Carbon fiber-reinforced carbon aerogel composites (C/CAs) for thermal insulators were prepared by copyrolysis of resorcinol-formaldehyde (RF) aerogels reinforced oxidized polyacrylonitrile (PAN) fiber felts. The RF obtained impregnating PAN felts with sols, then aging, ethanol exchanging, and drying at ambient pressure. Upon carbonization, the fibers shrink aerogels, thus reducing difference shrinkage rates between reinforcements matrices, resulting in C/CAs without any obvious cracks. three...
Silica aerogels with different particle size were prepared by monodispersed silica sol for the first time. The properties of under normal and high temperature systematically studied. Among four aerogels, SA-2 sample consisted 20.31 ± 1.21 nm particles narrow distribution had resistance low thermal conductivity. Compared traditional acid-base two-step monodisperse can significantly increase while maintaining a conductivity (0.02723 W·m−1·K−1). sturdy skeleton structure formed interconnection...
Ceramic aerogels have great potential in the areas of thermal insulation, catalysis, filtration, environmental remediation, energy storage, etc. However, conventional shaping and post-processing ceramic are plagued by their brittleness due to inefficient neck connection oxide nanoparticles. Here a versatile thermal-solidifying direct-ink-writing has been proposed for fabricating heat-resistant aerogels. The versatility lies good compatibility designability inks, which makes it possible print...
The preparation of novel polymer aerogel materials with enhanced flame-retardancy, superior thermal insulation and mechanical strength is great practical significance in energy-savings fire-prevention for buildings. Herein, we reported the fiber-reinforced polybenzoxazine (PBO) composites flame retardance insulation, which were prepared under room temperature atmospheric pressure, using 4,4′-diaminodiphenlymethane (MDA) benzoxazine monomer as raw material oxalic acid (OA) catalyst. Several...
The recent discovery of superconductivity in La$_3$Ni$_2$O$_{7-\delta}$ with a transition temperature $T_c$ close to 80 K at high pressures has attracted significant attention, due particularly possible density wave (DW) occurring near the superconducting dome. Identifying type DW order is crucial for understanding origin this system. However, owing presence La$_4$Ni$_3$O$_{10}$ and other intergrowth phases samples, extracting intrinsic information from La$_3$Ni$_2$O$_7$ phase challenging....
Nanoporous silica aerogels have great potential in the application of thermal insulation. However, commonly used supercritical drying technology nanoporous has disadvantages such as high cost, complexity, and harsh conditions. Herein, a template orientation strategy been proposed for fabricating aerogel-like monoliths (ASMs) based on low-cost, rapid ambient without additional treatments surface modification solvent exchanging. The successful implementation depends slurry, which is composed...
As a promising high-temperature thermal insulation, carbon aerogel is generally prepared by the carbonization of an organic aerogel. However, preparation processes solvent exchange and supercritical drying are complicated contaminated, which hinder their large-scale production application in field civil insulators. Herein, nanoporous aerogels were environmentally friendly method ambient pressure without with usage water as solvent, acetic acid catalyst, biopolymer chitosan cross-linking...

Nitrogen gas adsorption curves SEM...
Ab initio calculations are performed to investigate the spin-polarized transport properties of bare and hydrogenated zigzag silicene nanoribbons (ZSiNRs). The results show that ZSiNRs with symmetric (asymmetric) edges prefer ferromagnetic (antiferromagnetic) as their ground states semiconductor properties, while accordingly antiferromagnetic (ferromagnetic) exhibit metallic behaviors. These facts result in a giant magnetoresistance behavior between low bias-voltage regime. Moreover,...
