Shape Memory Soft Robotics with Yield Stress Fluids

open access: yesAdvanced Intelligent Systems, Volume 5, Issue 8, August 2023., 2023
Many organisms use non‐Newtonian fluids and pressurized cavities to produce movement. Inspired by these biological motifs, this study 3D prints soft robotics into a yield stress support matrix and retains the support material as the power transmission fluid.

Association between shell morphology of micro-land snails (genus Plectostoma) and their predator’s predatory behaviour [PDF]

open access: yes, 2014
Predator–prey interactions are among the main ecological interactions that shape the diversity of biological form. In many cases, the evolution of the mollusc shell form is presumably driven by predation.

Ingestion and toxicity of microplastics in the freshwater gastropod Lymnaea stagnalis: No microplastic-induced effects alone or in combination with copper.

open access: yesChemosphere, 2021
The interaction of microplastics with freshwater biota and their interaction with other stressors is still not very well understood. Therefore, we investigated the ingestion, excretion and toxicity of microplastics in the freshwater gastropod Lymnaea ...
