FOCUS using a membrane that combines water treatment and biotechnologies to produce ethanol through continuous fermentation process by recycling microorganisms using biomass generated at sugar cane sugar factories. The demonstration enables efficient production of ethanol from sugarcane i.e., about 10 times faster than the existing process and at the same time to increase production of ethanol as it improves yields by 10-20%. For the future, Toray will offer this technology to Brazil, India and Thailand, the countries where ethanol production using sugar cane is advanced and promote development of further mass production technology to put it into practical use within five years. The membrane-integrated fermentation process is a technology to enable exponential improvement in fermentation efficiency by using water treatment separation membrane in fermentation process. It contributes to the realization of efficient production of nonpetrochemical ingredients based on biomass. Toray has been promoting research and technology development of a membraneintegrated fermentation process, which is a process to carry out continuous fermentation by recycling microorganisms with fermentation reactor embedded with a highly water permeable, highly durable polyvinylidene difluoride (PVDF) separation membrane that Toray has developed. To be sure, practical application of the membrane-integrated fermentation process requires sophisticated countermeasures against bacterial contamination, as it requires a long fermentation period compared with the conventional batch fermentation process. To develop its original continuous fermentation process, it adopted the process in the scaling up demonstration facility installed at its Tokai Plant and had been driving forward the scaling-up demonstration in the Low Carbon Technology Research and Development Program (Ministry of the Environment, Japan) (Producing bioethanol and co-products from waste materials in domestic cane sugar factories). Further, Toray succeeded in obtaining new yeast suitable for continuous fermentation and subsequently in combining these technologies for scaling-up demonstration of continuous fermentation, at a production speed 10 times faster than batch fermentation process, for about one month without bacterial contamination. The ethanol produced using this technology is of a high quality and suitable for use as bioethanol fuel and can be put into practical use through technology derived in these countries.

oxide comprised of oxygen, cerium, and one or more second metals. In some instances, the cerium is 10 to 80 molar % of the metals in the metal oxide and/or the catalyst includes two or more second metals. The OER catalyst can be included in or on an electrode. The electrode can be arranged in an oxygen evolution system such that the Oxygen Evolution Reaction occurs at the electrode.

Coated substrates for use in catalysis and catalytic converters and methods of coating substrates with washcoat compositions The patent discloses methods of forming coated substrates for use in catalytic converters, as well as washcoat compositions and methods suitable for using in preparation of the coated substrates, and the coated substrates formed thereby. The catalytic material is prepared by a plasma-based method, yielding catalytic material with a lower tendency to migrate on support at high temperatures, and thus less prone to catalyst aging after prolonged use. Also disclosed are catalytic converters using the coated substrates, which have favorable properties as compared to catalytic converters using catalysts deposited on substrates using solution chemistry. Also disclosed are exhaust treatment systems, and vehicles, such as diesel vehicles, particularly light-duty diesel vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.

Organocatalysis in Ionic Liquids Using organic molecules to promote reactions is an attractive option as these organic molecules can be safer than metalbased options. However, it is still important to be able to recycle and reuse these organic promoters. Ionic liquids provide this opportunity. This book provides a current overview of the underexplored area of the use of room temperature ionic liquids as organocatalysts for a range of organic reactions, including polymerizations.

Mesoporous Materials for Advanced Energy Conversion and Storage Technologies Innovation through specific and rational design and functionalization has led to the development of a wide range of mesoporous materials with varying morphologies (hexagonal, cubic, rod-like), structures (silicates, carbons, metal oxides), and unique functionalities (doping, acid functionalization). The ability to precisely design such a wide variety of materials makes this field among the most exciting in materials science. This book focuses primarily on the rapid progress in their application in energy conversion and storage technologies, including supercapacitor, Li-ion battery, fuel cells, solar cells, and photocatalysis (water splitting) and will serve as a valuable reference for researchers in the field.
