Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

Implications for the rail freight sector of stricter European Union locomotive emission limits: a UK perspective [PDF]

open access: yes, 2016
The European rail freight sector has grown exponentially over the past twenty to thirty years as the limitations of road transport have become increasingly apparent.† Moreover, moving more freight by rail is seen as a greener alternative.†† Thus, in some
