Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams
Advanced Functional Materials, EarlyView.A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Genetically Programmed Shape‐Morphing of Engineered Living Materials
Advanced Functional Materials, EarlyView.Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Effects of bromination on the viscoelastic response of vinyl ester nanocomposites
eXPRESS Polymer Letters, 2009 Fire, smoke and toxicity are of significant concern for composite materials used in marine applications. Bromination of vinyl ester resin imparts fire retardancy as manifested by a reduction in the amount of smoke, carbon monoxide, and corrosive ...

Viscoelastic behaviour of basaltic lavas. [PDF]
, 2004 The rheological properties of basaltic lavas from Etna, Hawai′i and Vesuvius have been investigated at temperatures between 500 and 1150°C using a small-strain oscillatory shear. The viscoelastic response of the lavas to small, forced, sinusoidal torques

Compressive mechanical properties of HTPB propellant at low temperatures and high strain rates
Results in Physics, 2017 To study the compressive mechanical properties of the hydroxyl-terminated polybutadiene (HTPB) propellant at high strain rates (700–1900/s) and low temperatures (−50 °C to 25 °C), we conducted a dynamic mechanical experiment using cylindrical specimens ...
