We developed ‘self-oscillating’ polymer gels that undergo spontaneous cyclic swelling–deswelling changes without any on–off switching of external stimuli like a heart muscle. Here, our ...

ResearchI work on characterizing the interactions between redox-active polymers and electrolyte. This involves looking at how the polymer microstructure changes as a function of swelling and ...

Multinetwork polymer gels with color-changing linkers sensitive to mechanical stimuli provide a solid platform to study the dynamics of solvent swelling, as shown by researchers from Tokyo Tech.

By varying the side-chain length of these brushes, they could fine-tune the melting temperatures, thus modulating swelling and wettability. The study mainly focused on P18MA and compared it to a ...

Advancements in Polymer Brush Technology. Polymer brushes are thin layers of polymer chains chemically tethered to a surface at one end, allowing them to extend into the surrounding environments.

Thin polymer discs self-propel by repeated 'snapping' motions. (Credit: Yongjin Kim, UMass Amherst) A polymer-based gel made by researchers in the US and inspired by the Venus flytrap plant can snap, ...

Development of Porous Swelling Copolymeric Bone Anchor for Orthopedic Applications. Thursday, August 15, 2024. 10:00 AM-12:00 PM. BIOMED PhD Thesis Defense ... The results of the swelling and ...

Proton conductivity in Nafion, and most other polymer electrolytes, increases with water activity, and is maximized when equilibrated with liquid water (water activity a w =1). Operation at a w =1 ...

The hydrogel swells faster than it shrinks, while its rate of swelling slows even as the electrical current remains constant. The researchers say that these properties create a rudimentary sort of ...

Demonstrating that making sustainable plastics isn’t necessarily a sustainable business, two prominent green plastics operations—the biobased polymer maker Danimer Scientific and Brightmark ...
