Abstract: The present disclosure relates to a method for the production of precursor fiber for the production of carbon fiber, comprising the steps: a) a) forming a spinning dope comprising a dissolving pulp, a lignin and an alkali metal hydroxide dissolved in water (s201); 5 b) extruding the spinning dope through a spinning nozzle to provide a fibrous extrudate (s203); and c) passing the fibrous extrudate through a coagulation liquid to provide the precursor fiber (s205); wherein the coagulation liquid is arranged to effect precipitation of the precursor fiber by regulation of pH and/or ionicity. The disclosure further relates to precursor fibers and carbon fibers produced by the method above, as well as spinning dopes used in the method.

Abstract: The present invention relates to a method of producing holocellulose fibres by treating a wood-based raw material with an organic peroxide, wherein the method comprises charging the organic peroxide continuously to the wood-based raw material during the treatment and/or charging the organic peroxide to the wood-based raw material in at least two separate steps with an intermediate alkaline treatment step. Additionally, a process for the production of paper comprising the steps of preparing a papermaking stock comprising an aqueous pulp slurry comprising cellulosic fibres and having a fibre consistency of from 0.1 to 40% by weight, wherein the cellulosic fibres comprise or consist of holocellulose fibres, and wherein the amount of the wood-based holocellulose fibres is from 0.5 to 100% by weight, based on the total weight of the stock; providing the stock to a wire and form a web; dewatering the web; and drying the web is claimed. By the method affordable way to produce holocellulose fibres usable in the process to provide paper with high strength is provided, while effective dewatering can be obtained during the manufacturing process.

Abstract: A semiconductor device (1) is provided and a method of manufacturing the same. The method comprising providing a substrate (2) having formed thereon or therein a main junction (3). The method further comprises forming a junction termination structure (5) comprising a plurality of junction termination paths (8b-8g), wherein each path comprises an implanted region (9b-9g) having an implanted width. The step of forming a junction termination structure further comprises determining an individual width for each implanted width and a single first dopant dose which corresponds to an individual effective sheet charge concentration for each path such that, when said semiconductor device is in use, a desired electric field distribution over the second region of the semiconductor device is achieved. The step of forming a junction termination structure further comprises doping the implanted regions, each having the individual width, with dopants according to said first single dopant dose.
