Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

open access: yesAdvanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Recovery of the Dye Intermediate DNDS from Aqueous Solution by Adsorption onto Resins

open access: yesAdsorption Science & Technology, 2006
Four kinds of resins were investigated for the recovery of 4,4‘-dinitrostilbene-2,2’-disulphonic acid (DNDS), which is present as a pollutant in wastewater, and their adsorption behaviour and mechanisms assessed. One of the resins, YWB-38, exhibited much

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

open access: yesAdvanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...
