Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

open access: yesAdvanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]

open access: yes, 2009
Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'

Branching of nursery apples and plums using various branching inducing methods [PDF]

open access: yesJournal of Central European Agriculture, 2020
Chemical (benzyladenine - BA, gibberelins - GA4/7), mechanical (leaf pinching), and combined treatments were tested in 2015 and 2016 to increase the number and length of sylleptic side shoots (feathers) on apple (´Rubinola´, ´Topaz´/M9) and plum (´Elena´,

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

open access: yesAdvanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...

Unzipping bird feathers [PDF]

open access: yesJournal of The Royal Society Interface, 2014
The bird feather vane can be separated into two parts by pulling the barbs apart. The original state can be re-established easily by lightly stroking through the feather. Hooklets responsible for holding vane barbs together are not damaged by multiple zipping and unzipping cycles.
