Nonlinear Dynamics of the High-Speed Rotating Plate
International Journal of Aerospace Engineering, 2018 High speed rotating blades are crucial components of modern large aircraft engines. The rotating blades under working condition frequently suffer from the aerodynamic, elastic and inertia loads, which may lead to large amplitude nonlinear oscillations ...

Laser‐Induced Local De‐Doping in Organic Semiconductors
Advanced Materials Technologies, EarlyView.The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface
Advanced Materials Technologies, EarlyView.Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Spectral Splitting Using Luminescent Solar Concentrator Lightguides
Advanced Optical Materials, EarlyView.Attaching selective reflectors to the edges of a luminescent solar concentrator containing two different fluorescent dyes makes it possible to parse the incident white light spectrum into two separate edge emission wavelengths. Separation may be enhanced by aligning the dichroic dyes on the lightguide surface.
