Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

Advanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Physiological basis of resistance of rice plants for submersion under water

Japanese Journal of Crop Science, 1955
When rice plants are submerged under water in the case of flooding, the oxygen content in the internal atmosphere of rice plants is remarkably decreased due to the insufficient supply of oxygen to the plants. Under reduced oxygen tension, aerobic respiration is reduced and at the same time anaerobic respiration is promoted, both resulting in the ...

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives

Advanced Functional Materials, EarlyView.
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes
