摘要： A method of preparing an aqueous dispersion comprising silver particles of mean diameter from 0.5 to 25 nm by weight and an aqueous carrier liquid, including the steps of i) providing a mixture comprising at least one silver salt, aqueous carrier liquid and a stabiliser for the particles ii) contacting the mixture with a non-ionic or covalent reducing agent to form a reaction mixture iii) causing the at least one silver salt to react with the reducing agent to form a dispersion comprising silver particles and acid wherein step iii) is partly or completely performed in the presence of anion exchange resin whereby the acid is exchanged for a hydroxide ion from the resin and/or is sorbed by the resin.

摘要： There is disclosed a material processing method wherein a material is fed between a pair of opposed moving surfaces which converge such that a nip is defined therebetween, whereby the material is drawn into the nip to be compressed or compacted between the surfaces, and thence output from between the surfaces, the method comprising subjecting the material to an asymmetric and/or non uniform flow condition between the surfaces to effect shearing in the material in a direction generally parallel to the direction of flow of the material between the surfaces.
