Abstract: A method of determining surface properties of interest of a surface. The method comprises providing a magnetic liquid and applying it onto a part of the surface in the form of a droplet. The droplet contacts the surface and it is subjected to a magnetic field. The lateral position of the magnetic field maximum is changed relative to the surface to drag the drop magnetically along a predetermined length of the surface following a path. The retentive force exerted on the droplet during its movement is measured in order to collect data as the drop moves along the surface, and the surface properties of interest are determined from the collected data. The method can be used for studying wetting properties and, in one embodiment, the method is used for assessing homogeneity and potential contamination of a surface.

Abstract: The invention concerns a method for joining a metal component and a polymer component, and a structure comprising said components. In the method, an extrusion die plate with a through hole is placed between the metal component and the polymer component. A probe is rotated and plunged across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component. The probe has a rotation axis having an offset to the centre of the through hole during the rotating and plunging action.

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: The present invention relates to typically homogeneous gel-like cellulose-based fiber products which do not contain hemicellulose but may nevertheless contain lignin. The invention relates also to a method for the production of such fibrous products, in which microcrystalline cellulose (MCC) is mixed into oil or water to form a fiber mixture, and is degraded into homogeneous form by mechanical treatment.

Abstract: A method and device for non-invasive monitoring of the temperature of the retina and the retinal pigment epithelium inside the eye, particularly during heating of the bottom of the eye, wherein alternating probing short-duration pulses of light, one at wavelength close to the absorption maximum of the photoreceptor cell type and the other at wavelength in the near-infrared region, are directed at the retinal tissue at appropriate time intervals. Photoreceptor cell electrical signals, photoresponses, are recorded using electroretinography (ERG) and the changes in retinal temperature are determined from changes in photoresponse kinetics and changes in photoreceptor sensitivity to the stimuli. The method is especially applicable at temperatures up to 45° C. for humans and for other animals.
