Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

Interdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.

Twisted rods, helices and buckling solutions in three dimensions

, 2013
The study of slender elastic structures is an archetypical problem in continuum mechanics, dynamical systems and bifurcation theory, with a rich history dating back to Euler's seminal work in the 18th century. These filamentary elastic structures have widespread applications in engineering and biology, examples of which include cables, textile industry,
