Influence of thermal process on microstructural and physical properties of ambient pressure dried hydrophobic silica aerogel monoliths

Author(s): , , , , , , ,

Ambient pressure dried hydrophobic silica aerogel monoliths were prepared via simultaneous solvent exchange and surface modification in order to minimize volume shrinkage and density. At room temperature, the obtained silica ...

Ultrathin BN nanosheets with zigzag edge: one-step chemical synthesis, applications in wastewater treatment and preparation of highly thermal-conductive BN-polymer composites

Author(s): , , , , , ,

Ultrathin boron nitride nanosheets (BNNSs) were prepared at 300°C by a new variable-pressure one-step synthesis. An increase in pressure during the synthesis results in a decreased thickness for the nanosheets, ...
