PTFE Safety Debate

While cookware using polytetrafluoroethylene (PTFE) has been around since the 1960s its safety has become the subject of debate in recent years The majority of the discussion has revolved around a substance called perfluorooctanoic acid or PFOA This acid is used in the production of many fluoropolymers including PTFE In 2003 the Environmental Working Group petitioned the U S

Novel Ni

relation to the pyrolysis-gasification of a wood sawdust /polypropylene mixture was investigated The highest hydrogen yield of 39 6 mol H2/g Ni with H2/CO ratio of 1 90 was obtained in the presence of the Ca containing catalyst of molar ratio Ni:Mg:Al:Ca = 1:1:1:4 calcined at 500 C

Frontiers

Lignin the second most abundant biopolymer on the planet serves land-plants as bonding agent in juvenile cell tissues and as stiffening (modulus-building) agent in mature cell walls The chemical structure analysis of cell wall lignins from two partially delignified wood species representing between 6 and 65% of total wood lignin has revealed that cell wall-bound lignins are virtually

In oxygen deliginification research preliminary studies with xylanases indicated that approximately 80% of a birch xylan can be degraded to xylose suggesting that pretreatment may help to free the desired cellulose of hemicelluloses and provide the hemicellulose component in a useful form Computational docking studies of lignin-carbohydrate models with enzymes including laccases and

The Use of Cellulose Nanofillers in Obtaining Polymer
