Abstract: Embodiments of the invention relate to a control system of a first entity. The control system has a forecast module that creates a supply medium plan of a supply medium unit of the first entity. The supply medium unit is a supply medium consumer, a supply medium producer, and/or supply medium storage. The supply medium unit connects to a physical supply channel network. A peer-to-peer module receives at least one supply medium offer message of a further entity by communicating with a peer-to-peer application of a peer-to-peer network. The peer-to-peer module causes generation of a supply medium transaction agreement about the physical exchange of a supply medium between the first and further entity through the peer-to-peer application based on the supply medium plan and the supply medium offer message. A controlling module controls the supply medium unit in dependence of the generated supply medium transaction agreement.

Abstract: A process for producing a titanium-containing silicon oxide catalyst having a silicon-carbon-silicon bond, silicon-oxygen-silicon bond and silicon-oxygen-titanium bond which includes causing a silicon compound of the following formula (1) and a titanium alkoxide compound to gel in a water and/or alcohol solvent and removing the solvent in the resulted gel by extraction with a supercritical fluid (R1 to R7 each independently represent a hydrocarbon group having 1 to 20 carbon atoms.).

Abstract: A process for producing an oxirane compound by reacting an olefin with hydroperoxides in the presence of a catalyst wherein said catalyst is obtained by gelling a silicon compound of the following formula (1) (silicon compound (1)), a silicon compound of the following formula (2) (silicon compound (2)) and a titanium compound in water, alcohol solvent or mixed solvent of water and alcohol, removing a solvent in the resulted gel by extraction with supercritical fluid, then, performing drying and silylation treatment: Si(OR1)4  (1) (R2)mSi(OR3)4−m  (2) (R1, R2 and R3 independently represent a hydrocarbon group having 1 to 20 carbon atoms. m represents an integer of 1 or 2.
