Studies on a-Cyanoacrylate. IV

Journal of Synthetic Organic Chemistry, Japan, 1966
In view of the fact that alkyl α-cyanoacrylates are usually prepared by thermal degradation of the corresponding polymers, the degradation of polycyanoacrylates under nitrogen at 230-160°C was investigated by means of a heat balance. The degradation velocity of the polymer decreased in the following order: when anionic polymerization products were used,

Dual‐Biomimetic Bone Adhesive with Osteoimmunomodulatory Capabilities for Anatomical Reconstruction of Comminuted Fractures

Advanced Science, EarlyView.
A structurally and functionally dual bionic bone adhesive is engineered through an organic–inorganic cohesion strategy, which significantly reinforces the adhesive's bone tissue adhesion as well as osteogenic activity. In a pioneering rabbit radius comminuted fracture model, the bone adhesive exhibits exceptional capability in immobilizing bone ...

Microstructural Origin of Nonmonotonic Piezoresistivity in Polymer Nanocomposites

Advanced Science, EarlyView.
When polymer nanocomposites are subjected to tensile loading, the electrical resistance‐strain relationship may be nonmonotonic, hampering the use of these materials in real‐world applications. This challenge is addressed through the collaborative use of physical experimentation and computer simulations, establishing the inter‐nanotube junction ...
