Fumed silica, due to the thixotropic properties and low thermal conductivity, is used in insulation products. Exposure to crystalline silica is of most concern and there is also evidence that exposure to nanometer-sized fumed silica may lead to adver

CNTs were grown on iron-modified mesoporous graphitized carbon aerogel (GCA) at 700 °C, 800 °C and 900 °C using catalytic CVD method. Resultant CNT/GCA materials composition, morphology and structure were studied to understand their electrochemica

Aspen Aerogels has developed a novel solid sorbent for CO2 capture using amine functionalized aerogel (AFA) that has demonstrated a lower specific heat capacity (0.7–1.1 J/g·K) than aqueous amines (∼4.2 J/g·K). In addition, the AFA material has

Nitrogen enriched carbon aerogels and Co-based non-noble metal catalysts supported on carbon aerogels have been synthesized and tested using XPS, HRTEM, XRD and RDE techniques. XPS spectra of unmodified carbon aerogels indicated a presence of two oxy

Mesoporous carbon aerogel has been impregnated with iron (10 and 15 wt. %) as a catalyst for graphitization by wet incipient method. The iron modified and non-modified carbon aerogels were heat treated at 900°C, 1200°C, and 1400°C in argon. The cr
