The MIT Libraries is completing a major upgrade to DSpace@MIT. Starting May 5 2026, DSpace will remain functional, viewable, searchable, and downloadable, however, you will not be able to edit existing collections or add new material. We are aiming to have full functionality restored by May 18, 2026 but intermittent service interruptions may occur. Please email dspace-lib@mit.edu
with any questions. Thank you for your patience as we implement this important upgrade.

| dc.description.abstract | Tungsten (W) nanowires have a wide range of chemical, electronic, and mechanical applications. However, the modulus and strength of traditional W nanowires are quite low, and how to improve their mechanical performance remains a challenge. Here, we describe a novel graphene-coated W nanowires that demonstrate a Young’s modulus of 885 GPa (twice that of W) and a fracture strength of up to 24.7 GPa (66% of the ideal strength). Both the Young’s modulus and the fracture strength show a strong size effect, resulting from the graphene-nanowire core–shell structure. Keywords: W nanowires; graphene; Young's modulus; fracture strength; size effect | en_US |
