Part II: Advanced Rheometric Applications for Aging/Mutating Systems

Webinar Part II: Advanced Rheometric Applications for Aging/Mutating Systems In this second part of the webinar series on rheometric applications, we explore advanced applications of Optimally Windowed Chirps (or OWCh) to characterize complex material systems, including aging thixotropic systems such as clay dispersions. We describe how user control of the initial phase and the frequency…

Novel 3D Printed Liquid Crystal Elastomers and the Characterization of their Anisotropy, Rate-Dependency, and Dissipation Properties

Overview Liquid-crystal elastomers (LCEs) uniquely combine molecular ordering with entropic elasticity. The result is a class of anisotropic elastomers with remarkable properties spanning stimuli responsive actuation to exceptional dissipation of mechanical energy. Our group has recently developed a range of photopolymerizable LCE resins and inks which we 3D print using direct ink writing (DIW) and…
