currently CEO of Carbon3D.

Joe co-invented this new method with colleagues Alex Ermoshkin, chief technology officer at Carbon3D and Edward T. Samulski, also professor of chemistry at UNC.

chromeJoe says that this idea was inspired by the Hollywood film, Terminator 2: Judgement Day. In this film, the T-1000 robot rises from a liquid metal puddle to assume its form. This made Joe and his team think – why can’t we create objects in this way?
