Interlocking rings unlock new material properties

Researchers working with Jonathan Barnes, assistant professor in the Department of Chemistry, have recently shown how molecules with interlocking ring architectures can be functionalized and incorporated into three-dimensional ...

All wound up: A reversible molecular whirligig

Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, ...

Enhancing the electromechanical behavior of a flexible polymer

Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers—materials composed of molecular ...

Breaking down plastic into its constituent parts

A team of ETH researchers led by Athina Anastasaki have succeeded in breaking down plastic into its molecular building blocks and in recovering over 90% of them. A first step towards genuine plastic recycling. The chemical ...

Polymer that folds and unfolds under UV radiation

Polymers, the basis of all plastics, usually do not have an ordered structure, in contrast to biopolymers such as proteins. A team of researchers has now developed a polymer that can be differentiated into folded (ordered) ...

Chemists develop a fundamentally new mode of adsorption

A research team, led by Northwestern Universitychemists, has made a breakthrough in surface science by introducing a new active mechanism of adsorption. Such adsorption-based phenomena, in which molecules are attracted onto ...
