We study the non-Fourier heat conductions in nanomaterials based on thermomass theory. For transient conduction a one-dimensional nanomaterial with low-temperature step at both ends, temperature response predicted by present model is consistent those existing theoretical models for small steps. However, if large, unphysical distribution under zero other models, when two cooling waves meet, does not appear predictions model. The steady-state equation derived has been applied to predict...
In this study, for the first time, we fabricated flexible, high-heat-resistant, and amphiphobic mats by (fluoroalkyl)silane (FAS) modification of electrospun pure silica nanofibrous mats.

PVA/silica fibers found be randomly oriented as nonwoven with fiber diameters in range 150−500 nm. After FAS modification, surface wettability was converted from...
