Seamless Mechanical Programming Through Hybrid Epoxy–Acrylate Printing for Soft–Rigid Robots

open access: yesAdvanced Materials, EarlyView.
Hybrid epoxy‐acrylate printing enables seamless fabrication of soft–rigid robotic systems with covalently integrated interfaces and functionally graded mechanics. Grayscale exposure expands the accessible material space, enabling spatially programmed actuation through patterned stiffness while revealing the mechanics and durability of continuously ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites

open access: yesAdvanced Materials, EarlyView.
Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

The “hidden workers”: livestock farmers’ perceptions of ecosystem services provided by dung beetles

open access: yesEcology and Society
Non-native dung beetles were introduced to Australian agricultural systems to provide ecosystem services, such as pasture cleaning and to control dung-breeding flies, which benefit particularly livestock farmers.

Landscape attributes shape dung beetle diversity at multiple spatial scales in agricultural drylands

open access: yesBasic and Applied Ecology, 2022
Land-use change is one of the main drivers of biodiversity loss worldwide, but its negative effects can vary depending on the spatial scale analyzed.

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

open access: yesAdvanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Quantifying immediate and delayed effects of anthelmintic exposure on ecosystem functioning supported by a common dung beetle species. [PDF]

open access: yesPLoS ONE, 2017
Dung beetles (Coleoptera: Scarabaeoidea) support numerous ecosystem functions in livestock-grazed pastures. Exposure to veterinary anthelmintic residues in livestock dung can have lethal and sublethal effects on dung beetles, and can reduce rates of dung

Anatomical organization of the brain of a diurnal and a nocturnal dung beetle [PDF]

open access: yes, 2018
To avoid the fierce competition for food, South African ball‐rolling dung beetles carve a piece of dung off a dung‐pile, shape it into a ball and roll it away along a straight line path.

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

open access: yesAdvanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...
