Abstract: Functional properties of nanophase materials are different from conventional materials, which determined the related technology for the rapid development and wide application space. Nanophase materials have been widely used in sports stadiums, sports turf, athletics track, sports clothing, sports equipment and sports supplements, and so on. At the same time, there may be a negative effect of nanophase materials on cell, lung, liver, kidney and brain. Therefore, the biological study of nanophase materials should also be strengthening.

Abstract: Lignin can be used as a cheap raw material to prepare organic and carbon aerogels based upon the sol-gel reactions. Different concent lignin organic aerogels have been prepared by sol–gel polymerization of formaldehyde with resorcinol, following by the process of RF-gel production and subsequent freeze drying. The resulting materials were characterized by FT-IR analysis, nitrogen adsorption, transmission electron microscopy and Scanning electron micrographs. The structural properties organic aerogel depend on the amount of lignin added to the sol-gel system. and the LRF aerogels obtained in the experimental have an open cell structure with continuous porosity and homogeneous spherical particles.
