The invention is the synthesis and use of epoxidized lignin (EL) preferably with but also without colloidal lignin nanoparticles (CLP, plural CLPs). The invention is divided in two parts, synthesis and utilization. The synthesis of the invention is performed in the following general steps: Preparation of an aqueous solution of lignin and a base. Combining the lignin solution with epichlorohydrin at 1-90° C., where the amount of epichlorohydrin should be within 1-20 ml per gram of lignin. Allowing the epoxidation reaction to take place between 1 minutes to 5 hours, while stirring the mixture. Removal of excess epichlorohydrin from epoxidized lignin solution by e.g. solvent extraction. EL functions as a cross-linker and may be used e.g. to prepare adhesives, surface coatings, and composite materials. EL may also be used as foaming agent in water-based solutions.

The inventive device is a mechanical wave inducing device being connectable to a needle. The device has a displacement source and a driving signal connection part in order to connect the displacement source to a signal source. The device has also two connections parts, which are connected to the displacement source, and which each wing part has a connection point to be attached with the needle. The wing parts are converters in order to convert longitudinal mechanical wave movement created by the displacement source into transversal mechanical wave movement for the needle, and at least one connection point is designed to match the transversal mechanical waves to the needle.

Colored lyocell type fibers comprising respun coloured recycled fibers and method of producing the same. According to the method a raw-material of colored recycled textile fibers is provided and dissolved in an ionic liquid to provide a spinning dope. By spinning the dope using dry jet-wet spinning colored respun textile fibers can be manufactured. The invention provides for the simultaneous recycling of cellulose fibers and dyes from dyed cotton waste in the form of dyed lyocell fibers.

Disclosed is a method for quantification of water and/or one or more ionic liquid components in an ionic liquid (IL)/water (H2O) mixture. The method comprises obtaining one or more Raman spectra for the IL/H2O mixture, and using a quantitative calibration model with the one or more Raman spectra to quantify water and/or one or more ionic liquid components in the IL/H2O mixture.

There is provided a microscope comprising a micromanipulator, comprising a first electromagnet comprising a first magnetic core; a second electromagnet comprising a second magnetic core, wherein the first magnetic core and the second magnetic core are configured to generate a magnetic force on magnetic probes arranged within a biological matrix arranged in between the first magnetic core and the second magnetic core; and wherein the microscope comprises imaging means configured to capture images of the biological matrix comprising the magnetic probes for detection of displacements of the magnetic probes caused by the magnetic force.

Disclosed is a multi-locus TMS (transcranial magnetic stimulation) transducer, including one or more transducer modules configured (i.e., adapted) to be positioned on a scalp of a subject for TMS, each of the one or more transducer modules including five or more coils for TMS of a cortical target of a subject.
