摘要:
A thin film structure, method of producing it and the use thereof. The thin film structure comprises a substrate with a thin conductive layer containing an oxidizing enzyme mixed with an electron transfer mediator. The thin layer is protected against wetting to allow for its storage in dry conditions and further being sufficiently porous to allow for immediate activation of the oxidizing enzyme when contacted with an aqueous solution. The thin film can be used as a cathode in electrochemical fuel cells.

摘要:
The present invention concerns a process for manufacturing a thermoformable plasticized composite containing cellulose fiber and polylactide by blending the dry cellulose fiber and a compatibilizer in a compactor into pellets, and subsequently reacting the reactive compatibilizer and the mixture of cellulose fiber and polylactide by compounding. The invention also concerns a composite manufactured using said process, as well as further processed products.

摘要:
The present invention concerns a process for the mechanical or mechano-chemical treatment of biomass, wherein a mixture containing the biomass and optional further chemicals is pressed through the openings of one or more compactor one or more times. The process can be operated in a continuous manner by using more than one compactor and more than one compacting cycle, whereby the multiple compactors are operated sequentially.
摘要:
A process of producing a fibrous composition, which includes a first component that comprises vegetable fibres and a second component that consists of a synthetic, electrically conductive polymer. According to the method, the vegetable fibres comprise porous, loose and separate fibres, and the electrically conductive polymer is an independently electrically conductive polymer which is doped in order to generate charge carriers in the polymeric material, the synthetic polymer being produced by in situ—polymerization inside the fibres and on their surfaces. The doping agent is an organic sulphonic acid which is allowed to absorb into the fibres in an aqueous medium, and after that a monomer corresponding to the polymer is brought into contact with the fibres and polymerised. By means of the invention, the electrically conductive polymers are attached to fibres so firmly that they are not substantially out-washable by water.
