    Abstract: A method of generating a refined a sugar stream that comprises xylose from a biomass hydrolysis solution, including contacting a biomass hydrolysis solution that includes a population of mixed sugars comprising xylose, an acid, and impurities, with a thermally-phase separable solvent such as a glycol solvent to form an extraction mixture; and separating from said extraction mixture a first stream including the thermally-phase separable solvent, acid, and impurities and a second, refined sugar stream that comprises xylose.

    IPC: C02F3/34

    Abstract: The present invention relates to a process for the controlling the sodium and sulfur levels in a pulp mill, comprising the steps of: a) providing a pulp mill stream comprising sulfide and having a total alkali concentration of at least 2 Molar; b) supplying a portion of the pulp mill stream to a reactor comprising sulfide oxidizing bacteria and removing sulfide from the pulp mill stream by subjecting said stream to sulfide oxidizing bacteria in the presence of oxygen, and at a pH in the range 8 to 11, to oxidize the sulfide to elemental sulfur, c) withdrawing from the reactor a treated pulp mill stream comprising sulfur, wherein the portion of the pulp mill stream is mixed with a portion of the sulfide oxidizing bacteria present in the reactor prior to supplying the pulp mill stream to the reactor in step b).

    Abstract: A method (200, 300, 500) for producing an electrically conductive pattern on substrate (202, 402), comprising: providing electrically conductive solid particles onto an area of the substrate in a predefined pattern (508), where the pattern (403) comprises a contact area (404B) for connecting to an electronic component and a conductive structure (404A) having at least a portion (414) adjacent to the contact area, heating the conductive particles to a temperature higher than a characteristic melting point of the particles to establish a melt (510), and pressing the melt against the substrate in a nip, the temperature of the contact portion of which being lower than the aforesaid characteristic melting point so as to solidify the particles into essentially electrically continuous layer within the contact area and within the conductive structure in accordance with the pattern (512), wherein the thermal masses of the contact area and the at least adjacent portion of the conductive structure are configured substantially equal.

    Abstract: The present invention is directed to a film comprising a base film which has been coated on at least one side with a coating that enhances gas and/or moisture barrier properties, wherein the base film comprises a fiber material and at least 60% by weight of said fiber material is microfibrillated cellulose, and the thickness of the coating is from 0.05 to 20 μm. The invention is also directed to products using said film. Such products are in particular packages suitable for sensitive objects that need to be packaged in a controlled or modified atmosphere. The film is also useful for other purposes, such as in the manufacture of balloons.
