Birds among us: Perceptions of bird‐mediated services and disservices in a northern city

open access: yesPeople and Nature, EarlyView.
Abstract Birds can benefit people or cause harm. Understanding how people perceive birds in cities, where most daily interactions among people and nature occur, could inform decision‐making in support of biodiversity and human well‐being We distributed a survey in a growing mid‐sized city (Lahti, Finland) to evaluate which bird‐mediated ecosystem ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

The Long Trajectory of Rubber Physics: 3500+ Years and Counting

open access: yesJournal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...

An Enhanced Soft‐Containing Gripper for Pick‐And‐Place of Oyster Products at Extreme Handling Speed

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Soft robotic grippers have been developed for high‐speed handling of soft, fragile foods. For example, our previously designed soft‐containing gripper has been implemented on food production lines. However, existing soft robotic grippers remain inadequate for food pick‐and‐place tasks at extreme handling speeds (e.g., > 70 pcs/min).

Template‐free tuning of magnetic nanoparticle self‐assemblies in response to external electric and magnetic fields

open access: yesResponsive Materials, EarlyView.
Electrostatically charged aerosol magnetic nanoparticles enable template‐free self‐assembly of nanochains with tunable length and spacing by adjusting electric‐to‐magnetic field ratios. Lower electric fields favor the self‐assembly of longer and more spatially separated chains, while higher electric fields promote a uniform nanoparticle deposition and ...
