Marine pollution caused by frequent oil spill accidents has brought about tremendous damages to marine ecological environment. Therefore, the facile large-scale preparation of three-dimensional (3D) porous functional materials with special wettability is in urgent demand. In this study, we report a low-cost and salt-tolerant superoleophobic aerogel for efficient oil/seawater separation. The aer...

In the present study, white kaolin-derived silica (SA) and silica-carbon aerogel composite (CSA) were successfully synthesised as useful adsorbents for effective removal of benzene from dry wet gas streams. The physicochemical features characterised using SEM, BET, XPS, TGA, adsorption properties investigated through breakthrough time curves equilibrium study. specific surface areas SA CSA 628 ...

Taking the defects of narrow range particle gradation glazed hollow beads and low mechanical strength silica aerogel into consideration, bead have been mixed for composite aggregate insulation mortar. Some measures, such as gradation, were taken to optimize properties formulation, analyzing kinds factors that influence on mortar thoroughly, properties, thermal fire-resistance properties. Under ...

The heat capacity of pure 3He in low density aerogel is measured at 22.5 bars. The superfluid response is simultaneously monitored with a torsional oscillator. A slightly rounded heat capacity peak, 65 microK in width, is observed at the 3He-aerogel superfluid transition, T(ca). Subtracting the bulk 3He contribution, the heat capacity shows a Fermi-liquid form above T(ca). We can fit the heat c...
