The effect of organic expanders including humus acid, lignin,vio-lanthrone and isoviolanthrone on the performances of the lead-acid battery are described.
The changes in chemical structure of residual lignin in reed kraft pulp after treatment with a white rot fungus,Panus conchatus have been investigated in the present paper.
Moreover, it was shown that degradation of lignin was promoted by veratryl alcohol added, no effect of veratryl alco-hol on degradation of cellulose and hemicellulose was detected.
That means the birch from high longitude and latitude areas will have lower content of the ash, extraction and lignin, higher content of the holocellulose and pentosan in the wood.
Velev and Ph.D. student Alexander Richter discovered that silver-based nanoparticles can be replaced with non-harmful nanoparticles based on an organic polymer called lignin, naturally found in most plants.
