Specialized (iso)eugenol-4-O-methyltransferases (s-IEMTs) and methods of making and using the same

Title: Specialized (iso)eugenol-4-O-methyltransferases (s-IEMTs) and methods of making and using the same

Specialized (iso)eugenol 4-O-methyltransferase (s-IEMT) enzymes having increased capacity for methylation of monolignols are disclosed. The s-IEMTs have unique activity favoring methylation of coniferyl alcohol versus sinapyl alcohol. Various s-IEMTs methylate ferulic acid. Means for producing the various s-IEMTs are provided. The s-IEMTs are useful for modification of lignin content and production of aromatic compounds.

Modified carbohydrate-chitosan compounds, methods of making the same and methods of using the same

Patent Venditti, Richard A ; Pawlak, Joel J ; Salam, Abdus ; El-Tahlawy, Khaled Fathy

Compositions of matter are provided that include chitosan and a modified carbohydrate. The modified carbohydrate includes a carbohydrate component and a cross linking agent. The modified carbohydrate has increased carboxyl content as compared to an unmodified counterpart carbohydrate. A carboxyl group of the modified carbohydrate is covalently bonded with an amino group of chitosan. The compositions of matter provided herein may include cross linked starch citrate-chitosan and cross linked hemicellulose citrate-chitosan, including foams thereof. These compositions yield excellent absorbency and metal chelation properties. Methods of making cross linked modified carbohydrate-chitosan compounds are also provided.

Rare earth/iron fluoride and methods for making and using same

Patent Schmidt, Frederick A. ; Wheelock, John T. ; Peterson, David T.

A particulate mixture of Fe.sub.2 O.sub.3 and RE.sub.2 O.sub.3, where RE is a rare earth element, is reacted with an excess of HF acid to form an insoluble fluoride compound (salt) comprising REF.sub.3 and FeF.sub.3 present in solid solution in the REF.sub.3 crystal lattice. The REF.sub.3 /FeF.sub.3 compound is dried to render it usable as a reactant in the thermite reduction process as well as other processes which require an REF.sub.3 /FeF.sub.3 mixture. The dried REF.sub.3 /FeF.sub.3 compound comprises about 5 weight % to about 40 weight % of FeF.sub.3 and the balance REF.sub.3 to this end.

Carbon Nanotube-Containing Structures, Methods Of Making, And Processes Using Same

Patent Wang, Yong ; Chin, Ya-Huei ; Gao, Yufei ; Aardahl, Christopher L. ; Stewart, Terri L.

Carbon nanotube structures are disclosed in which nanotubes are disposed over a porous support such as a foam, felt, mesh, or membrane. Techniques of making these structures are also disclosed. In some of these techniques, a support is pretreated with a templated surfactant composition to assist with the formation of a nanotube layer.
