Carbon fiber reinforced carbon aerogel composites for thermal insulation prepared by soft reinforcement

Novel antimony doped tin oxide/carbon aerogel as efficient electrocatalytic filtration membrane

“…17,18 The as-received 2 × 2-cm 2 CA specimen was pretreated in 65 wt% HNO 3 solution for 180 min, and then cleaned with deionized water and dried for 100 min at 80…”

“…This was probably due to the absence of appropriate pore structure and mechanical strength of CA. Recently, Feng 17,18 reported a flat CA with considerable mechanical strength and strong adsorption capacity, which was an ideal substrate material to prepare electrochemical membrane. On the other hand, antimony doped tin oxide (Sb-SnO 2 ) was commonly used as electrochemical catalyst, 19,20 and Sb-SnO 2 could enhance the electrode durability and oxygen evolution potential (OEP) which were conducive to degrade organics thoroughly.…”

Modelling the formation of porous organic gels – how structural properties depend on growth conditions

“…39 If one considers a random walker on a two-dimensional lattice; a particle exhibiting Brownian motion on an empty lattice, with no obstacles, has a Hurst exponent value of H ¼ 1 2 . A random walker with a lower value H < 1 2 is described as antipersistent, which means that it is more likely to remain closer to the origin than the freely diffusing particle. A value of H > 1 2 is attributed to persistent walkers, meaning they are more likely to leave the origin with a smoother, less rugged trace.…”

“…A random walker with a lower value H < 1 2 is described as antipersistent, which means that it is more likely to remain closer to the origin than the freely diffusing particle. A value of H > 1 2 is attributed to persistent walkers, meaning they are more likely to leave the origin with a smoother, less rugged trace. If one now considers a random walker on a plane with obstacles, its trace will become more antipersistent, tending to conne it to a smaller area.…”

Multi-layer graded doping in silica aerogel insulation with temperature gradient

“…Zhang et al [20] investigated the high temperature characteristics of fibrous insulating materials numerically and experimentally. Feng et al [21] experimentally studied the carbon fiber reinforced carbon aerogel. Results indicated that the doped fibers can overcome the brittleness and the pyrolysis shrinkage of carbon aerogel, thus expand the application ranges of carbon aerogel greatly.…”
