    摘要: The current invention includes a composition having stability additives of selected inorganic salts and/or organic incorporated into an aldehyde-functionalized polymer product. The stability additive can be post added to the finished polymer product, added to the reaction vessel prior to inducing functionalization of the non-functionalized polymer, or added at any stage during the functionalization reaction. Methods for forming the composition and using the composition to produce a cellulosic fiber-based medium are also disclosed.

    摘要: A process for hydrogen production by water electrolysis and a process of depolarizing the anode of a water electrolysis cell by oxidizing a biomass product which may be monosaccharides, lignins, and mixtures thereof. The process of this invention avoids molecular oxygen evolution and results in high purity hydrogen at cell potentials substantially less than required for normal water electrolysis involving oxygen evolution. The process utilizes biomass products which are readily available and cost effective. High consumption of biomass product is achieved with an anode of lead-rich ruthenium polychlore compounds.
