Woolf’s Weighty Gifts: The Measure of Modernist Autonomy

open access: yesNANO, 2017
This paper argues that Virginia Woolf’s A Room of One’s Own (1929) provides a critical counterpoint to a cluster of recent discourses on the gift, autonomy, and the changing nature of labor in the contemporary creative economy.

Designing Strong, Tough, Fire‐Retardant and Self‐Healing Elastomers with Phosphorus/Nitrogen‐ and Biphenyl‐Containing Segments

open access: yesAdvanced Materials, EarlyView.
By designing a P/N‐ and π–π interacting biphenyl‐containing diol as hard segments but side groups, a strong, tough, fire‐extinguishing and self‐healing elastomer is developed, demonstrating a break strain of ∼2500%, a toughness of 379 MJ/m3 and a tensile strength of 46 MPa, as well as a healing efficiency of 95% (tensile strength) and 99% (break strain)
