Traditional knowledge promotes the protection of large old trees: A case from China's richest biocultural diversity area

open access: yesPeople and Nature, EarlyView.
Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

open access: yesPolymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Actuation and Charging Mechanisms of Thin PEDOT:PSS Films Probed by Electrochemical AFM and Impedance Spectroscopy

open access: yesJournal of Polymer Science, EarlyView.
The actuation of thin films of PEDOT:PSS has been characterized by electrochemical AFM. A relative decrease in the actuation behavior in dependence of the film thickness has been observed. The underlying mechanisms have been elucidated by chronoamperometry and electrochemical impedance spectroscopy. The decreasing relative actuation is attributed to an
