Journal ArticleDOI
Origami-like unfolding of hydro-actuated ice plant seed capsules
Matthew J. Harrington,Khashayar Razghandi,Friedrich Ditsch,Luigi Guiducci,Markus Rueggeberg,John W. C. Dunlop,Peter Fratzl,Christoph Neinhuis,Ingo Burgert +8 more
TL;DR: This work investigates the structural and compositional basis of a sophisticated plant movement mechanism--the hydration-dependent unfolding of ice plant seed capsules--the reversible origami-like folding pattern proceeds via a cooperative flexing-and-packing mechanism actuated by a swellable cellulose layer filling specialized plant cells.
Journal ArticleDOI
Nanofibers from blends of polyvinyl alcohol and polyhydroxy butyrate as potential scaffold material for tissue engineering of skin.
TL;DR: Cell culture experiments with a human keratinocyte cell line (HaCaT) and dermal fibroblast on the electrospun PHB and PVA/PHB blend nanofibers showed maximum adhesion and proliferation on pure PHB, however, the addition of 5 wt % PVA to PHB inhibited growth of HaCaT cells but not of fibroblasts.
Journal ArticleDOI
Honeycomb Actuators Inspired by the Unfolding of Ice Plant Seed Capsules.
Luigi Guiducci,Khashayar Razghandi,Luca Bertinetti,Sébastien Turcaud,Markus Rüggeberg,James C. Weaver,Peter Fratzl,Ingo Burgert,Ingo Burgert,John W. C. Dunlop +9 more
TL;DR: This work extracts the design principles behind the unfolding of the ice plant seed capsules, and uses two different approaches to develop autonomously deforming honeycomb devices as a proof of concept.
Journal ArticleDOI
Hydro-actuation of ice plant seed capsules powered by water uptake
Khashayar Razghandi,Luca Bertinetti,Luigi Guiducci,John W. C. Dunlop,Peter Fratzl,Christoph Neinhuis,Ingo Burgert +6 more
TL;DR: In this article, the authors found that the initial enthalpy-driven adsorption of water can only account for increasing the moisture content up to about 0·4 µmg/mg, which is not sufficient to initiate the actuation.
Journal ArticleDOI
Rethinking filter : An interdisciplinary inquiry into typology and concept of filter, towards an active filter model
TL;DR: The research approach is put forward as a paradigm for how seemingly disciplinary concepts such as Filter can be rethought through interdisciplinary methods, and mutually complement research questions within active matter, biology, information philosophy, data science and sustainability discourses.
