Magnetic nanoparticles with ionic liquids for water purification

Providing Safe, Clean Water

03-Dec-2019

In many parts of the world, access to clean drinking water is far from certain. Filtration of large volumes of water, however, is slow and impractical. In the journal Angewandte Chemie, scientists have introduced a new water purification method based on magnetic nanoparticles coated with a ...

'Dancing' holes in droplets submerged in water-ethanol mixtures

03-Jul-2018

Researchers from Tokyo Metropolitan University have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This curious, complex phenomenon is driven by an interplay between how ionic liquids dissolve, and how the boundary ...

Photoreversible molecular switch changes the physical property of thermoresponsive polymer

05-Feb-2018

Researchers have developed a novel strategy to control the shapes of polymeric materials by utilizing photoresponsive molecular switches, which may evolve tractable stimuli-responsive soft materials. Ionic liquids (ILs) are liquid-state salts at room temperature and are high-potential materials ...

A gel that does not break or dry out

13-Nov-2017

Researchers have developed a highly robust gel that includes large amounts of ionic liquid. The research team was led by Professor Matsuyama Hideto and Assistant Professor Kamio Eiji (Kobe University Graduate School of Science, Center for Membrane and Film Technology). Ionic liquid is a substance ...

Ionic liquids simplify laser experiments on liquid samples

20-Oct-2016

An HZB team has developed a new approach to conduct photoemission spectroscopy of molecules in solution. This has been difficult up to now because the sample needed to be situated in vacuum – but liquids evaporate. The work has now demonstrated it is feasible to replace the solvent with an ionic ...

Using nature's own solvents for the preparation of pure lignin

16-Sep-2016

Lignin can now be efficiently and cost-effectively separated from sawdust, by using eutectic solvents. VTT Technical Research Centre of Finland has developed solvents using which 50% of the lignin from wood can be extracted in a pure form that retains its natural chemical structure during ...

At attention, molecules!

19-May-2016

When you touch your phone's screen, you might not realize that you've set off a molecular chain reaction. Your fingertip sends a jolt of electricity (albeit tiny) that disturbs rows of molecules meticulously assembled at the screen's surface and dictates the action, whether it's opening a new ...
