have changed the scope of network computing. As the Internet user population has grown, so has the demand for better ways to collaborate on the Internet. Some examples include the ability to share and discuss issues of common interest, coauthor documents, and track project status. Although today's WWW is ideal for publishing information, it requires(More)
Highly resilient synthetic hydrogels were synthesized by using the efficient thiol-norbornene chemistry to cross-link hydrophilic poly(ethylene glycol) (PEG) and hydrophobic polydimethylsiloxane (PDMS) polymer chains. The swelling and mechanical properties of the hydrogels were controlled by the relative amounts of PEG and PDMS. The fracture toughness(More)
Polymer networks are critically important for numerous applications including soft biomaterials, adhesives, coatings, elastomers, and gel-based materials for energy storage. One long-standing challenge these materials present lies in understanding the role of network defects, such as dangling ends and loops, developed during cross-linking. These defects can(More)
