Abstract: Method of forming colloidal lignin particles, comprising the step of dissolving lignin in a mixture of organic solvents, feeding of the said solution into water, and forming acolloidal dispersion of lignin. The used solvents are recovered with methods such as distillation and reused in the process. Water is removed from the colloidal dispersion by ultrafiltration and reused in the process. The concentrated colloidal dispersion is dried by spray drying. The invention can be used in applications where the colloidal nature of lignin will afford an advantage over bulk lignin.

Abstract: Method of forming functionalized colloidal lignin particles, comprising the step of providing lignin in a dissolved form, aldehyde functionalizing lignin, forming a colloidal dispersion of lignin, partially removing organic solvents and heat-curing the dispersion. The concentrated colloidal dispersion is dried by spray drying. The invention can be used in applications where the functioned and colloidal nature of lignin will afford an advantage over bulk lignin.

Abstract: Various example embodiments relate to enhancing excitation and output power in multi-transmitter wireless power transfer system. Transmitter coils are arranged such that they are substantially uncoupled from each other. The transmitter coils are activated one by one to measure induced voltage across adjacent transmitter coils. The induced voltages are used to determine mutual inductance ratios of transmitter-receiver pairs to obtain current distribution coefficients indicative of the position of the receiver for optimal excitation. A device, a method, and a computer program are disclosed.

Abstract: A filter system and method for filtering. The filter system (SJ) having at least two filters (S1, S2) having filter elements for filtering a material to be filtered. The material to be filtered is conducted to a dirty side (LP) of the filter and filtered material is conducted out from a clean side (PP) of the filter. A clogged filter is washed by counterflow washing in which the filtered material is conducted from the clean side of one filter to the clean side of another filter.
